configure: error: in `/home/CLi/develop/buildroot/buildroot-2013.05/output/build/host-libtool-2.2.10′:

configure: error: C compiler cannot create executables

【解决过程】

1.去看了看，是有对应的gcc的：

CLi@PC-CLI-1 ~/develop/buildroot/buildroot-2013.05
$ ls /usr/bin/gcc
/usr/bin/gcc*

CLi@PC-CLI-1 ~/develop/buildroot/buildroot-2013.05
$ ls /usr/bin/gcc -lha
-rwxr-xr-x 3 CLi Domänen-Benutzer 507K Jun 16 12:50 /usr/bin/gcc*

2.再去看看对应的config.log：

D:\tmp\tmp_dev_root\cgwin\home\CLi\develop\buildroot\buildroot-2013.05\output\build\host-libtool-2.2.10\config.log

内容为：

This file contains any messages produced by compilers while
running configure, to aid debugging if configure makes a mistake.

It was created by libtool configure 2.2.10, which was
generated by GNU Autoconf 2.65.  Invocation command line was

  $ ./configure --prefix=/home/CLi/develop/buildroot/buildroot-2013.05/output/host/usr --sysconfdir=/home/CLi/develop/buildroot/buildroot-2013.05/output/host/etc --enable-shared --disable-static --disable-gtk-doc --disable-doc --disable-docs --disable-documentation --with-xmlto=no --with-fop=no

See `config.log' for more details.

对应的，可以看到：

其是用：

/usr/bin/gcc –version

结果configure的3516行，无法判断出结果：$? = 0

然后又去：

/usr/bin/gcc -v

结果还是configure的3516行，无法判断出结果：$? = 0

5.所以，自己去看看，对应的

D:\tmp\tmp_dev_root\cgwin\home\CLi\develop\buildroot\buildroot-2013.05\output\build\host-libtool-2.2.10\configure

中的3516行是啥。

$as_echo "$as_me:${as_lineno-$LINENO}: \$? = $ac_status" >&5

相关部分的内容是：

test -z "$CC" && { { $as_echo "$as_me:${as_lineno-$LINENO}: error: in \`$ac_pwd':" >&5
$as_echo "$as_me: error: in \`$ac_pwd':" >&2;}
as_fn_error "no acceptable C compiler found in \$PATH
See \`config.log' for more details." "$LINENO" 5; }

# Provide some information about the compiler.
$as_echo "$as_me:${as_lineno-$LINENO}: checking for C compiler version" >&5
set X $ac_compile
ac_compiler=$2
for ac_option in --version -v -V -qversion; do
  { { ac_try="$ac_compiler $ac_option >&5"
case "(($ac_try" in
  *\"* | *\`* | *\\*) ac_try_echo=\$ac_try;;
  *) ac_try_echo=$ac_try;;
esac
eval ac_try_echo="\"\$as_me:${as_lineno-$LINENO}: $ac_try_echo\""
$as_echo "$ac_try_echo"; } >&5
  (eval "$ac_compiler $ac_option >&5") 2>conftest.err
  ac_status=$?
  if test -s conftest.err; then
    sed '10a\
... rest of stderr output deleted ...
         10q' conftest.err >conftest.er1
    cat conftest.er1 >&5
  fi
  rm -f conftest.er1 conftest.err
  $as_echo "$as_me:${as_lineno-$LINENO}: \$? = $ac_status" >&5
  test $ac_status = 0; }
done

但是结果也看不太懂。

6.去搜：

buildroot libtool compiler cannot create executables

找到的：

[Xenomai-help] User space build problems with Xeno 2.5.2 and ARM integrator

和

svn commit: [25880] trunk/buildroot/package: automake libtool pkgconfig

说是少了相关的库而导致的。

所以此处去看看此处的：

D:\tmp\tmp_dev_root\cgwin\home\CLi\develop\buildroot\buildroot-2013.05\output\build\host-libtool-2.2.10\config.log

但是也没找到什么库相关的。

不过看到：

$ ./configure --prefix=/home/CLi/develop/buildroot/buildroot-2013.05/output/host/usr --sysconfdir=/home/CLi/develop/buildroot/buildroot-2013.05/output/host/etc --enable-shared --disable-static --disable-gtk-doc --disable-doc --disable-docs --disable-documentation --with-xmlto=no --with-fop=no

感觉其中的–enable-shared –disable-static

好像或许和此处错误有关？

7.此人：

[SOLVED] configure: error: C compiler cannot create executables

是重新修复gcc后而解决问题的。

但是我此处，cygwin中，gcc，也一直是好的，也不方便重新安装。所以暂时不去尝试重装gcc。

8.参考了：

can not emerge libtool error: C compiler can not create exec

提到的：

GF20: C compiler cannot create executables

但是好像解释的和此处没啥关系：

其是说，gcc各种arch，CFLAGS等问题。

我此处是：

checking for C compiler version

部分出错的。

9.看了：

D:\tmp\tmp_dev_root\cgwin\home\CLi\develop\buildroot\buildroot-2013.05\output\build\host-libtool-2.2.10\config.log

还是去找找：

configure:3516: $? = 0

现象的背后根本原因吧。

即，到底configure的逻辑是什么样的，而导致此处会出现$? = 0

10.找了半天，参考：

checking whether the C compiler works… no Oooops !!

中的那人的提示：

中，也找到了是：

很明显，是此处cygwin下的cc1.exe，不支持动态库？

或者是动态库的路径，没有添加进来，导致找不到。

11.参考：

Re: hard-coded library search path in gcc-4

去试试

cygcheck /usr/lib/gcc/i686-pc-cygwin/4.7.3/cc1.exe

12.参考的很多帖子，都是缺少的是mpfr：

cygwin configure错误

Win7下NS2 2.35安装求助

但是我此处不是，我的是：

cannot open shared object file: No such file or directory

13.所以去搜：

i686-pc-cygwin cc1.exe error cannot open shared object file: No such file or directory

14.看到：

gcc4.7.2 cc1 error while loading shared libraries

说是4.7.2的gcc不是足够稳定：

需要测试其所依赖的所有的东西的版本：

要么我们都把对应所依赖的版本都安装上

要么先降级gcc为一个低版本的，比如4.5.3之类的

而我当前的是4.7.3的gcc：

CLi@PC-CLI-1 ~/develop/buildroot/buildroot-2013.05
$ gcc-4 --version
gcc-4 (GCC) 4.7.3
Copyright (C) 2012 Free Software Foundation, Inc.

warranty; not even for MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

那估计就是更加不稳定了？

而关于其所依赖的东西，通过：

cygcheck -c|grep gcc

去看看：

CLi@PC-CLI-1 ~/develop/buildroot/buildroot-2013.05
$

15.再参考其做法，也去弄个测试的helloworld.c去试试gcc-4，能否正常编译：

#include <stdio.h>

int main(void)
{
    printf("gcc-4 ok");
    return 0;
}

编译执行：

CLi@PC-CLI-1 ~/develop/buildroot/buildroot-2013.05
$ gcc-4 ../test_gcc_4/helloworld.c -o ../test_gcc_4/helloworld

CLi@PC-CLI-1 ~/develop/buildroot/buildroot-2013.05
$ ../test_gcc_4/helloworld
gcc-4 ok
CLi@PC-CLI-1 ~/develop/buildroot/buildroot-2013.05
$

很明显，都是正常的。

即此处的gcc-4，是正常的。

不存在那个帖子

gcc4.7.2 cc1 error while loading shared libraries

中所遇到的问题。

15.这人：

Re: Possible Windows 7 issue? cc1.exe: error while loading shared libraries: ?

貌似是通过：

怀疑缺少cyggcc_s-1.dll，然后手动拷贝到cygwin的/bin下面，结果就解决了问题。

而我此处，是正常的，不缺的：

CLi@PC-CLI-1 ~/develop/buildroot/buildroot-2013.05
$ ls /bin/cyggcc* -lha
-rwxr-xr-x 1 CLi Domänen-Benutzer 104K Jun 16 12:23 /bin/cyggcc_s-1.dll*
-rwxr-xr-x 1 CLi Domänen-Benutzer 6.1K Sep  2  2012 /bin/cyggccpp-1.dll*

16.此处，郁闷的是，

4.7.3/cc1.exe

只是报错：

cannot open shared object file: No such file or directory

但是却是只是输出个问号：

cc1.exe: error while loading shared libraries: ?: cannot open shared object file: No such file or directory

从而，不知道是缺少了那个库，从而不知道根本原因，也就没法解决了。

17.自己去手动执行一下那个命令：

CLi@PC-CLI-1 ~/develop/buildroot/buildroot-2013.05
$ cd output/build/host-libtool-2.2.10

CLi@PC-CLI-1 ~/develop/buildroot/buildroot-2013.05/output/build/host-libtool-2.2.10
$ pwd
/home/CLi/develop/buildroot/buildroot-2013.05/output/build/host-libtool-2.2.10

CLi@PC-CLI-1 ~/develop/buildroot/buildroot-2013.05/output/build/host-libtool-2.2.10
$ /home/CLi/develop/buildroot/buildroot-2013.05/output/host/usr/bin/ccache /usr/bin/gcc -O2 -I/home/CLi/develop/buildroot/buildroot-2013.05/output/host/usr/include -I/home/CLi/develop/buildroot/buildroot-2013.05/output/host/usr/include -L/home/CLi/develop/buildroot/buildroot-2013.05/output/host/lib -L/home/CLi/develop/buildroot/buildroot-2013.05/output/host/usr/lib -Wl,-rpath,/home/CLi/develop/buildroot/buildroot-2013.05/output/host/usr/lib conftest.c
gcc: error: conftest.c: No such file or directory

然后再想办法找到conftest.c，结果发现是在配置期间生成的。

即：

D:\tmp\tmp_dev_root\cgwin\home\CLi\develop\buildroot\buildroot-2013.05\output\build\host-libtool-2.2.10\configure

中的：

cat confdefs.h - <<_ACEOF >conftest.$ac_ext
/* end confdefs.h.  */

int
main ()
{

  ;
  return 0;
}
_ACEOF

所以，自己弄一个：

#include <stdio.h>

int
main ()
{

  ;
  return 0;
}

然后去测试：

CLi@PC-CLI-1 ~/develop/buildroot/buildroot-2013.05/output/build/host-libtool-2.2.10
$ /home/CLi/develop/buildroot/buildroot-2013.05/output/host/usr/bin/ccache /usr/bin/gcc -O2 -I/home/CLi/develop/buildroot/buildroot-2013.05/output/host/usr/include -I/home/CLi/develop/buildroot/buildroot-2013.05/output/host/usr/include -L/home/CLi/develop/buildroot/buildroot-2013.05/output/host/lib -L/home/CLi/develop/buildroot/buildroot-2013.05/output/host/usr/lib -Wl,-rpath,/home/CLi/develop/buildroot/buildroot-2013.05/output/host/usr/lib ~/develop/buildroot/libtool_test/conftest.c

很明显，是可以运行的，然后可以看到输出的a.exe文件的：

CLi@PC-CLI-1 ~/develop/buildroot/buildroot-2013.05/output/build/host-libtool-2.2.10
$ file a.exe
a.exe: PE32 executable (console) Intel 80386, for MS Windows

所以，这就很诡异了。

此处手动执行命令是OK的，但是make编译buildroot期间的libtool中自动执行，却不行。

18.再参考之前的：

Re: hard-coded library search path in gcc-4

去手动执行cc1试试：

CLi@PC-CLI-1 ~/develop/buildroot/buildroot-2013.05/output/build/host-libtool-2.2.10
$ /usr/lib/gcc/i686-pc-cygwin/4.7.3/cc1.exe

但是无任何输出，所以中断。

19.再去试试，PATH设置为空，然后执行cc1试试：

CLi@PC-CLI-1 ~/develop/buildroot/buildroot-2013.05/output/build/host-libtool-2.2.10

CLi@PC-CLI-1 ~/develop/buildroot/buildroot-2013.05/output/build/host-libtool-2.2.10
$

很明显，其是需要对应的

C:\Windows\system32

和，之前看到的：

D:\tmp\tmp_dev_root\cgwin\bin

即：

/bin

的路径的。

然后去看了看对应的：

D:\tmp\tmp_dev_root\cgwin\home\CLi\develop\buildroot\buildroot-2013.05\output\build\host-libtool-2.2.10\config.log

其中是包含system32的路径的，也有/usr/bin：

PATH: /usr/local/bin
PATH: /usr/bin
PATH: /cygdrive/c/Windows/system32
PATH: /cygdrive/c/Windows

但是还的确没有看到有/bin这个路径的。

难道是PATH中，缺少了/bin这个路径，而导致cc1找不到其所依赖的

D:\tmp\tmp_dev_root\cgwin\bin

即：

/bin

其下的各个dll库，比如：

cygcloog-0.dll

？？

20.那就：

（1）重新关于当前cygwin（因为已经把PATH设置为空了）

（2）去给PATH中添加对应的/bin路径：

修改.bashrc，改为：

PATH=/bin:$HOME/develop/crosstool-ng/x-tools/arm-xscale-linux-gnueabi/bin:/opt/crosstool-ng/bin:$HOME/develop/crosstool-ng/x-tools/armxscalecurl/bin:$PATH:/opt/gcc-4.0.4-glibc-2.3.6-kernel-2.6.17/sysroot-arm-xscale-linux-gnu/usr/include:/opt/gcc-4.0.4-glibc-2.3.6-kernel-2.6.17/sysroot-arm-xscale-linux-gnu/usr/include/linux

（3）重启cygwin，且去确认一下，路径中包含/bin：

CLi@PC-CLI-1 ~/develop/buildroot/buildroot-2013.05
$ echo $PATH

（4）进入buildroot，make clean一下。

再去make，看看最后到此libtool还是否会出错，如果出错，错误是否一样。

（5）此处，注意到一个现象：

内存占用，又是缓缓上升：

当前8G内存，已经从5.8G左右，变成6.07G左右了。

而之前cygwin下编译crosstool-ng，遇到类似的内存泄露的问题：

【未解决】用cygwin编译crosstool-ng，好像有内存泄露(memory leak)

所以，怀疑此处也是：

是cygwin本身的cc1相关的，内存泄露？

暂时不确定。以观后效。

（6）此刻已经占用6.22->6.42->6.66->6.85->7.04内存了。

然后觉得，还真有点可能是：

cygwin的内存泄露？

而导致内存占用太多，最后是使得cc1，找不到对应的cygwin中所依赖的库了。

从而报此错误。

（7）估计就是和之前：

【未解决】用cygwin编译crosstool-ng，好像有内存泄露(memory leak)

类似的：

Cygwin中（或许是cc1，ld等东西）有bug，导致内存泄露

导致：

编译（crosstool-ng，buildroot等）时间很长，占用内存比较多的话，

无法及时释放，导致内存被耗光（我的8G内存，被用掉7G多。。。）

导致后续出现各种问题：

比如

无法分配内存：之前遇到的：can not allocate memory

无法载入库：此处的cc1，无法找到所需要的库文件

解决办法是：

重启Win7，重新开始编译

-> 至少使得，内存相对较多，够其泄露的。。。

-> 或许最后可以一点点编译，知道编译成功吧。。

（8）但是结果证明：

不是cygwin的内存泄露问题：

此处编译到此处，还是问题依旧：

所以，还是程序问题。不是内存泄露问题（虽然内存泄露问题，貌似的确存在。）

21.还是重新Win7后，重新打开Cygwin，先

make clean

后，再去重新make编译，确保结果的确是此问题，而不是内存泄露问题。

现在，重新开始编译。

当前内存为3.15G。

22.突然想起来了。

此处错误是关于：

checking for C compiler version

的，而别的程序，应该也有类似的动作的。

所以去找了另外一个m4的：

D:\tmp\tmp_dev_root\cgwin\home\CLi\develop\buildroot\buildroot-2013.05\output\build\host-m4-1.4.16\config.log

看了看对应的相关部分的内容是：

很明显，此处的m4的：

结果就是正常的输出：

configure:4310: $? = 0
configure:4358: result: yes

而没有出现libtool的

/usr/lib/gcc/i686-pc-cygwin/4.7.3/cc1.exe: error while loading shared libraries: ?: cannot open shared object file: No such file or directory

所以此处的libtool，还是很奇怪。

23.想到了，会不会是由于此处libtool的configure文件有误。

所以去比较m4和libtool的两configure文件看看，（估计应该是正常的）

可以看到，对应的libtool的configure，在3516前后，和m4的一样，

但是前面的as_fn_error，少了一点输出。

所以，现在去手动把：

D:\tmp\tmp_dev_root\cgwin\home\CLi\develop\buildroot\buildroot-2013.05\output\build\host-libtool-2.2.10\configure

中的：

as_fn_error "no acceptable C compiler found in \$PATH
See \`config.log' for more details." "$LINENO" 5; }

改为：

as_fn_error $? "no acceptable C compiler found in \$PATH
See \`config.log' for more details" "$LINENO" 5; }

然后再去编译看看是否可以解决此问题。

结果问题依旧。

24.然后再去比较，两者此处的configure传入的参数配置如何。

正常的：

而出错的：

是：

看起来，m4的配置时，添加了很多对应的变量：

CC=/home/CLi/develop/buildroot/buildroot-2013.05/output/host/usr/bin/ccache /bin/gcc 
CFLAGS=-O2 -I/home/CLi/develop/buildroot/buildroot-2013.05/output/host/usr/include 
LDFLAGS=-L/home/CLi/develop/buildroot/buildroot-2013.05/output/host/lib

/bin/g++ 
CXXFLAGS=-O2 -I/home/CLi/develop/buildroot/buildroot-2013.05/output/host/usr/include

感觉估计就是缺少这些路径和配置，导致编译出错的。

25.还是再去参考：

D:\tmp\tmp_dev_root\cgwin\home\CLi\develop\buildroot\buildroot-2013.05\output\build\host-libtool-2.2.10\config.log

去再次测试一下那个conftest.c，手动模拟编译，看看效果：

去新建：

D:\tmp\tmp_dev_root\cgwin\home\CLi\develop\buildroot\buildroot-2013.05\output\build\host-libtool-2.2.10\conftest.c

内容为config.log输出的内容：

/* confdefs.h */
#define PACKAGE_NAME "libtool"
#define PACKAGE_TARNAME "libtool"
#define PACKAGE_VERSION "2.2.10"
#define PACKAGE_STRING "libtool 2.2.10"
#define PACKAGE_BUGREPORT "[email protected]"
#define PACKAGE_URL ""
#define PACKAGE "libtool"
#define VERSION "2.2.10"
/* end confdefs.h.  */

int
main ()
{

  ;
  return 0;
}

然后再去到对应目录下编译：

CLi@PC-CLI-1 ~/develop/buildroot/buildroot-2013.05
$ cd output/build/host-libtool-2.2.10/

CLi@PC-CLI-1 ~/develop/buildroot/buildroot-2013.05/output/build/host-libtool-2.2.10

CLi@PC-CLI-1 ~/develop/buildroot/buildroot-2013.05/output/build/host-libtool-2.2.10
$

结果很明显，还是正常的，可以编译对应的测试文件的。

26.去看看，此处用的那个：

/bin/gcc

CLi@PC-CLI-1 ~/develop/buildroot/buildroot-2013.05/output/build/host-libtool-2.2.10
$ ls /bin/gcc -lha
-rwxr-xr-x 3 CLi Domänen-Benutzer 507K Jun 16 12:50 /bin/gcc*

貌似也不是软链接，也是ok的。

27.想到了，之前看到某个帖子，给gcc的-v的参数，可以显示详细过程。

所以再去重新编译一次，给-v参数，看看效果：

CLi@PC-CLI-1 ~/develop/buildroot/buildroot-2013.05/output/build/host-libtool-2.2.10

$

此处，可以看到cc1是：

/bin/../lib/gcc/i686-pc-cygwin/4.7.3/cc1.exe

而此处make时出错的是：

/usr/lib/gcc/i686-pc-cygwin/4.7.3/cc1.exe

所以去看看，到底哪个cc1对的：

CLi@PC-CLI-1 ~/develop/buildroot/buildroot-2013.05/output/build/host-libtool-2.2.10
$ ls /lib/gcc/i686-pc-cygwin/4.7.3/cc1.exe -lha
-rwxr-xr-x 1 CLi Domänen-Benutzer 11M Jun 16 12:57 /lib/gcc/i686-pc-cygwin/4.7.3/cc1.exe*

CLi@PC-CLI-1 ~/develop/buildroot/buildroot-2013.05/output/build/host-libtool-2.2.10
$ ls /usr/lib/gcc/i686-pc-cygwin/4.7.3/cc1.exe -lha
-rwxr-xr-x 1 CLi Domänen-Benutzer 11M Jun 16 12:57 /usr/lib/gcc/i686-pc-cygwin/4.7.3/cc1.exe*

貌似两个都是一样的。

另外，对于：

/bin/../lib/gcc/i686-pc-cygwin/4.7.3/cc1.exe

执行时，有个提示：

warning: MPFR header version 3.0.1-p4 differs from library version 3.1.2.

所以，难道是这个版本不兼容，而导致的错误？？

28.那就手动去执行原先：

D:\tmp\tmp_dev_root\cgwin\home\CLi\develop\buildroot\buildroot-2013.05\output\build\host-libtool-2.2.10\config.log

中的配置，即：

./configure --prefix=/home/CLi/develop/buildroot/buildroot-2013.05/output/host/usr --sysconfdir=/home/CLi/develop/buildroot/buildroot-2013.05/output/host/etc --enable-shared --disable-static --disable-gtk-doc --disable-doc --disable-docs --disable-documentation --with-xmlto=no --with-fop=no

去试试：

（先用

rm a.exe conftest.c

去删除我之前弄的那个conftest.c）

再去配置，然后的确是可以的：

所以，此处，可以确定：

估计是当上层的makefile，传递给底层的libtool时，

然后丢失了一些环境，比如PATH等环境变量，所以才导致各种问题的。

但是具体根本原因，在什么时候丢失的这些环境，也还是没搞懂。

29，然后再去对比了：

D:\tmp\tmp_dev_root\cgwin\home\CLi\develop\buildroot\buildroot-2013.05\output\build\host-m4-1.4.16\config.log

和

D:\tmp\tmp_dev_root\cgwin\home\CLi\develop\buildroot\buildroot-2013.05\output\build\host-libtool-2.2.10\config.log

然后看到的结果是：

即，

正确的m4，用的gcc是：result: /home/CLi/develop/buildroot/buildroot-2013.05/output/host/usr/bin/ccache /bin/gcc

错误的libtool，用的gcc是：result: gcc

原因应该是：

D:\tmp\tmp_dev_root\cgwin\home\CLi\develop\buildroot\buildroot-2013.05\output\build\host-m4-1.4.16\config.log

中对应的./configure时给了参数：

CC=/home/CLi/develop/buildroot/buildroot-2013.05/output/host/usr/bin/ccache /bin/gcc

但是为何此处libtool中./configure时没有传入这些参数。还是没搞懂。

不过后来发现，其实上面，最开始的时候，也是出错的时候，也就已经是：

result: /home/CLi/develop/buildroot/buildroot-2013.05/output/host/usr/bin/ccache /bin/gcc

了，所以，貌似此处不是问题原因。

30.再去看看，别的已经编译好的：

host-gmp-5.1.1

host-mpc-1.0.1

host-mpfr-3.1.2

看看其configure时，CC等参数都是否传入进来了。

发现：

D:\tmp\tmp_dev_root\cgwin\home\CLi\develop\buildroot\buildroot-2013.05\output\build\host-gmp-5.1.1\config.log

中也是和从此处类似的：

./configure中，没有额外的CC等参数：

$ ./configure --prefix=/home/CLi/develop/buildroot/buildroot-2013.05/output/host/usr --sysconfdir=/home/CLi/develop/buildroot/buildroot-2013.05/output/host/etc --enable-shared --disable-static --disable-gtk-doc --disable-doc --disable-docs --disable-documentation --with-xmlto=no --with-fop=no

然后检查c编译器版本的结果，当然是yes正常的：

是有切换到对应的路径：

cd /home/CLi/develop/buildroot/buildroot-2013.05/output/build/host-libtool-2.2.10/

然后传入很多参数，然后再去调用配置的

./configure –prefix="/home/CLi/develop/buildroot/buildroot-2013.05/output/host/usr" ……

然后，突然注意到，一个很奇怪的：

LD_LIBRARY_PATH="/home/CLi/develop/buildroot/buildroot-2013.05/output/host/usr/lib:"

即，LD_LIBRARY_PATH的值，最后竟然是一个冒号，

感觉此冒号，是多余的，应该没有才对。

然后就去找，是哪里，弄出了此多余的冒号。

31.不过，对于之前的：

>>> host-mpfr 3.1.2 Configuring

其中也有同样的冒号的：

LD_LIBRARY_PATH="/home/CLi/develop/buildroot/buildroot-2013.05/output/host/usr/lib:"

32.后来看之前的输出的log，看到一个提示：

make[5]: Entering directory `/home/CLi/develop/buildroot/buildroot-2013.05/output/build/host-gmp-5.1.1'

所以，抽空可以去：

make clean

然后再去

make check

一下，然后再

make

或许会有新发现。

不过，发现，buildroot中，貌似就没有

make check

所以，也就不用去试了。

33.再去libtool目录下，去删除刚才的配置：

CLi@PC-CLI-1 ~/develop/buildroot/buildroot-2013.05
$ cd output/build/host-libtool-2.2.10/

CLi@PC-CLI-1 ~/develop/buildroot/buildroot-2013.05/output/build/host-libtool-2.2.10
$ make help

CLi@PC-CLI-1 ~/develop/buildroot/buildroot-2013.05/output/build/host-libtool-2.2.10
$ make distclean

make: *** [distclean-recursive] Error 1

CLi@PC-CLI-1 ~/develop/buildroot/buildroot-2013.05/output/build/host-libtool-2.2.10
$

结果没发删除。

算了，还是把整个host-libtool-2.2.10 文件夹删除掉，然后去buildroot根目录make吧：

CLi@PC-CLI-1 ~/develop/buildroot/buildroot-2013.05
$ rm -rf output/build/host-libtool-2.2.10/

CLi@PC-CLI-1 ~/develop/buildroot/buildroot-2013.05
$ make

结果是：

错误依旧：

40。测试到现在，感觉还是由于此处

libtool的configure文件中，调用的时候，没有传入对应的CC等参数。

然后突然看到个奇怪的现象：

对于三个不用的config.log，对应的头部信息中，所用的libtool都不同：

D:\tmp\tmp_dev_root\cgwin\home\CLi\develop\buildroot\buildroot-2013.05\output\build\host-m4-1.4.16\config.log

中是：

It was created by GNU M4 configure 1.4.16, which was
generated by GNU Autoconf 2.69.  Invocation command line was

而

D:\tmp\tmp_dev_root\cgwin\home\CLi\develop\buildroot\buildroot-2013.05\output\build\host-gmp-5.1.1\config.log

是：

It was created by GNU MP configure 5.1.1, which was
generated by GNU Autoconf 2.69.  Invocation command line was

而此处出错的：

D:\tmp\tmp_dev_root\cgwin\home\CLi\develop\buildroot\buildroot-2013.05\output\build\host-libtool-2.2.10\config.log

是：

It was created by libtool configure 2.2.10, which was
generated by GNU Autoconf 2.65.  Invocation command line was

即，此处的用的是autoconf 2.65，而不是正常的m4和gmp用的autoconf 2.69

41.看到一个buildroot的patch：

http://git.buildroot.net/buildroot/plain/package/autoconf/autoconf-dont-add-dirty-to-version.patch

也提到这两个版本，但是此问题没关系。

然后看到：

http://git.buildroot.net/buildroot/plain/package/autoconf/autoconf.mk

写的是

AUTOCONF_VERSION = 2.69

去本地的buildroot对应位置看看：

D:\tmp\tmp_dev_root\cgwin\home\CLi\develop\buildroot\buildroot-2013.05\package\autoconf\autoconf.mk

看到的是：

AUTOCONF_VERSION = 2.68

另外也看了看：

D:\tmp\tmp_dev_root\cgwin\home\CLi\develop\buildroot\buildroot-2013.05\package\libtool\Config.in

和：

D:\tmp\tmp_dev_root\cgwin\home\CLi\develop\buildroot\buildroot-2013.05\package\libtool\libtool.mk

没感觉有什么特殊的。

42.所以去重新配置看看，能否把autoconf，从此处的2.68，换成最新的（buildroot网站上面的那个）2.69

结果没找到配置。

算了，手动修改：

D:\tmp\tmp_dev_root\cgwin\home\CLi\develop\buildroot\buildroot-2013.05\package\autoconf\autoconf.mk

中的：

AUTOCONF_VERSION = 2.68

为：

#AUTOCONF_VERSION = 2.68
AUTOCONF_VERSION = 2.69

然后再去make试试：

很明显，是那个：

D:\tmp\tmp_dev_root\cgwin\home\CLi\develop\buildroot\buildroot-2013.05\package\autoconf\autoconf-dont-add-dirty-to-version.patch

打补丁失败，然后看到其中内容是：

--- autoconf-2.65.orig/build-aux/git-version-gen
+++ autoconf-2.65/build-aux/git-version-gen

即，针对的是2.65的，所以应该对于此处的2.69没影响，所以去去掉：

从：

autoconf-dont-add-dirty-to-version.patch

改名为：

__autoconf-dont-add-dirty-to-version.patch

再去make编译：

CLi@PC-CLI-1 ~/develop/buildroot/buildroot-2013.05
$ make

算了，暂时改为别的名字吧：

43.再去看：

D:\tmp\tmp_dev_root\cgwin\home\CLi\develop\buildroot\buildroot-2013.05\output\build\host-libtool-2.2.10\config.log

结果竟然还是2.65的：

generated by GNU Autoconf 2.65.  Invocation command line was

然后看到当前cygwin中，是2.69的：

44.再去看看：

依旧是2.65：

看来，不是此处buildroot中的autoconf所决定的。

然后发现，好像是其自己下面对应的文件决定的：

D:\tmp\tmp_dev_root\cgwin\home\CLi\develop\buildroot\buildroot-2013.05\output\build\host-libtool-2.2.10\aclocal.m4

中的：

m4_if(m4_defn([AC_AUTOCONF_VERSION]), [2.65],,
[m4_warning([this file was generated for autoconf 2.65.

D:\tmp\tmp_dev_root\cgwin\home\CLi\develop\buildroot\buildroot-2013.05\output\build\host-libtool-2.2.10\configure

中的：

#! /bin/sh
# Guess values for system-dependent variables and create Makefiles.
# Generated by GNU Autoconf 2.65 for libtool 2.2.10.

所以，得抽空再去研究。

45.再去手动试试：

46.看到这里：

compile error – conftest.c:14625: must be after ` <at> defmac’ to use ` <at> defmacx’

即：

compile error – conftest.c:14625: must be after address@hidden’ to use a

也提到了类似的，2.65,2.69的autoconf的问题。但是和我此处错误不同。

然后去看看其提到的

autoconf-2.65/doc/autoconf.texi

但是此处没有源码。没法查看。

47.此处再尝试：

D:\tmp\tmp_dev_root\cgwin\home\CLi\develop\buildroot\buildroot-2013.05\package\autoconf\autoconf.mk

改为：

#AUTOCONF_VERSION = 2.68
#AUTOCONF_VERSION = 2.69
AUTOCONF_VERSION = 2.65

然后把之前的patch文件：

autoconf-dont-add-dirty-to-version.patch

内容为：

autoconf: don't append -dirty to version

Don't append -dirty to autoconf version number if the buildroot git tree
has uncommited changes.

This script is meant for the autoconf developers, but it also activates
if you build autoconf in a subdirectory of a git tree (E.G. like how it's
commonly done in buildroot).

The affect is that autoconf gets built as being version 2.65-dirty, which
breaks programs (like Python) which explicitly checks for autoconf-2.65.

然后再去删除旧的libtool：

$ rm output/build/host-libtool-2.2.10/ -rf

然后再去make试试：

所以，去试试给此处的libtool 2.2.10也打上此补丁试试：

感觉此处对于：

D:\tmp\tmp_dev_root\cgwin\home\CLi\develop\buildroot\buildroot-2013.05\output\build\host-libtool-2.2.10\libltdl\m4\libtool.m4

的补丁都没生效啊。

【总结】

暂时不知道具体什么原因导致的此处编译有问题。

【后记 2013-09-10】

1。后来继续折腾：

【已解决】再次研究：Cygwin下编译Buildroot时在编译libtool-2.2.10时出错：/usr/lib/gcc/i686-pc- cygwin/4.7.3/cc1.exe: error while loading shared libraries: ?: cannot open shared object file: No such file or directory

还是没搞定。

2.再次继续折腾，终于搞定了。

关于问题的解决办法，详见该贴的最后：

【记录】第三次去研究：Cygwin下编译Buildroot时在编译libtool-2.2.10时出错：/usr/lib/gcc/i686-pc- cygwin/4.7.3/cc1.exe: error while loading shared libraries: ?: cannot open shared object file: No such file or directory
