【问题】
折腾：
期间，已经解决了该问题了，但是接着又出错：

即：

【折腾过程】
1.此问题，刚一开始，以为和之前的：
是一样的，所以去手动修改：
E:\dev_install_root\cygwin\home\develop\crosstool-ng\crosstool-ng-1.18.0_build\.build\src\eglibc-2_15\sunrpc\rpc\types.h
为：
（注意：之前的解决办法中，修改错了，把#endif放到最后了，实际上应该是放到APPLE后面即可）
#ifndef makedev /* ie, we haven't already included it */ #include <sys/types.h> #endif //#ifndef __u_char_defined /* * OS X and Cygwin already has these <sys/types.h> */ #ifndef __CYGWIN__ //add for check for __CYGWIN__ #ifndef __APPLE__ # ifndef __u_char_defined typedef __u_char u_char; typedef __u_short u_short; typedef __u_int u_int; typedef __u_long u_long; typedef __quad_t quad_t; typedef __u_quad_t u_quad_t; typedef __fsid_t fsid_t; //# define __u_char_defined //#endif # define __u_char_defined # endif #ifndef __daddr_t_defined typedef __daddr_t daddr_t; typedef __caddr_t caddr_t; //# define __daddr_t_defined //#endif # define __daddr_t_defined # endif #endif /* __APPLE__ */ #endif /* __CYGWIN__ */ #include <sys/time.h> #include <sys/param.h>
然后继续用exit 2继续编译试试，结果错误依旧：
Re-trying last command.

很明显，没有解决此问题，还是同样错误。
没有解决此处问题。
2.再次去试试：
把：
E:\dev_install_root\cygwin\home\develop\crosstool-ng\crosstool-ng-1.18.0_build\.build\src\eglibc-2_15\sunrpc\rpc\types.h
改为：
//#ifndef __u_char_defined /* * OS X and Cygwin already has these <sys/types.h> */ #ifndef __CYGWIN__ //add for check for __CYGWIN__ #ifndef __APPLE__ # ifndef __u_char_defined typedef __u_char u_char; typedef __u_short u_short; typedef __u_int u_int; typedef __u_long u_long; typedef __quad_t quad_t; typedef __u_quad_t u_quad_t; typedef __fsid_t fsid_t; //# define __u_char_defined //#endif # define __u_char_defined # endif #ifndef __daddr_t_defined typedef __daddr_t daddr_t; typedef __caddr_t caddr_t; //# define __daddr_t_defined //#endif # define __daddr_t_defined # endif #endif /* __APPLE__ */ #include <sys/time.h> #include <sys/param.h> #include <netinet/in.h> #ifndef INADDR_LOOPBACK #define INADDR_LOOPBACK (u_long)0x7F000001 #endif #ifndef MAXHOSTNAMELEN #define MAXHOSTNAMELEN 64 #endif #endif /* rpc/types.h */ #endif /* __CYGWIN__ */
再去exit 2试试结果：
结果错误还是依旧。
3.此刻，才注意到，此处的问题，是在：
Installing C library的Building C library出现的：
| rpc/types.h:73:18: error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ before ‘u_char’ |
和之前：
的，在：
Installing C library headers & start files
的
Installing C library headers
中出现的：
| rpc/types.h:73:18: error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ before ‘u_char’ |
错误现象是一样，但是出现的阶段是不一样的。
即，还不是同一个错误的。
4.此处，怀疑是：
gcc去编译：rpc_parse.c去生成：
.build/arm-arm920t-linux-gnueabi/build/build-libc-final/sunrpc/rpc_parse.o
时，此处只去修改rpc_parse.c内部所包含的rpc/types.h，但是gcc是找不到的。
因为不是makefile中所指定了：
rpc_parse.c
所依赖
rpc/types.h
所以，还是用的是就的rpc_parse.c
但是突然发现，此处，还是要去include最新的
rpc/types.h
的，所以，如果修改后，应该可以找到的。
5.此处，故意先把：
E:\dev_install_root\cygwin\home\develop\crosstool-ng\crosstool-ng-1.18.0_build\.build\src\eglibc-2_15\sunrpc\rpc\types.h
改错，比如：
//#ifndef __u_char_defined /* * OS X and Cygwin already has these <sys/types.h> */ # if nd ef __CYGWIN__ //add for check for __CYGWIN__
看看是否会报此76行出错。
结果的确报错了：
[ERROR] ../sunrpc/rpc/types.h:76:9: error: missing binary operator before token "ef"
说明此处的确是调用的此：
E:\dev_install_root\cygwin\home\develop\crosstool-ng\crosstool-ng-1.18.0_build\.build\src\eglibc-2_15\sunrpc\rpc\types.h
6.还是改为：
//#ifndef __u_char_defined /* * OS X and Cygwin already has these <sys/types.h> */ #ifndef __CYGWIN__ //add for check for __CYGWIN__ #ifndef __APPLE__ # ifndef __u_char_defined typedef __u_char u_char; typedef __u_short u_short; typedef __u_int u_int; typedef __u_long u_long; typedef __quad_t quad_t; typedef __u_quad_t u_quad_t; typedef __fsid_t fsid_t; //# define __u_char_defined //#endif # define __u_char_defined # endif #ifndef __daddr_t_defined typedef __daddr_t daddr_t; typedef __caddr_t caddr_t; //# define __daddr_t_defined //#endif # define __daddr_t_defined # endif #endif /* __APPLE__ */ #endif /* __CYGWIN__ */ #include <sys/time.h> #include <sys/param.h> #include <netinet/in.h> #ifndef INADDR_LOOPBACK #define INADDR_LOOPBACK (u_long)0x7F000001 #endif #ifndef MAXHOSTNAMELEN #define MAXHOSTNAMELEN 64 #endif #endif /* rpc/types.h */
看看结果：
结果错误依旧。
7.去搜：
__u_char_defined
而找到：
（1）
http://enduser.subsignal.org/~trondah/tree/toolchain/eglibc/patches/2.15/100-fix_cross_rpcgen.patch
其中有：
--- a/libc/sunrpc/rpc/types.h +++ b/libc/sunrpc/rpc/types.h @@ -70,18 +70,23 @@ typedef unsigned long rpcport_t; #endif #ifndef __u_char_defined -typedef __u_char u_char; -typedef __u_short u_short; -typedef __u_int u_int; -typedef __u_long u_long; -typedef __quad_t quad_t; -typedef __u_quad_t u_quad_t; -typedef __fsid_t fsid_t; +typedef unsigned char u_char; +typedef unsigned short u_short; +typedef unsigned int u_int; +typedef unsigned long u_long; +#if __WORDSIZE == 64 +typedef long int quad_t; +typedef unsigned long int u_quad_t; +#elif defined __GLIBC_HAVE_LONG_LONG +typedef long long int quad_t; +typedef unsigned long long int u_quad_t; +#endif +typedef u_quad_t fsid_t; # define __u_char_defined #endif -#ifndef __daddr_t_defined -typedef __daddr_t daddr_t; -typedef __caddr_t caddr_t; +#if !defined(__daddr_t_defined) && defined(linux) +typedef long int daddr_t; +typedef char *caddr_t; # define __daddr_t_defined #endif
所以，对照着，先去看看，我此处是否有此patch：
看到：
E:\dev_install_root\cygwin\home\develop\crosstool-ng\crosstool-ng-1.18.0\patches\eglibc\2_15
下面只有：
100-Remove-test-for-__builtin_expect.patch
所以是没有改patch的。
（2）另外，找到很多eglibc的mailinglist，结果却都打不开：
http://www.eglibc.org/archives/patches/msg01116.html
http://www.eglibc.org/archives/patches/msg01118.html
http://www.eglibc.org/archives/patches/msg01117.html
所以，打算把上述的内容手动合并到此处。
不过又从：
http://enduser.subsignal.org/~trondah/tree/toolchain/eglibc/patches/2.15/
发现，原来不止一个patch：
001-fix_autoconf_macro.patch 07-Jun-2012 15:02 1539 050-all_glibc-2.14-leak-revert-crash.patch 26-Jun-2013 01:22 3826 100-fix_cross_rpcgen.patch 07-Jun-2012 15:02 2090 110-fix_cross_zic.patch 07-Jun-2012 15:02 708 120-use_host_cflags.patch 31-Oct-2012 08:26 885 200-add-dl-search-paths.patch 07-Jun-2012 15:02 367 |
注：
另外也发现，eglibc的其他版本的patch的：
http://enduser.subsignal.org/~trondah/tree/toolchain/eglibc/patches/2.16/
http://enduser.subsignal.org/~trondah/tree/toolchain/eglibc/patches/2.17/
8.所以，干脆，把上面一堆的patch，都下载下来，然后拷贝到：
E:\dev_install_root\cygwin\home\develop\crosstool-ng\crosstool-ng-1.18.0\patches\eglibc\2_15
中，这样就有了：
001-fix_autoconf_macro.patch
050-all_glibc-2.14-leak-revert-crash.patch
100-fix_cross_rpcgen.patch
100-Remove-test-for-__builtin_expect.patch
110-fix_cross_zic.patch
120-use_host_cflags.patch
200-add-dl-search-paths.patch
然后再重新ct-ng clean：
Administrator@PC-20130611GART /home/develop/crosstool-ng/crosstool-ng-1.18.0_build $ ct-ng clean CLEAN config CLEAN config.gen CLEAN log
后，重新编译，看看是否可以彻底的解决此问题。
正在编译。
但是貌似刚才忘了删除：
E:\dev_install_root\cygwin\home\develop\crosstool-ng\crosstool-ng-1.18.0_build\.build\src\.eglibc-2_15.extracted
和
E:\dev_install_root\cygwin\home\develop\crosstool-ng\crosstool-ng-1.18.0_build\.build\src\.eglibc-2_15.patched
所以，估计到时候还是会出错，所以：
如果出错，则去：
删除：
E:\dev_install_root\cygwin\home\develop\crosstool-ng\crosstool-ng-1.18.0_build\.build\src\eglibc-2_15
再删除
E:\dev_install_root\cygwin\home\develop\crosstool-ng\crosstool-ng-1.18.0_build\.build\src\.eglibc-2_15.extracted
和
E:\dev_install_root\cygwin\home\develop\crosstool-ng\crosstool-ng-1.18.0_build\.build\src\.eglibc-2_15.patched
然后exit 2，重新编译，试试，
然后，看了对应的log是：

感觉好像是解决了此问题了。
但是还是要去确认一下：
E:\dev_install_root\cygwin\home\develop\crosstool-ng\crosstool-ng-1.18.0_build\.build\src\eglibc-2_15\sunrpc\rpc\types.h
中的内容，结果却是，的确就是之前手动修改的：
//#ifndef __u_char_defined /* * OS X and Cygwin already has these <sys/types.h> */ #ifndef __CYGWIN__ //add for check for __CYGWIN__ #ifndef __APPLE__ # ifndef __u_char_defined typedef __u_char u_char; typedef __u_short u_short; typedef __u_int u_int; typedef __u_long u_long; typedef __quad_t quad_t; typedef __u_quad_t u_quad_t; typedef __fsid_t fsid_t; //# define __u_char_defined //#endif # define __u_char_defined # endif #ifndef __daddr_t_defined typedef __daddr_t daddr_t; typedef __caddr_t caddr_t; //# define __daddr_t_defined //#endif # define __daddr_t_defined # endif #endif /* __APPLE__ */ #endif /* __CYGWIN__ */
而不是上面的打了补丁：
E:\dev_install_root\cygwin\home\develop\crosstool-ng\crosstool-ng-1.18.0\patches\eglibc\2_15\100-fix_cross_rpcgen.patch
后的内容。
感觉是：
还是重新编译，使得此处的：
E:\dev_install_root\cygwin\home\develop\crosstool-ng\crosstool-ng-1.18.0_build\.build\src\eglibc-2_15\sunrpc\rpc\types.h
真正的生效了。
而之前的，貌似没有生效。
或者是对应的rpc_parse.o
或者是其他相关的文件，是用未修改
E:\dev_install_root\cygwin\home\develop\crosstool-ng\crosstool-ng-1.18.0_build\.build\src\eglibc-2_15\sunrpc\rpc\types.h
之前的版本，编译出来的，所以出错。
【总结】
此处，在Installing C library的Building C library出现：
rpc/types.h:73:18: error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ before ‘u_char’
的错误，的原因是：
E:\dev_install_root\cygwin\home\develop\crosstool-ng\crosstool-ng-1.18.0_build\.build\src\eglibc-2_15\sunrpc\rpc\types.h
是和之前：
遇到类似的，有问题的。
然后经过在crosstool-ng提供的active shell中用exit 2重新编译，结果还是不行的。
最终是
ct-ng clean
后，再重新编译，结果才可以的。
其中：
（1）E:\dev_install_root\cygwin\home\develop\crosstool-ng\crosstool-ng-1.18.0_build\.build\src\eglibc-2_15\sunrpc\rpc\types.h
是之前手动修改过的，为：
//#ifndef __u_char_defined /* * OS X and Cygwin already has these <sys/types.h> */ #ifndef __CYGWIN__ //add for check for __CYGWIN__ #ifndef __APPLE__ # ifndef __u_char_defined typedef __u_char u_char; typedef __u_short u_short; typedef __u_int u_int; typedef __u_long u_long; typedef __quad_t quad_t; typedef __u_quad_t u_quad_t; typedef __fsid_t fsid_t; //# define __u_char_defined //#endif # define __u_char_defined # endif #ifndef __daddr_t_defined typedef __daddr_t daddr_t; typedef __caddr_t caddr_t; //# define __daddr_t_defined //#endif # define __daddr_t_defined # endif #endif /* __APPLE__ */ #endif /* __CYGWIN__ */
（2）没有去删除：
文件夹：E:\dev_install_root\cygwin\home\develop\crosstool-ng\crosstool-ng-1.18.0_build\.build\src\eglibc-2_15
两个文件：
E:\dev_install_root\cygwin\home\develop\crosstool-ng\crosstool-ng-1.18.0_build\.build\src\.eglibc-2_15.extracted
E:\dev_install_root\cygwin\home\develop\crosstool-ng\crosstool-ng-1.18.0_build\.build\src\.eglibc-2_15.patched
无论如何，至少此处的确是可以正常编译下去了，虽然又出现其他错误：
