【问题】
折腾：
期间，在Installing C library headers & start files期间，去配置eglibc，结果算是基本解决了：
configure: error: support for the tls_model attribute is required
的问题，但是看到有警告：

| checking add-on ports for preconfigure fragments… aarch64 alpha am33 arm arm/preconfigure: Did not find ARM architecture type; using default |
【解决过程】
1.去搜了搜，看到：
GNU C Library master sources branch roland/arm-preconfigure created. glibc-2.17-370-g0559cee
中有：
diff --git a/ports/sysdeps/arm/preconfigure b/ports/sysdeps/arm/preconfigure index 6d61b14..0042aaf 100644 --- a/ports/sysdeps/arm/preconfigure +++ b/ports/sysdeps/arm/preconfigure @@ -1,53 +1,58 @@ +# This file is generated from configure.in by Autoconf.

+ ;;
+ esac+ machine=arm + AC_MSG_WARN([arm/preconfigure: Did not find ARM architecture type; using default]) + ;; + esac + + machine=arm/$machine +esac |
很明显，其中是对于libc-ports新加的配置内容。
2.然后注意到，此处应该是：
eglibc中的（用到的？）libc，其附属东西：
ports
部分，出现这个问题的。
然后参考上面的patch，去找到了：
E:\dev_install_root\cygwin\home\develop\crosstool-ng\crosstool-ng-1.18.0_build\.build\src\eglibc-2_17\ports\sysdeps\arm\preconfigure
中，的确有这部分的配置内容：
case "$machine" in
arm*)
base_machine=arm
case $config_os in
linux-gnueabi*)
# Lets ask the compiler which ARM family we've got
# Unfortunately it doesn't define any flags for implementations
# that you might pass to -mcpu or -mtune
# Note if you add patterns here you must ensure that
# an appropriate directory exists in sysdeps/arm
archcppflag=`echo "" |
$CC $CFLAGS $CPPFLAGS -E -dM - |
grep __ARM_ARCH |
sed -e 's/^#define //' -e 's/ .*//'`
case x$archcppflag in
x__ARM_ARCH_[89]*__)
machine=armv7
echo "Found compiler is configured for something newer than v7 - using v7"
;;
x__ARM_ARCH_7A__)
machine=armv7
echo "Found compiler is configured for $machine"
;;
x__ARM_ARCH_6T2__)
machine=armv6t2
echo "Found compiler is configured for $machine"
;;
*)
machine=arm
echo 2>&1 "arm/preconfigure: Did not find ARM architecture type; using default"
;;
esac
machine=arm/$machine
if [ "${CFLAGS+set}" != "set" ]; then
CFLAGS="-g -O2"
fi
CFLAGS="$CFLAGS -fno-unwind-tables"
;;
linux*)
echo "Old ABI no longer supported" 2>&1
exit 1
;;
esac
;;
esac但是，还是不知道如何避免此问题。
不知道，想要添加armv4的话，如何添加。
还是要换用别的，更新的那个版本的eglibc？
还是换用别的版本的libc？
2.对于此问题，去搜，结果竟然发现，自己的帖子：
中，就已经出现了此警告：
|
所以是：
之前mcpu和march冲突，就已经出现此问题
但是上述帖子中，没解决掉此问题。
此处还是出现了此警告，但是却是由于内部配置文件中本身就不支持armv4t（只支持armv7，armv6t2）
结果还是无法解决此问题。
3.看到该贴的回复：
Re: [ARM] architecture specific subdirectories & optimised memchr [V3]
的解释：
The usual way to do this sort of thing is by using --with-cpu at configure time. |
虽然没完全看懂，但是觉得说的有理，应该是通过配置得到的，而不是此处弄个preconfigure去搞得armv4t都不支持。。
【总结】
算了，还是没找到解决办法，暂且还是凑合用吧。
继续去编译。
