编译qt4时用到mysql-5.1.53，编译出错：

1 glibc和eglibc都编译出错！
2 uClibc编译通过！
3 openwrt-dreambox情况和openwrt-for-embedded情况一样！

在build_dir/toolchain-arm_v7-a_gcc-4.3.3+cs_eglibc-2.8_eabi下：
grep -r "__libc_csu_fini" ./
查找相关信息。

1. 下面是有关于__libc_csu_fini的定义，它是个全局变量？！：
./eglibc-2.8-r8587/libc/sysdeps/sh/elf/start.S: .long   __libc_csu_fini

2. arm中有使用：
./eglibc-2.8-r8587/libc/ports/sysdeps/arm/elf/start.S:  ldr ip, =__libc_csu_fini
./eglibc-2.8-r8587/ports/sysdeps/arm/elf/start.S:   ldr ip, =__libc_csu_fini

3. 关于__libc_csu_fini的说明
./eglibc-2.8-r8587/libc/ChangeLog.14:   and __libc_csu_fini in place of _fini.
./eglibc-2.8-r8587/libc/ChangeLog.16:   * csu/elf-init.c (__libc_csu_fini): 
Pretty printing.
./eglibc-2.8-r8587/libc/ChangeLog.16:   * csu/elf-init.c (__libc_csu_fini): 
Enable if LIBC_NONSHARED
./eglibc-2.8-r8587/libc/ChangeLog.16:   * csu/elf-init.c (__libc_csu_fini): Don't 
do anything here.

编译sdlpal仙剑游戏时用到了__libc_csu_fini：（build_dir/target-xx目�

详见：http://www.linuxquestions.org/questions/linux-general-1/undefined-refer
ence-to-%60__libc_csu_fini-849247/
TOOLCHAINDIR/usr/lib/crt1.o中的__libc_csu_fini，__libc_csu_init函数没有��
�义（是引用外部函数的）
使用objdump -x crt1.o命令可以查看的到：
00000000 l       .text  00000000 $a
00000000 l       .data  00000000 $d

00000000         *UND*  00000000 __libc_csu_fini
00000000         *UND*  00000000 abort

00000000 g       .data  00000000 __data_start

RELOCATION RECORDS FOR [.text]:

00000024 UNKNOWN           __libc_start_main
00000028 UNKNOWN           abort
0000002c UNKNOWN           __libc_csu_fini
00000030 UNKNOWN           main
00000034 UNKNOWN           __libc_csu_init

实际上他们最终是要使用应该定义在TOOLCHAINDIR/usr/lib/libc.so(该
文件定义了这两个函数)，
而实际上eglibc/glibc中的TOOLCHAINDIR/usr/lib/libc.so是一个文本文件�
��
cat TOOLCHAINDIR/usr/lib/libc.so

/* GNU ld script
   Use the shared library, but some functions are only in
   the static library, so try that secondarily.  */
OUTPUT_FORMAT(elf32-littlearm)
GROUP ( libc.so.6 libc_nonshared.a  AS_NEEDED ( ld-linux.so.3 ) )

而uClibc使用的是链接到../../lib/libc.so，而又再链接到../../lib/li
buClibc-0.9.30.1.so，所以在uClibc中会成功编译！！！！！！！！�
��（eglibc/glibc的../../lib/libc.so仍为内容相同的文本文件！！）

实际上下面两个静态库定义了这两个函数：（从libc.so文本文�
��中也可以看得出！）
TOOLCHAINDIR/usr/lib/libc_nonshared.a
TOOLCHAINDIR/usr/lib/libc.a

所以，解决办法：
1 使用-L$TOOLCHAINDIR/usr/lib/libc.a -L$TOOLCHAINDIR/usr/lib/libc_nonshared.a
2 把libc_nonshared.a，libc.a，链接出.so的软链接？

1 使用判断语句，是否是真的二进制库？
如果是，不动，如果不是则链接！

2 或者判断使用的是uClibc还是eglibc/glibc来解决这个问题

1 之后又出现ld：cannot found 
uClibc++.so（因为它依赖uClibc++，先make下把uClibc++编译了就行）�
��
2 libc.so这个脚本是用来链接到libc.so.6 libc_nonshared.a！

我擦，网友在尝试各种方法后，该网友尝试加了 
-lc(指定使用libc.so或者libc.a)，编译成功！！！！！！！！！��
�！
详见：http://sourceware.org/ml/libc-help/2009-12/msg00017.html

我尝试了下，可以通过编译！！！！！！！！！
不知运行是不是也可以？理论上应该可以（虽说不是使用的��
�态libc.so，是使用的静态libc.a）
