下载glibc2.15源码 http://ftp.gnu.org/gnu/glibc

解压后目录下执行 ./configure --prefix=/usr/local/glib --enable-static --disable-shared CFLAGS=\"-static\"

编译出错

configure: error: you must configure in a separate build directory

跳出新建目录 glibc-2.15-build 在该目录下以绝对路径执行

出错

configure: error:

*** LD_LIBRARY_PATH shouldn\'t contain the current directory when

*** building glibc. Please change the environment variable

*** and run configure again.

暂时删除 LD_LIBRARY_PATH 之后再添加

linux@ubuntu:~/songhui/software/glibc-2.15-bulid$ echo $LD_LIBRARY_PATH

:/home/linux/dynamiclib/libsum.so

linux@ubuntu:~/songhui/software/glibc-2.15-bulid$ LD_LIBRARY_PATH=

之后 执行

vim /etc/profile export LD_LIBRARY_PATH = $LD_LIBRARY_PATH:/home/linux/dynamiclib/libsum.so //wq 保存退出，使之生效 source /etc/profile

出错

configure: error: er with -z relro support required

安装

sudo apt-get install gawk

出错

/home/linux/songhui/software/glibc-2.15-bulid/config.h:3:3: error: #error \"glibc cannot be compiled without optimization\"

重新configure 在CFLAGS中添加 CFLAGS=\"-static -g -O2 -march=i686\"

出错

Google了一下，大概是gcc3.4.2及以前的版本对奔腾3及以后的CPU定义了#define __i686 1，但之后的gcc使用__x86并修复了(我的是4.6.3)(而且TMD 2.16的glibc也对应修复了，我需要的是2.15)

修改对应文件中的__i686 -> __x86

无效

找到外国友人一段话

The problem is caused by your GCC defining __i686. You can confirm that in fact it does that with this command:

gcc -dD -E -xc /dev/null | grep __i686

If this command produces output, then that\'s the problem. To fix it, use:

configure --prefix=/usr CC=\'gcc -U__i686\'

or build a newer version of glibc.

修改

/home/linux/songhui/software/glibc-2.15/configure --prefix=/usr/local/glib --enable-static --disable-shared CFLAGS=\"-static -g -O2 -march=i686\"

为

/home/linux/songhui/software/glibc-2.15/configure --prefix=/usr/local/glib CC=“gcc -U__i686” --enable-static --disable-shared CFLAGS=\"-static -g -O2 -march=i686\"

重新编译

出错

(错误没有截取，但是出错的地方一样)

修改 去掉 --disable-shared

/home/linux/songhui/software/glibc-2.15/configure --prefix=/usr/local/glib CC=\"gcc -U__i686\" --enable-static CFLAGS=\"-static -g -O2 -U_FORTIFY_SOURCE -fno-stack-protector -march=i686\"

make OK，

sudo make install OK

（每次出错后，基本都是全部删除重来configure）
