centos 編譯安裝glibc-2.12.1

在使用daikon建議的kvasir工具時，碰到一些問題，首先是由於該工具比較老，只支持內核最高爲2.6的linux系統，其次須要的glibc版本最高爲2.11（實在忍不住想吐個槽）。最後我把linux系統換成了fedora14，用yum安裝的glibc版本是2.13，只好手動安裝2.11版本的glibc。

• tar -xvf glibc-2.5.tar.gz

• cd glibc-2.5 

• mkdir glibc-2.11-build 

• cd glibc-2.11-build/ 

• export CFLAGS="-g -O2 -march=i686"

• ../configure --prefix=/repo/root/TEST_PACKAGES/robot/PACKAGES/glibc-2.5 --with-headers=/usr/include

• make 

• make install

注意：

1.   在目錄usr/src/glibc-2.11執行configure命令時不能執行，需在外部文件夾glibc-2.11-build 執行

2.   加上優化開關，export CFLAGS="-g -O2 -march=i686"，不然會出現錯誤，此處的i686請參照本身的機器

3.    當有以下錯誤時：

checking whether ranlib is necessary... no
checking LD_LIBRARY_PATH variable... contains current directory
configure: error:
*** LD_LIBRARY_PATH shouldn't contain the current directory when
*** building glibc. Please change the environment variable
*** and run configure again.
解決辦法：查看LD_LIBRARY_PATH  echo $LD_LIBRARY_PATH，個人打印的是/usr/lib/qt44/lib:

configure裏說：LD_LIBRARY_PATH不能以終結符做爲開始和最後一個字符，不能有2個終結符連在一塊兒，因此修改下LD_LIBRARY_PATH便可，export LD_LIBRARY_PATH=/usr/lib/qt44/lib

4.   當有以下錯誤時：

configure: error: gcc must provide the  header

解決辦法：get the cpuid.h file from official GCC respositories> (http://gcc.gnu.org/viewcvs/tags/gcc_4_4_2_release/gcc/config/i386/cpuid.h?view=co)> and put it into /usr/include（上面指定的--with-headers）

5.   當有以下錯誤時：

修改兩個文件：

* sysdeps/unix/sysv/linux/i386/sysdep.h: Re-define __i686.
       * nptl/sysdeps/pthread/pt-initfini.c: Ditto.

5.   當以上問題都解決時，make  make install吧，因爲東西比較多，須要些時間，大概半小時左右。
