请问各位高人一个sed命令！

longkz

sed -i \
's|libs -o|libs -L/usr/lib-Wl,-dynamic-linker=/lib/ld-linux.so.2 -o|' \
        scripts/test-installation.pl
如题，谢谢！

longkz

在lfs6.2的6.9小节：
root:/sources/glibc-2.3.6# sed -i \
> 's|libs -o|libs -L/usr/lib-W1,-dynamic-linker=/lib/ld-linux.so.2 \
> -o| '   scripts/test-installation.pl
root:/sources/glibc-2.3.6#
  执行之后，在test-installation.pl之中只有以下最有可能是：
open GCC, "$CC /tmp/test-prg$$.c $link_libs -L/usr/lib -W1,-dynamic-linker=/lib/ld-linux.so.2
-o /tmp/test-prg$$ 2>&1 |"
  or die ("Couldn't execute $CC!");
  哪位大侠能解释一下是怎么回事阿？

果然出错了，make install 后：
CC="gcc" /usr/bin/perl scripts/test-installation.pl /sources/glibc-build/
cc1: error: unrecognized command line option "-W1,-dynamic-linker=/lib/ld-linux.so.2"
sh: line 1: -o: command not found
Execution of gcc failed!
The script has found some problems with your installation!
Please read the FAQ and the README file and check the following:
- Did you change the gcc specs file (necessary after upgrading from
  Linux libc5)?
- Are there any symbolic links of the form libXXX.so to old libraries?  Links like libm.so -> libm.so.5 (where libm.so.5 is an old library) are wrong,
  libm.so should point to the newly installed glibc file - and there should be
  only one such link (check e.g. /lib and /usr/lib)
You should restart this script from your build directory after you've
fixed all problems!
Btw. the script doesn't work if you're installing GNU libc not as yourprimary library!
make[1]: *** [install] Error 1
make[1]: Leaving directory `/sources/glibc-2.3.6'
make: *** [install] Error 2

怎么论坛人这么少阿？？

是-Wl(小写的L，不是1)，开始我想当然的把它当作了gcc的警告等级，也在这里搞了半天

longkz

那现在怎么办那 ？

waiting4you

再用sed修改一下

sed -i 's|-W1,|-Wl,|' scripts/test-installation.pl

第一个是数字1,第二个是小写的L,它的作用就是把你写错了的-W1,改成正确的-Wl.
然后直接make install就可以了,这个文件只影响安装,不需要重编译了.

多谢，可惜我不会sed，我是用vi改的！
