提示如下：
| Code: | checking whether the C compiler (gcc -O2 -mcpu=i686 -pipe -mieee ) works... no
configure: error: installation or configuration problem: C compiler cannot create executables.
!!! Please attach the config.log to your bug report:
!!! /var/tmp/portage/t1lib-5.0.2/work/t1lib-5.0.2/config.log
!!! ERROR: media-libs/t1lib-5.0.2 failed.
!!! Function econf, Line 485, Exitcode 0
!!! econf failed
!!! If you need support, post the topmost build error, NOT this status message.

/var/tmp/portage/t1lib-5.0.2/work/t1lib-5.0.2/config.log内容如下：
| Code: |
This file contains any messages produced by compilers while
running configure, to aid debugging if configure makes a mistake.
configure:726: checking whether make sets ${MAKE}
configure:755: checking for gcc
configure:868: checking whether the C compiler (gcc -O2 -mcpu=i686 -pipe -mieee ) works
configure:884: gcc -o conftest -O2 -mcpu=i686 -pipe -mieee conftest.c 1>&5
cc1: error: invalid option `ieee'
configure: failed program was:
#line 879 "configure"
#include "confdefs.h"
main(){return(0);}
|
我知道这是一个老问题，我也找到了一些解决方法，如下：
缺省地，configure挑选c++作为编译器名字并用-lg++选项的GNU c++链接。如果你正在使用gcc，这个特性在配置期间导致如下问题：
| Code: |
configure: error: installation or configuration problem:
C++ compiler cannot create executables.
|
你可能也在编译期间看到g++、libg++或libstdc++相关的问题。这些问题的一个原因是你可能没有g++，或你可能有g++但无libg++或libstdc++。看一下“config.log”文件。它应该包含你的c++编译器不能工作的准确原因！为了解决这些问题，你可以使用gcc作为你的C++编译器。试试设置环境变量CXX为"gcc -O3"。例如：
| Code: |
shell>CXX="gcc -O3" ./configure
|
它能工作，因为gcc象g++一样编译C++源代码，但缺省地它不链接libg++或libstdc++。解决这些问题的其他方法当然是安装g++、libg++和libstdc++。
可是我还是不知道咋解决？
我是用的gentoo2005.1，g++有，libg++和libstdc++没有
装软件包都是直接emerge的，怎么知道libg++和libstdc++是在哪些软件包里头呢？
用了CXX="gcc -O3" ./configure，好像不行，呜呜
哪位知道怎么解决的给个明白的解决方法好吗？谢谢了[/code] |
