error: cannot run C compiled programs.

以前一直都是用的x86，昨天帮人装系统(pentiumD+945），尝试用amd64.但是没装多久就碰到了这个问题。一个出在grub上，一个出在gcc上。

我在gentoo的handbook上看到有说明讲amd64不能用grub，需要用grub-static，所以grub的问题还可以解决。但是gcc的问题我找了不少资料都没有什么解决办法。（forums.gentoo.org上有人说用 USE="multilib" FEATURES="-sandbox" emerge gcc，但是也不行）
我估计后面还会碰到这个问题（例如glib什么的），所以这个问题不解决amd64的系统估计弄不好了。
请问各位有没有相关的经历和解决办法。

以前只知道amd64很多东西不能用，不知道现在是不是还是这样？还是换回x86把

jjj311

gcc-config -l
然后gcc-config **
换一个gcc，然后env-update && source /etc/profile
行吗？应该是编译器链接的问题……

ZDN

grub可以在amd64用的.
应该还是别的地方的问题,看了你的emerge info倒是没发现可疑的地方.

1. 
   
2. gcc-config  -l
   

复制代码

看看输出什么?

把 /usr/bin/x86_64-pc-linux-gnu-gcc 移走，再试试

看看是不是这个

druggo

把失败的config.log贴上来看看，到底是为什么出错，你可以自己手动按照里面写的步骤测试一下。

楼主是不是用了ccache-config了？我上次出现这问题是这原因……
