Question

当我尝试在64位Linux上使用GCC编译简单的32位C程序时，出现以下消息：

[teo.samarzija@teos-acer-laptop debug]$ gcc -m32 -o program program.c

我该怎么办？

Answer 1

从another GPS-related question看，GPS似乎是随GCC一起编译的，不支持multilib。如果运行gcc -v，您会注意到输出中提到的--disable-multilib选项。

那我想你很不走运。您要么必须自己构建GCC，要么从其他与GPS不相关的来源进行安装：从Linux发行版的存储库中。然后，您必须以某种方式告诉GPS使用该版本的GCC。

使用GCC编译32位程序时出现奇怪的错误
