使用GCC编译32位程序时出现奇怪的错误

3

当我在64位Linux上使用GCC编译一个简单的32位C程序时，会收到以下信息：

我该怎么办？

看起来你只有64位版本的GCC。 - Alex Lop.

你使用的是哪个Linux发行版？你是如何安装GCC的，从哪里安装的？如果你是从源代码编译GCC的，你是如何配置它的？ - Ruslan

@Ruslan，我使用了带有GNAT Community IDE的GCC。 - FlatAssembler

看起来，根据另一个与GPS相关的问题，GPS附带的GCC编译时没有支持多库的选项。如果你运行gcc -v，你会注意到输出中提到了--disable-multilib选项。

我猜你现在就没辙了。你要么自己构建GCC，要么从与GPS无关的来源（例如Linux发行版的仓库）安装它。然后，你需要以某种方式告诉GPS使用这个其他版本的GCC。
