我尝试在 Fedora 24 上使用 GCC 构建 VBA-M，但收到此错误:

我已经尝试export CXX=clang++; export CC=clang，但这给了我不同的错误。
错误是在我正在编译的代码中，还是在标准库中？是否有我需要安装的软件包，或者有什么方法可以解决这个问题？我应该直接编辑包含文件吗？
最佳答案
我在 Arch Linux 上构建时遇到了同样的问题。问题在于 expr.cpp 文件包含命名空间内的内容。如果您同时查看 expr.ypp 和 expr.cpp，您会看到如下内容:
namespace std {
#include <memory.h>
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
}
问题出在命名空间内。我更改为这个，现在可以使用了:
#include <memory.h>
#include <stdio.h>
#include <cstdlib>
#include <string.h>
希望对你有帮助!
