我为客户做的一些工作要求我在 Red Hat Enterprise 上使用非常旧版本的 gcc 进行构建。我们最近从 4.x 转移到 5.3，当我尝试构建简单示例时遇到了一些编译错误：

#include <iostream>

int main()
{
    std::cout << "Hello World" << std::endl;

    return 0;
}

我得到以下信息：

bash-3.2$ g++ -o hello hello.cpp
In file included from /opt/ext/gcc-3.2.3.34rh/include/c++/3.2.3/bits/stl_alloc.h:90,

                 from hello.cpp:1:

__LOCK_INITIALIZER是一个 pthreads 宏，但显然我没有在这里直接使用它。有没有人以前见过这种问题，或者可以提供任何可能的建议作为你为什么会发生这种情况？

您的 LD_LIBRARY_PATH 设置为什么？特别是 gcc 依赖于 libgcc* 和 libstdc++* （尽管如果您已经静态链接它，那应该不是问题）。如果这是一个问题，请尝试将您的 LD_LIBRARY_PATH 设置为 /opt/ext/gcc-3.2.3.34rh/lib:$LD_LIBRARY_PATH。
