Question

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构建。我们最近从4.x转移到5.3，当我尝试构建简单的示例时，我遇到了一些编译错误：

#include <iostream>

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

    return 0;
}

我得到以下内容：

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 /opt/ext/gcc-3.2.3.34rh/include/c++/3.2.3/iostream:45,
                 from hello.cpp:1:

__LOCK_INITIALIZER是一个pthreads宏，但显然我不是直接在这里使用它。有没有人见过这种问题，或者可以提供任何可能的建议，为什么会发生这种情况？

你的LD_LIBRARY_PATH设置为什么？特别是gcc依赖于libgcc *和libstdc ++ *（尽管如果你静态地链接它应该不是问题）。如果是一个问题，请尝试将LD_LIBRARY_PATH设置为/opt/ext/gcc-3.2.3.34rh/lib:$LD_LIBRARY_PATH。

在RHE 5.3上使用gcc 3.2.3进行编译
