Mac OSX 上的 C++ 新手问题：使用 f2c（Fortran 编译器）编译——由于宏导致的错误？答案

【问题标题】：C++ newbie problem on Mac OSX: compiling with f2c (Fortran compiler)--errors due to macros?Mac OSX 上的 C++ 新手问题：使用 f2c（Fortran 编译器）编译——由于宏导致的错误？

【问题描述】：

我是一名 C++ 新手，试图在 MacOSX 上编译需要 f2c（用于 Fortran）的代码。我有点超出我的深度，希望能提供任何帮助！

当我做“make”时，我得到了很多错误。我的猜测是这些与f2c有关。 f2c 中可能存在对 Mac 来说是个问题的宏。有没有人遇到过这种事情？有解决办法吗？

以下是错误示例：

【问题讨论】：

你能发布一些生成的代码吗？
嗨 Swegi。您是指我上面发布的代码以外的代码吗？

标签： c++ compiler-construction compilation

【解决方案1】：

似乎f2c生成了一些名称已由您的 C++ 定义的宏。

【讨论】：

嗨 Swegi。谢谢。你能建议如何处理这个问题吗？
我明白你的意思。我想我需要在 C++ 代码中注释掉这些宏。

【解决方案2】：

看起来您正在使用默认的 gcc 4.2 工具链在 Snow Leopard (OS X 10.6) 上。尝试使用旧的 gcc 4.0 工具链，它也可用。

$ cd /usr/bin
$ sudo ln -fs gcc-4.0 gcc
$ sudo ln -fs g++-4.0 g++

如果这没有帮助，您可以按如下方式恢复上述内容：

$ cd /usr/bin
$ sudo ln -fs gcc-4.2 gcc
$ sudo ln -fs g++-4.2 g++

【讨论】：

嗨，保罗。谢谢。我在 OS10.6.5 上。我确实尝试了您的建议，但仍然遇到相同类型的错误。更少——但几乎相同。
