当尝试在 Mac OS X 10.8 上使用 make make 构建 FreeImage 3.1.5.4 时，出现以下错误 g++-4.0: No such file or directory。关于编译器配置的 makefile 有问题。如何解决这个问题？

【解决方案1】：

FreeImage 3.1.5.4 的makefile.osx 对于 OS X 版本 > 10.6 已过时。请参阅这篇文章的底部以获取修改后的版本。除了解决FreeImage issue tracker 中描述的问题之外，您还需要在Source/OpenEXR/IlmImf/ImfAutoArray.h 中添加一行：

#include <cstring>

适用于 OS X 10.8 的 Makefile：

# -*- Makefile -*-
# Mac OSX makefile for FreeImage

# This file can be generated by ./gensrclist.sh
include Makefile.srcs

# General configuration variables:
CC_X86_64 = gcc -4.2
CPP_X86_64 = g++ -4.2

作为克里斯托夫回答的补充：

答案中提到的GCC 4.2 已经过时了，FreeImage 使用Clang 编译得很好。所以，我建议切换到Clang 工具链。

你是对的！但我认为这作为评论会更好。
