libpng一起在Mac OS X编译C程序 [英] Compile a C program with libpng on Mac OS X

问题描述

我有一个小工具，我用C写使用的libpng。在Linux下，我只安装的libpng-dev的和做GCC myapp.c /usr/lib/libpng.so -o的myapp。在Mac OS X中，我已经安装了X code的工具，我相信包括的libpng。我怎么联系起来反对，我需要指定png.h包括路径？

I have a little utility I wrote in C that uses libpng. Under linux, I just install libpng-dev and do "gcc myapp.c /usr/lib/libpng.so -o myapp". In Mac OS X, I have the Xcode tools installed, which I believe includes libpng. What do I link against, and do I need to specify an include path for png.h?

推荐答案

尝试/usr/X11/include/png.h - 你会发现在../lib的库（或/ usr / X11 / lib目录）作为好。

Try /usr/X11/include/png.h - you'll find the libs in ../lib ( or /usr/X11/lib ) as well.

修改小牛不会出现这个了。您可能需要使用自制或的 MacPorts的，以便安装的libpng。

EDIT Mavericks doesn't appear to have this anymore. You may need to use homebrew or MacPorts to install libpng.
