汇编/链接到开罗图书馆

Question

我试图测试一些简单的开罗程序,但我无法确定如何包含源文件.我已经安装了开罗图书馆 - 这只是一个如何让gcc知道的问题......

• 我在/ usr/local/include/cairo中安装了.h文件(包括cairo.h)
• 我在/ usr/local/lib和/ usr/local/lib/cairo中安装了.dylib文件

我应该注意安装的其他任何组件吗？(我刚刚'make install'来安装库)

我想像这样编译:

$ gcc cairoTest.c -I/usr/local/include/cairo -L/usr/local/lib/

我的cairoTest.c文件以:

include <cairo.h>

gcc正在查找cairo.h,但它给出了以下错误消息.我认为它没有正确链接到.dylib文件,但我不确定.我还是新编译/链接.

gcc cairoTest.c -I/usr/local/include/cairo -L/usr/local/lib/cairo

我应该采取哪些不同的方式将Cairo库包含在我的编译中？

谢谢,

尝试编译

 gcc -Wall -g cairoTest.c -I/usr/local/include/cairo -L/usr/local/lib/ -lcairo -o cairoTest

(但你可能需要其他库,可能是通过$(pkg-config --cflags --libs cairo)或类似的)

你的文件应该从

 #include  <cairo.h>
