汇编/链接到开罗图书馆

标签: gcc compilation include cairo

我正在尝试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Cairo库 - 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)

我正在尝试像这样编译:

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

我的cairoTest.c文件以:

开头
include <cairo.h>

gcc正在查找cairo.h,但它提供了以下错误消息。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库包含在我的编辑中?

谢谢,

答案 0 :(得分:7)

尝试使用

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

(但您可能需要其他库,可能是$(pkg-config --cflags --libs cairo)或类似的)

您的文件应以

开头
 #include  <cairo.h>
