问题描述
我刚刚按照
但是如何向其中添加第三方库?
But how to add 3rd party libraries to it?
推荐答案
一个库由两个主要组件组成-C头文件和已编译的目标代码档案. GCC有各种各样令人困惑的方法来指定这些内容，但是假设您使用的是位于相对目录路径foo/lib中的库foo.a和位于foo/inc中的标头foo.h.您自己的C代码位于main.c中，如下所示:
A library consists of two main components - the C header files and the compiled object code archive. GCC has a bewildering array of ways of specifying these things, but let's say you are using a library foo.a which lives in the relative directory path foo/lib, and a header foo.h which lives in foo/inc. Your own C code lives in main.c and looks like this:
#include "foo.h"
int main() {
return FooFunc(); // call function in foo.a
}
要对此进行编译，可以使用命令行:
To compile this, you could use the command line:
gcc main.c -Ifoo/inc foo/lib/foo.a -o main.exe
-I标志将添加到搜索标头的路径中.您也可以添加到lib路径，但是事情开始变得复杂:-)
the -I flag adds to the path searched for headers. You can also add to the lib path, but then things start to get complicated :-)
