I've just set up MinGW environment following this post
But how to add 3rd party libraries to it?
回答1:
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
}
To compile this, you could use the command line:
gcc main.c -Ifoo/inc foo/lib/foo.a -o main.exe
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 :-)
回答2:
No different from any other system using gcc
- get the sources
- untar
- run configure -- this may require a tweak or two
- make
- make install
and now use your new library with proper -Lfoo/bar -lfoobar switches.
I recommend the MSys system around MinGW in order to do all this.
回答3:
I just went through figuring this out myself. I strongly recommend reading the linking howtos on the MinGW webpage. Read them carefully as there is quite a lot to take in. They are quite thorough though so it's well worth your time.
There are essentially two ways of doing things. First, you can just regard MinGW as a compiler, because that's what it is, and invoke it from cmd.exe (the command prompt) or an IDE. The other way to do it is to use MSYS which is basically a Unix style shell that you can run on Windows to use Unix style build tools like configure and make.
For either of these you really have to read the howto I linked above to understand how dependency paths are being searched. I hesitate to explain it here as it is already explained in the howtos and duplicating that information is not a good idea. If you have specific questions after reading them I'd be happy to offer more help.
