[Plib-users] cross-compiling with mingw32

[Benjamin E. T. <be...@cs...>]

hi,

I've just started working with plib, and thought others might find this
useful:

To cross compile a windows plib binary from linux:

1) Install the mingw32 (also called xmingw32) tools. These can be emerged,
apt-gotten, yummed, or whatever your favorite way of installing is.

2) compile plib using the mingw32-g++ compiler. The following should work:
bash$ ./configure  --build=i686-linux --target=i386-mingw32 --host=i386-mingw32 --prefix=/usr/local/i386-mingw32

(where prefix is the location of mingw. it might be /opt/xmingw for example)

3) I've been using the following makefile, and it has worked fine so far,
although I might have left something out, since I haven't tested all the
plib functions. You'll have to change it slightly to fit your system and
project/object names, but this should serve as a good starting point.


best,
ben

p.s. sorry if i'm posting this twice. i didn't see it go through the first
time...
