CrossCompilation for w32 with MinGW (http://www.mingw.org) on linux-systems
you need a cross-compilation tool-chain for windows (there is a debian-package mingw32)
- set the CC-environment-variable to the cross-compiler and export it
- set the STRIP-environment-variable to the strip-version that comes with the toolchain and export it
- set the CFLAGS-environment-variable to "-mms-bitfields" and export it (this is highly necessary to
- run the external if pd was compiled with M$-vc)
run "./configure" and specify the path to your "m_pd.h" (with --includedir) and to your "pd.lib" (with --libdir)
don't forget to override the default extension ("pd_linux" on linux-systems) with the more appropriate "dll".
on bash this looks like:
- % export CC=i586-mingw32msvc-cc
- % export STRIP=i586-mingw32msvc-strip
- % export CFLAGS=-mms-bitfields
- % ./configure --includedir=/path/to/w32-pd/src/ -libdir=/path/to/w32-pd/bin/ -with-extension=dll
+ % ./configure --with-extension=dll --host=i586-mingw32msvc --includedir=/path/to/w32-pd/src/ -libdir=/path/to/w32-pd/bin/
now run "make" and enjoy.
