CFD Online Discussion Forums - ParMETIS and gcc-4.4

Uhm... now that I've re-read the first post, it reminded me that I also have had one of those issues. The two solutions I've used are:

As for the implicit declaration, try this: edit the files "$WM_THIRD_PARTY_DIR/ParMetis-3.1/ParMETISLib/proto.h" and "$WM_THIRD_PARTY_DIR/ParMetis-3.1/METISLib/proto.h" and remove the comments from

Code:

/*void GKfree(void **,...); */

I had to do this months ago to get it to cross-compile with MinGW.
If the other issue persists, try downloading this package and retrieve the gcc folder from it; it has gcc-4.4.2 pre-release. It's from the MinGW-w64 project and has worked well for me, both in compiling for Linux (32 and 64bit) as well as creating the cross-compiler Mingw-w32/64 Linux to Windows.

The script I use for building the gcc-4.4.2 (and gcc-4.5.0), modified from the makeGcc that comes with the ThirdParty package, is this:

Sorry for not attaching it in a file, but I didn't feel like tar.gz'ing it.

Good luck! Hope it works.
