Hi,<br><br>I&#39;m trying to compile a C program on Windows XP 64 bit with the mingw-w64 compiler. But I&#39;m getting errors as follows. <br><br>I downloaded the MPICH2 lib from: <a href="http://www.mcs.anl.gov/research/projects/mpich2/">http://www.mcs.anl.gov/research/projects/mpich2/</a>.<br>
And downloaded the mingw compiler from: <a href="http://www.drangon.org/mingw/">http://www.drangon.org/mingw/</a> (mingw-w64-bin-x86_64-20100131.7z)<br><br>Note that the program compiles successfully with the 32 bit mingw compiler and the 32 bit MPICH2 (mpich2-1.2.1-win-ia32.msi).<br>
