[petsc-users] Petsc-3.4.2 with MinGW-w64 on Windows 7

[Mengda Wu]

Hello all,

   I am trying to compile 64 bit version of petsc-3.4.2 using MinGW-w64
(latest version 4.8.1 installed with
http://sourceforge.net/projects/mingwbuilds/files/mingw-builds-install/mingw-builds-install.exe/download)
on Windows 7 64 bit. I have cygwin, python (under cygwin) installed.

  I run the "$ ./config/configure.py --with-cc='gcc' --with-fc='gfortran'
--with-cxx='g++'
--with-clanguage=cxx  --with-mpi=0 --with-debugging=0  --with-sowing=0
--with-c
2html=0". I got some errors in checkCCompiler. The log file is as follows:
============================================================

compilation terminated.
============================================================

I think the problem is the MinGW-w64 compiler does not recognize the cygwin
path like /tmp. Is there a workaround? I tried to use a native Windows
python, but the configure fails to find the "make" command then. I guess
MinGW may be not supported by PetSc yet.

However, I found someone has successfully compiled a MPI-version Petsc on
Windows 64 bit. Here is the link:

How is that possible?


Thanks,
Mengda
