# Installing MinGW

This is slightly experimental, but we have built Vorpal with it, and it is currently our only path to building facetsall.

This is for 64 bit only.

* Install the latest compilers from http://tdm-gcc.tdragon.net/download.  The webdl installer is recommended.  Assuming the version is 5.1.0-2, install into C:\TDM-GCC-64\5.1.0-2.

* This should add `C:\TDM-GCC-64\5.1.0-2\bin` correctly to the end of your Windows path, but one should check.

* Most recent attempt required installing binutils to be able to create libraries with the mingw ar.  Will need some more sorting out, as previously found:

NumPy build failure with incorrect MinGW binutils:

~~~~~~

generate_def(dll_file, def_file)

File "C:\Users\jsalvatier\workspace\numpy\numpy\distutils\mingw32ccompiler.py", line 282, in generate_def

raise ValueError("Symbol table not found")

~~~~~~

To make your mingw paths consistent, do

~~~~~~

mount binary C:/TDM-GCC-64 /TDM-GCC-64

~~~~~~

in the bash shell.

To make this permanent, put

~~~~~~

C:/TDM-GCC-64 /TDM-GCC-64 ntfs binary 0 0

~~~~~~

as one line in /etc/fstab.

[Installing ATLAS on Windows] requires that one link the MinGW compilers into /usr/bin as follows for 64-bit:

~~~~~~

cd /usr/bin

ln -s /TDM-GCC-64/5.1.0-2/bin/x86_64-w64-mingw32-gcc.exe .

ln -s /TDM-GCC-64/5.1.0-2/bin/x86_64-w64-mingw32-g++.exe .

ln -s /TDM-GCC-64/5.1.0-2/bin/x86_64-w64-mingw32-gfortran.exe .

# MPI for MinGW

These notes have not been upgraded in a while.

A useful reference is http://www.symscape.com/configure-msmpi-for-mingw-w64.

* Copy the Microsoft HPC Pack 2008 SDK distribution to a new place:

~~~~~~

cd /winsame

mkdir contrib-mingw

cd contrib-mingw

mkdir microsoft-hpc-mingw

cd microsoft-hpc-mingw

cp -R /cygdrive/c/Program\ Files/Microsoft\ HPC\ Pack\ 2008\ SDK/* .

~~~~~~

* Add `#include <basetsd.h>` to the copied mpi.h as line 304.

* If `msmpi.dll` is not in `/winsame/contrib-mingw/microsoft-hpc-mingw/Lib/amd64`, there may be a copy of `msmpi.dll` in `C:\\Windows\\System321 that you can copy over.  If so, do the following before the above.

~~~~~~

cp /cygdrive/c/Windows/System32/msmpi.dll /winsame/contrib-mingw/microsoft-hpc-mingw/Lib/amd64 # For 64 bit, otherwise i386

~~~~~~

* Once `msmpi.dll` is in `/winsame/contrib-mingw/microsoft-hpc-mingw/Lib/amd64` do the following:

~~~~~~

cd /winsame/contrib-mingw/microsoft-hpc-mingw/Lib

cd amd64

/TDM-GCC-64/5.1.0-2/x86_64-w64-mingw32/bin/gendef msmpi.dll # creates msmpi.def

/TDM-GCC-64/5.1.0-2/x86_64-w64-mingw32/bin/dlltool -d msmpi.def -l libmsmpi.a -D msmpi.dll 

~~~~~~

The build system for your project then will need to add the flags

* `-I/winsame/contrib-mingw/microsoft-hpc-mingw/Include/mpi.h`

* `-L/winsame/contrib-mingw/microsoft-hpc-mingw/Lib/amd64 -lmsmpi`

for compiling and linking.

### MPI for MinGW Fortran ###

* modify mpif.h by adding the following as line 9:

~~~~~~

use ISO_C_BINDING

~~~~~~

Change the line 308 (309 now that you've added the above as line 9) to read

~~~~~~

PARAMETER (MPI_ADDRESS_KIND=C_INTPTR_T)

~~~~~~

* modify mpi.f90 by adding the following as line 10:

~~~~~~

use ISO_C_BINDING

~~~~~~

Change line 311 (312 now that you've added the above as line 10) to read

~~~~~~

PARAMETER (MPI_ADDRESS_KIND=C_INTPTR_T)

~~~~~~

and compile to generate the module files:

~~~~~~

$ mingw32-gfortran.exe -o mpigf.o -c mpi.f90 && rm mpigf.o

~~~~~~

The link flags are now:

* `-L/winsame/contrib-mingw32/microsoft-hpc-mingw/Lib/amd64 -lmsmpifec -lmsmpi`
