##Building hmatrix on Windows 7

Replace minghc-7.10.2-x86_64\ghc-7.10.2\mingw with mingw from x86_64-mingw32-gcc-4.6.3-release-c,c++,fortran-sjlj.zip Here you have a full Fortran compiler, not shipped with minghc-7.10.2. So you should have the following

$ gcc --version
gcc.exe (niXman's build) 4.6.3
Copyright (C) 2011 Free Software Foundation, Inc.

Then run the mingw-w64 shell installed with msys2-x86_64-20150512. Check again

gcc --version

should be 4.6.3 if not, uninstall gcc from msys

pacman -R gcc

Replace 4 with number of your processors in the following commands or just leave the command make alone.

git clone https://github.com/xianyi/OpenBLAS
cd OpenBLAS
make -j4 NUM_THREADS=4
make PREFIX=/d/Prog/OpenBLAS install

If you don't have make or git, run this.

pacman -Sy git, make

Clone hmatrix

git clone https://github.com/alogic0/hmatrix

then

cd hmatrix/packages/base
cabal install --only-dep
cabal configure  --flags=openblas --flags=windowshack --extra-include-dirs=/d/OpenBLAS/include --extra-lib-dirs=/d/OpenBLAS/bin --extra-lib-dirs=/d/OpenBLAS/lib
cabal build
cabal install  --flags=openblas --flags=windowshack --extra-include-dirs=/d/OpenBLAS/include --extra-lib-dirs=/d/OpenBLAS/bin --extra-lib-dirs=/d/OpenBLAS/lib

or from Win cmd

cd hmatrix\packages\base
cabal install --only-dep
cabal configure  --flags=openblas --flags=windowshack --extra-include-dirs=D:\Prog\OpenBLAS\include --extra-lib-dirs=D:\Prog\OpenBLAS\bin --extra-lib-dirs=D:\Prog\OpenBLAS\lib
cabal build
cabal install  --flags=openblas --flags=windowshack --extra-include-dirs=D:\Prog\OpenBLAS\include --extra-lib-dirs=D:\Prog\OpenBLAS\bin --extra-lib-dirs=D:\Prog\OpenBLAS\lib

Addition

To install cmake

pacman -Sy
pacman -S mingw-w64-x86_64-gsl make

take cmake, tweak it

--- a/Source/cmStandardIncludes.h
+++ b/Source/cmStandardIncludes.h
@@ -168,7 +168,7 @@ namespace std { typedef ios ios_base; }
 # endif
 #endif
 
-#if defined( _MSC_VER )
+#if defined( _MSC_VER ) || defined( __MINGW32__)
 typedef unsigned short mode_t;
 #endif

then

./bootstrap --no-qt-gui --parallel=4

change in cmake_install.cmake string to CMAKE_INSTALL_PREFIX "D:/msys64/mingw64" then

make -j4
make -j4 install
