# Installing ATLAS on Windows #

ATLAS is a moving target.  With each version, configuration changes.  It could once use the clapack_cmake sources, but as of 3.10.X, it appears that one must have a fortran compiler and one must build with the full lapack.

Cygwin should be installed as described [here](Preparing a Windows machine for Bilder), and a fortran compiler can be obtained from MinGW-w64 as described [here](Installing MinGW).

On Windows 7, you must turn off user notification in UserAccountControlSettings and reboot to build ATLAS.  If not, you may see

~~~~~~~~~~~~~~

cd bin/ ; ./xatlas_install -1 0 -a 1

/bin/sh: ./xatlas_install: Permission denied

make[1]: *** [build] Error 126

~~~~~~~~~~~~~~

ATLAS appears to have problems with parentheses in paths.  To get around this

 * On Win64 do

~~~~~~~~~~

mkdir /ProgramFilesX86

mount "C:/Program Files (x86)" /ProgramFilesX86

~~~~~~~~~~

and additionally source `bilder/setatlaspath.sh`.  Check your path afterwards.  Our current observation is that this removes only some irrelevant directories from the path, but your mileage may vary.  At this point, a simple configuration command like

~~~~~~~~~~

<path to your>/configure \

  --prefix=/winsame/contrib-vs9/atlas-3.11.17-ser \

  -b 64 \

  --with-netlib-lapack-tarfile=<path to your>/lapack-3.4.2.tgz

~~~~~~~~~~

(where 64 might be replace by 32) should succeed.
