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, and a fortran compiler can be obtained from MinGW-w64 as described here.

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.
