[petsc-users] win32fe?

[Satish Balay]

Assuming 'icx/ifx' compiler options are same as 'icl/ifort' - you can try:

--with-cc='win32fe icl --use icx' --with-cxx='win32fe icl --use icx' --with-fc='win32e ifort --use ifx'

Also check 'win32fe --help'

However I think the above assumption [i.e icx is a drop in replacement for icl] is likely invalid - so this might not work.

Note: petsc/main has shell wrappers for 'win32fe icl' - so one could add similar wrappers for  icx - if the above would work.

$ cat lib/petsc/bin/win32fe/win_cl

${p}/win32fe cl $*


The sources for win32fe are at https://bitbucket.org/petsc/win32fe

And 'win32fe icl --verbose' is useful to understand the commands its invoking internally.
