On windows, with anaconda, is there a procedure to use pythran by calling side-loaded compiler (e.g. from winlibs).

Hello, Pythran is a wonder !

I use pythran myself for sppeding up computation for scientifical interests, and I would like to share my scripts with a user. Th problem is that user has a Windows system, and is able to install anaconda, but installing Visual build tools requires administrative rights.
However, the site winlibs.org provides a bundle of pre-compiled clang compiler with LLVM and omp capabilities, that is therefore usable just by downloading the bundled binaries.
Now, let's say a user has anaconda installed with the pythran module, and the winlibs package downloaded... What will eventually be the procedure to manage to compile a .py file with pythran ?

Hi @hprodh and thanks for the kind words. I don't have a lot of windows experience, so I can't tell for the details, but I do know where you should be looking at: https://pythran.readthedocs.io/en/latest/MANUAL.html#customizing-your-pythranrc
Setting CC= and CXX= to the binaries from winlibs should be a good start.

The default on windows is

[compiler]
defines=
undefs=
include_dirs=
libs=
library_dirs=
cflags=/std:c++14 /w
ldflags=
blas=pythran-openblas
CC=clang-cl.exe
CXX=clang-cl.exe
ignoreflags=
