Is pythran usable on windows without admin provileges ?

[hprodh]

Hello, Pythran is a wonder !

I use pythran myself for speeding up computation for scientifical interests, and I would like to share my scripts with a user. The 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=

I could not to find a solution for this issue, I also don't need myself to solve it anymore, yet it might remain an issue so I do not close it for now (but I renamed the issue for clarity).

It would be interesting to know if one can use Miniforge to install the clang conda package and use it for Pythran compilation. I'm not totally sure that we can use this package without installing Visual build tools.
