Hi Ruben,
thanks for this very very good pointer!! I did not dare look behind
the scenes of the MinnGW packages, but it turns out that was my
mistake, they are indeed readable, and helpful! :-)
One more question, if I may: in the PKGBUILD you pointed out, there
seems to be a "wild" :-) mix of recommended packages from mingw and msys.
Is there an easy beginners guideline which package to prefer if both
exist, something like: always prefer mingw-package over msys-package?
Should I use python2 from msys or mingw? Or install both? For another
build, I tried cmake from msys and miserably failed, whereas cmake from
mingw worked out of the box. Is mingw usually "preferable"?
Thanks for your help, and all the best,
Mario
