This is a lot of work, I know since I've cleaned this up for all Python modules.

Maybe this is going to change somewhen :-) We should aim to the top, not the status quo :-) > My understanding is that the concept of "native-inputs" for a package > only makes sense when that package uses a build system that can > cross-compile, This is my understanding, too. But the python-build-system might be able to cross-compile somewhen and then this information is essential. >> And for extension modules it would allow compiling on a faster >> environment (e.g. x86 vs. ARMv4). >> >> (I was not aware of python packages are not cross-compiled, thus I can >> only guess the reason why this is not possible: Python distutils may not >> be able to *cross*-compile extension modules.

Extension modules are simply modules or libraries written in C/C++ or other languages. Even modules written in Cython would be counted in here, since they are translated to C and then compiled into platform dependent code. > In any > case, it doesn't change the fact that today, the python-build-system > does not cross-compile. In any case, this is a current limitation only :-) -- Regards Hartmut Goebel | Hartmut Goebel | h.goe...@crazy-compilers.com | | www.crazy-compilers.com | compilers which you thought are impossible |
