Re: How to build Python3 support into GNATCOLL with alire

Hi Simon,

I have not used alire myself, but I noticed the following in your message:

Although running external scripts from gprbuild is indeed unlikely, it is definitely in the realms of gprconfig (which is run first to generate the .cgpr config file).
For this one would need to provide some .xml file that explains what command to run, and what to generate in the .cgpr file (likely adding some `-I` compiler
switches for C files).
