Dear all, It seems we're shifting from the original way we were building Cython extensions where each extension was listed in module_list.py to use wildcards in module_list.py. See #7987 and #15410 for wide coverage tickets, and e.g. #17767 for more focused ones.
This is problematic when some file need special linking or should only be optionally compiled. The latter matter was in part dealt with in #18145. For both one the solution is then to explicitly list the problematic files in module_list.py (on top of the wildcard stuff), or to add cython directives in the file itself. That is what was done in #17962. Should progressively convert all files in this direction? That is put Cython directives for linking, including C files and so on, at the top of the pyx file? And uses as many wildcards as possible in module_list.py? If we do so, we definitely need to update the doc at http://www.sagemath.org/doc/developer/coding_in_cython.html. I also take this opportunity to remember everyone that underlinking is bad. Linux is nice enough not to complain at compile time, but some other platforms do. In particular many extensions use functions from GMP (recently lots of files in coding theory and graph theory) but did not list gmp in the libraries to link to. That would be another thing to add to the doc. Best, JP -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
