Link time problem with multiple definition of symbols

[ycollet]

I built protracker on Fedora 36, I've got the following error during link phase:

The workaround I found is to add "-z muldef" in the LDFLAGS env variable.

I found the actual problem, please try again. Remember to remove the "-z muldef" workaround.

Thanks a lot, I will test ASAP :)

[ycollet]

Works fine for me (without -z muldef :) ). I close the ticket !
