Thank you two for the answer.

Eh, even after reading this I was doubting you, but that appears to be
true... I guess asking rpm to add a couple of parenthesis after 32bit
lib requires to at least look like 64bit libs require and not a simple
file require would be asking too much, I never noticed it worked like
this for 32bit libs :/

And rightly enough rpm -qp --requires of "my" gcc does have both
libgcc_s.so.1 while fc30's libgcc.x86_64 only requires the x86_64
version; interesting given the src.rpm is the same.


I've extracted the rpm and am not quite sure where the auto requires
comes from, actually? I thought there was a script doing basically ldd
on each executable (as described on the rpm website[1]), but nothing in
the gcc package seems to require libgcc_s - what am I missing?

I can't see anything obviously different between both build logs, either
copr's[2] or koji's[3] (caution: files are 10MB (compressed) and 55MB
respectively); the logs are too different to diff because of parallel
build but at least lines containing "libgcc_s" are similar enough...

Will look into how autodepends works a bit more, I'm curious why this is
different.


Thanks,
