Hi list,
I have updated mame packages to 0.186 yesterday. The package built
fine on rawhide [1] and f26 [2], as well as on non-i686 on f25 and
f24. On f25 [3] and f24 [4] i686, the build has failed with the
following message: virtual memory exhausted: Operation not permitted
How much memory do the builders have?
it probably has nothing with the amount of memory in the builder (see
hw_info.log for the details), but rather it exhausts the 32-bit address
space for one process, where there are ~3GB user usable out of the
theoretical 4GB. Likely the sum (*.o) processed by ar is bigger than
the user usable portion. The workaround is usually to decrease the
debuginfo size with eg.
%global optflags %(echo %{optflags} | sed 's/-g /-g1 /')

Hi,
the build succeeded on i686 on f26 and f27 - could it be that gcc-7 is
more memory-efficient? It also succeeded on armv7hl on all supported
arches. Maybe it is just on the edge of 3 GB...
In any case, I am already at -g1:
RPM_OPT_FLAGS=$(echo $RPM_OPT_FLAGS | sed -e "s@-g@-g1@")
Does it make sense to go down further to -g0?
Best regards,
Julian
Try building without parallel build on %{ix86} and keep -g1:
%ifnarch %{ix86}
%make_build
%else
%{__make}
%endif
and see if that helps.
Cheers
Björn
Thanks for the tip! Unfortunately, even with -g stripped entirely and
without parallel build the memory exhaustion still happens. Oddly
enough, without -g alone it happens on bfm_sc4.cpp, but without -g and
without parallel build it happens on mpu4.cpp.
Is there anything else to try, or is it time to ExcludeArch: %{ix86}?
Besided using ExcludeArch, I'd either keep the old versions for fc24 and
fc25 (if any) or work with upstream to split the source-files which
cause OOM into several smaller ones, so you can build the whole thing
with full debug enabled again on all arches.
