Description Fedora Release Engineering 2020-08-03 17:11:58 UTC
mono failed to build from source in Fedora rawhide/f33

https://koji.fedoraproject.org/koji/taskinfo?taskID=47963830


For details on the mass rebuild see:

https://fedoraproject.org/wiki/Fedora_33_Mass_Rebuild
Please fix mono at your earliest convenience and set the bug's status to
ASSIGNED when you start fixing it. If the bug remains in NEW state for 8 weeks,
mono will be orphaned. Before branching of Fedora 34,
mono will be retired, if it still fails to build.

only ppc64le is failing now, with this error:

/tmp/cc8MKcf4.s: Assembler messages:
/tmp/cc8MKcf4.s:1239: Error: can't resolve `.toc1' {.toc1 section} - `.LCTOC1' {*UND* section}
/tmp/cc8MKcf4.s:1245: Error: can't resolve `.toc1' {.toc1 section} - `.LCTOC1' {*UND* section}
/tmp/cc8MKcf4.s:1291: Error: can't resolve `.toc1' {.toc1 section} - `.LCTOC1' {*UND* section}

on the Internet, I can find this hint:

https://gcc.gnu.org/legacy-ml/gcc/2017-08/msg00111.html
"Maybe you want to
#define USE_TM_CLONE_REGISTRY 0
for your subtarget?"

Comment 2 Dan Horák 2020-08-10 06:42:23 UTC
Have you tried building it with LTO disabled?

Comment 3 Timotheus Pokorra 2020-08-11 11:39:26 UTC
Thanks for the hint!

I inserted now:

+%ifarch ppc64le
+# workaround for LTO being enabled by default
+%define _lto_cflags %{nil}
+%endif

into the mono.spec file, and the scratch build worked fine: https://koji.fedoraproject.org/koji/taskinfo?taskID=49072756

Assigning to Jeff Law, perhaps you want to have a look? Thanks!

This bug appears to have been reported against 'rawhide' during the Fedora 33 development cycle.
Changing version to 33.

Comment 5 Jeff Law 2020-08-11 15:21:52 UTC
Sure.  I'd looked at mono yesterday and marked it as potentially LTO related.  I tried a scratch build with LTO disabled last night, but still had the PPC failure.  At least I thought I did.  But it was a long long day and I could have missed something.  I'll take another look today.

THanks,
Jeff
