mono-4.0.1-8.fc23 (with bootstrap 1) does not build on ppc64le in rawhide

Comment 1 Timotheus Pokorra 2015-05-27 07:21:52 UTC 
You can ignore the errors about Novell.Directory.Ldap, they seem to appear on the build logs for x86_64 as well, but the build should succeed anyway.

The real problem is the System.TimeZoneNotFoundException.
The exception is thrown here: 
https://github.com/mono/mono/blob/mono-4.0.0-branch/mcs/class/corlib/System/TimeZoneInfo.cs#L88

Please have a look at the function TimeZoneInfo CreateLocal () at
https://github.com/mono/mono/blob/mono-4.0.0-branch/mcs/class/corlib/System/TimeZoneInfo.cs#L121

This refers also to https://github.com/mono/mono/blob/mono-4.0.0-branch/mcs/class/corlib/System/TimeZoneInfo.cs#L163
defining timeZoneDirectory enclosed in "#if LIBC".

Will this help you to work on a patch?
Comment 2 Than Ngo 2015-05-28 11:28:49 UTC 
thanks for your info, i will give a try and will report the results asap.

Comment 3 Than Ngo 2015-05-28 23:27:53 UTC 
Timotheus, i debug the mono codes and found that the error caused by this line

var list = new List<KeyValuePair<DateTime, TimeType>> (count);

in the function.

static List<KeyValuePair<DateTime, TimeType>> ParseTransitions (byte [] buffer, int index, int count, Dictionary<int, TimeType> time_types)

It's really strange, because this line looks correct for me

however i cannot get the backtrace. Do you know how i can get backtrace in mono instead exception?

It will help me to know why it crashes in this line.

Thanks
Comment 4 Dan Horák 2015-06-05 08:02:25 UTC 
so it's the hardening (https://fedoraproject.org/wiki/Changes/Harden_All_Packages) that breaks the compiler, with

I get http://ppc.koji.fedoraproject.org/koji/taskinfo?taskID=2525410 - all green. It's not only ppc64le that's broken with hardening, on s390x I see segfaults.
Comment 5 Dan Horák 2015-06-05 08:05:41 UTC 
For the record, disabled hardening does not help on ppc64. Also the main change between F-22 (where my scratch builds succeeded) and F-23 (where it was failing) is the hardening.
Comment 6 Till Maas 2015-06-05 08:28:24 UTC 
Do I understand correctly, that it fails to build on ppc64le because of the hardening but on pcc64 for unknown reasons? And s390x also needs hardening disabled?

yes, ppc64 is different issue (#1225035), s390x is now tracked in #1228570. IBM should be looking at both the ppc64 failures (with some fixes already in the queue, but not public yet) and I'm in contact with the s390x upstream Mono maintainer.
Comment 8 Timotheus Pokorra 2015-06-18 05:45:41 UTC 
I just saw https://github.com/mono/mono/pull/1868 which was merged 6 days ago:
"[ppc] Basic powerpc64 little endian enablement"

would that resolve some issues for the build as well?
Comment 9 Than Ngo 2015-07-06 20:29:34 UTC 
no, i have applied the patches and rebuilt moni, the build faulure still happens, but on somewhere.
Comment 10 Jan Kurik 2015-07-15 14:06:42 UTC 
This bug appears to have been reported against 'rawhide' during the Fedora 23 development cycle.
Changing version to '23'.

(As we did not run this process for some time, it could affect also pre-Fedora 23 development
cycle bugs. We are very sorry. It will help us with cleanup during Fedora 23 End Of Life. Thank you.)

More information and reason for this action is here:
https://fedoraproject.org/wiki/BugZappers/HouseKeeping/Fedora23
Comment 11 Than Ngo 2015-08-28 11:09:53 UTC 
this issue is fixed in rawhide and f23
