[Mono-dev] Strange build problem

[Alexander Köplinger]

Hey,

Are you sure you’re running this on the nealef-s390x-2 machine and not nealef-s390x-1 ?
This sounds exactly like the problem with the ancient gcc we ran into on the -1 machine, that’s why we’re only using the -2 machine on Jenkins now.

In fact, my IRC log shows we discussed this back in October 2015:

<directhex> neale: still no success compiling on nealef-s390x-1, with -O2
<directhex> https://jenkins.mono-project.com/job/z/label=centos-s390x/2065/parsed_console/log_content.html#ERROR1
<directhex> System/AndroidPlatform.cs(66,246): error CS1525: Unexpected symbol `end-of-file', expecting `end-of-file'
<directhex> ._.
<neale> directhex: At least it got rid of the inline errors problem ;-)
<directhex> yes this is technically true
<neale> I've never seen this particular problem before
<directhex> maybe a checkout problem? want to delete the workspace?
<neale> The z workspace?
<akoeplinger> hmm, it affects all files that are completely #ifdefed out
<neale> Yup
<directhex> neale: yes
<neale> z gone\
<directhex> it's renamed to "z" because the same job also handles windows builds, and windows has a silly low PATH_MAX
<directhex> which the old name was causing errors for
<neale> Ah
<directhex> so single-char job names if they run on windows
<neale> I ran a build in /home/jenkins/workspace/test-mono-mainline-communityarchitectures/label/centos-s390x (From Sep28) and forced a recompile of Android.cs which has the same ifdef situation and the build was clean.
<directhex> that job name is the old "z" job
<directhex> see, very long name, poor windows
<neale> Understood, just wanted to point out that a build used to work for those files

AFAIK we never got past that problem on the -1 machine, so we just stopped using it.
