Re: Windows misbehavior compiling Base (toolchain.c ?)

["Johnson, Andrew N. via Core-talk" <core-talk at aps.anl.gov>]

I just restarted the build of this PR after downloading the full build log of the one job that failed after 1 hr:

Build EPICS Base 7 base-7.0-1411 failed

Commit 43d6ed95f2 by Jeremy Lorelli on 12/22/2024 8:25 PM: 
Add EPICS_DIAGNOSE_AS attribute for clang

The symptoms look different but may be related: In this case toolchain.c was successfully built, but despite the job being stopped after the 1hr the last entry in the log was at 00:19:36.

Note that our CI log-files don’t include any command(s) which hang, and even making the build verbose probably won’t fix that. We give GnuMake the flags --j<n>  --output-sync=target which only logs the commands it executed and their output after they are done, either successfully or by failing. Another build follows the above line with this linker command to create the qsrv.lib so that might be the cause here:

Just another $0.02 with further evidence.

Dear colleagues,

 

Working on a feature branch for ci-scripts, I am puzzled about failing AppVeyor builds, e.g.

    ci.appveyor.com/project/epics-modules/ci-scripts/builds/51276973

where a large number of VisualStudio builds are consistently getting stuck in Base at or after compiling 'toolchain.c'.

I repeated the build a few times - this is a hard issue.

 

Does anyone have an idea what could be going on?

 

Clueless,
