Hi,
Personally on my build machine [1] I've never had a problem to build
QGIS master.
Rainer, some questions:
- did you compile from scratch or via our infrastructure
(ports/poudriere/synth?)?
- did you have the same problem with FreeBSD 11 or 12?
- can you try with llvm 6 or 7 from ports (I think that FreeBSD 13 have
llvm 8 by default)?
Regards,
Loïc

As the maintainer of the QGIS port for FreeBSD, I am preparing a port
for the recent update to QGIS 3.8.0.
This seems to happen since #18fb3f2 [1] (committed 2019-05-13, submitted
2019-04-30). Before the commit, the build process takes a normal
duration on FreeBSD.
As far as I can say, the problem occurs with both proj-5.1.0 and
proj-6.1.0. GDAL version is 2.4.1, the OS is FreeBSD 13-0 CURRENT amd64.
Hmm - perplexing. Most of that commit should be ifdefed out for proj <
6 builds. I wonder if you tried trimming the contents of
qgscoordinatereferencesystem_legacy.h to just a couple of sample lines
as a test? Maybe there's something in the compiler which doesn't like
the large static QMap...
Nyall
Many thanks for your response.
After trimming the contents of qgscoordinatereferencesystem_legacy.h
(about 10 lines left), it builds in a normal time again.
So it is likely, that the problem on FreeBSD has something to do with
its compiler suite? I am using FreeBSD clang version 8.0.1
(branches/release_80 363030) (based on LLVM 8.0.1).
Is there any workaround, which lets me use the whole contents again?
You could try swapping the QMap for a std::unordered_map and see if
there's any benefit.
Nyall
I am afraid I have no clue how to do this, because I am not a c++ coder.
Is it within qgscoordinatereferencesystem_legacy.h
(sAuthIdToQgisSrsIdMap?) or better in qgscoordinatereferencesystem.cpp
(at lines:386-405?).
As I said in my initial posting, the build duration problem exists on
both, proj 5.1.0 and 6.1.0 on FreeBSD ...
