Mac Ventura GNATCOLL 23 compilation fails

[rogermc2]

Mac OSX 13.0.1 (22A400) XCode Version 14.1 (14B47b) GNAT 12.1.0

Attempts to build GNATCOLL with gnatcoll_23.0.0_29478a20/gnatcoll.gpr fail:

gprbuild -q -c -f -gnatc -u -P/opt/alire/gnatcoll_23.0.0_29478a20/gnatcoll.gpr -XXMLADA_BUILD=static -XLIBRARY_TYPE=static -XGPR_BUILD=static -XGNATCOLL_OS=unix -XGNATCOLL_BUILD_MODE=DEBUG -XBUILD=DEBUG -XGNATCOLL_MADVISE=yes -XGNATCOLL_MMAP=yes process-wrappers.c

Hi @rogermc2

This is most likely and issue with the toolchain and not GNATcoll itself. Can you try to compile with GNAT FSF 12.2?

[rogermc2]

Yes, I've since tried a few other things and get the same error so I'm sure it is an issue with the toolchain and not GNATcoll itself. I'm currently using gnat-x86_64-darwin-12.1.0-2. I'll try and obtain GNAT FSF 12.2. I'm no expert in this area, so a lot of bungling occurs! Also, I've just started trying to use alr so I may be messing things up with that. Thanks for your advice.

I finally located gnat-x86_64-darwin-12.1.0-2. With GPS 2019 the C files compiled OK and I now get as far as:

   [Ada]          gnatcoll-scripts-files.adb

However, GNAT Studio won't open the gnatcoll project but fails with:

[2022-11-18 13:56:03] /opt/alire/gnatcoll_23.0.0_29478a20/gnatcoll.gpr:24:06: imported project file "gpr" not found

I finally located gnat-x86_64-darwin-12.1.0-2. With GPS 2019 the C files compiled OK and I now get as far as:

GNATcoll 23 cannot be compiled with GNAT Community 2019.

This means you have missing dependencies. We recommend to use Alire here. You just have to add gnatcoll to the dependencies of your Alire crate:

alr with gnatcoll

[rogermc2]

GNATcoll 23 cannot be compiled with GNAT Community 2019. Clarification. I wasn't trying to compile with GNAT Community 2019. I was only using GPS 2019 as GUI. The actual compilation was with gnat-x86_64-darwin-12.1.0-2

/opt/alire/gnatcoll_23.0.0_29478a20/gnatcoll.gpr:24:06: imported project file "gpr" not found occurs when trying to build gnatcoll itself.

Perhaps I am not reporting my problem very well?

[Fabien-Chouteau]

Indeed that was not my understanding. But my last comment still holds:
