actually my issue from earlier today waas something else (some improper locking)
I did have issues on debian 11 with the latest clang version. Going with the one which comes with the box was ok but the one from llvm.org repo gave me issues. I remember I had to compile things twice. The first attempt failed miserably. make check or make test will go nuts... So its maybe a issue between libobjc2 and libdispatch and gnustep-base. that they circulalry depend on each other and fail when libobjc 1.0 is first referred. Or I simply didnt had my environment variables set properly on my first attempt. I cant figure it out but I have seen similar issues with Debian10 when built for the first time on a empty machine. Debian rule #1 is to ALWAY use the gold linker. I usually do this by a symlink: cd /usr/bin mv ld ld.old ln -s ld.gold ld (ld originally points to x86_64-linux-gnu-ld instead of x86_64-linux-gnu-ld.gold ) Debian rule #2 is to always use clang (version 8 or newer) If you dont use the gold version and/or clang version 7 or older. you will see failures due to misaligned datastructures (it optimized things away it shoudlnt)). Thats a quite late failure which will bite you very hard and makes your head twist. Because it looks like it "kinda" works but then does all kinds of strange arbitrary things. Properties return data from other places than they shuld and you get rubbish data etc. my debian11 binaries where built with Debian clang version 11.0.1-2 my debian 10 binaries where built with Debian clang version 10.0.1-++20210313014605+ef32c611aa21-1~exp1~20210313125208.190 these are the packages I have built for Debian11 (x86-64) gnustep-base-1.28.0_amd64.deb gnustep-corebase-0.2.1_amd64.deb gnustep-make-2.9.0_amd64.deb libdispatch-5.5.0_amd64.deb libiconv-1.16.0_amd64.deb libobjc2-2.1.0_amd64.deb You can download them from: http://repo.universalss7.com/debian/dists/bullseye/universalss7/binary-amd64/ the way I have built these is documented here: https://github.com/andreasfink/ulib/blob/master/doc/README-Debian11-bullseye.txt I didnt get to the gui & back part because I dont need them for my apps. Generally if gnustep-base tests passes, then the rest is a piece of cake. the GUI part originally gave me an issue in Debian 11. Can't remember what it was.
