I tried to build something with GnatColl from GPS Community 2021 on Fedora 35. The linker failed, saying
ld: /home/cantanima/common/Ada/Quoter/obj/gnatcoll-refcount.o: in function `gnatcoll__refcount__sync_bool_compare_and_swap':
gnatcoll-refcount.adb:(.text+0x622): undefined reference to `gnatcoll_sync_bool_compare_and_swap_access'
collect2: error: ld returned 1 exit status
I can fix this from the command line by copying the failed command and adding ~/opt/GNAT/2021/include/gnatcoll/gnatcoll_support.c to the list of things to compile, as that's the included file with the desired function. That's awfully inconvenient, though.
I guess I have something configured slightly wrong. Might anyone here have an idea?
