It seems `gdb-16.2` doesn't built with `babeltrace-2.0.5`, `babeltrace-1.5.11` still works. When having `babeltrace-2.0.5` installed the `gdb` build fails at the point where it tries to configure `gdb` itself - after having finished building `gdbserver`: make[2]: Leaving directory '/home/share/gentoo/var/tmp/portage/dev-debug/gdb-16.2-r2/work/gdb-16.2/gdbserver' make[1]: Entering directory '/home/share/gentoo/var/tmp/portage/dev-debug/gdb-16.2-r2/work/gdb-16.2' Configuring in ./gdb configure: loading site script /home/share/gentoo/usr/share/config.site configure: loading site script /home/share/gentoo/usr/share/config.site.d/80crossdev.conf configure: creating cache ./config.cache checking whether to enable maintainer-specific portions of Makefiles... no checking for x86_64-pc-linux-gnu-gcc... x86_64-pc-linux-gnu-gcc checking whether the C compiler works... yes checking for C compiler default output file name... a.out checking for suffix of executables... .. checking whether to use babeltrace... yes checking for libbabeltrace... no configure: error: babeltrace is missing or unusable make[1]: *** [Makefile:10313: configure-gdb] Error 1 make[1]: Leaving directory '/home/share/gentoo/var/tmp/portage/dev-debug/gdb-16.2-r2/work/gdb-16.2' make: *** [Makefile:1028: all] Error 2 Looking into `config.log` for this run I see: configure:33093: checking whether to use babeltrace configure:33095: result: yes configure:33535: checking for libbabeltrace configure:33565: x86_64-pc-linux-gnu-gcc -o conftest -O2 -pipe -O3 -pipe -march=tigerlake -mtune=tigerlake -Werror -Wl,-O1 -Wl,--as-needed conftest.c -ltinfow -lncursesw -lm -lbabeltrace -lbabeltrace-ctf >&5 conftest.c:214:10: fatal error: babeltrace/babeltrace.h: No such file or directory 214 | #include <babeltrace/babeltrace.h> | ^~~~~~~~~~~~~~~~~~~~~~~~~ compilation terminated. configure:33565: $? = 1 configure: failed program was: You see it tries to include `babeltrace/babeltrace.h` in this test; but `babeltrace-2.0.5` doesn't ship that anymore (supposedly because it's incompatible with the old 1.0 API): $ q qlist babeltrace | grep 'babeltrace\.h' /home/share/gentoo/usr/include/babeltrace2/babeltrace.h Manually masking `=dev-util/babeltrace-2.0` works. It'll pull in the older `babeltrace-1.5.11` and `gdb` builds again. Reproducible: Always
