Hi,
On my newly upgraded Fedora 41->42 beta desktop I'm seeing the link
error:

where the interesting bit is:
-Wl,--start-group -L/usr/lib64/pkgconfig/../../lib64 -ldbus-1 -L$W/UnpackedTarball/icu/source/lib -licui18n -L$W/UnpackedTarball/icu/source/lib -licuuc -L$W/UnpackedTarball/curl/lib/.libs -lcurl -Wl,--end-group
so we've got -L/usr/lib64/pkgconfig/../../lib64 before -L$W/UnpackedTarball/icu/source/lib
nd /usr/lib64/libicuuc.so points to the .76.1 version
that is indeed a problem, it is obfuscated -L/usr/lib64 and that should
never be explicitly on the link command as it will cause exactly this
kind of problem
we already try to filter it in configure.ac:
case "$f" in
# let's start with Fedora's paths for now
-L/lib|-L/lib/|-L/lib64|-L/lib64/|-L/usr/lib|-L/usr/lib/|-L/usr/lib64|-L/usr/lib64/)
# ignore it: on UNIXoids it is searched by default anyway
# but if it's given explicitly then it may override other paths
# (on macOS it would be an error to use it instead of SDK)
;;
but it was cunningly obfuscated so the filtering doesn't work for you.
you can try to search in config_host.mk which system library is responsible.
imho it's a bug in the packageconfig file of that system library, these
should never contain system paths that are searched by default anyway.
