Recently I got this error: !!! The ebuild selected to satisfy "app-text/xournalpp" has unmet requirements. - app-text/xournalpp-1.1.3-r1::gentoo USE="" ABI_X86="(64)" LUA_SINGLE_TARGET="-lua5-3 -lua5-4" The following REQUIRED_USE flag constraints are unsatisfied: exactly-one-of ( lua_single_target_lua5-3 lua_single_target_lua5-4 ) (dependency required by "@selected" [set]) (dependency required by "@world" [argument]) And I was surprised about me needing to manually set a value for every system I maintain... I think it should be handled as PYTHON_SINGLE_TARGET, that sets a default value that gets updates when maintainers think newer versions are stable enough Thanks
Mmm... it seems it is not like python case as I see many different packages needing a different single target :S In that case maybe each package should default to a preferred lua version using +USE syntax :/
I am pretty sure that DO set the default of LUA_SINGLE_TARGET - to the target which at least at the time of us having done it provided the greatest package coverage, i.e. lua5-1. Welcome to the Lua world, where in spite of having been EOLed upstream ages ago 5.1 simply will not die.
The way targets are set is the same: profiles/base/make.defaults currently contains: PYTHON_TARGETS="python3_10" PYTHON_SINGLE_TARGET="python3_10" LUA_SINGLE_TARGET="lua5-1" LUA_TARGETS="lua5-1"
Some solution might be: 1. Set LUA_SINGLE_TARGET="lua5-4" LUA_TARGETS="lua5-4" in make.defaults. 2. Add appropriate per-package lua_single_target_lua5-1 and/or lua_targets_lua5-1 entries in package.use. Currently the inverse was done, but very incompletely: In profiles/base/package.use: >=app-editors/vis-0.7-r1 lua_single_target_lua5-4 >=sys-cluster/ceph-17.2.0 lua_single_target_lua5-4 >=app-arch/rpm-4.17.0 lua_single_target_lua5-4 media-video/wireplumber lua_single_target_lua5-4 Instead of having ever-growing list of ..._lua5-4 entries, I suggest to have initially bigger, gradually shrinking list of ..._lua5-1 entries in package.use.

I guess then that xournalpp was forgotten there > > Instead of having ever-growing list of ..._lua5-4 entries, I suggest to have > initially bigger, gradually shrinking list of ..._lua5-1 entries in > package.use. Yeah.. if more packages move to newer versions that would make sense :/
