Hi,
Björn added some useful Lua packaging macros in
https://bugzilla.redhat.com/show_bug.cgi?id=1447324
One of them, %lua_requires, adds a dependency on either `lua(abi) =
%{lua_version}` or, on EL6 and below, on lua >= current version and lua
< next version.
Somehow this seems to be automatically applied on Fedora 33 and above
-- without adding any manual require on lua(abi)
e.g. lua-lunitx on Fedora 33
https://bodhi.fedoraproject.org/updates/FEDORA-2020-7c23dc64c0
on Fedora 32, though, the macro is not automatically invoked (so the
update below is bad and I need to redo it)
https://bodhi.fedoraproject.org/updates/FEDORA-2020-9074133de4
In fact, trying to use %lua_requires does not seem to work, with and
without curly braces:
error: line 15: Unknown tag: %lua_requires
error: line 15: Unknown tag: %{lua_requires}
Could someone help explain these two behaviors? I'm working on resuming
the Lua packaging draft so I want to have a canonical example on how
the macros are supposed to be used.
PS Björn -- we should consider moving the macros out of lua-devel and
into lua-rpm-macros, that lua-devel then depends on. That will fix the
inability to get these macros out to EPEL6 and EPEL7 - on those, lua
packages can just BR the macro package directly.
