RPM 4.20.0 building problem

[iseki0]

When I trying to build following the INSTALL file, a linking problem blocks me.
I'm tried modify the CMakeLists.txt tools/CMakeLists.txt, but it doesn't works.

My commands:

mkdir _build
cd _build
cmake  .. -DLUA_LIBRARIES=/root/lua-5.4.7/src/liblua.a -DLUA_INCLUDE_DIR=../../lua-5.4.7/src -DWITH_SEQUOIA=OFF -DWITH_LEGACY_OPENPGP=ON
make

The lua was compiled with a flag -fPIC(I put it to the Makefile).

My problem:

Before I post here, I tried to add target_link_libraries(elfdeps PRIVATE m) and target_link_options(elfdeps PRIVATE "LINKER:--copy-dt-needed-entries"). But it doesn't works.

It's librpmio that's missing linkage to libm, elfdeps is just the messenger. Now, librpmio itself doesn't need libm for anything, it's Lua that does, and you seem to be statically linking it:

-DLUA_LIBRARIES=/root/lua-5.4.7/src/liblua.a

We don't generally endorse or support static linkage because it's nothing but a headache. As you're witnessing here. It might work if you add -libm to librpmio linked libraries but it's equally possible there are further issues.

That /root/... path also suggests you're building as root which you absolutely should not be doing, for any software.

We don't generally endorse or support static linkage because it's nothing but a headache.

But I read the docs of lua.org, there's no guide about compile lua to a dynamic library.

[pmatilai]

All the distros build it as a dynamic library. It should also be available on Ubuntu, so you don't need to roll your own.
