Can't load in KUbuntu 20.04 installation #244

Closed v1993 closed 4 years ago

v1993 commented 4 years ago

I'm trying to get lgi to work on my new installation (git lgi built with luarocks make. It fails to load module with following message:

error loading module 'lgi.corelgilua51' from file '/home/v/.luarocks/lib/lua/5.3/lgi/corelgilua51.so':
    libffi.so.6: cannot open shared object file: No such file or directory
stack traceback:
    [C]: in ?
    [C]: in function 'require'
    /home/v/.luarocks/share/lua/5.3/lgi/core.lua:14: in main chunk
    [C]: in function 'require'
    /home/v/.luarocks/share/lua/5.3/lgi/init.lua:19: in main chunk

    [C]: in function 'require'
    stdin:1: in main chunk
    [C]: in ?

And it is unsurprising because it is libffi.so.7 now!

Well... but since the .so files depends on libffi.so.6, somehow you managed to compile it against it. Or does luarocks now distribute pre-built binaries?

Anyway, this is fixed by simply recompiling lgi. The linker should do The Right Thing (tm) when it turns its -lffi argument into the name of a shared object.

I made a fresh build I think? Will try with clean repo this time anyways.

Weird thing is that while luarocks make builds git version actually it still fails. I also have no libffi.so.6 installed.

Alright, this fixed the problem. Closing issue.
