[vim/vim] Lua interface broken after Lua 5.5 upgrade (on Linux) (Issue #19814)
Lyderic Landry
lyderic created an issue (vim/vim#19814)Steps to reproduce
This issue was reported in #19639 and reported as fixed in #19658 on MacOS. However, with or without the Claude fix, it still doesn't work for me on Linux.
- I compiled vim from the latest master as of 2026-03-25 05:00:00 UTC (b435da0) with the following ./configure:
./configure --with-features=huge --enable-luainterp=dynamic --enable-fail-if-missing
-
Compiled without error
-
Opened vim
-
In command mode, entered:
:lua print("hello world") -
Got this error:
E448: Could not load library function luaL_openlibs
Lua library cannot be loaded.
Expected behaviour
:lua print("hello world") should print "hello world" to the command line. It used to work before the upgrade to lua 5.5.

lyderic left a comment (vim/vim#19814)I submitted the problem to OpenCode Zen: the problem is that Lua 5.5 renamed the function luaL_openlibs to luaL_openselectedlibs.
if_lua.c needs to be patched to be able to handle both function names. I will submit a PR with a patch.
