Lzmq not found by Lua about lzmq

[robotcreator]

Seems like I could resolve the issue by switching Lua to version 5.3.6.
I guess it is a compatibility issue with the newest Lua version (5.4.2), and some functions/symbols were removed from Lua.
This should explain the error message discussed above.

How did you compile lzmq library? I did not test lzmq with Lua 5.4, but I expect it should work. Also, I believe that lua_checkstack stay intact in the Lua 5.4.

I think I installed it via luarocks and moved the .so files manually to /usr/local/lib/lua/5.3. This is included in my cpath, where Lua 5.3.6 looks for modules. This way it worked for Lua 5.3, but not for 5.4...

This should not work for any Lua module written on C (or ny other compiled language)
Lua module have to build against correct Lua version.
If you whant to try lzm wit the Lua5.4 you can download rockspec file an updete version in there. There high chance that it works. Ofcourse you have to have LuaRocks configured for Lua 5.4

Okay, thank your for your assistance so far. I'm happy at the moment, maybe I will try it with 5.4 later again.
