Error when installing using luarocks using Lua 5.4.0

[leonsal]

Hi,

Luarocks reports the following error when installing using lua 5.4.0:
error "unsupported Lua version (i.e. not Lua 5.1, 5.2, or 5.3)

Any estimate when compatibility with lua 5.4.0 will be implemented ?
Regards.

I think your specific error is due to an older Luarocks version, though, since our rockspec specifies >= 5.1, which should include 5.4. Updating your Luarocks might fix this error, but I'm not sure if Luv works properly with 5.4 yet.

I also have this problem (and am using most recent luarocks). The error pops up after it looks like luv finished building. Any known workaround? I tried running the command in #515:

LUA_DIR=/path/to/lua-5.4.0/src cmake .. -DWITH_LUA_ENGINE=Lua -DLUA_BUILD_TYPE=System

But it seems to ignore my LUA_DIR and just finds my lua-5.3.5 installation in /usr/local. Note that my lua-5.4 is elsewhere, I'm on MacOS and the /usr/local luas come from homebrew, which doesn't yet include lua 5.4 (I have lua 5.4 through asdf. I'm not very skilled in building/cmake etc so I could be missing something obvious (but I did replace "/path/to/lua-5.4.0" with path to my asdf installation, also tried with a direct clone of the lua repo from here, neither worked).

EDIT: Nevermind, it was indeed a dumb error on my part. Was able to build from source using squeek502's instructions.

Lua 5.4 support should be fixed in the latest versions. Please re-open if there is still an issue.
