rockspec for Lua 5.3: LUA_COMPAT_APIINTCASTS about lua-mosquitto

[karlp]

I've pushed a 0.4.1-2 which adds this define, can you verify that it works for you?

[jimt]

Yes, I was able to compile/install on a fresh Ubuntu 20.04 installation. Thank you for the quick resolution to my problem.

[karlp]

maybe? Could you elaborate further on how it fails for you?

karlp@strem:~/src (master *)$ luarocks53 install lua-mosquitto

Is this exposing differences in system lua configurations?

[karlp]

Looks like my fedora32 at least has #define LUA_COMPAT_5_2 enabled, which enables COMPAT_APIINTCASTS? Is that not default?

[jimt]

On Ubuntu 20.04.2 it isn't the default. I stuck variables.CC = "gcc -DLUA_COMPAT_APIINTCASTS" in my /etc/luarocks/config.lua so that I could install, but I was guessing it made more sense in the package's rockspec.
