Does not build on raspbian

[Nomarian]

It seems luapath is not capable of identifying where lua.h is on raspbian using luarocks.

FWIW, lua.h is in /usr/include/lua5.3/

; sudo luarocks install cqueues

This suggests luapath is not chmod +x. Do you happen to have /tmp mounted noexec?

[Nomarian]

ah, I do.

FWIW I happen to have $TMPDIR set which usually avoids this.

FWIW I happen to have $TMPDIR set which usually avoids this.

I guess that would be a luarocks bug rather than a cqueues/luapath bug if TMPDIR is not being respected?

[Nomarian]

Ah, I was mistaken, when you sudo the environment variables does not get inherited, you have to sudo -E.

other environments do have /tmp as noexec and you can sh /tmp/ instead of running directly. but sudo -E worked, so matter closed?

I have seen luapath in other places, I think it should just be installed via luarocks into its bin path considering.

[daurnimator]

I don't think there's anything that can/should be done in the context of the cqueues project
