Base lua gpio binding vs. pkgsrc lua extensions like lua-socket

[Martin Mersberger <gremlin%portal-to-web.de@localhost>]

Good afternoon,

I'm playing around with my RPI running current and the gpio binding.
Using the base lua(1), the gpio binding works really fine, but I also
like to use the pkgsrc lua-socket extension. By default, the pkg has
pkgsrc/lang/lua* as dependency and also installs into /usr/pkg.

How would I stick it together to have a lua(1) environment having both,
gpio binding and the socket extension? I've tried to adjust LUA_PATH and
LUA_CPATH to make lua able to find the extensions, but it seems to have
some incompatibilities:

/usr/bin/lua: error loading module 'socket.core' from file
'/usr/pkg/lib/lua/5.3/socket/core.so':
    /usr/pkg/lib/lua/5.3/socket/core.so: Undefined PLT symbol
"luaL_checkint" (symnum = 49)


Any ideas?


Many thanks!

cheers
