Hi all,
I compiled Vim with Lua support and am quite happy now that I can
write Vim procedures in my favourite language. Most things work, but
there is one problem I couldn't solve. Whenever I try to require a
module (after setting package.path and package.cpath right), I get an
error message like this:

  error loading module 'posix_c' from file '/usr/lib/lua/5.2/':
  /usr/lib/lua/5.2/ undefined symbol: lua_gettop

It seems that Lua has found the required module, but the module can't
access liblua.a. No idea why. Posix is just an example, the same
happens with other modules as well.

Any ideas what could be the reason and how to get around this?

How are you "setting package.path and package.cpath right"?

My vimrc starts with

lua << EOF
package.path = "/local/bernd/lui/?.lua;./?.lua;/local/bernd/lua/lib/?.lua;/usr/lib/lua/5.2/?.lua;/usr/share/lua/5.2/?.lua"

This is the path I use in standalone programs, where everything works fine.

Chances are
that you built Vim against Lua 5.1, and you're asking it to load 5.2
modules, which it gets upset about.

Certainly not, the only Lua I have is 5.2.
