.so location dependent error - OSX, lua 5.1w4

[jym@...]

Hi,

[Duped on the IcyNorth forum, but no response there - apologies]

I am using Lua 5.1(work4) on OSX 10.2.8 to load c modules using code thus:

LUA_PATH="./foo/temp1/?.so" -- as appropriate
foo = require("testcomp")
foo.hello()

I will post the module code if required, but the module loads and works 
correctly if the .so is in the current working directory (the same 
directory where the above loading code is run from), but not if it is 
elsewhere, complaining of:

lua: test.lua:2: error loading package `testcomp' 
(./foo/temp1/testcomp.so:1: unexpected symbol near `?') [that's an inverse 
video ?]

A component built in another dirctory, then moved to the current working 
directory does works. Building command for components is:

g++ -noprebind -shared -bundle -o foo/temp1/testcomp.so -I./include/ 
-L./lib/ -llua -llualib foo/temp1/testcomp.cpp

Im am using gcc v.3.4.3

I'm assuming its a missing compiler flag I need, as lua components do not 
have this problem; possibly the compiler doing something freaky with names? 
(all relevent methods have extern C linkage)

Any thoughts?

Cheers,
j
