Re: installing Lua 5.1 on AIX 5.2

[mfmorss@...]

I must apologize for my ignorance; the lack of recognition of lua_pushnil
was due to my failure to provide a link to the liblua.a.  I am not root on
this machine, and I have lua installed in a nonstandard directory.
However, when I corrected this, there was still a problem.

Once again with ../lua5.1/src as the current directory, I issued:

cc -bnoquiet -I/mydirectory/include -L/mydirectory/lib -llua -o dummy.so
-qmkshrobj dummy.c

and this failed with problems in the pow and floor functions, viz:

I rather suspect that I still have a problem with my call to cc; but I am
not sure what it is.

This means that lua_pushnil is not being exported from the lua executable.
Under gcc, in several platforms, the magic to make this happen is to add
-Wl,-E when building the standalone interpreter. I don't know how to do
this with xlc, sorry. Any AIX and xlc experts around?
