Re: Undefined symbol: Lua_insert in core.so

["Julio José Mora Salido" <jmorasali@...>]

Hi,

I couldn't solve the problem. I changed the Makefile as follows:

# makefile for building Lua
# see ../INSTALL for installation instructions
# see ../Makefile and luaconf.h for further customization

# == CHANGE THE SETTINGS BELOW TO SUIT YOUR ENVIRONMENT =======================

# Your platform. See PLATS for possible values.
PLAT= none

MYCFLAGS=
MYLDFLAGS=
MYLIBS=

# == END OF USER SETTINGS. NO NEED TO CHANGE ANYTHING BELOW THIS LINE =========

I think the symbols are exported correctly. However, when I check the symbols in the shared library 
socket.so.2.0.2, lua_insert is declared as "Undefined". Now I'm completely lost. Any help would be appreciate.

Thanks
