Re: Using Lua in a C program

[Johannes Hager <hager.j@...>]

If i use your code, i get this:
	hello_world.c:14: error: too many arguments to function `lua_open'

So i  write lua_open() instead of lua_open(0). Than i get this output:
	/usr/local/lib/liblualib.so: undefined reference to `log'
	/usr/local/lib/liblualib.so: undefined reference to `cos'	
	/usr/local/lib/liblualib.so: undefined reference to `sin'
	/usr/local/lib/liblualib.so: undefined reference to `pow'
	/usr/local/lib/liblualib.so: undefined reference to `log10'
	/usr/local/lib/liblualib.so: undefined reference to `exp'
	/usr/local/lib/liblualib.so: undefined reference to `tan'
	/usr/local/lib/liblualib.so: undefined reference to `asin'
	/usr/local/lib/liblualib.so: undefined reference to `acos'
	collect2: ld returned 1 exit status

I have copied the include and lib directories in the same directorie. I did 
"make install". I think their is a problem with that libs. But i dont know 
any solution.
