Re: Adding new paths for the access of embedded programs

["Luciano de Souza" <luchyanus@...>]

I can't understand why, but unfortunately it didn't work. Let me show you 
the first lines of my script. In c:\arquivos de programas\iup are the DLL 
for IUP. Therefore, the program should be successfu in accesssing the 
libraries from another folder called c:\test where I have only the 
executable that fires the program and the script Lua calling the DLLs.

require('package')

path = 'c:\arquivos de programas\iup"

if not string.find(package.path, path, 0, true) then

package.path = string.format("%s/?.lua;%s", path, package.path)

package.path = string.format("%s/?/init.lua;%s", path, package.path)

package.cpath = string.format("%s/?.dll;%s", path, package.cpath)

end

require('iuplua')

require('iupluacontrols')
