I don't know if https://www.physicsforums.com/showpost.php?p=1241966&postcount=5" will help.Aether, I am exactly at that point where I figured I had to put the maple.ini file in the LIB directory so it works but Maple complains it can't find basislib.m although it's there.
Have you found a solution for basislib.m?
You have to use the maple.ini file they are talking about because it contains commands to load all the libraries at startup. The ini file that comes with the GRTensor package loads only the library with the main commands grii.m.With Maple 8 and 9, for the current release of GRTensorII, you need to load the libraries needed for your calculation. In previous versions of Maple they autoload. A typical initialization file is here. Simply download this file and follow the instructions in it. If you have developed your own libraries, load them in the same way.
