trying pygcam with GCAM6: error while init confg file

[amnmalik]

Hi Richard,
I know the readme file says that you haven't tested pygcam with GCAM 6.0 but I thought to have a go at it anyway. I successfully installed pygcam as explained nicely in your docs, however when I try to initialize the configuration file, I get the following error:

Error: A JNI error has occurred, please check your installation and try again

Could you help in addressing this issue? Thanks in advance!

It looks like the class path is looking in C:/Users/Aman/GCAM/gcam-v5.1.3 rather than in the 6.0 directory. Did you use the command-line argument -g / --gcamDir on the "init" command to set the location of the 6.0 distribution?
