[PD-dev] Current GIT master builds are unable to load Gem on Windows

[Lucas Cordiviola]

I'm starting pd with

pd -noprefs -font 12 -path C:\Users\Lucarda\Documents\Pd\externals\Gem 
-lib Gem

I get the warning in the console:


*******************

GEM: Graphics Environment for Multimedia
GEM: ver: 0.93.
GEM: compiled  on Mar 24 2018
GEM: maintained by IOhannes m zmoelnig
GEM: Authors :    Mark Danks (original version)

GEM:     mailing-list https://lists.puredata.info/listinfo/gem-dev/


---> GEM: please manually add Gem path 
'C:/Users/Lucarda/Documents/Pd/externals/Gem' to Pd's search path


GEM: compiled for MMX architecture
GEM: using MMX optimization
GEM: detected 4 CPUs
GEM: image loading support: SGI
GEM: image saving support: SGI


***************

But when I go to add it is already there because of the  "-path 
C:\Users\Lucarda\Documents\Pd\externals\Gem"

On the mail below there is output from the config:

default window         : gemw32window
