Hi Marisa,

I assume that you try to compile the 'master' branch of Paul's Einstein 
GitHub archive. The master branch is occasionally updated by Paul. I am 
not sure if he tests the Linux build regularly. His main platform is 
Apple IIRC.

I branched quite a while ago, so GitHub has a new branch called 
'matt2020' which uses FLTK as the cross-platform user interface library, 
removing most of the platform specific code from Einstein.

Unfortunately, both branches are quite different now, and I was not able 
to merge them back. On the good side, I do build the MSWindows, Apple, 
and Linux version quite regularly. Build instructions should be quite 


The current HEAD has not been tested on Linux yet, but should compile. 
The v2020.4.7 tag is the latest official release for all platforms and 
should compile using those instructions. I will release v20202.4.11 for 
all platforms probably next weekend.

No information on Android or iOS at this point, sorry.
