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 
current:

https://github.com/pguyot/Einstein/blob/matt2020/BUILDING.md

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.
