I am trying to compile the latest OF version from Github using the master branch and getting following error:
openFrameworks/libs/openFrameworks/utils/ofConstants.h:288:24: fatal error: tesselator.h: No such file or directory
This file does not exist anymore and it seems it has been replaced by ofTessellator.h. I don’t know how to handle that error otherwise I would have created a PR. Sorry for that.
Very kind regards,
Hans 
Hi, just checking what exact steps have you followed? what platform, IDE are you using?
Did you read and followed the steps on INSTALL_FROM_GITHUB.md?
On windows, I was able to download from github, run download_libs.ps1, then using a downloaded PG compile and run examples without any problem.
Best,
Hi Jordi, thanks for your reply. I was installing on Ubuntu. But as it seems my version is too new. I am running version 17 whereas version 14 is pretty well supported. I tried a lot, like chaning gcc versions and manual compilation of RtAudio and other stuff. There is always something failing. So I think I better switch to my Windows 10 box and give up on Linux & OF.
Thanks,
Hans
i think you are just missing downloading the external dependencies. follow the install from github guide, everything is in there. it should work fine with ubuntu 17.04 without any modification
Hi Arturo,
thanks for keeping up my hopes.

II.) Scripts
III.) Comments
1.) The handish Emacs stuff is possibly PR material.
2.) Maybe we should set up several CI jobs for Linux taking into account the different versions.
3.) I am not sure whether the gles example project should be left out for Ubuntu. Looks like Raspberry Pi stuff to me.
IV.) Failed example project
One example did not compile. Not exaclty sure why. Template looks fine to me by just skimming over it. I deleted it. All other projects compiled nicely. Some warnings though every now and then.

Sorry, posting is a bit longish.

Hi Arturo,
I also deactivated Anaconda Python. It seems to have caused some problems too.
Kind regards,
Hans-J.
thanks for the detailed report, it seems there’s a bug with that one example, surely related to the recent change to glm as vector math library, i’ll take a look
The gles project also had compiler errors. I do not know if it is supposed to be compiled on Ubuntu or just on the Raspberry Pi. I just decided to comment it out in the buildAllExamples.sh script.
yes the gles example is only for gles platforms, right now, only arm linux boards
Hello,
You said to block the compilation of gles?
How did you proceed because under my Ubuntu Studio 18.04, it blocks me on this example.
I followed your procedure a little higher, but I think you forgot to write something about Gles.
Can you tell me what?
Thank you in advance for your answer.
Regards,
