How to build Blender 2.93 alpha on Ubuntu 18.04?

Support Technical Support
#1

Hi! I tried: git checkout blender-v2.93, git checkout blender-v2.93-master and terminal said that branch isn’t exist. Previously this way was works for me on 2.83, 2.90 versions. How actually I can learn valide name of unreleased branch like this one and compile it?

Btwn, for Ubuntu 18.04 I need gcc v9 - I know that.

#2

Hi.
git checkout master

Development version does not have its own branch until it is in release candidate state. So it lives in master branch.

To see available branches:
git branch -r

To search with keyword in available branches:
git branch -r | grep -i KEYWORD_HERE

Edit:
Just in case you are not aware of this. Official builds are portable builds, you don’t need to compile and it should work by extracting the file to a new folder and running “blender” file there:

Thank you! But I stumble on error after compilation

Maybe you know why is this happen?

#4

Yeah, I know that) But I wanted automate it as much as possible and I don’t wanna to download and delete archive every time. Just simple sh script to automate it. But with new versions of Blender I stumbled with many issues - I was upgrade python and gcc for that case and still receive errors…

I’m not sure if you are using precompiled libraries build method, which is recommended (blender manual instructions). I recommend that if you don’t find the solution by googling with the error message that you get, you ask the question here:
