Build Error

[David Yak]

Should be simple - I think I have all the pre-reqs.  Ubuntu 20.04 LTS. Thanks for helping. What else do you need to know?

One thing I am happy to try... I have just created a new empty Ubuntu 20.04 LTS server and have not updated or installed anything yet. Is there a recipe for everything that I should install or set up before running the build? Verifications that I can run to make sure the correct library and tool versions are installed?

Hi David,

Building from source will build Crafter CMS v4 (which is what you want to be building and trying out). Crafter CMS v4 requires Java 11 and other prereqs, please see https://docs.craftercms.org/en/4.0/system-administrators/activities/installing-and-verifying-prerequisites.html

Join Slack or Discord for more interactive support from the team/community.

Crafter CMS v4 RC1 will be coming out in the next week or two. The full Crafter CMS v4.0.0 is targeted for GA in Q1 2022.

For building older versions of Crafter CMS, you'll need to checkout the desired branch.
