Thingworx 9.2.5: Failed to load FlxCore

[realndh]

Hi all

I got the following error while installing thingworx on ubuntu-linux-20-04-desktop aarch64.

Can I install Thingwork on the arch64 CPU?

Sometimes this happens because the Java Home reference is incorrect.

I think they want you to point to the JDK vs. the JRE although I don't really do much with Linux so I am not sure if that is the same or different.

Also make sure the java options are correctly set for tomcat

Hi @realndh.

Did you find a solution to your problem?  Please let me know so I can follow up with our R&D team on the possibility that the issue is related to the processor.

Regards.

I'm running into the same issue and in my case I am trying to build a docker container to run on macOS with the Apple M1 architecture (aarch64).  I can build the containers (including Postgres, Postgres-init, and security) but when running the platform container it will fail trying to load the file listed in the OP.  Usually the docker containers are amd64 and the linker will use that file just fine which is appropriate for that architecture but since this is aarch64 it fails to load.  I'm guessing a special build of the flex library using that architecture will be required to solve this.

Hi @rattmice.

We are pursuing this with R&D.  Once we have more information, I will post it here.

Bumping this post to see if any updates have been made in the last year.

Hi @rattmice.

Unfortunately, this is not a supported configuration and there are no plans to add it.

Thank you, Sharon.  After some hacking I was able to generate docker images for ThingWorx 9.4.2 on Mac Silicon that work around the architecture issue.
