Hello,

I’ve been using Webclipse from Ubuntu 16.04 and then I transitioned to CodeMix a couple of months ago on Ubuntu 18.04, everything seem to work ok, but now I’m having trouble with the engine.
At first I was getting some JDK errors on Eclipse because of a couple glyphs or something like that but I switched from openjdk-8-jdk to oracle-8-jdk, and that seemed to calm it down.
Next problem I ran into a problem when I installed CodeMix using the Eclipse Marketplace, then after restarting I got the error:

Process output:
/home/<user>/.codemix/engine/codemix-engine: error while loading shared libraries: libgconf-2.so.4: cannot open shared object file: No such file or directory

I was able to solve it by installing the lib with the command:
sudo apt install libgconf-2-4

After I got that error out of the way, I hit a wall at this one:

Exit value: 139

Process output:

And yea, not getting any output which is strange.
I wanted to get my hands dirty and check some logs, but I was able to search only this log:

$ cat ~/eclipse-workspace/.metadata/.log

I guess this is why it’s stuck with the message “CodeMix Engine is starting up”.

I get the same errors on Spring Tools 4, which is also Eclipse based.
I also tested on Ubuntu 18.10, same result.

If anyone can point me to the right logs, I’ll be glad to post them.

Thank you,
Peter

@petre-rosioru, I’m sorry you are running into this issue. CodeMix should run without issues in Ubuntu. You can turn on a more detailed log for us by editing your eclipse.ini and adding this line after -vmargs:
-Dcom.genuitec.eclipse.engine.log=true

A log file will be generated at your <user home>/.codemix/codemix-<date>. Can you share to us that file?

Thanks!
Aaron Lara

PS: Since it’s weekend we might not be able to respond to your messages until Monday. Thanks for your comprehension.

[petre-rosioru]

TBH, I wasn’t expecting for you guys to respond this early, especially in the weekend, so thank you in advance.
Unfortunately, logs are no different from what I displayed before:

Important:
I am running Ubuntu 18.10 in a virtual machine with VMware Workstation Player version 15.0.0 build-10134415. I don’t actually know if this might be a problem, but I felt that it’s important to mention.

Thank you,

Peter,

Thank you for sharing the log and the details.

Can you please try starting the CodeMix engine outside of Eclipse/STS and share with us the output? Open the command prompt and run ~/.codemix/engine/bin/codemix-engine.

There seems to be a known problem on Ubuntu 18.10 due to the libc6 package version (2.28) that is also causing VSCode fail to launch. (https://github.com/Microsoft/vscode/issues/51917).

As a workaround, while we investigate a possible fix, you can try downgrading libc6 to version libc6.2.27-3ubuntu1 and see if it helps. You can try either:

sudo apt-get install libc6=2.27-3ubuntu1
or
sudo aptitude install libc6=2.27-3ubuntu1

Please let us know if the workaround helps.

Hello @support-swapna,

I’ve ran the codemix engine, like you said, here is the log:

petre@ubuntu:~/.codemix/engine/bin$ ./codemix-engine 
./codemix-engine: line 35: 14278 Segmentation fault      (core dumped) ELECTRON_RUN_AS_NODE=1 "$ELECTRON" "$CLI" "$@"

I tried reinstalling to the libc6=2.27-3ubuntu1 but apparently it’s not registered in the Cosmic Cuttlefish repo, si I tried downloading libc6 from https://ubuntu.pkgs.org/18.04/ubuntu-main-amd64/libc6_2.27-3ubuntu1_amd64.deb.html but it’s not resolving dependencies, because I get the following error:
/lib/x86_64-linux-gnu/libc.so.6: versionGLIBC_2.28′ not found (required by /lib/x86_64-linux-gnu/libudev.so.1)`

I tried reverting to the Bionic Beaver sources.list to see if I can pull something, but no luck:

$ sudo apt-get install -f libc6=2.27-3ubuntu1

Some packages could not be installed. This may mean that you have

The following information may help to resolve the situation:

The following packages have unmet dependencies:
 libcups2 : Depends: libavahi-client3 (>= 0.6.16) but it is not going to be installed
 libgl1 : Depends: libglx0 (= 1.1.0-1) but it is not going to be installed
 util-linux : PreDepends: libsystemd0 but it is not going to be installed
              PreDepends: libudev1 (>= 183) but it is not going to be installed
E: Error, pkgProblemResolver::Resolve generated breaks, this may be caused by held packages.

I could have tried to solve the dependencies, but because I am really tired, I had to give up.
At the end of the day, I get it, it’s a vscode bug, but I installed vscode and seems to be working fine.
To be honest, I’m not sure what to say at this point.

Thank you,
Peter

Hello Peter,

We appreciate your effort on applying the suggestions and providing the output you are getting. As you are aware our engine is having a problem with the version of the libc6 package shipped on Ubuntu 18.10, however, on Ubuntu 18.04 should be working fine based on our tests. If you are in need to use 18.10, you need to downgrade to libc6=2.27-3ubuntu1. We found that using aptitude cmd the downgrade performs smoother, can you please try using aptitude cmd? This will show the list of additional packages that will be downgraded, but, after completion you will be ready to go.

And yes, as you mention you need ‘Bionic Beaver’ sources.list, just make sure ‘Cosmic Cuttlefish’ is not enabled.

Best Regards,
Hugo Herrera

Hello @jhugohr,

I’ll give it a try but now I’m having problems at work because I get the error for multiple systems activated on my account. Of course, this does not stop me from running the command but I need to get a new machine up and running because I’ve been experimenting more stuff on 18.10 and I ended up deleting it because I wanted to start from scratch.
I’ll send an email sales@genuitec.com to reset my systems, get a new machine up and running, and get back at you with some results.

Thank you,
Peter

Hi @petre-rosioru, We will contact you privatly since it includes information about your license.

exactly same problem here.
Anyway, you noticed “…due to the libc6 package version (2.28) that is also causing VSCode fail to launch…” however my VSCode launches and runs without issue…
Concerning downgrading libc6 here is the result:

sudo apt install libc6=2.27-3ubuntu1
Reading package lists… Done
Building dependency tree
Reading state information… Done
E: Version ‘2.27-3ubuntu1’ for ‘libc6’ was not found

Hey,

Thanks for reporting this, you are right this looks like an odd issue, the thing is that our CodeMix Engine is not running with the latest version of the OSS VSCode yet, right now we are working on that and this will get fixed in a near future, once we get to upgrade the base Engine version, mean while the only workaround we know about is to downgrade the libc6 library, it is not the best approach but it will get you up and running. Hopefully we’ll get the upgrade soon enough.

Best Regards
Ignacio

Hey,

We have updated Electron to a more recent version in Codemix 2018.12.13 which fixes the “CodeMix Engine Process has ended unexpectedly” error in Ubuntu and has improved handling of missing libraries.

Cheers,
Sal
