Operating system: Linux 4.15.0-50-generic #54-Ubuntu SMP Mon May 6 18:46:08 UTC 2019 Slicer version: Slicer-4.10.2-linux-amd64 This problem occurs when I try to open the extension manager by clicking the button “Install Slicer Extensions” Expected behavior: Be able to browse and install extension…

@pieper Does setting SLICER_OPENGL_PROFILE to compatibility make the core profile warning disappear for you? [image] PaoloZaffino: Same problem here (Arch linux) Do you mean that you have OpenGL core profile warning on application startup, or extension manager crash (potentially due to incom…

[image] lassoan: Does setting SLICER_OPENGL_PROFILE to compatibility make the core profile warning disappear for you? No difference. I also tried the no and core options but always get the same result. (Something else is odd today with those Operation canceled messages, but they also appear…

[image] pieper: I also tried the no and core options but always get the same result. Selection of profile was introduced after 4.10.2. Could you try with a recent nightly? [image] pieper: Something else is odd today with those Operation canceled messages I often get those on Windows, …

Same result with the current nightly, the environment variable has no effect. Oddly my local (debug) build on the same linux system doesn’t have the error message. Extension manager dialog works for all combinations.

[image] pieper: Same result with the current nightly, the environment variable has no effect. Is the reported profile changing in the application log? There should be a log line like this: Qt configuration .........: version 5.10.1, with SSL, requested OpenGL 3.2 (compatibility profile) If …

Yes, the log shows the environment variable worked. [DEBUG][Qt] 16.07.2019 16:15:19 [] (unknown:0) - Qt configuration .........: version 5.11.2, with SSL, requested OpenGL 3.2 (compatibility profile)

For this log entry, we check value in QSurfaceFormat::defaultFormat(), so it really is the surface format that Slicer uses. Maybe the log entry is generated by the webengine process. What Qt version do you use in your local build that does not generate the error? This error seems to be very common …

My local build is 5.8.0. Maybe too old for the problem.

I have the same issue with Slicer-4.10.2-linux-amd64 . When I try to launch the ExtensionManager, Slicer crashes: $ ./Slicer Switch to module: "Welcome" An OpenGL Core Profile was requested, but it is not supported on the current platform. Falling back to a non-Core profile. Note that this might ca…

Question, is there a way to install extensions without using Extension Manager on the GUI? @lassoan @pieper Obviously building Slicer is an option, but not the most preferred one on ERIS cluster nodes with no sudo access.
