LibreOffice doesn't start (unknown gpu generation)

I'm on Fedora 24 Workstation, 64bit with Cinnamon as window manager.

When I start LibreOffice only the splash screen shows for a few seconds, then it exists without a message. Starting libreoffice from terminal only gives the message unknown GPU generation.

My GPU is:

$ inxi -G
Graphics:  Card: Intel HD Graphics 530
           Display Server: Fedora 118.4 driver: intel Resolution: 1920x1080@60.02hz
           GLX Renderer: Mesa DRI Intel HD Graphics 530 (Skylake GT2) GLX Version: 3.0 Mesa 12.0.3

There is a error report generated but I cannot report it because of "some locally built software" probably in /home or /usr/local. Can I somehow check which files are crashing? Running as root doesn't help (only other user on system), the same error appears, so I don't think it's something in /home.

Can you be more specific about the locally built software? Have you installed anything to /usr/local? That GPU message appears to come from Mesa, but it's not clear if it's a fatal error or not. I found a nearly identical question on the libreoffice site where the person (you?) mentioned that they had Oracle Java installed. If that was you, then can you try without it? Also, try run glxgears in a terminal window to see if you get the same message.

Yes, I posted there as well. When I set the java-version to OpenJDK with update-alternatives, I get the same error. glxgears runs without any error, I don't recognize another error, only libreoffice doesn't start. I cannot explain more about the locally built software, that is everything the error reporting tool tells me.

I fixed the problem by dnf remove pocl. Apparently LibreOffice has a problem with OpenCL.
