Hi Miguel,

I don't know if it is the same thing as virtual box, but use on a virtual machine is not supported. See "System Requirements": https://www.rbvi.ucsf.edu/chimerax/system_requirements.html

Thank you for your answer. I will give it a try.

I have also tried to install ChimeraX on a VirtualBox machine with Ubuntu 22 a first time, and Windows the second time. It did not work. I guess ChimeraX cannot be installed in virtualbox machines. Could you confirm it?

Thanks once again,

Miguel

ChimeraX 1.4 (and the 1.5 release candidate) needs Ubuntu 20 or newer. So the procedure for Ubuntu is to first update the operating system. Then install ChimeraX.

Unfortunately, we don't support openSUSE. But I was able to get the RHEL 8 rpm to appear to work on openSUSE 15.4. So, after downloading ucsf-chimerax-1.4-1.el8.x86_64.rpm:

sudo zypper install ~/Downloads/ucsf-chimerax-1.4-1.el8.x86_64.rpm

then skip the missing cario-gobject (since I installed Xfce instead of Gnome). Then it complains that the package header is not signed. Ignore that. Then, not all of the dependencies are there. Fix the missing libGLU.so with:

sudo zypper install libGLU1

then fix the fact that openSUSE has libffi.so.7 and ChimeraX is expecting libffi.so.6 with:

sudo ln -s /usr/lib64/libffi.so.7 /usr/libexec/UCSF-ChimeraX/lib/libffi.so.6

And after all that, I was able to run /usr/bin/chimerax. There were some warnings and errors in the terminal window, but I was able to open an mmCIF file from the PDB. So not a complete test, but a good start.

HTH,

Greg

Hello,

I am trying to install ChimeraX on Ubuntu 16.04 or openSUSE Leap 15.2 without success.

Is it possible? If so, what would be the procedure?

Thanks, Miguel

Elaine, Greg,

Thank you very much for the amazing support.

Best, Miguel

I have not had any luck with VirtualBox, but I haven't tried it in a long time.  VMware Workstation 16 Player works well enough for debugging.  But you will loose performance by not running ChimeraX natively.  And if you find a bug, we might not be able to fix it -- that is the bug fix will be to run ChimeraX natively. Your call.
