vaporgui seg fault
Hi All, I have been attempting to remedy a segmentation fault when invoking vaporgui. I am attempting to run vapor by using vglrun through the TurboVNC client. Everytime I attempt to run it by using vglrun vaporgui it instantly says segmentation fault and refuses to run. I am using vapor 2.5.0 on the Linux Mint 18.1 platform on both server and client side. Server side I am running with 256gb of ram and 2 - Nvidia GTX 1080 TI Duke video cards. When I plug a monitor into the server directly vapor runs perfectly without issue. Any ideas as to how I might be able to get this working? Thank you, Marshall Stageberg Michigan State University

Hi Marshall,

 

The problem is a little bizarre since we use vapor with turbovnc all the time. Before we dig into any particular problems, could you give the vapor 2.6.0 release a try? That's our latest. You want to grab the RHEL7 installer.

 

Let us know how it goes.

Hi Samuel, I have downloaded and installed the vapor 2.6.0 release using the RHEL7 installer and ran into another error trying to use that release beyond the segmentation fault. I get the error "Cannot load library icui18n". I have the library it is looking for in my: /usr/lib/x86_64-linux-gnu folder. I set the LD_LIBRARY_PATH to point to that directory and that removed that error however it still produced the segmentation fault. I ran ldd ./vaporgui and all the paths were pointing to valid directories so I am not really sure what is going on. Thank you, Marshall

Hi Marshall,

A few comments here.

First, the "Cannot load library icui18n" error doesn't seem to affect anything based on user feedbacks...

Second, if you installed VAPOR using the installation script, and also "sourced" the setup file, you shouldn't need to manipulate LD_LIBRARY_PATH by yourself. I'd encourage you follow the installation steps and give it one more try.

Third, I still have no clue about the seg fault. Worse, we don't have a Ubuntu/Mint machine to test. At this point what I could suggest is to also try the RHEL6 installer... It uses old 3rd party libraries, but might have better compatability...

Sorry for not being more helpful... We're definitely keeping this error in mind, and connect once we discover something new.

 

Best,

Samuel

Hi, was there any progress with this issue? I'm trying to run Vapor 2.6.0 in a VirtualGL + TurboVNC setting (Fedora Core 26), but I also have a segmentation fault. I can give further info on versions of all relevant apps/libraries if this might help to find a solution for it. Cheers, AdV

What version of VirtualGL are you using, and are you running vapor from a binary installer, or a source build?
