V-Ray slave: what should LD_LIBRARY_PATH be set to?

[Fredrik Averpil]

Hi,

I was wondering exactly what I need in my LD_LIBRARY_PATH on Linux in order for vray slave to function properly. I'm on V-Ray 3 stable build 25208.

Inheriting an old setup from V-Ray 2.x and early 3.x beta, I've been using the following, which I noticed now results in an error:

[vray_installation]/maya_root/lib
[vray_installation]/vray/lib/linux_x64/gcc-4.4
[maya_installation]/plug-ins/xgen/lib

The error, when launching [vray_installation]/maya_vray/bin/vray.bin -server -portNumber=20210:

/192.168.0.225/Pipeline/bin/vray/builds/141107_stable_v25208_maya2015_linux/maya_vray/bin/vray.bin: symbol lookup error: /192.168.0.225/Pipeline/bin/vray/builds/141107_stable_v25208_maya2015_linux/maya_root/lib/libvray.so: undefined symbol: _ZNK9QCheckBox15minimumSizeHintEv

If I remove the first path (listed above) which points to a lib folder in the Maya installation, it seems that the slave starts up without errors.

There are two versions of libvray.so - one is linked against Qt for the VFB and is used inside Maya, the other one is linked against the X libraries directly and is used by V-Ray Standalone. You need the second one. So the first entry is indeed superfluous.

Best regards,
Vlado

Allright, thanks!
