[Plugin] Loading error

[Rémi Deletrain]

Hi everyone,

I have loading errors each time I use plugins that use OpenGL.

For exemple with Sampler plugin (webSite, github) or pixarUSD. (Unable to dynamically load : D:/bla/bla/bla/pxrUsd.mll)

I already compile the usd several times and I had no problem loading plugin. But now I can not do it anymore.

Here is the adaptation of the plugin Sampler for maya2018.

I can not understand why he does not want to load into my maya. If anyone has a solution...

[Rémi Deletrain]

it seems that the problem comes from glew.

the USD update the file glew.h. Hence the problem of loading in maya. And so it's the same problem for the Sampler project.

I found this page. So I try to build with version 1.10.0 but it's same problem...

Could it be that the dynamically linked library for GLEW isn't available on your PATH? On Windows, that would be `glew32.dll`, on Linux I expect it would be `glew32.so`. A project like USD probably has lots of dynamic libraries, so maybe there's a more overarching directory missing from your PATH somewhere.

It seems to me that windows takes as the first path the one where we load the plugin.

I also tried to add the path in environment variables but it does not change anything

That’s what I would expect as well, but it hasn’t been my experience.

Have a look at what dumpbin tells you about the dependencies of that plug-in, and make sure each of those are accessible on your PATH.

For example.

$ "c:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\bin\dumpbin.exe" /DEPENDENTS rawfootPrintNode.mll
Microsoft (R) COFF/PE Dumper Version 14.00.24215.1

Dump of file rawfootPrintNode.mll

Thank you for your reply Marcus,

I have all dependencies... It's possible glew is now incompatible with maya 2018.

A colleague try with glext and it's works for her plugin. I try with my plugin now.

[Marcus Ottosson]

Maya 2018 switched from VS2012 to VS2015, so if the GLEW binary was built for Maya 2017 and before, it's quite likely it will need to be recompiled with VS2015.

Hi Marcus,

Ok I try that.

[Rémi Deletrain]

Ho yeah it's works when I build glew with VS2015.

Thank you Marcus
