cranvas on Redhat

[chxy]

Hi everyone,

I got cranvas installed on RHEL5 with R-3.0.1 and Qt-4.8.4, but none of the examples could run successfully (R crashed every time). Does anybody have any clue on the error below?

Thanks,
Xiaoyue

Possible actions:
1: abort (with core dump, if enabled)
2: normal R exit
3: exit R without saving workspace
4: exit R saving workspace
Selection: 3

Warning messages:
1: Vertex shader for simpleShaderProg (MainVertexShader & PositionOnlyVertexShader) failed to compile
2: Fragment shader for simpleShaderProg (MainFragmentShader & ShockingPinkSrcFragmentShader) failed to compile
3: QGLShaderProgram: shader programs are not supported

Xiaoyue,

Did you work this out? I've got cranvas installed with the latest version of R and RStudio, on the Mac now.

cheers,
Di

Di,

No, I still have no idea. RHEL5 is the operating system of everyone's virtual machine here, so John wants me to get cranvas installed. However, many packages and software under RHEL5 are out of maintainance for quite a while so I have to install them from source (including Qt, cmake, R). I don't know if this is part of the reason.

Best,
Xiaoyue

I think that this is the usual complaint with redhat, that it is just not kept up to date. I think it is not a developers choice of linux. I'm not going to be much help - but good luck.
