cant compile with cmake3 on centos 7

[willDTF]

the compile process won't go to the end and return this : `-- The CXX compiler identification is unknown CMake Error at cycles/CMakeLists.txt:42 (project): The CMAKE_CXX_COMPILER:

g++-6

is not a full path and was not found in the PATH.

Tell CMake where to find the compiler by setting either the environment variable "CXX" or the CMake cache entry CMAKE_CXX_COMPILER to the full path to the compiler, or to the compiler name if it is in the PATH.

Hey!

You will need to install GCC 6 on CentOS to make it compliant with VFX Platform 2018. If you take a peek at Gaffer's official docker builder it should give some hints to how your environment should look like here: https://github.com/GafferHQ/build/blob/master/Dockerfile

At home I use Kubuntu 18.04 which has named it gcc-6/g++-6 (the distro comes with v7 as default but that is too new) but it might be different on CentOS. Cheers!

Hi @Kaiz3rTool

https://github.com/boberfly/GafferCycles/releases/download/gafferCycles-0.1.0-gaffer-0.53.0.0/gafferCycles-0.1.0-gaffer-0.53.0.0-linux.tar.gz I have a test build here which you can path to GAFFER_EXTENSION_PATHS before launching Gaffer. This should work on 0.53.1.1 which is the latest released one right now.

Cheers

hi, thank you for your answer, I will take a look ASAP and thanks for invest your time on Gaffer-Cycles bridge, great idea !

@Kaiz3rTool you're in luck, I was just battling out this very issue as I was compiling on Ubuntu with GCC 6.5 but VFX Platform/CentOS 7 has GCC 6.3. If you try this build:

https://github.com/boberfly/GafferCycles/releases/tag/0.4.1

Can you verify that this gets around the above issue? It is my first build using CentOS 7 in a docker container which mirrors how Gaffer usually gets built from GafferHQ.

Cheers

I have tried it fastly, so far so good no errors on loading, shader assignment works, both interactiverender and render works as espected thanks a lot for your help

I have created a post on gaffer-dev group about your work

maybe someone from there can help you

Best
