Error compiling Renderlib in VisualStudio Community 2015

[philboltt]

Hi,

I'm trying to compile this for Maya 2016 on Windows 10/Visual Studio 2015. CoreLib compiles successfully, but when I try to compile RenderLib I get the following error:

This appears to point to an issue in the CoreLib library (corelib\include\containers/list/list.h) but I'm at a loss as to how to solve this. Any pointers?

Thanks!

Hi Phil,

I assume you're using the latest version of the Core/Render libs? just wondering if the submodules could be pointing to an outdated version which has been patched later on. Last time I compiled this code was for maya 2015, but the error is not related to maya so I wonder if this is a version problem. Please try pulling the latest version from those projects https://github.com/joesfer/CoreLib https://github.com/joesfer/RenderLib

Failing that, the error seems related to a templated version of CoreLib::List being instantiated more than once on two different parts of the code. This could be because the list is instantiated on a header file or an inlined method included in more than one cpp, which would re-declare the methods on the list. The error doesn't give a lot of information, but without actually compiling the code on my current machine, I suspect the specific issue with the bracket operator is just whatever happens to be compiled first. The code could be stale, but again, I don't expect this to be a maya-related issue.

Hi Jose,

Many thanks for having a look at this. I tried building from the versions you linked to in your reply, but got the same result. I agree that the error is completely unrelated to Maya - just mentioned that for completeness. I'll have a dig around to see if I can trace where CoreLib::List is getting double-instantiated, but I'll admit I'm a bit rusty with my C++. Do you think this could have anything to do with the version of Visual Studio that I'm using?

Hi Phil,
I've only been able to recently test this on Linux using GCC 5.4, but I've just cloned the sources on a clean folder, followed the instructions (using CMake) and built CoreLib, then RenderLib, and then the Grower all by virtue of cmake + make. It all seems to be compiling just fine as far as I can tell. I also noticed that the last set of commits to the CoreLib repo are to do with fixing compilation issues with GCC, so you may want to make sure those are pulled in your repo. FWIW, they were on mine when I did 'git submodule init' and 'git submodule update'.
