Problem when build appleseed on linux

[Yuheng Zou]

I tried the instructions in wiki page. Download the prebuilt-deps and then install qt on linux by apt-get. Then I get the following error:

Does anyone have some solutions?

Hi,

Are you using a recent gcc version?

I think that the issue is related to this:

https://gcc.gnu.org/onlinedocs/libstdc++/manual/using_dual_abi.html

The prebuilt dependencies are built using gcc 4.8,using the old ABI and are not compatible 

with the new C++11 ABI using in recent gcc versions.

The solution is to define _GLIBCXX_USE_CXX11_ABI=0. You can modify the cmake files to add it 

or use cmake-gui or cmake command line to add the definitions to cmake's CXXFLAGS.

Est.

Hi,

Thank you very much! This solves my problem completely.

May I join you as a contributor? I am now a sophomore from China. I love computer graphics and want to practice my skills. I find appleseed is a good place to start and I want to meet people who are experienced on CG.

I am a gold medal winner in CNOI (China National Olympiad in Informatics), so I know the basic algorithm. I took the computer graphics class in Peking University last year, and wrote a simple path tracer. The code is here: https://github.com/KuribohG/z-renderer. I accomplished a fluid simulator as a final project in group at: https://github.com/KuribohG/Waterflow. However, I don't know much in software engineering so these code is hard to read and maintain.

I want to know how is the renderer like in product, and how to build large size software. This is why I want to join appleseed.

Thanks,

Yuheng

Hey Yuheng,

Welcome, it'll be a pleasure to have you!

The best is to join us on Slack, this is where most of the discussions take place nowadays.

Could you request an invite here please? https://slackin-hjzwcqzcjp.now.sh/ This auto-invite thing is a bit experimental so let us know here if it doesn't work properly.

Franz

Hello Franz,

This link works fine for me. I can receive the email from it.

Thanks,
