Debian Sid fatal error unexpected signal during runtime execution

[omac777]

For Debian Sid, I installed the following: apt-get install libglfw3-dev apt-get install libvpx-dev apt-get install libogg-dev apt-get install libvorbis-dev apt-get install libopus-dev apt-get install portaudio19-dev

Otherwise you will get the following error output: go get github.com/xlab/libvpx-go/cmd/webm-player

[xlab]

@omac777 Much thanks for the report and installation instruction. I'll add those into README.

As for crash, I think this is highly related to this bug: https://github.com/golang-ui/nuklear/issues/1 I haven't yet tested GLFW+Nuklear with Linux distros, seems that GLFW fails to initialise the context properly. I'll try to play around this and fix on this weekend. Stay tuned.

[xlab]

@omac777 Could you try this again please? I've updated the GUI library https://github.com/golang-ui/nuklear/issues/1#issuecomment-257089763

Works even for windows.

[xlab]

I guess it's resolved.
