nftSimple and NFT detection crash on Linux

[martial]

Hi all,

I'm trying to port ofxArtool5 with NFT tracking with openFrameworks.
Everything works very well under Mac OS but I'm having several issues with NFT tracking under linux systems.

I've been trying various ArToolKit versions ( 5.2, 5.3, 5.4 and artoolkitx fork ), with various OS ( Ubuntu 18 and Fedora ), and on different machines.
I tried official releases binaries and also the ones I compiled.
I've been trying with multiples webcams and configurations.

Everytime nftSimple is crashing randomly, usually before 1 sec of execution.

Anyone has been having this issue ?

Thanks for your support

Hi @martial what app are you testing? from the Artoolkit5 examples? or do you have yet developed your addon for OpenFrameworks? It could be also a problem with the type of compiler you used (clang or gcc)... Just an idea!

@martial: are you using v4l2?

Maybe this is related to this issue #173 ?
