Problems with installing jetson inference

hi,
i’m a complete beginner in this Topic… sorry if i’m asking a stupid question.
i have a Jetson TX2 flashed with Jetpack 4.2. i wanted to test a project with the ZED-camera, but therefore i need several programs to run.
i followed the guide on this page https://github.com/yankailab/jetson-inference-batch. the cmake worked without a mistake, but when i wanted to start the make there is the following error Message:

Does someone have any idea how to fix the C++11 warning? And more important the other mistake which stopped the make process. i was searching the whole day in the forums, but didn’t find something to fix it. thank you very much in advance :)

Hi Alexe, you were using a fork of the repo that was outdated and hadn’t been updated for JetPack 4.x.

Please try to see if you can build the repo from master: [b][url]https://github.com/dusty-nv/jetson-inference[/url][/b]

Hi Dusty,

thank you very much for your really fast answer. i tried the things you told me, but there is still a mistake somewhere.
There is still the warning about the C++11 thing and also this:

[ 43%] Building CXX object utils/CMakeFiles/jetson-utils.dir/threads/Thread.cpp.o
[ 44%] Linking CXX shared library …/aarch64/lib/libjetson-utils.so

make[1]: *** [utils/CMakeFiles/jetson-utils.dir/all] Error 2

do you have any suggestions what to do?

I was googeling the Problem i had and found some answer on this webpage make build error · Issue #309 · dusty-nv/jetson-inference · GitHub
My Output looks like this: lrwxrwxrwx 1 root root 41 may 10 09:27 /usr/lib/aarch64-linux-gnu/libGL.so → /usr/lib/aarch64-linux-gnu/tegra/libGL.so

-rw-r–r-- 1 root root 972968 ago 15 2018 /usr/lib/aarch64-linux-gnu/libGL.so.1.0.0

but i’m not sure if this is a problem or not(if it’s one, then do you have any hint what to do?), could you please help me?
