problem linking libjetson-inference.so #136

Closed phojjat closed 1 year ago

phojjat commented 6 years ago

Hello,

I have built your examples on my jetson tx2 and everything works correctly. Now I am trying to build a standalone inference code based on the provided jet-inference code in Code blocks IDE. Receiving images from camera works okay, however when I extend it to include inference using libjetson-inference.so I cannot run the executable due to the following error "cannot open shared object file: No such file or directory". I have ran an ldd on the library and linked all the dependencies that show up, but that has not solved the issue. I am wondering what other steps I need to take to fix this. Any help is appreciated.

Thank you!

Hmm...are you using cmake to build your custom application, or else any differences in the link line?

You could try running make install or sudo make install after you run make on jetson-inference. It will install the libs to the standard locations.

I am using code blocks IDE which compiles and runs from within the application. I have linked libjetson-inference. http://libjetson-inference.io/so along with the dependencies I found through ldd but the issue persists.

As per CMakeLists.txt:6, jetson-inference compiles with -std=c++11 flag. This is because TensorRT also uses c++11. Are you building with that flag too from Code Blocks?

phojjat commented 6 years ago

Yes. I solved the issue by adding the path of the library to the config file as per: https://lonesysadmin.net/2013/02/22/error-while-loading-shared-libraries-cannot-open-shared-object-file/ https://lonesysadmin.net/2013/02/22/error-while-loading-shared-libraries-cannot-open-shared-object-file/
