Vscode-cpptools: Loading shared library to debug with executable

[rytisss]

What i am doing basically is building shared library and linking it to my executable. Project build and runs just fine. But when it come to debugging i can't do it (---If i debugging executable alone, there not problems, i can debug and everything works). Problem appears when i am launching debbuger. This is output with logging:

Should i include my library (*.so) file to 'launch.json'? or am i doing something not correctly?

Your program, TestYolo4Video is existing with 0x000000b1. Can you tell me what that error code is? Is it relying on some environment variables that are missing when being run under the debugger?

[iFuSiiOnzZ]

Hi, I have the same problem, exiting with error 0177 as some DLL are missing. I would like to know how do I specify in the launch configuration where the additionals DLL can be found?

Never mind, I found solution, don't know if is the best but work:

replace
"text": "set solib-search-path /media/ajianu/SSD/linux/carla/Build/llvm-5.0-install/lib"
with:
"text": "set env LD_LIBRARY_PATH=${workspaceFolder}/Build/llvm-5.0-install/lib"

[ishangupta0007]

@iFuSiiOnzZ I have tried the way you suggested above but I still have te same error. I also tried ""text": "set set solib-search-path /usr/lib/x86_64-linux-gnu/" using this. I have attached my launch.json file. Could somebody help me here?
