Is any one had similar problem? where i tryed to create my own CGF example the compiled lib is not recognized by nodedescriptor tool,
I am able to run hello world cgf example compiled so, but not the my own example.
this is the error i get “Failed to dlopen ‘libcgf_custom_nodes_test.so’: libcgf_custom_nodes_test.so: cannot open shared object file: No such file or directory”
src.zip (9.4 KB)
Any suggestions? thank you.
Dear @sushant.bahadure,
Could you share the followed steps?
steps I followed were as follows
- created .json files using dw cgf ui tool
- modified impl.cpp and impl.hpp for adding logic similar to helloworld cgf example
- copiled using cmake -B /mydir/build -DCMAKE_TOOLCHAIN_FILE=/usr/local/driveworks/s
amples/cmake/Toolchain-V5L.cmake /mydir1/mydir2/samples/
- after .so is generated i tried to use nodedescriptor tool ./nodedescriptor /path_till_libfile/libcgf_custom_nodes_test.so or /usr…/tools/nodedescriptor/nodedescriptor ibcgf_custom_nodes_test.so
error states nodedescriptor is not able to find .so
Hi @SivaRamaKrishnaNV an gentle reminder, If you need anything more please let me know. Thank you.
Dear @sushant.bahadure ,
Could you remove the -DCMAKE_TOOLCHAIN_FILE from the compile command. it generates shared object for aarch64 and you are trying to load it on x86.

Thank you, i didn’t realize this could be the problem.
