I’m using deepstream_infer_tensor_meta_test.cpp and I’d like to use a custom gst-nvinfer instead of gst-nvinfer, how to compile it and use it in my code?
I compiled the sources as it explained in README in gst-infer folder and I generated the libnvdsgst_infer.so and I added it to gst-plugins in the lib folder. When I include the gstnvinfer.h in the deepstream_infer_tensor_meta_test.cpp it shows me this error
/usr/bin/ld: deepstream_infer_tensor_meta_test.o: undefined reference to symbol 'dlclose@@GLIBC_2.2.5'
/usr/bin/ld: /lib/x86_64-linux-gnu/libdl.so.2: error adding symbols: DSO missing from command line
collect2: error: ld returned 1 exit status
This is the makefile

In the makefile I specified the -L$(GST_INSTALL_DIR) -lnvdsgst_infer \ which is libnvdsgst_infer.so…
What is the issue is it a linker problem or symbolic link ?
