When I compiled 'libflattenconcat.so' on ubuntu, it reported an error I follow the process below： $ {tensorrt}/samples/python/uff_ssd $ mkdir build $ cd build $ cmake ../ $ make I also try sudo to build it ,it still report errors

(base) wyl@wyl-Inspiron-3670:~/software/pc/TensorRT-6.0.1.5/samples/python/uff_ssd/build$ sudo cmake ../ -- The CXX compiler identification is GNU 7.4.0 -- Check for working CXX compiler: /usr/bin/c++ -- Check for working CXX compiler: /usr/bin/c++ -- works -- Detecting CXX compiler ABI info -- Detecting CXX compiler ABI info - done -- Detecting CXX compile features -- Detecting CXX compile features - done -- Looking for C++ include pthread.h -- Looking for C++ include pthread.h - found -- Looking for pthread_create -- Looking for pthread_create - not found -- Looking for pthread_create in pthreads -- Looking for pthread_create in pthreads - not found -- Looking for pthread_create in pthread -- Looking for pthread_create in pthread - found -- Found Threads: TRUE

The following variables are derived from the values of the previous variables unless provided explicitly:

Please set them or make sure they are set and tested correctly in the CMake files: _NVINFER_LIB linked by target "flattenconcat" in directory /home/wyl/software/pc/TensorRT-6.0.1.5/samples/python/uff_ssd

I have fixed it firstly: mkdir build cd build sudo cmake .. -DNVINFER_LIB=/home/wyl/software/pc/TensorRT-6.0.1.5/lib/libnvinfer.so

note: it is DNVINFER_LIB not NVINFER_LIB

secondly: in /software/pc/TensorRT-6.0.1.5/samples/python/uff_ssd/plugin/FlattenConcat.cpp Modify the path of the import NvInferPlugin.h
