Build error when using make in official nvidia docker

[TomEelbode]

I'm trying to build this project from source in a docker container (I'm using a clean nvcr.io/nvidia/l4t-tensorflow:r32.4.2-tf1.15-py3 image).

However, the make command gives the following error:

I believe nvcaffe_parser functionality is now in nvparser library, so you should be able to remove it from CMakeLists.txt

@dusty-nv Thanks for your quick reply! I have tried this, but a new error arises later on (see below).

Just to make sure that I did exactly what you meant: I replaced this line in jetson-inference/CMakeLists.txt
target_link_libraries(jetson-inference jetson-utils nvinfer nvinfer_plugin nvcaffe_parser)
by
target_link_libraries(jetson-inference jetson-utils nvinfer nvinfer_plugin)

The new error on executing make is

[ 53%] Linking CXX executable ../../aarch64/bin/imagenet-console
../../aarch64/lib/libjetson-inference.so: undefined reference to nvcaffeparser1::createCaffeParser()' ../../aarch64/lib/libjetson-inference.so: undefined reference to nvuffparser::createUffParser()'

UPDATE: it works now :)

I stupidly forgot to link the mentioned nvparser libary instead.

The line in CMakeLists.txt should be (mind that it's nvparsers and not nvparser):
target_link_libraries(jetson-inference jetson-utils nvinfer nvinfer_plugin nvparsers)

This line should be changed in the following files:

jetson-inference/CMakeLists.txt
jetson-inference/tools/trt-bench/CMakeLists.txt
jetson-inference/tools/trt-console/CMakeLists.txt

Using nvparsers instead of nvcaffe_parser works with nvcr.io/nvidia/l4t-ml:r32.4.3-py3
