TensorRT Build Failing on Jetson Nano

[gatordevin]

Hello, I am trying to follow the guide to install the r2inference library on a jetson nano. For my backend, I am using TensorRT which your documentation said is already included on the Jetson Nano with Jetpack 4.3 which I currently have installed. When I run the ninja build command I get the following error.

ninja: Entering directory build' [57/95] Compiling C++ object tests/unit/r2i/tensorrt/engine.p/engine.cc.o FAILED: tests/unit/r2i/tensorrt/engine.p/engine.cc.o c++ -Itests/unit/r2i/tensorrt/engine.p -Itests/unit/r2i/tensorrt -I../tests/unit/r2i/tensorrt -I. -I.. -I/usr/local/cuda-10.2/targets/aarch64-linux/include -I/usr/include/glib-2.0 -I/usr/lib/aarch64-linux-gnu/glib-2.0/include -fdiagnostics-color=always -D_FILE_OFFSET_BITS=64 -Wall -Winvalid-pch -Wnon-virtual-dtor -std=c++11 -g -pthread -MD -MQ tests/unit/r2i/tensorrt/engine.p/engine.cc.o -MF tests/unit/r2i/tensorrt/engine.p/engine.cc.o.d -o tests/unit/r2i/tensorrt/engine.p/engine.cc.o -c ../tests/unit/r2i/tensorrt/engine.cc In file included from ../tests/unit/r2i/tensorrt/engine.cc:26:0: ../tests/unit/r2i/tensorrt/mockcudaengine.cc:97:18: error: cannot declare field ‘nvinfer1::{anonymous}::MockExecutionContext::cuda_engine’ to be of abstract type ‘nvinfer1::{anonymous}::MockCudaEngine’ MockCudaEngine cuda_engine; ^~~~~~~~~~~ ../tests/unit/r2i/tensorrt/mockcudaengine.cc:22:7: note: because the following virtual functions are pure within ‘nvinfer1::{anonymous}::MockCudaEngine’: class MockCudaEngine : public ICudaEngine { ^~~~~~~~~~~~~~ In file included from /usr/include/aarch64-linux-gnu/NvInfer.h:53:0, from ../r2i/tensorrt/model.h:17, from ../r2i/tensorrt/engine.h:18, from ../tests/unit/r2i/tensorrt/engine.cc:13: /usr/include/aarch64-linux-gnu/NvInferRuntime.h:1539:18: note: virtual bool nvinfer1::ICudaEngine::hasImplicitBatchDimension() const virtual bool hasImplicitBatchDimension() const TRTNOEXCEPT = 0; ^~~~~~~~~~~~~~~~~~~~~~~~~ ../tests/unit/r2i/tensorrt/engine.cc: In member function ‘virtual void TEST_GROUP_CppUTestGroupTensorRTEngine::setup()’: ../tests/unit/r2i/tensorrt/engine.cc:91:29: error: invalid new-expression of abstract class type ‘nvinfer1::{anonymous}::MockCudaEngine’ nvinfer1::MockCudaEngine, ^~~~~~~~~~~~~~ [59/95] Compiling C++ object tests/unit/r2i/tensorrt/frameworkfactory.p/frameworkfactory.cc.o ninja: build stopped: subcommand failed.`

Any ideas on how to fix this issue. If i understood the error I could attempt to troubleshoot but not exactly sure what's wrong.
