Environment

Ubuntu 20.04 vtk-7.1.1 pcl-1.8.0

Issue 1

Resolution: Modify vtkAtomic.h as follows:

// typedef detail::AtomicOps<sizeof(T*)> Impl;
typedef ::detail::AtomicOps<sizeof(T*)> Impl;

Issue 2

Resolution:

Check for the presence of libvtkFiltersParallelDIY2 in /usr/local/lib. If only libvtkFiltersParallelDIY2-7.1.so exists, create a symbolic link:

sudo ln -sv libvtkFiltersParallelDIY2-7.1.so libvtkFiltersParallelDIY2.so

Repeat for other missing VTK libraries.

Issue 3

Download ncnn:

git clone https://github.com/Tencent/ncnn.git

Navigate to the ncnn directory and compile:

mkdir build
cd build
cmake ..
make -j12

After compilation, copy the library files:

cd ncnn/build/src
sudo cp -n libncnn.a /usr/include
sudo cp -n libncnn.a /usr/lib

Issue 4

Resolution: Obtain camport3:

git clone https://github.com/percipioxyz/camport3.git

Copy shared library files:

cd camport3/lib/linux/lib_x64
sudo cp -n libtycam.so /usr/include
sudo cp -n libtycam.so /usr/lib
sudo cp -n libtycam.so.3.6.12 /usr/include
sudo cp -n libtycam.so.3.6.12 /usr/lib

Issue 5

Resolution: Update CMakeLists.txt in the perfect folder:

add_executable(rgbd_ty
  Examples/RGB-D/my_rgbd.cc)
target_link_libraries(rgbd_ty 
  ${PROJECT_NAME} 
  ${TY_TARGET_LIB})

//======= Change to ========
add_executable(rgbd_tum
  Examples/RGB-D/rgbd_tum.cc)
target_link_libraries(rgbd_tum
  ${PROJECT_NAME} 
  ${TY_TARGET_LIB})

Additional ncnn Setup

Run make install after building ncnn. Then, locate the install directory under build and update the header file path in perfect/src/Detector.h to point to the installed ncnn headers.

Compilation should now succeed.
