I removed the out-of-date flag. If the CUDA parts dont compile with GCC 8, that's an upstream bug. You should take it up with PCL directly.

Since this package builds the master from github, it can't really be out of date.

The build directory is already separate. Also, the build directory is only removed in the prepare() function, which isn't run with makepkg -e. So I don't really see a problem with the current PKGBUILD.

Suggestion to change PKGBUILD: https://github.com/majorx234/pcl-git-PKGBUILD

reasons: cmake part in build() function: so you can use makepkg -e to build with already downloaded sources. seperate build directory, to keep source code and cmake generated files apart.

Cuda wants GCC6

/opt/cuda/include/crt/host_config.h:121:2: error: #error -- unsupported GNU version! gcc versions later than 6 are not supported!
 #error -- unsupported GNU version! gcc versions later than 6 are not supported!
  ^~~~~

To fix:

Install gcc6 and add the following lines before the cmake command:

export CC=/usr/sbin/gcc-6
export CXX=/usr/sbin/g++-6

OpenNI prohibits to build on Linux

/usr/include/ni/XnPlatform.h:73:3: error: #error OpenNI Platform Abstraction Layer - Unsupported Platform!
  #error OpenNI Platform Abstraction Layer - Unsupported Platform!
   ^~~~~

Fix: I just uninstalled openni.

Kernel build issues with Cuda 9.1.85

2 errors detected in the compilation of "/tmp/tmpxft_00006c3e_00000000-13_normal_3d.compute_70.cpp1.ii".
CMake Error at pcl_cuda_features_generated_normal_3d.cu.o.Release.cmake:279 (message):

I did not bother to fix the following one, so I disabled cuda all together for now. Proper patches are welcome.

        -DBUILD_CUDA=OFF \
        -WITH_CUDA=OFF

It still builds some cuda stuff with that, so you need the first fix anyway.
