X11/Xcursor/Xcursor.h: No such file or directory

[informatter]

Hi everyone,

I have been trying too build with cmake --build build --config RelWithDebInfo -j 4 However I am always getting:

fatal error: X11/Xcursor/Xcursor.h: No such file or directory

I have all the system requirements and have done all the steps in the README.

I am trying to compile the project on on a AWS Deep Learning AMI Instance (Ubuntu 18.04) Version 50.0

The full output after running cmake --build build --config RelWithDebInfo -j 4 is the following:

I am stuck in this step and I am unsure of what might be causing the build issue. Any help would be much appreciated!

Thanks

Looks like certain GUI-related headers aren't installed on that machine. You could try compiling without GUI support -- then the compilation won't try to loop in GL and X11 stuff: delete your build folder and add -DNGP_BUILD_WITH_GUI=off to the CMake calls.

@Tom94 thanks for the pointer! Also, after running cmake --build build --config RelWithDebInfo -j 16 it builds successfully but I am getting a bunch of warnings which say:

warning: calling a host function from a host device function is not allowed

Is this just related to CUDA and the build process?

Its quite a long log, so I am just posting a truncated version:
