Yes,
after more reading and thinking, I think it might need some adaptation
of the tools. CMake targets NVCC, I was kinda hoping that it would spew
out the nvcc options that could then be fed to the tools I want to yo use.
But those specific tools are all clang based, so they probably don't
know about nvcc commands. I don't know how genric that compilation
database is. (although for what I want, the tools probably only need gcc
compatible flags, like -D and -I to recognise defines and include paths.
If you tell them to work in C++ mode, you can actually get them to run
on *.cu files as clang knows about CUDA, so they just need to know about
include paths.)
Maybe it would work if I made a CMake file without using NVCC to target
clang directly as a specific compiler for *.cu file.
So from what I currently understand, what you suggest might be the
simplest. Parse the verbose output and make my own compilation database.
Thanks,
Urs

Presuming makefile target, would it help if after CMake you do "make
VERBOSE=1" ? Verbose mode should show all compilation commands, maybe
you could further parse them into the format you want.
Kind regards,

Hi,
I'm trying to get CMake to output a compilation database for my
project
using gcc and CUDA (nvcc). I'd use the compile_commands.json file for
rtags navigation in emacs and clang-tidy inspection.
To do that, I just added
set(CMAKE_EXPORT_COMPILE_COMMANDS 1)
to my CMakeLists.txt
But it looks like the output I get is only having the information for
the *.cpp files. It looks like the *.cu files are all compiled as
external objects taht have their own cmake code in subroutines and
are
not built by the Makefile generator.
I'm not a cmake expert, is what I'm trying to do possible? Am I doing
something wrong somewhere?
Thanks,
Urs
