Same operating system as @mkrzewic. Slightly newer master version of ROOT @615eaf63.

When running cmake ../root -DCMAKE_CXX_STANDARD=17 -DCMAKE_BUILD_TYPE=RelWithDebInfo, the following error is reported:

[...]
-- Building Cling as part of ROOT
CMake Error at interpreter/cling/CMakeLists.txt:196 (message):
  NVPTX backend is not activated

  Please enable it via -DLLVM_TARGETS_TO_BUILD="host;NVPTX"

-- Configuring incomplete, errors occurred!

When running cmake ../root -DCMAKE_CXX_STANDARD=17 -DCMAKE_BUILD_TYPE=RelWithDebInfo -DLLVM_TARGETS_TO_BUILD="host;NVPTX", the following error is reported:

[...]
-- Building Cling as part of ROOT

CMake Error at interpreter/llvm-project/llvm/cmake/modules/LLVM-Config.cmake:138 (message):

Removing the "host" string from the list LLVM_TARGETS_TO_BUILD, seems to fix the issue, as running cmake ../root -DCMAKE_CXX_STANDARD=17 -DCMAKE_BUILD_TYPE=RelWithDebInfo -DLLVM_TARGETS_TO_BUILD="NVPTX" results in successful build configuration.

Following this, ROOT successfully compiles almost all the way up to 100%:

As for the original CMake configuration error, my guess is that the CMake target "host" used to be part of the CMake project, but is no longer part of the CMake project, and that the error message in interpreter/cling/CMakeLists.txt:196 was not updated to reflect this when the CMake target "host" was removed from the CMake project.

As for the error on the final generation of lib/modules.idx, the issue seems to be with root.exe which is invoked with the following build step command: 

cd /usr/home/erik/devel/resources/root/build/lib && LD_LIBRARY_PATH=/usr/home/erik/devel/resources/root/build/lib: ROOTIGNOREPREFIX=1 ROOT_HIST=0 /usr/home/erik/devel/resources/root/build/bin/root.exe -l -q -b

Running root.exe by itself generates an Abort trap (core dumped).

Have you stumbled upon this issue previously, @mkrzewic, and if so, have you managed to deal with it somehow?

mkrzewic commented 11 months ago

@eamjensen yes, the modules.idx thing was already solved in the first FreeBSD related patches but I don't remember what was the problem exactly, I'll see if I can dig it up...

mkrzewic commented 11 months ago

@eamjensen -DLLVM_TARGETS_TO_BUILD="NVPTX" helps, thanks. I'll close this for now. the modules.idx problem might need a separate ticket, feel free to open one for the record, when time allows I'll come back to this if it is not solved by then.
