terminate called after throwing an instance of 'cl::sycl::compile_program_error'
  what():  Failed to load libsycl-fallback-cassert.spv -30 (CL_INVALID_VALUE)

i can't find the libsycl-fallback-cassert.spv in build/lib

i tried adding libdevice to DLLVM_EXTERNAL_PROJECTS and set DLLVM_EXTERNAL_LIBDEVICE_SOURCE_DIR as in #1276 but still can't find anything. what else do i need to build these files? it worked a few weeks back but now following the path in getting started doesn't work for me.

You need to add libdevice to LLVM_ENABLE_PROJECTS variable.
The easiest way to configure CMake is to use https://github.com/intel/llvm/blob/sycl/buildbot/configure.py script.

thanks for the quick answer! i used that script but only updated external_projects.

i will compile, verify and close the issue.
and probably send a PR for gettingstarted
