cmake_do_configure error with clang
Hi, I'm trying to compile AMD ROCm with meta-clang as it is llvm required for the project to compile.
I first started with this: https://github.com/RadeonOpenCompute/ROCm-Device-Libs but when I add meta-clang layer and TOOLCHAIN = "clang" to the recipe it fails with a lot of these:
| CMake Error at cmake/OCL.cmake:119 (add_custom_command):
| Error evaluating generator expression:
|
| $<TARGET_FILE:llvm-link>
| CMake Error at cmake/OCL.cmake:119 (add_custom_command):
| Error evaluating generator expression:
|
| $<TARGET_FILE:opt>
|
| No target "opt"
| Call Stack (most recent call first):
| hc/CMakeLists.txt:21 (opencl_bc_lib)
|
|
| CMake Error at cmake/OCL.cmake:89 (add_custom_command):
| Error evaluating generator expression:
|
| $<TARGET_FILE:clang>
|
| No target "clang"
For reference, recipe now does not do anything special:

PV = "rocm-4.0.0"
S = "${WORKDIR}/git"
TOOLCHAIN = "clang"
Right now, I'm using yocto lts 3.1.4 and dunfell branch in meta-clang. I've also tried to add export YOCTO_ALTERNATE_EXE_PATH = "${STAGING_LIBDIR}/llvm-config" but it didn't help.
Any clue what I'm doing wrong?
Thanks!
BTW, I had to cherry-pick https://github.com/kraj/meta-clang/commit/3427029851cd2654b1359ccbe7f111ff76655a81 because the expansion for gallium drivers in mesa was failing.
I've now realized the llvm-config is installed here: ./rocm-4.0.0-r0/recipe-sysroot-native/usr/bin/llvm-config so I've updated YOCTO_ALTERNATE_EXE_PATH to export YOCTO_ALTERNATE_EXE_PATH = "${STAGING_LIBDIR_NATIVE}/llvm-config" but the result is the same.
Here the full log file: log.do_configure.982348.log
@dagmcr can this issue be closed for master ? or is there anything more needed
Hi @kraj, I've tried with poky & meta-clang master branches but the result is the same:

Also, I've added DEPENDS += "clang" as I could see you are doing it for castxml_git.bb + TOOLCHAIN = "clang" but it didn't work.
Looking at what others are doing (e.g. https://aur.archlinux.org/cgit/aur.git/tree/PKGBUILD?h=rocm-device-libs) they are only specifying the LLVM_DIR and the install prefix.
The rocm-device-libs project specifies that it depends on amd-llvm but I initially considered that shouldn't be the problem.
Another thing I've tried was to point CMAKE_PREFIX_PATH to the recipe-sysroot/usr/lib/cmake/llvm but somehow the recipe cannot find the targets.
hmmm does setting export YOCTO_ALTERNATE_EXE_PATH = "${STAGING_LIBDIR}/llvm-config" help with master or no ?
I wonder if it needs llvm sources to be available and not just installed artifacts.
I see that it might need some more work to make this cross compile friendly, maybe use a prebuilt llvm-native tree and see if it can build using that build tree via -DLLVM_DIR

Maybe that's what I'm missing as the documentation always points to the llvm build directory (and here).

I was looking to use llvm-project-source.bb and maybe compile it as llvm external project but I think it wont be the best approach.
I'll give it a shot to the llvm-native.
Thank you for the help @kraj.
