detection of out-of-tree build at

opencl-clang/CMakeLists.txt

Line 43 in a7c9499

if(CMAKE_SOURCE_DIR STREQUAL CMAKE_CURRENT_SOURCE_DIR)

seems not working for the above build

[kloczek]

llvm/clang projects are really big.
Preparing build procedure with assumption that it will be done with without prebuild binaries IMO does not make to much sense.

So what kind of cmake options should I use? 🤔

[wenju-he]

I assume you're running cmake command in opencl-clang root source folder, right?

1. I noticed that your system installed llvm 16.0.5 but opencl-clang is looking for llvm 16.0.0. Could you please try to add -DPREFERRED_LLVM_VERSION="16.0.5" to cmake command?
2. There is error in find_package(LLVM...) as shown at the bottom of the error log. It seems LLVM isn't correctly configured.

Is "terminfo database" library installed on your system? If not, could you please try to install it?

Result is the same if I'm not passing -D PREFERRED_LLVM_VERSION=<llvm.version>

[ht990332]

I have clang 16.0.6 and the includes are in /usr/lib/clang/16/include

[ht990332]

[wenju-he]

@ht990332 I met similar issue and it was fixed by #442

Does you system have /usr/lib/clang/16.0.6/include folder? If yes, cl_headers/CMakeLists.txt uses this folder instead of /usr/lib/clang/16/include.

What's your operating system?

BTW, could you please also check if file /usr/lib/clang/16/include/opencl-c-base.h exists on your system?

thank you. I got that to build already. the header exists.
the next issue is intel-graphics-compiler. it appears to not build with llvm/clang 16.

np. For intel-graphics-compiler issue, please ask on its github

[kloczek]

Just FTR. Here is set of cmake options which I'm using (quote from clang.spec file)

Sorry I've been looking on wrong spec (clang.spec instead intel-opencl-clang.spec) file.
Here is what I have in intel-opencl-clang.spec:

%cmake \
        %{nil}
%cmake_build

and no patches.

I've tested with USE_PREBUILT_LLVM=ON and result is still negative:

@kloczek could you please check if USE_PREBUILT_LLVM is true at

opencl-clang/cl_headers/CMakeLists.txt

Line 2 in 6d22310

if(USE_PREBUILT_LLVM)

Since you're using prebuilt llvm, USE_PREBUILT_LLVM should be true, however,

opencl-clang/cl_headers/CMakeLists.txt

Line 5 in 6d22310

set(CLANG_COMMAND $<TARGET_FILE:clang>)

is executed, meaning USE_PREBUILT_LLVM is not true.

copy_file(${CMAKE_CURRENT_SOURCE_DIR}/module.modulemap module.modulemap)

Are you using the head of ocl-open-160 branch of opencl-clang?

[kloczek]

is executed, meaning USE_PREBUILT_LLVM is not true.

On first look it looks like all what is related to USE_PREBUILT_LLVM should be removed because used llvm should always prebuild 😋
