Cannot build Intel Implicit SPMD Program Compiler: CMake Error at cmake/LLVMConfig.cmake: Failed running

[kevinsmia1939]

Hello,

I tried to build Intel® Implicit SPMD Program Compiler (ISPC) but failed.
https://github.com/ispc/ispc

Not really sure what happen, maybe something not compatible with LLVM bundled in the Sdk?

flatpak-builder 1.0.12

-- Detected LLVM version: 11.1.0
CMake Warning at cmake/LLVMConfig.cmake:134 (message):
  LLVM was built without assertions enabled (-DLLVM_ENABLE_ASSERTIONS=OFF).

arm architcture isn't supported in freedesktop-sdk runtime anymore. The same thing happens with LLVM form runtime. I think you have to set:
-DARM_ENABLED:BOOL=OFF

[kevinsmia1939]

-DARM_ENABLED:BOOL=OFF

Thanks, this work.

But now ISPC need glibc-32bit, which need libc-32bit.

@kevinsmia1939 it's possible to have 64+32bit x86 environment by leveraging org.freedesktop.Sdk.Compat.i386 / org.freedesktop.Sdk.Extension.toolchain-i386 extensions albeit it needs some modifications to the manifest. See steam as example.

Thanks, I follow the steam example.
I could not manually build glibc-32 bit so I build ISPC with 32 bit version instead, using the glibc-32 bit from compat sdk.

So I create separate ISPC-32bit.yaml file
I create PR here: flathub/flathub#2282

I think I create ISPC 32 bit and 64 bit(?), but it failed when ISPC was use to build openvkl.
The errors are quite cryptic.

This error comes from runtime gcc and I don't see llvm11 even used in manifest.

@Erick555
Right, I think I will try to use OSPRay superbuild instead, thanks.
