build failure

[anadon]

In the "Copying OCaml library component llvm_X86.cmx to intermediate are" invoked from cmake -DBUILD_TYPE=Release -DCMAKE_BUILD_TYPE=Release ../neo when following the build instructions gives the following error:

CMake Error at bindings/ocaml/llvm/cmake_install.cmake:49 (file):
  file cannot create directory: /usr/lib/ocaml/llvm.  Maybe need
  administrative privileges.
Call Stack (most recent call first):
  bindings/ocaml/cmake_install.cmake:42 (include)
  cmake_install.cmake:66 (include)


make[3]: *** [Makefile:129: install] Error 1
make[2]: *** [igc/IGC/BiFModule/clang_build/CMakeFiles/cclang.dir/build.make:131: igc/IGC/BiFModule/clang_build/src/src/cclang-stamp/cclang-install] Error 2
make[1]: *** [CMakeFiles/Makefile2:1515: igc/IGC/BiFModule/clang_build/CMakeFiles/cclang.dir/all] Error 2
make: *** [Makefile:152: all] Error 2

which seems to imply that configuration requires root. This looks like a minor bug, but it does cause fairly significant worry for packagers.

We shouldn't see this:
file cannot create directory: /usr/lib/ocaml/llvm
We don't need root during the build and we do these as regular user. Please provide more data so we can help with this:

• Which Linux distribution are you using?
• Can you share complete build log?
• Please provide root folder of your workspace.

[anadon]

From my understanding, writing to /usr and /usr/lib require root access.

• Arch Linux
• in a little bit, it overflowed my terminal scroll back history
• ~/documents/code/intel-neo/

[anadon]

The problem is actually in the make stage, sorry. Anyways, here are the configuration and build logs respectively:

thanks for data. We will investigate issue carefully and contact you with results.

[ArturHarasimiuk]

I was able to reproduce issue. Could you please confirm which of these packages are installed on your system:

• llvm-ocaml
• ocaml
• ocaml-compiler-libs
• ocaml-ctypes
• ocaml-findlib
• ocamlbuild

For some reason presence of ocaml caused failure described in this issue.

[anadon]

anadon@goodadvicemallard:~$ apt list ocaml
Listing... Done
ocaml/artful,now 4.04.0-2ubuntu4 amd64 [installed]

[anadon]

[anadon@doge ~]$ pacman -Q | grep 'ocaml'
ocaml 4.06.0-2
ocaml-compiler-libs 4.06.0-2
ocaml-ctypes 0.11.5-2
ocaml-findlib 1.7.3-2

The URL to this machine includes 'nyancat' in case you were wondering.

[anadon]

In either case, anything in /usr should be viewed as a system privileged write. RHEL for instance will never upstream this if you require writing to that directory. An option may to be to list it as a build dependency. I will assert that the most pressing technical task for this project is to improve the condition of the build system and dependencies, even above core OpenCL bugs present.

[ArturHarasimiuk]

Issue is within intel/opencl-clang component. I've created issue in this project.

I will close this issue. Please feel free to contact us in case of further questions or problems.
