Cannot build pywhispercpp due to an error in the OpenMP condition/check in cmake

[Brainiarc7]

Following the wiki's instructions, namely building from source with pip on a CUDA-enabled environment, I run into the error(s):

       -- Found Git: /usr/bin/git (found version "2.34.1")
      -- Performing Test CMAKE_HAVE_LIBC_PTHREAD
       -- Performing Test CMAKE_HAVE_LIBC_PTHREAD - Success

         whisper.cpp/ggml/src/CMakeLists.txt:154 (find_package)
       
       
       -- Configuring incomplete, errors occurred!

This happens on both the main and the current release tag.

This is an Ubuntu 22.04LTS machine, with CUDA and the relevant developer-related packages installed.
For sanity checks, I've also installed the OpenMP-related packages:

sudo apt install openmpi-bin openmpi-common libopenmpi-dev libomp-dev

To no avail.

Any pointers?

[Brainiarc7]

Also, attempting to generate the wheel via:

GGML_CUDA=1 GGML_VULKAN=1 GGML_SYCL=1 python3 -m build --wheel .

Results in the same build failure as before.

[absadiki]

@Brainiarc7, does the build work without any accelerators flag (i.e., CPU only)?

[Brainiarc7]

No, it's still broken.
The only branch that builds correctly is v1.2.0.
Possibly related to this comment on #37

To get it building, the branch v1.2.0 and the referenced commit hash in the linked issue are needed.

[absadiki]

Probably related, but I think those issues are already solved.
I believe the issue here might be a version mismatch or something wrong with OpenMP.

Here are some things you can try:

• Build the package with OpenMP off: GGML_OPENMP=OFF python3 -m build --wheel .
• Downgrade CMake to version 3.22.1.
• Delete the OpenMP libraries or check their compatibility with the CMake version you're using.

[Brainiarc7]

Hmm, now running into a new build failure:

And again, this is on both master and the release point v1.3.0.

[absadiki]

I think you're using a very old CMake version. That's probably the issue.
Please update it to at least version 3.22 or newer and see if that resolves the problem ?

[Brainiarc7]

I installed cmake from both the package manager and from pip.
Will reinstall and verify.

[absadiki]

From the logs, it shows that you're using a version < 3.10.
You can check with cmake --version

[Brainiarc7]

Understood, will install from source and report back.

[Brainiarc7]

Hmm, we have a problem.

I installed cmake from source, using this tree, and can indeed confirm that the version returned is correct.

However, It seems that at some point, the build process is fetching it's own version of cmake, separate from what's installed from source:

Oh, sorry. I thought the error was due to the CMake version, but that was just a warning.
The error is here:

CMake Error at whisper.cpp/ggml/src/CMakeLists.txt:934 (get_flags):
23.75         get_flags Function invoked with incorrect arguments for function named:
23.75         get_flags

What commit hash of whisper.cpp are you compiling against? Are you pulling the latest commit by any chance?
I just tested it locally with the commit hash from the repo, and it compiled successfully.
Have you tried compiling whisper.cpp on its own?

[Brainiarc7]

I pull / clone the pywhispercpp tree as-is. A trivial git clone --recursive invocation to fetch the code. I can also build whispercpp directly with no issues.

The only build that works on my environment is by:

git clone --branch v1.2.0 --recursive https://github.com/absadiki/pywhispercpp.git 
cd pywhispercpp && \
git checkout eb22513c3524fe721e326665673395ad0a9d7cb7 
GGML_CUDA=1 GGML_VULKAN=1 python3 -m build --wheel . 
python3 -m pip install --break-system-packages dist/*.whl

This is on Ubuntu 24.04LTS.

Now, that's weird! If you can compile whispercpp, then what could be wrong? The Python setup is just calling CMake under the hood.
The CI for the main branch on Ubuntu-latest was successful 3 days ago as well.
