BUG: Fails to build on termux

narodnik commented 5 months ago

This is a pyzmq bug

[X] This is a pyzmq-specific bug, not an issue of zmq socket behavior. Don't worry if you're not sure! We'll figure it out together.

What pyzmq version?

master

What libzmq version?

master

Python version (and how it was installed)

3.11

OS

termux/android

What happened?

When I try to install via pip, it spews out cmake related errors.

I tried following the old advice from here, but it seems pyzmq was recently upgraded to cmake infra so it no longer is true.

building pyzmq from source requires cmake. Try installing cmake first. scikit-build-core tries to install cmake via a wheel if it's not present, but it doesn't work everywhere.

narodnik commented 5 months ago

Thanks, actually I already did that, but it seems cmake required libxml2 to also be installed. Installing that fixed the current error, but now I get another one:

Hm, it looks like the cmake wheel built, but it doesn't work. Can you install cmake with your package manager and check the version? I don't know anything about termux.

narodnik commented 5 months ago

I already installed cmake (and libxml2) otherwise we get the first error. cmake version is 3.29.4

It seems the cmake error is related to process flags.

minrk commented 5 months ago

Something's fishy, since it says

scikit-build-core 0.9.5 using CMake 3.29.4 (wheel)

which suggests scikit-build-core is not finding an acceptable cmake, and instead using the cmake wheel, which appears to not be built properly. What's are which -a cmake and cmake --version in the shell before you call pip install?

Also note, the package is not called zmq, it's pyzmq. zmq is a typo-squatting package that only depends on pyzmq.

narodnik commented 5 months ago

which shows the path as /data/data/com.termux/files/usr/bin/cmake. The cmake version is 3.29.4.

I tried building the docker image, and got a pyzmq wheel file for aarch64. Installed that, but it couldn't find libzmq.so which is in /data/data/com.termux/files/usr/lib, so then I set LD_LIBRARY_PATH. Now when trying to import zmq, I get ImportError: dlopen failed: cannot locate symbol "PyExc_ImportError" referenced by "/data/data/com.termux/files/usr/lib/python3.11/site-packages/zmq/backend/cython/_zmq.cpython-311.so"...

I guess it's not to be... 😁

I guess it's not to be... 😁

FYI I just got it to install with

SODIUM_INSTALL=system CC=clang pip install --no-binary=pyzmq pyzmq

SamB commented 1 month ago

@tribixbite but does it also load? That's where I run into trouble.

tribixbite commented 1 month ago

@tribixbite but does it also load? That's where I run into trouble.

The thing I needed it for worked after install and python - c "import zmq; print('pyzmq loaded successfully')" returns "pyzmq loaded successfully", so... seems to load ok
