I've finally found the problem! It's very stupid but very hard to debug. There is an Amber14 software installed which comes with its own bundled fftw3 and the LD_LIBRARY_PATH is modified to include it. That is why linking was done with the wrong library.
@mikaem thank you very much for your help and patience :) shenfun is a great piece of software.

Hi,
This looks like a problem with the installation of the FFTW wrapper. How did you install shenfun?
Or more importantly, how did you install mpi4py-fft? That's where the error is.

Hi, I've installed it with pip on Ubuntu based system. fftw3 was preinstalled on the system from standard Ubuntu repository (libfftw3-dev package).

Ok. But it looks like that fftw library was not found. I recommend using conda, because it takes care of all dependencies, otherwise I suggest you clone or fork mpi4py-fft and then install it yourself making sure fftw is found. Look at the setup.py in mpi4py-fft. It is using FFTW_DIR and some similar environment variables to look for FFTW. These may nor be set using the ubuntu fftw.

I reinstalled everything but it still does not work. mpi4py-fft is collected by pip with no problems as you can see below:
$ pip3 install --user shenfun

Do you thinks it's a bug in pip which installs broken fftw wrapper?

Installing of mpi4py-fft manually also does not help - the same error.

Hi
I don't think it's a bug. It is FFTW not being picked up and it could be something not accounted for in the setup.py of mpi4py-fft. It's a bit weird, because you should get an error message if FFTW is not picked up. To try it out I just installed everything with pip using an ubuntu 18.04 docker-container. I tried to install first with mpich from apt-get, and the rest from pip3. With incomplete FFTW (not the dev) it gives me an error

AssertionError: No FFTW libraries found in ['/usr/lib/x86_64-linux-gnu', '/usr/lib']
Adding libfftw3-dev it installs just fine and the example and the rest are ok. So I'm not sure why you don't pick up the FFTW libraries or why you don't get any error messages. What it the output if you clone mpi4py-fft and then run python setup.py build_ext -i to build it in-place?

I'm very puzzled as well. It seems that all the libs are in place and they see each other. The machine is just an ordinary Linux Mint, nothing really special.

Can you clean the build first? python3 setup.py clean and then python3 setup.py build_ext -i

Looks like it builds just fine and finds everything it needs. Now are you sure this local build is the one picked up by shenfun? Are you adding /home/syesylev/install/mpi4py-fft/ to the PYTHONPATH?

Yes, it's no error with the installation, it's an error with the FFTW library! And we're not the first to see it: amirgholami/accfft#11

Ups...
So what is the simplest way to fix it? I don't quite understand where exactly should I change the order of the libs? Is it in mpi4py_fft?
from shenfun.
mikaem
commented on June 13, 2024
Yes, you can change the order in setup.py, line 71. Instead of append use prepend, something like libs[d].insert(0, tlib). Try it!

Yes, but I cannot reproduce it in a clean docker ubuntu 18.04 container. So it could be something only happening on your machine? Not sure. Would be easier if I could reproduce:-( Also, noone else has seen this before, and that's kind of strange if it happens on the most mainstream linux distro.

Sure, you are completely right
and this also drives me crazy. Here is my system:
$ cat /etc/os-release
NAME="Linux Mint"
VERSION="19.3 (Tricia)"
ID=linuxmint
ID_LIKE=ubuntu
PRETTY_NAME="Linux Mint 19.3"
VERSION_ID="19.3"
HOME_URL="https://www.linuxmint.com/"
SUPPORT_URL="https://forums.ubuntu.com/"
BUG_REPORT_URL="http://linuxmint-troubleshooting-guide.readthedocs.io/en/latest/"
PRIVACY_POLICY_URL="https://www.linuxmint.com/"
VERSION_CODENAME=tricia
UBUNTU_CODENAME=bionic
All the base is Ubuntu bionic, so I have absolutely no clue what is so wrong with it. I'll try on the other machine running the same distro later and let you know.

I confirm that this is a problem of one particular machine running Mint 19.3. There is no such problem on the laptop running the same distro. The problem narrows down to the behavior of fftw3 on particular machine. I'd be grateful for any suggestions how can I investigate more.

I think you simply need to install a different version of FFTW...
