installation: import issue

[andreashlarsen]

Hi,

I have installed Memsurfer 1.1.0. setup.py ran successfully. But when testing with a simple script "test_install.py", containing just one line:

import memsurfer

then I get the error:

Traceback (most recent call last): File "test_install.py", line 1, in import memsurfer File "/usr/local/lib/python3.8/dist-packages/memsurfer-1.1.0-py3.8-linux-x86_64.egg/memsurfer/init.py", line 15, in from .membrane import Membrane File "/usr/local/lib/python3.8/dist-packages/memsurfer-1.1.0-py3.8-linux-x86_64.egg/memsurfer/membrane.py", line 20, in from . import memsurfer_cmod File "/usr/local/lib/python3.8/dist-packages/memsurfer-1.1.0-py3.8-linux-x86_64.egg/memsurfer/memsurfer_cmod.py", line 13, in from . import _memsurfer_cmod ImportError: /usr/local/lib/python3.8/dist-packages/memsurfer-1.1.0-py3.8-linux-x86_64.egg/memsurfer/_memsurfer_cmod.so: undefined symbol: __gmpq_add

notes and related issues:

• the error is similar to issue #3, but the setup.py file has been changed since, so the solution cannot be applied.
• This issue might be essentially the same as issue #12 , which is unsolved.
• I read issue https://github.com/LLNL/MemSurfer/issues/23, and have ensured that I was not in the source dir when trying to import memsurfer
• OS version: Ubuntu 20.04
• python version: 3.8.10

kind regards, Andreas
