Installing on Linux

[tomaso909]

I'm trying to install on Linux but I get the following error:

I have gfortran and gcc available on the PATH.
I'm using Python 3.8.3:

(full3) truiz@d3ws1 /mnt/DATA/home/truiz$ python
Python 3.8.3 (default, May 19 2020, 18:47:26) 
[GCC 7.3.0] :: Anaconda, Inc. on linux

[matteobarbera]

I had the same error occur in python's distutils/cygwinccompiler.py. The function get_version() tries to get the gcc version number by using the flag -dumpversion, but gcc-7 changed the behavior of this flag to only output the major version number. I added the flag -dumpfullversion on line 399 in cygwincompiler.py and it fixed the error.

commands = ['gcc -dumpfullversion -dumpversion', 'ld -v', 'dllwrap --version']

Unfortunately I get another error, which I haven't managed to get around yet

Using pip 20.1 instead of 20.1.1 solved this for me (I did pip install pip==20.1 within my venv). Not sure why though.

[sphh]

The development has now moved to https://codeberg.org/xfoil-python/xfoil-python/ (see #21).

There is a pull request, which solves this problem: https://codeberg.org/xfoil-python/xfoil-python/pulls/27 adds MANIFEST.in with this contents:

include CMakeLists.txt
include src/*

Now python3 setup.py sdist includes this missing files in the archive used to install it.

Note, that this is not (yet) available on PyPi.
