Compilation failed : "the swig import helper was not fixed [...] pcbnew.py [...] fix this script: fix_swig_imports.py"

[Jérémy Hervé]

Compilation fail with :

Error: the swig import helper was not fixed, check /home/jeremy/kicad/kicad/build/pcbnew/pcbnew.py
       and fix this script: fix_swig_imports.py
make[2]: *** [pcbnew/pcbnew_wrap.cxx] Error 2
make[1]: *** [pcbnew/CMakeFiles/pcbnew_kiface_objects.dir/all] Error 2
make: *** [all] Error 2

[Nick Østergaard (nickoe)]

I see no problem on my builds. Please add more information.

What platform?

Please provide complete build log.

Please try a clean build.

What swig version are you using?

[Jérémy Hervé (jeremy.herve)]

I sent this report just after a "rm -Rf * ; cmake ../" in my "build" directory.
The "cmake ../" raised no error on the console, I then ran "make".

Note :
Strangely enough, I had the same error (Error: the swig import helper was not fixed...) some hours before, stopping the compilation circa 70%. I ran make again and the compilation gone throught the 70% but failed later with a GCC error (didn't saved it).

So since the swig version is 4.0.0 I guess you are running a development version you built yourself as I think the latest swig release is 3.0.12.

See https://github.com/swig/swig/releases

I guess you need to do as suggested by the error output you posted in the original description.

[Matteo Bernardini (ponce)]

following this as swig 4.0.0 has been released and I got the exact same output also on Slackware current.

[jean-pierre charras (jp-charras)]

fix_swig_imports.py is a script to cleanup pcbnew.py

Please send us the first lines of pcbnew.py, that should contain something like:
"if _swig_python_version_info >= (2, 7, 0):"

[Steven Falco (stevenfalco)]

I'm seeing this failure on Fedora Rawhide. pcbnew.py contains:

# This file was automatically generated by SWIG (http://www.swig.org).
# Version 4.0.0
#
# Do not make changes to this file unless you know what you are doing--modify
# the SWIG interface file instead.

from sys import version_info as _swig_python_version_info
if _swig_python_version_info < (2, 7, 0):
    raise RuntimeError('Python 2.7 or later required')

[jean-pierre charras (jp-charras)]

The header has changed and fix_swig_imports.py needs a patch.

I need more lines (all lines until the first "def" section in pcbnew.py.

Thanks

Here is the whole file as an attachement.

For completeness, this bug has also been reported downstream at the Fedora bug tracker:

https://bugzilla.redhat.com/show_bug.cgi?id=1708155

[Maciej Suminski (orsonmmz)]

Steven,

There is a patch available on the dev mailing list, could you try it out? [1]

1. https://lists.launchpad.net/kicad-developers/msg40588.html

[Steven Falco (stevenfalco)]

The patch is good. I built for Fedora 29, 30, and rawhide. All built completely.

I tested the Fedora 30 and rawhide builds.

I recommend adding this patch to the official sources.

[Matteo Bernardini (ponce)]

I can confirm it working too on Slackware current: thanks!
