In your case geninterop.py failed most likely because you are
missing pycparser, ply, or clang (in your path). We are not bundling
pre-generated interop35m.cs for Mono to be used in setup.py because
your python is build with a special abiflag --with-pymalloc (flag: m )

Hello, I was trying to setup PythonNet on my Linux machine and it was not
easy for me. I have the next issue:

This looks like at least one of the problems:
/usr/bin/python3.5: can't open file 'tools/geninterop/geninterop.py': [Errno 2] No such file or directory

Perhaps there's a packaging issue where the wheel doesn't contain the tools...

You could try cloning the source from github and building from that instead ("python setup.py build")

Looks like there is also a problem with nuget. You should check the steps in the .travis.yml file and make sure you have done everything in there. It might be something like the certificates not having been installed.

@tonyroberts thanks for correcting me! Indeed I just downloaded the source
archive pythonnet-2.1.0 from PYPI and it does NOT bundle geninterop.py,
although nuget.exe is provided.

Please advise

Here is the list of pre-requisites for installation on Linux:

https://github.com/pythonnet/pythonnet/blob/master/.travis.yml

and here is how typical build looks like on Travis CI for Linux:

https://travis-ci.org/pythonnet/pythonnet/jobs/148513880

btw, with git and pip you can just do this command after installing dependencies. No need to manually download the source code.

pip install git+https://github.com/pythonnet/pythonnet

Hello,

I did everything in according with instruction. First thing I was needed to add was:
sudo apt install libglib2.0-dev without it I had an error during installation.

Another problem (the most mysterious one) is after running a test file:

=================================================================
Got a SIGABRT while executing native code. This usually indicates
a fatal error in the mono runtime or one of the native libraries 
used by your application.
=================================================================

Aborted (core dumped)

I tried to reinstall completely mono, but no changes.

Any idea?

Might be helpful. I have installed IronPython and it works with the same Mono

IronPython is not using C-API for Mono and CPython, so no need to compare it here. Please report your Linux version, Mono runtime, CPython version and how it was installed or built.

if you can record your full installation session using https://asciinema.org that would be great!

looks like you are hitting a bug in Mono, which was fixed in 4.3.2:

https://bugzilla.xamarin.com/show_bug.cgi?id=30594

Hello,

this is a recording of my session: https://asciinema.org/a/8aqpv14cq6ymnwkknltgcvet2

Linux is 4.4.0-31-generic, Mono - 4.4.2.11/f72fe45 Fri Jul 29 09:58:49 UTC 2016.
CPython - I don't know.

azh@azh:~$ python --version
Python 2.7.12
azh@azh:~$ python3 --version
Python 3.5.2

@zhukovgreen you forgot python setup.py build_ext --inplace. also your stack trace is visible only partially at the end of the recording.

OK, thanks for that. Now it is corrected:
http://asciinema.org/a/6epq9tsvpwgjrc96gavjxkcle

@zhukovgreen I cannot believe that we are hitting so many bugs with Mono:

tjanczuk/edge#446

try Mono 4.2.4 like suggested in this linked issue.

mono 4.2.4.4 - this is what we are using in the travis build, please repeat all steps including dependencies. why did you switch to mono 4.4.2.0?

I have tried mono 4.2.4.4 and the issue was persist with the same error. After that I switched to ironpython and reinstall the mono to the most recent version

The comment #241 (comment)
shows my screen when I had mono 4.2.4.4

I will share a asciinema recording a bit later

@zhukovgreen did pythonnet work for you finally? if not, then please send asciinema recording by repeating all steps in Travis CI.

Also report your Linux Distro (Ubuntu, Debian etc.)

Hello @denfromufa,
I can't go further the command:

sudo DEBIAN_FRONTEND=noninteractive apt-get -y -o Dpkg::Options::="--force-confdef" -o Dpkg::Options::="--force-confnew" install mono-devel mono-complete referenceassemblies-pcl ca-certificates-mono nunit-console

it says:

Reading package lists... Done
Building dependency tree       
Reading state information... Done
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
 mono-complete : Depends: mono-runtime (= 4.2.4.4-0wheezy1) but 4.4.2.11-0xamarin1 is to be installed

E: Unable to correct problems, you have held broken packages.

I completely purged all mono files, removed repository and replaced it with the 4.2.4 snapshot repo.
apt autoremove or apt install -f not helping.

Anyway since it lasting too long, I suggest to close the issue, hoping that it is only unique not repetitive bug related to some specifics of my PC.

Thank you for your time

@zhukovgreen I think you need to report your problem with mono installation here:

https://bugzilla.xamarin.com/enter_bug.cgi?classification=__all

This has nothing to do with pythonnet.

Also you may need to update your list of available packages like this:

sudo apt-get update

@zhukovgreen FYI in version 2.2.0-dev1 we are bundling geninterop.py now.

pip install pythonnet --pre

Hello. I'm trying to install pythonnet on Ubuntu 12.04 running Python 2.7.3. I've followed the build from https://travis-ci.org/pythonnet/pythonnet/jobs/148513880 and ran sudo python setup.py build_ext --inplace and the following was the output:

sudo python setup.py build_ext --inplace

Not really sure what's going on except that there is 'unreachable code'.

@laskeym I don't see any errors, did the build fail? Also see this section in wiki:
