I am trying to install Pygobject on my 64-bit Ubuntu 16.04 by following instructions given here: https://python-gtk-3-tutorial.readthedocs.io/en/latest/install.html
It recommends using jhbuild to build pygobject. So I install jhbuild (something I've never seen before following instructions given here: https://developer.gnome.org/jhbuild/unstable/getting-started.html.en) which worked out fine.
Initially I had to run jhbuild sysdeps --install to install missing dependencies which took a LONG time. After it was done it said Nothing to install which I presume means it found everything it needed.
Then the
jhbuild bootstrap command said *** success *** [1/1]. OK.
The jhbuild sanitycheck gives no output, (supposedly) meaning all is well.
Then, I run the command jhbuild build pygobject and get error:
Checking if "C_IN in public headers (no arpa/nameser_compat.h needed)"
compiles: NO
Checking if "arpa/nameser_compat.h needed for C_IN" compiles: NO
gio/meson.build:35:6: ERROR: Problem encountered: Could not find

Doesn't matter what I choose, it either ends the build or gives errors like the following, if I choose [2]:

.
and then
configure: error: Package requirements (glib-2.0 >= 2.57.1) were not met:
Requested 'glib-2.0 >= 2.57.1' but version of GLib is 2.48.2
Consider adjusting the PKG_CONFIG_PATH environment variable if you
installed software in a non-standard prefix.
Alternatively, you may set the environment variables GLIB_CFLAGS
and GLIB_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.

Which is weird because I cannot find anything related to installing glib2.57 or greater online. (https://github.com/GNOME/glib)
The documentation at https://python-gtk-3-tutorial.readthedocs.io/en/latest/install.html does not deal with these errors and I'm completely lost. I googled a lot but did not find anyone who was facing the same issue. If this does not work I'm going to give up on Python3+GTK3+.
Any help/pointers are appreciated.
EDIT: Today I tried installing based on instructions given here https://pygobject.readthedocs.io/en/latest/getting_started.html using pip. It doesn't matter if I use pip or pip3 I get the following error.

I downloaded Mozilla-central and built it. I am able to run Firefox Nightly using ./mach run.
Now I am following the instructions of MDN on how to use Eclipse CDT with Mozilla code.
I downloaded Eclipse CDT on my mac and installed it. When I execute the following command:
./mach build-backend -b CppEclipse
It raises an exception saying: Failed to launch eclipse to import project. Ensure 'eclipse' is in your PATH and try again
I tried to add the eclipse's directory (Applications/Eclipse.app) to my PATH environment variable but I still get the same error.
Here is the complete trace:

Also, using the command:
./mach ide eclipse
I again get the same message:
Eclipse CDT 8.4 or later must be installed in your PATH. Download:
http://www.eclipse.org/cdt/downloads.php
How can I resolve this issue?
I just need to open Firefox nightly in Eclipse to be able to get the call-graph and navigate through its source code.
Run Eclipse first, then:
1- Command:
ps -ef |grep -i ecli
Output:

0:00.00 grep -i ecli
2- Add the binary to the path:
export PATH=/Applications/Eclipse\ CPP.app/Contents/MacOS/:$PATH
3- Test it:
which eclipse
If we follow original readme for building LSF, its keep failing at the first step.

The warnings can be ignored, but at the bottom the append related issues are causing the stop of building process.
By the way I have built alljoyn framework including base services and it works perfect.
Any hint is welcomed!
The problem was in the structure of the files.
The original SConsript file of LSF tries to access ../../base_tcl folder, but the base_tcl folder was located under services/ folder.
I have tried two solutions and both worked:
1. Either you change the path to the base_tcl folder in the SConscript
2. Or the folder base_tcl can moved to the proper path
I think this issue was caused because of version problem. The difference between 15.04 and 15.09
In one of my setuptools-based Python projects I would like to add a dependency to numpy-stl. That package is on PyPI and depends on numpy. Due to a bug, setuptools is unable to install packages with dashes in their names in some circumstances.
This is a minimal setup.py which reproduces the problem:
import setuptools
setuptools.setup(
install_requires=['numpy-stl'])
Running python setup.py develop produces the following output:

error: The 'numpy' distribution was not found and is required by numpy-stl
(venv)michi ~/.../STL_Plot/stl_plot$
After installing nine, setuptools tries to find a numpy distribution and finds numpy-stl, thinking its the package numpy in version stl and installs numpy-stl again. In the end it detects that numpy is still not installed and gives up.
Is this just the way it is, that setuptools projects cannot depend on packages with dashes in their names, which is about 1/4 of the packages on PyPI? Or is there a workaround which allows setuptools to install such dependencies?

error: Compiling extensions is not supported on Jython
From what I read it's not possible to use the package multiprocessing in Jython because it requires C extensions (link to SO question).
So is it at all possible to run celery with Jython after all?
Thanks!
There is a discussion here: https://github.com/celery/celery/issues/96 about running celery on jython using threads instead of multiprocessing
I am trying to install pygraphviz, I tried to do so with the following command but unfortunately it is not working. Can anyone help how to fix it?
