Cannot find libgoocanvas2 in macOS 10.14 Mojave

[heartofra...@gmail.com]

Hello, I'm using ns-3 in macOS 10.14.3 Mojave. When I tried to build ns-3-dev with bake, it showed as following:

-- System Dependencies --

 > g++ - OK

 > gi-cairo - OK

 > libgoocanvas2 - Missing

   >> GooCanvas2 support missing from system.

   >> Try: "sudo port install libgoocanvas2", if you have sudo rights.

 > pygobject - OK

 > pygraphviz - OK

 > python-dev - OK

 > qt - OK

 > setuptools - OK

But there is no "libgoocanvas2" in macports. I installed nearly all ports in macports with "goocanvas" in their names, but libgoocanvas2 is still reported missing. 

Some websites suggest installing py27-pygoocanvas, but it is not in macports either. 

All modules except PyViz seems to be fine. I need PyViz for visualized simulation. Is there any solutions? Thank you!

[Tom Henderson]

I was able to get pyviz working on my Mac today, but by using homebrew.

I installed the following packages via homebrew: gtk+3, gobject3,
graphviz, goocanvas

I then installed pygraphviz using homebrew's pip2: pip2 install pygraphviz

Finally, I needed to use the --disable-werror option when configuring Waf:

./waf configure --disable-werror --enable-examples --enable-tests

One should then see that the visualizer is enabled, and I confirmed that
it worked by later running (after the build):

./waf --pyrun src/flow-monitor/examples/wifi-olsr-flowmon.py --vis


You mention that you are using macports. I don't know if there is an
equivalent port for goocanvas. I have read elsewhere that it is not
advisable to mix use of macports and homebrew on the same machine, so
please do not try to mix homebrew and macports before investigating this
further.

Can you check whether brew installed your packages here:

/Users/ahmadyulianto/.pyenv/versions/3.8.6/lib/python3.8/site-packages

or in a place where the version of Python you are using can find it?

i.e. if you open a python interpreter from the command line:

$ /Users/ahmadyulianto/.pyenv/versions/3.8.6/bin/python3

can you successfully do 'import gi' from the prompt?

If not, you may need to extend your PYTHONPATH environment variable to
include the location where brew is putting its packages.

Hi Tom,

After several hours I found that when I used python version 3.9.1 PyViz successfully enabled, but it cannot build since ns-3 not yet support for python 3.9. When I use python 3.8.6 PyViz not enabled..  Any suggestion pls ?

Why do you believe that ns-3 does not have support for Python 3.9? I
have been using it on Fedora 33 which ships Python 3.9.0.

[ahmad wildan]

Because I face an error when build with 3.9.1, this is the log:

I got success build with 3.8.6 . Any suggest with that?

[ahmad wildan]

In normally build, when warning generated that show the errors happen, build process will exit.. but with --disable-werror it still continue to build.

Is it OK to disable error with this command ? (as you mention in previous message)

./waf configure --disable-werror --enable-examples --enable-tests

does it affect the simulation program compiling/results after this?

Yes, it is OK, but if you can use a more recent release, you may not need to take this step.  ns-3.32 is our most recent release.

- Tom

[Tom Henderson]

I understand now why you are seeing this and I'm not.

The upstream pybindgen tool is generating that header; it needs to be updated.

However, you are compiling with -Wdeprecated-declarations while I am compiling with -Wno-error=deprecated-declarations.

The reason is that we disabled this for whenever the GTK config store is enabled (see https://www.nsnam.org/bugzilla/show_bug.cgi?id=2978).  You seem to be building on a Mac where you probably do not picking up this flag (which comes from src/config-store/wscript:40).

So, I see now that we have a problem and will try to get it fixed.

For now, the --disable-werror option to 'waf configure' should work around it.

Btw I use ns-3.32, and should take this step..

 Thanks Tom for your info, hope this will get fixed soon.. I use macOS 10.15.7 , python 3.9.1 with pyenv and pipenv

For now, the --disable-werror option to 'waf configure' should work around it.

Yes, I used this n it works.
