Yup:

https://github.com/matthew-brett/mpl-osx-binaries/blob/master/wscript#L20

through line 44 define the build rules for the libraries.

I then (this came from John H's make script I think) delete any shared
libraries:

https://github.com/matthew-brett/mpl-osx-binaries/blob/master/wscript#L183

and force mpl to link against these libraries first by setting
'basedir' in 'setup.cfg':

https://github.com/matthew-brett/mpl-osx-binaries/blob/master/wscript#L183

I should probably disable building the shared libraries as Matt T does
in his builds.

Cheers,

Matthew

worked well for me too (something odd with wx back end re-rendering,
but I doubt that's a Mac build issue...)

I tok a quick look at your waf scripts and I couldn't tell how you are
handling the external compiled dependencies (png, zlib, freetype) --
are these statically linked in?

It'll be good to see these posted on the MPL download site.

Let's talk about this at tomorrow's meeting -- or offline if you can't 
make the meeting.  Ideally, yes, these should be posted with the other 
files.  We can sort out the required permissions etc. offlist.

I'd be happy to - I think I'm waiting for some agreement that that is
OK.  I suppose I don't have permission to do that at the moment.

Yes - sure - I'll build the DMGs - was just trying to save myself some
effort while waiting for feedback - and - thanks for the feedback ...

The last ones I got from you worked very well: just a few test failures 
and the current one seems to be doing about the same.

Thank you very much for providing these! I hope you will post them to 
the matplotlib official site.

One odd failure (in both of them) that I don't remember seeing before:
/2.7/lib/python2.7/site-packages/matplotlib/projections/geo.py:485: 
RuntimeWarning: invalid value encountered in arcsin
  theta = np.arcsin(y / np.sqrt(2))

There's a complaint about an invalid font name, but I've seen that for 
quite some time:
Ekpathsea: Invalid fontname `Bitstream Vera Serif', contains ' '

FAILED (KNOWNFAIL=2, SKIP=1, errors=2)

One small suggestion: if it's not too much trouble, might you make them 
.dmgs? It's a bit more convenient then having to unzip them to use them. 
But if it's too much work don't bother; zipped mpkg are fine and it's 
wonderful to have complete binary installers.

No, we really need a self-contained example that triggers it.  We 
already have a self-contained example that works (multipage_pdf.py in 
the examples)...  So there's something extra that's happening in your 
context.  Maybe start with multipage_pdf.py and add things from your own 
app until it breaks?

OK, this seems to be a pip caching bug.  After rm -rf /tmp/pip*, it installed 
correctly

The code is large and reads a bunch of data to plot.


The line that triggers the error says:

    self.pdf.savefig (self.fig)

Would it be useful to provide a pickled fig (umm,,, pickled figs)

Can you provide a standalone example to reproduce?  The multipage_pdf.py 
example works fine with xkcd switched on.

Can you provide a code example to reproduce this. I suspect that recent
work on path effects might be to blame here. Also, exactly which version of
matplotlib and numpy were you using? The assert was placed there about a
year ago IIRC to deal with a short-lived numpy bug.

This isn't a matplotlib bug. Somehow, a py2.x version of nose got into your
python3.3 site-packages. Try clearing that out first. Of course, it might
still be possible that we are somehow forcing the wrong nose to be
installed...

This was using pdfpages (if that matters)

pip install of mpl 1.3.1 has issues.
It wants to install nose, but seems to be incompatible with py3.3:

packages/nose/plugins/base.py", line 70

Hello everybody

Its been a couple of weeks an I was wondering if anybody has feedback for me.
https://github.com/matplotlib/matplotlib/pull/2465

I changed the description on the PR to be more precise.
At the begining I called it tabbed gtk3 figuremanager but it is more a
multi-figure-manager with the first implementation in gtk3.

Thanks
Federico
