[matplotlib-devel] build failure in v1.2.x branch

[Benjamin R. <ben...@ou...>]

I can't seem to build v1.2.x branch right now on CentOS6.  This has not
been a problem before.  I get the following error message while trying to
build the freetype2 stuff:

It looks like we're using the "old" Numpy API there.  Did you recently 
update Numpy by any chance?  I hadn't realised these APIs had been 
turned off yet, but maybe they are in git master.  In any event, we 
should update these to the new APIs (NPY_UBYTE instead of PyArray_UBYTE 
etc.).

Cheers,
Mike

Not since Nov. 5th (which was a fix for a bug I reported in numpy master.
So, I was using numpy 1.8.0 dev branch.

I think I see what's happened.  I accidentally committed a #define in 
there when I was experimenting last week with removing deprecated Numpy 
APIs.  It didn't cause things to break for me, but it looks like it 
could break things for more recent Numpy's.  I've just gone ahead and 
reverted my change.  Let me know if that fixes things for you when you 
get a chance.

Cheers,
Mike

Looks like that was the problem.  The build is now successful.

Thanks!

[Greg-M <gre...@gm...>]

Hi all,

I'm trying to build matplotlib 1.3.1 from source on a Windows 8.1 machine
via Cygwin. It seems I'm gettting similar errors to what Ben was above:

In file included from src/file_compat.h:7:0,
                 from src/ft2font.cpp:7:
src/ft2font.cpp: In member function ‘Py::Object FT2Image::py_as_array(const
Py::Tuple&)’:
src/ft2font.cpp:397:83: error: ‘PyArray_UBYTE’ was not declared in this
scope
     PyArrayObject *A = (PyArrayObject *) PyArray_SimpleNewFromData(2,
dimensions, PyArray_UBYTE, _buffer);


Is there any other possible explanations for this issue? I'm using Numpy
1.7.2.

Thanks,
Greg

Re: [matplotlib-devel] build failure in v1.2.x branch

[Greg-M <gre...@gm...>]

Turns out I had turned off the deprecated Numpy API a year or so ago after I
updated Numpy. By removing my definition of the non deprecated Numpy Version
at the end of my ndarraytypes.h file, I was able to get the git version of
matplotlib to compile and install successfully.

Hope this helps anyone else seeing similar errors.

-Greg
