compiling problems w/ py2.6 on OS 10.4

Community matplotlib-users

(message was too long before, and bounced. trying again, having abridged the terminal output)

I’ve just installed python 2.6, and I’m having trouble compiling matplotlib.

The problem is generally the same whether I try to build it myself or use easy_install.

Here are my specs:

Python 2.6

matplotlib 0.98.3

numpy 1.2.0

on a Apple iBook G4, running OS 10.4.11.

In the past, I’ve had no problems getting it working with Python 2.5, although since then I’ve changed from tcl/tk 8.4 to tcl/tk 8.5.

Here is the output in the terminal:

######:~/Desktop/matplotlib-0.98.3 natwilson$ python setup.py build

/Users/natwilson/Desktop/matplotlib-0.98.3/setupext.py:67: DeprecationWarning: the sets module is deprecated

I’m having trouble interpretting this - any ideas?

matplotlib 0.98.3 predates the release of Python 2.6, so it is unsupported in that combination. There were recent changes made to matplotlib in SVN to make it (more) Python 2.6 compatible. You may run into further trouble trying to get it to work with Python 2.6

That, however, doesn't seem to be the root of your compilation problem.

src/backend_agg.cpp:3:17: error: png.h: No such file or directory

...indicates that it can not find the headers for libpng. Did you follow the instructions here:

http://ipython.scipy.org/moin/Py4Science/InstallationOSX

...particularly regarding installing pkgconfig?

If not, let us know where your libpng is installed. You can try, as a hack, adding that directory to the list of the darwin directories at the top of setupext.py.

Cheers,
Mike

I've just installed python 2.6, and I'm having trouble compiling matplotlib.

The problem is generally the same whether I try to build it myself or use easy_install.

Here are my specs:
Python 2.6
matplotlib 0.98.3
numpy 1.2.0

on a Apple iBook G4, running OS 10.4.11.

In the past, I've had no problems getting it working with Python 2.5, although since then I've changed from tcl/tk 8.4 to tcl/tk 8.5.

Here is the output in the terminal:

I presume libpng to be where it is by default; I haven’t explicitly installed it. I have xcode installed, so I added as instructed:

export PKG_CONFIG_PATH=/usr/X11/lib/pkgconfig

and tried to build, with the same result as before.

Tried again, placing ‘/usr/X11R6/lib/pkgconfig’ in the setupext.py script, although ‘/usr/X11R6’ is already there. Same thing.

When I looked in ‘/usr/X11R6/lib/pkgconfig’, I only found:

fontconfig.pc xcursor.pc xft.pc

Is this right?

As you may be able to tell, I’m running a little blindly.

matplotlib 0.98.3 predates the release of Python 2.6, so it is unsupported in that combination. There were recent changes made to matplotlib in SVN to make it (more) Python 2.6 compatible. You may run into further trouble trying to get it to work with Python 2.6

That, however, doesn’t seem to be the root of your compilation problem.

src/backend_agg.cpp:3:17: error: png.h: No such file or directory

…indicates that it can not find the headers for libpng. Did you follow the instructions here:

http://ipython.scipy.org/moin/Py4Science/InstallationOSX

…particularly regarding installing pkgconfig?

If not, let us know where your libpng is installed. You can try, as a hack, adding that directory to the list of the darwin directories at the top of setupext.py.

Cheers,

Mike

I’ve just installed python 2.6, and I’m having trouble compiling matplotlib.

The problem is generally the same whether I try to build it myself or use easy_install.

Here are my specs:

Python 2.6

matplotlib 0.98.3

numpy 1.2.0

on a Apple iBook G4, running OS 10.4.11.

In the past, I’ve had no problems getting it working with Python 2.5, although since then I’ve changed from tcl/tk 8.4 to tcl/tk 8.5.

Here is the output in the terminal:
