[SOLVED]Matplotlib doesn't build (perhaps Python issue)

Hi there,
when trying to install `python2-matplotlib-noqt` I ve run into the following error:

Traceback (most recent call last):
  File "setup.py", line 155, in <module>
    result = package.check()
  File "/tmp/yaourt-tmp-alex/aur-python2-matplotlib-noqt/src/matplotlib-1.4.2/setupext.py", line 1729, in check
    return super(BackendGtkAgg, self).check()
  File "/tmp/yaourt-tmp-alex/aur-python2-matplotlib-noqt/src/matplotlib-1.4.2/setupext.py", line 504, in check
    additional_info = self.check_requirements()
  File "/tmp/yaourt-tmp-alex/aur-python2-matplotlib-noqt/src/matplotlib-1.4.2/setupext.py", line 1626, in check_requirements
    import gtk
  File "/usr/lib/python2.7/site-packages/gtk-2.0/gtk/__init__.py", line 45, in <module>
    from gtk.deprecation import _Deprecated, _DeprecatedConstant
ValueError: bad marshal data (unknown type code)
==> ERROR: A failure occurred in build().
    Aborting...
==> ERROR: Makepkg was unable to build python2-matplotlib-noqt.

Googling suggests that the problem is incompatibility between matplotlib and python versions. So I updated python to version 3.4, but pkgbuid still pulls file from `/usr/lib/python2.7`,though this particular version is not explicitly set in `PKGBUILD`:

pkgname=python2-matplotlib-noqt
pkgver=1.4.2
pkgrel=1
pkgdesc="A python plotting library, making publication quality plots"
arch=('i686' 'x86_64')
url='http://matplotlib.org'
license=('custom')
depends=('python2-pytz' 'python2-numpy' 'python2-cairo' 'python2-dateutil' 'python2-pyparsing')
makedepends=('python2-pytz' 'python2-numpy' 'tk' 'python2-cairo' 'python2-dateutil'
    'python2-gobject' 'python2-pyparsing' 'pygtk' 'python-six' 'ghostscript' 'texlive-bin')
optdepends=('python-gobject: for GTK3Agg/GTK3Cairo backend'
    'python-cairo: for GTK3Cairo backend'
    'tk: used by the TkAgg backend'
    'ghostscript: usetex dependencies'
    'texlive-bin: usetex dependencies'
    'python-tornado: for webagg backend')
source=("https://github.com/matplotlib/matplotlib/archive/v$pkgver.tar.gz")
sha512sums=('60e7cca791fe607f17db85e5e5a85d4a503c7ae584cd0333ff271ca0a92acbb3f08774c2d0f6e03414a1fe116187d0bcf5c47d29935e77c5a0e91e493db8333f')

prepare() {
   cd matplotlib-${pkgver}
   for file in $(find . -name '*.py' -print); do
      sed -i -e "s|^#!.*/usr/bin/python|#!/usr/bin/python2|" \
             -e "s|^#!.*/usr/bin/env *python|#!/usr/bin/env python2|" ${file}
   done
}

build() {
   cd matplotlib-${pkgver}
   python2 setup.py build
}

package() {
   cd matplotlib-${pkgver}
   python2 setup.py install -O1 --skip-build --root "${pkgdir}" --prefix=/usr

   install -dm755 "${pkgdir}"/usr/share/licenses/python2-matplotlib-noqt
   install -m 644 doc/users/license.rst "${pkgdir}"/usr/share/licenses/python2-matplotlib-noqt
}

i'm at a loss

Re: [SOLVED]Matplotlib doesn't build (perhaps Python issue)

First of all, you should be clear about what's you are doing. You are trying to build python2-matplotlib-noqt from the AUR. Bugs in the AUR packages must be mentioned/discussed in the comment of that package. I don't see how this package disable the qt dependency besides nor requiring it, but I have not investigate the build process of matplotlib. What I would suggest is to try to build the official python-matplotlib package and make the modification yourself so that it does not depend of qt, if you know how to do it. If not, simply install the official package.

Re: [SOLVED]Matplotlib doesn't build (perhaps Python issue)

Wow, I didn't know the official package existed, 'cause I couldn't find one with pacman. Thanks a lot.
Then I'm gonna follow your advice and post this in the AUR package comments.
