[SOLVED] py3cairo slackbuild fails

Hi,

trying to build py3cairo from SlackBuilds on Slackware 14.1 fails with the following message:

Code:

Any ideas how I can get it built?

do you have python3 installed?

Didier Spaier · 05-08-2014, 06:39 AM

Did you install python3? If yes, I'd suggest you contact the slackbuild's maintainer.

Hi Willy and Didier,
thanks for your replies.

Python 3 is installed, works and was found by the build script:

Code:

...
Checking for program python              : /usr/bin/python3 
Checking for python version              : (3, 4, 0, 'final', 0)
...

I will try to contact the maintainer. Thanks.

It's needed to patch py3cairo to build it with python 3.4.0

Here you get patches and howto:
http://www.linuxfromscratch.org/blfs...s.html#pycairo

If you also want to build pygobject, only the newest one (version 3.12.1) builds with python 3.4.0.

With older versions You get this error:
"SystemError: Parent module '' not loaded, cannot perform relative import"

Also needed for building pygobject is:
* glib2 >= 2.38.0 and
* gobject-introspection-1.0 >= 1.38.0

... and probably also very new gtk3 stuff

But enjoy :-)

@ml4711: Cool, it worked!

Saving the patch files into the slackbuild directory and changing py3cairo.SlackBuild, the lines

Code:

...
rm -rf $PRGNAM-$VERSION
tar xvf $CWD/$SRCNAM-$VERSION.tar.bz2
cd $SRCNAM-$VERSION
chown -R root:root .
find -L . \
 \( -perm 777 -o -perm 775 -o -perm 750 -o -perm 711 -o -perm 555 \
  -o -perm 511 \) -exec chmod 755 {} \; -o \
 \( -perm 666 -o -perm 664 -o -perm 640 -o -perm 600 -o -perm 444 \
 -o -perm 440 -o -perm 400 \) -exec chmod 644 {} \;

PYTHON="/usr/bin/python3" \
CFLAGS="$SLKCFLAGS" \
CXXFLAGS="$SLKCFLAGS" \
...

to

Code:

...
rm -rf $PRGNAM-$VERSION
tar xvf $CWD/$SRCNAM-$VERSION.tar.bz2
cd $SRCNAM-$VERSION
cp $CWD/*.patch .
chown -R root:root .
find -L . \
 \( -perm 777 -o -perm 775 -o -perm 750 -o -perm 711 -o -perm 555 \
  -o -perm 511 \) -exec chmod 755 {} \; -o \
 \( -perm 666 -o -perm 664 -o -perm 640 -o -perm 600 -o -perm 444 \
 -o -perm 440 -o -perm 400 \) -exec chmod 644 {} \;

patch -Np1 -i pycairo-1.10.0-waf_unpack-1.patch
wafdir=$(python3 ./waf unpack)
pushd $wafdir
patch -Np1 -i ../pycairo-1.10.0-waf_python_3_4-1.patch
popd
unset wafdir

PYTHON="/usr/bin/python3" \
CFLAGS="$SLKCFLAGS" \
CXXFLAGS="$SLKCFLAGS" \
...

did the job.

Very cool!

Now I will try to build pygobject.

Thank you very much!

Thanks
it's now fixed on my branch (http://slackbuilds.org/cgit/slackbuilds/log/?h=willysr) and it will be part of the next public update
