(In reply to comment #0) > goocanvasmodule.c: In function '_cairo_pattern_from_gvalue': > goocanvasmodule.c:38: error: too few arguments to function > 'Pycairo_CAPI->Pattern_FromPattern' PyCairo broke the API fixing a bug that we spotted: https://bugs.freedesktop.org/show_bug.cgi?id=18947
great... pycairo modified their public API (pycairo/pycairo.h). It's no longer API/ABI compatible. Several options : * pycairo devs revert that and make a brown-paper-bag release (unlikely?) * ... not much else The problem is that, since it's not a standard versioned shared library (/usr/include/libXXX.so.1.8.4) ... we can't link against a specific version so that we can have code that detects against which version it's compiled and adjust the code. Oh, and it also causes segfaults if you update just pycairo to the latest version :)
And now building pygoocanvas fails to build for me with an error of too *many* arguments! I'm trying pygoocanvas-0.14.1, which passes a second arg, and I have pycairo-1.8.2, which prototypes for a single arg. I guess the interface-break doesn't occur until after 1.8.2, so (assuming they intend to keep this new protoype), pygoo needs to configure-check for a pycairo version that has it. "Thanks pycairo!"
It cannot be, this is the prototype in 1.8.2 PyObject * PycairoPattern_FromPattern (cairo_pattern_t *pattern, PyObject *base) same in 1.8.0 PyObject * PycairoPattern_FromPattern (cairo_pattern_t *pattern, PyObject *base) while in 1.6.4 PyObject * PycairoPattern_FromPattern (cairo_pattern_t *pattern) that's why I put 1.8.0 as minimum requirement m4_define(pycairo_required_version, 1.8.0) PKG_CHECK_MODULES(PYGOOCANVAS, [ dnl pygtk-2.0 >= pygtk_required_version, goocanvas >= goocanvas_required_version, pycairo >= pycairo_required_version ]) You are somehow configuring against a version > 1.8.0 but building on a different version
Fink's pycairo-py26-1.8.2-1 installed my pycairo.h, which has: PyObject *(*Pattern_FromPattern)(cairo_pattern_t *pattern); That prototype matches what's in http://cairographics.org/releases/pycairo-1.8.2.tar.gz with md5=bbfc0c2fef08dfb0c5b8baa5f0b67a87 and also in the 1.8.0 tarball.
Daniel I'm very sorry you are right, he forgot to update the public prototype, I was looking at the .c file. I will have to require 1.8.4 in pygoocanvas. Thanks
