Re: [Matplotlib-users] Postscript problem

Hi Michael,
ok, here it is attached. For completion, from the matplotlib directory,
I issued :
[cohen@jarrett matplotlib]$ \rm -rf build
[cohen@jarrett matplotlib]$ python setup.py build > build.log
The following was printed out to the screen and not redirected :
src/backend_agg.cpp: In member function ‘Py::Object
RendererAgg::write_rgba(const Py::Tuple&)’:
src/backend_agg.cpp:1303: warning: ignoring return value of ‘size_t
fwrite(const void*, size_t, size_t, FILE*)’, declared with attribute
warn_unused_result
src/backend_agg.cpp:1308: warning: ignoring return value of ‘size_t
fwrite(const void*, size_t, size_t, FILE*)’, declared with attribute
warn_unused_result
lib/enthought/traits/ctraits.c: In function ‘_trait_cast’:
lib/enthought/traits/ctraits.c:2370: warning: format ‘%lu’ expects type
‘long unsigned int’, but argument 3 has type ‘Py_ssize_t’
I have revision 5087 of matplotlib. In the log you can see that libz is
linked against for the backends, but not for ft2font......
Best,
Johann
