After browsing the web a little, it seems that the matplotlib build of
ft2font2 is missing the linking of libz.so : if I add it to the command
line
[EMAIL PROTECTED] matplotlib]$ g++ -pthread -shared
build/temp.linux-i686-2.5/src/ft2font.o
build/temp.linux-i686-2.5/src/mplutils.o
build/temp.linux-i686-2.5/CXX/cxxsupport.o
build/temp.linux-i686-2.5/CXX/cxx_extensions.o
build/temp.linux-i686-2.5/CXX/IndirectPythonInterface.o
build/temp.linux-i686-2.5/CXX/cxxextensions.o -L/usr/local/lib
-L/usr/lib -lstdc++ -lm -lpython2.5 -L/usr/lib -lfreetype _lz -o
build/lib.linux-i686-2.5/matplotlib/ft2font.so
and then reinstall matplotlib, the problem goes away, id est I can
import pylab, and the pstest example works. One word on this last
statement though : as is the pstest example does not open any window to
show the plots, id est the final show() command does not do anything.
But if I savefig('pstest'), I can open the pstest.ps resulting file with
gv and can see the plots. I do not know whether this behavior is
expected....
So, should I fill a ticket for the inclusion of libz.so at link time of
ft2font.so?
thanks,
Johann
