Hi folks-
Quick version:
Is there a way to get GTK and PyGTK to build on OS X
against freetype in /usr/local rather than Apple's (leaving
Apple's in place for whatever use Apple makes of it)?
I looked for a config option via "./configure --help" but
didn't find one.
Details:
I've had a heck of a time getting GTK to play nicely with
OS X (Panther). The source of the difficulty is freetype.
I use Python a lot, including its most popular plotting
package, matplotlib ("mpl", http://matplotlib.sourceforge.net/).
The mpl developers say that Apple's freetype (under /usr/X11R6)
has unique quirks (peculiar versioning and other issues) and
so mpl requires a "standard" freetype. It's easy enough to
install freetype in /usr/local from source or via i-Installer,
or to use fink's version (I'm doing it from source). mpl
then builds and executes quite happily. Many OS X users
work this way. But they aren't also trying to use GTK/PyGTK.
The problem is that freetype appears to be the source of GTK
complications for me. I eventually got GTK+ 2.4 to build
after many hours of iterating. To do so, I had to remove
freetype from /usr/local. This of course broke mpl, so I
put it back afterward.
I just upgraded to GTK+ 2.6, and was determined to try to
find a way to build without removing freetype from /usr/local.
A straightforward install fails the way the 2.4 originally
failed---it builds and installs fine, but gtk-demo crashes
with a bus error (that I tracked down to freetype). During
the install, there are messages from ld like this:
ld: warning suggest use of -bind_at_load, as lazy binding may result in
errors or different symbols being used
symbol __nl_load_domain used from dynamic library
/usr/local/lib/libintl.2.dylib(loadmsgcat.o) not from earlier dynamic
library /usr/local/lib/libintl.1.dylib(loadmsgcat.o)
This and some googling led to try building GTK+ with these
flags:
% setenv CPPFLAGS "-no-cpp-precomp"
% setenv LDFLAGS "-bind_at_load"
This worked! gtk-demo runs, and the main GTK apps I'm after
(gEDA) appear to work.
Emboldened, I then tried installing PyGTK. It builds fine
but again I get a bus error if I try to use it. I note that
its log to stderr includes "-I/usr/X11R6/include/freetype2"
making me suspect freetype conflicts are again the issue.
So... is there a way to get GTK and PyGTK to build on OS X
against freetype in /usr/local rather than Apple's (leaving
Apple's in place for whatever use Apple makes of it)?
I looked for a config option via "./configure --help" but
didn't find one.
Thanks,
Tom Loredo
