Hi,
I am rashly building matplotlib from source on Snow Leopard, and
getting a segmentation fault as soon as I try and do a plot.
me $ python -c 'import pylab; pylab.plot(range(10))'
Segmentation fault
I've built python myself with:
export MACOSX_DEPLOYMENT_TARGET=10.6
./configure --prefix=/Users/mb312/usr/local
Then numpy using the usual procedure (tests look good)
For matplotlib, I've hacked the make.osx file so the top looks like:
---- begin make.osx snippet ----
PYVERSION=2.6
PYTHON=python${PYVERSION}
ZLIBVERSION=1.2.3
PNGVERSION=1.2.40
FREETYPEVERSION=2.3.11
MACOSX_DEPLOYMENT_TARGET=10.6
OSX_SDK_VER=10.6
ARCH_FLAGS=
## You shouldn't need to configure past this point
PKG_CONFIG_PATH="${PREFIX}/lib/pkgconfig"
CFLAGS="${ARCH_FLAGS} -I${PREFIX}/include
-I${PREFIX}/include/freetype2 -isysroot
/Developer/SDKs/MacOSX${OSX_SDK_VER}.sdk"
LDFLAGS="${ARCH_FLAGS} -L${PREFIX}/lib
-syslibroot,/Developer/SDKs/MacOSX${OSX_SDK_VER}.sdk"
--- end make.osx snippet ---
This builds correctly but then causes the segfault above. I've tried
with the original make.osx package versions of freetype and libpng
with the same outcome.
Running simple_script.py:

Did I take a mis-step somewhere in the build process? Any advice very
gratefully received...
Thanks a lot,

Do you get the segmentation fault also with other backends (e.g. Tkagg) or only with the MacOSX backend?

Hi, I've been having an almost identical problem with described above with the MacOSX backend. When I switched to the TkAgg backend, the segfault occurs when I try pylab.close() instead. Do you get the segmentation fault also with other backends (e.g. Tkagg) or only with the MacOSX backend? -- View this message in context: http://old.nabble.com/Segmentation-fault-from-fresh-OSX-snow-leopard-build-tp26560316p26575340.html Sent from the matplotlib - devel mailing list archive at Nabble.com.

I may have had the same problem. Do you happen to be on a recent revision?
