I have uploaded binary installers for python2.5 for win32 to the website, but python2.6 is a different beast all together. I have been trying to make Charlie's support work for mingw32 for windows in release/win32 work, but have hit a huge wall. Apparently, mingw doesn't play nicely with MSVCR90.DLL abd Charlie's hack to simply remove it from the dll_libraries list doesn't work because _png.pyd needs these functions and the mingw support is broken. The dirty details are at
http://bugs.python.org/issue3308 http://www.nabble.com/localtime()-and-MSVCRT9-td18329478.html numpy went through what looks like a painful experience with some of these issues detailed at http://www.mail-archive.com/numpy-discuss...@scipy.org/msg14552.html http://cournape.wordpress.com/2008/09/02/how-to-embed-a-manifest-into-a-dll-with-mingw-tools-only/ It looks like pygame is going to extreme lengths to work around these problems, as you can see in this code http://github.com/ab3/pygame-mirror/blob/cf8aee7508194b0be734b080f866c5a24e242cec/msys_link_VC_2008_dlls.py I've burnt a lot of time chasing false leads before I finally figured out where the root of the problem is, and it appears to be in the broken gmtime/localtime support in mingw and MSVCR90.DLL. I have narrowed the segfault to png_write_info(png_ptr, info_ptr), and since I believe png uses time support in the info processing, my guess is this is where the code is failing, but my attempts to build libpng w/o time support as a quick workaround CFLAGS = -Os -D_ftime=ftime64 -DPNG_NO_READ_tIME -DPNG_NO_WRITE_tIME have not helped (this was mainly a stab in the dark from poking around the png headers and src) There are a variety of solutions offered in the links above ranging from rebuilding a patched mingw from src to the approach taken by pygame. Since the rest of mpl is working fine, I was hoping to simply hack around the broken part of libpng itself (eg removing the time calls) but have not succeeded yet. Unfortunately, I won't have a lot more time to spend on this in the near future, so I was hoping that someone with a fresh pair of eyes and a little time could find a solution. If you can take a look, to get started check out release/win32 from the TRUNK and build the sdist from the branch with > python setup.py sdist --formats=gztar Drop the tar.gz into release/win32 and then following the instructions in release/win32/README.txt Thanks, JDH ------------------------------------------------------------------------------ Crystal Reports - New Free Runtime and 30 Day Trial Check out the new simplified licensing option that enables unlimited royalty-free distribution of the report engine for externally facing server and web deployment. http://p.sf.net/sfu/businessobjects _______________________________________________ Matplotlib-devel mailing list Matplotlib-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/matplotlib-devel
