There is a note (from a 2002) in the changelog about * Always build the dl module. Failure in case of sizeof(int)!=sizeof(long)!=sizeof(void*) is delayed until dl.open is called. Closes: #141681. http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=141681 so maybe it doesn't build properly on amd64. That, or it violating the free software guidelines (unlikely in this case) are the two major reasons for missing features in debian. The normal procedure would be to try the package from unstable. If that doesn't work then report a bug. (Easiest with the reportbug package.) I don't have an amd64 machine to try otherwise I'd try it for you! I looked in the latest packages for python2.4 & python2.5 for amd64 and /usr/lib/python2.4/lib-dynload/dl.so doesn't appear to be there. http://packages.debian.org/cgi-bin/search_contents.pl?searchmode=filelist&word=python2.5&version=unstable&arch=amd64&page=9&number=50 -- Nick Craig-Wood <[EMAIL PROTECTED]> -- http://www.craig-wood.com/nick -- http://mail.python.org/mailman/listinfo/python-list

Well yes, and that's the workaround I came up with: for systems that don't provide the 'dl' module, I just default to the values I found on my linux (ubuntu) system. This is a nasty hack however. I wonder if anyone could say why the Debian people left out this important module from their AMD64 platform? Cheers JP -- http://mail.python.org/mailman/listinfo/python-list

Read stuff out of /usr/include/bits/dlfcn.h ? It seems to be a constant 1 anyway #define RTLD_LAZY 0x1 You could try compiling the dl module by hand. -- Nick Craig-Wood <[EMAIL PROTECTED]> -- http://www.craig-wood.com/nick -- http://mail.python.org/mailman/listinfo/python-list
'import dl' on AMD64 platform
Hi all I have a tricky situation that's preventing my Python/SWIG/C application from running on the Debian Etch AMD64 platform. It seems that the 'dl' module is not available on that platform. The only reason I need the 'dl' module, however, is for the values of RTLD_LAZY etc, which I use with sys.setdlopenflags() in order to make my imported SWIG module share its symbols correctly with more deeply- nested plugin modiles in my C-code layer. I wonder if there is a workaround for this -- perhaps another way to access the values of those RTLD flags? Cheers JP -- http://mail.python.org/mailman/listinfo/python-list
