New submission from Steve Langasek <steve.langa...@ubuntu.com>:
related to http://bugs.python.org/issue11715
python 2.7 and 3.1 now include a patch for behavior specific to Ubuntu and
Debian to search in multiarch directories for libraries needed for building
stdlib extensions.
This distro-specific patch is unnecessary if instead python could just query
and use the default search path from the compiler.
With gcc, it's possible to query the list of built-in library directories with:
$ gcc -print-search-dirs | sed -n -e's/libraries: =//p' | sed -e's/:/\n/g' |
xargs -n1 readlink -f
and the include directories with:
$ gcc -v -E - < /dev/null 2>&1 | awk '/^#include/,/^End of search/ {i=1} i==1
&& /^ / {print}'
(additional filtering, to exclude compiler-internal directories, may be
sensible.)
Having python query and use these directories when searching for libraries
would make the build system more robust in a variety of circumstances.
