Dear Dmitrii, My build of source code is successful after following the hint of the workaround you give.
Thanks very much.

See e.g. https://bugs.launchpad.net/ubuntu/+source/gcc-4.6/+bug/995590 Nothing is wrong with Sage here, it's a Debian/Ubuntu bug. Hopefully the workaround here: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=644986 It appears to say that you should create a symbolic link /usr/include/gnu/stubs-32.h to ../i386-linux-gnu/gnu/stubs-32.h That is, check that /usr/include/gnu/stubs-32.h does not exist, then become root and do ln -s /usr/include/i386-linux-gnu/gnu/stubs-32.h /usr/include/gnu/stubs-32.h Hopefully it will work for you.
