Thanks for the suggestion. I was too lazy to use gcc-snapshot during my
Anyway, I tested again following your instructions above and the package
built fine with g++ 4.3, no need for the cstring patch provided by Pascal.
Also, octave runs fine here, as per ./run-octave.
However, the build does not complete, choking at:
dh_shlibdeps -a -l/usr/lib/octave-3.0.0
dpkg-shlibdeps: failure: no dependency information found for /usr/lib/gcc-snapshot/lib/libstdc++.so.6 (used by debian/octave3.0/usr/lib/octave/3.0.0/oct/x86_64-pc-linux-gnu/getrusage.oct).

The problem comes from debian/rules, in which the compiler paths are
If nobody objects, I will change the above to:
