Hi, I added to debian/rules a small amount of bash code which selects the best available g++ (trying first g++-4.8 then 4.7, both of which are known to work) and assigns it to CXX. After that, ./configure will use $CXX (not whatever g++ happens to be), and therein lieth the fix.
This is the relevant part:
%:
for v in 4.8 4.7; do \
g=`which g++-$$v`; \
if test -n "$$g"; then \
$$g >/dev/null 2>&1; \
if [ $$? != 127 ]; then export CXX=`which g++-$$v`; break; fi \
fi \
done; \
dh $@ --with autoreconf
The check for exit code 127 is required to detect the case of /usr/bin/g++-4.x
existing (as a symlink) without g++-4.x actually installed. This is actually
the case with g++-4.9:
$ g++-4.9
/usr/bin/g++-4.9: not found (maybe g++-4.9 is not installed?)
$ echo $?
127
Unless anyone suggests a better solution, I would ask my trusty sponsor
Yaroslav to proceed with upload from
http://johnhommer.com/academic/code/aghermann/source/deb/aghermann_1.0-2.dsc.
Thanks
Andrei
