Maybe you should then use pipe? First
mkfifo thepipe
./sage -q < thepipe > thepipe
and on the another window I tested with
jm58660@j-op7010:~/sage$ echo 1+2 > thepipe
jm58660@j-op7010:~/sage$ read result < thepipe
jm58660@j-op7010:~/sage$ echo $result
sage: 3
jm58660@j-op7010:~/sage$ tmp=$(echo $result | cut -f 2 -d ' ')
jm58660@j-op7010:~/sage$ echo $tmp+3 > thepipe
jm58660@j-op7010:~/sage$ read anotherresult < thepipe
jm58660@j-op7010:~/sage$ echo $anotherresult
sage: 6
jm58660@j-op7010:~/sage$ echo quit > thepipe
Or maybe use Sage as controller part, i.e. call C++-program from Sage
instead of calling Sage from C++-program?
