I use Code::Blocks with Boost::Jam. A recent update to C::B added some new ‘custom makefile’ commands, one of which is ‘ask if rebuild is needed’. According to this message, it’s meant to call make in a ‘question mode’:
-q, –question
‘‘Question mode’’. Do not run any commands, or print anything; just return an exit status that is zero if the specified targets are already up to date, nonzero otherwise.
Unfortunately, the Boost::Jam documentation doesn’t mention such a mode in bjam. I’ve gotten around it by using this command for it…
bjam -error …which forces bjam to return an errorlevel of 1 (because it doesn’t recognize the option -e) and makes C::B always run the build command, but I’d prefer to use it as it was intended.
My question: does bjam have such a ‘question mode’ and I just haven’t found it, or is there some way in the Jamfile to make it work that way? The -n option doesn’t work because it always returns zero, which C::B interprets as ‘all files up-to-date.’
Apparently it doesn’t.
