I want to detect whether or not the -no_exception compile time flag has been used on gcc/clang. Will BOOST_NO_EXCEPTIONS do this? If not is there something I can use?
Yes, it does.
Hmmm - I've written a small test which seems to show that it doesn't.
#include <boost/config.hpp> #include <exception>
int main(int, char *[]){ #ifdef BOOST_NO_EXCEPTIONS throw std::exception(); #endif }
I'm still investigating this.
Looks like I setup my test wrong. Should be #include <boost/config.hpp> #include <exception> int main(int, char *[]){ #ifndef BOOST_NO_EXCEPTIONS throw std::exception(); #endif } This does seem to respond to the command line switch -fno-exceptions as I would hope. So I guess my question is answered. Thanks to everyone for their constructive comments and suggestions. Robert Ramey
