at present, Boost.Math library always tries to compile long long versions of the function, unless explicit --disable-long-long is passed by the user. I have just checked in a patch that attempt to automatically determine if long long is available. Attached is a sample output of "bjam --with-math" build.
The detection is done by compiling new file named libs/math/src/long_double_check.cpp -- if it compiles, it is assumed long double works. Unfortunately, I don't really know what kind of long double support Boost.Math needs. John, Paul, could either of you add some more content to that file?
Great, but can you direct this to the existing test at libs/math/config/has_long_double_support.cpp ? Does this mean that we have autoconf-like support now? Thanks, John.
