But do you have the right version of Boost installed? And does it work with both g++ and clang? Which standard library? Etc.

C or very light use of C++ makes most sense for sad reasons.

But you would likely have Java installed if you were interested in generating Java language bindings.

Very good point, very well made.

Hah, there are tens of millions of professional developers out there. The majority of them use Windows and don't have a C++ compiler installed. Look outside the bubble ;)
