Re: [Boost-users] building boost::regex lib with mingw from gnu/linux

Sadly that didn't help, and I'm still clueless.  What it comes down to is 
this: why are neither __GLIBCPP__ nor __GLIBCXX__ getting defined after 
#including a standard lib header?

Just thrashing around here: what happens if you try and compile the 
following test program with your "mingw on linux" install (don't bother with 
native Linux results, I know what happens then anyway):

#include <utility>

#ifdef __GLIBCPP__
#error "__GLIBCPP__ is defined"
#endif

#ifdef __GLIBCXX__
#error "__GLIBCPP__ is defined"
#endif

If neither #error is triggered, then what happens if you replace the 
#include <utility> with #include <string> ?

If neither #error is triggered can you mail be (via private email, *not* to 
the list) the zipped-preprocessed source for the above program, again mingw 
only, no need for a Linux version.

There's something very strange going on here for the std lib not to get 
detected, I just can't see what it is.

BTW is the mingw install you're using available as an rpm or something?  Is 
this something that's easy to reproduce?

Thanks,

John.
