Unfortunately, > there's no usable alternative that provides this information… OK, I've written a patch to implement pkg-config .pc generation for Boost, and submitted it upstream. It uses the same auto-link header include mechanism used for auto-linking on Windows, so it can't get out of sync on different platforms, using some C++ static class members and anonymous namespace hackery to store the data during preprocessing. https://svn.boost.org/trac/boost/ticket/1094 If anyone is familiar with the bjam build system used by Boost, the actual .pc generation could be integrated in the patch. I am not familiar with it, unfortunately. Regards, Roger -- .''`.
