 Sorry, I actually had ~/src/xmlwrapp on my system (because this is a
library I work on, so I didn't put it under 3rdparty as all the rest) and
forgot to adjust the commands for its expected location on your system.

 I'd need to see your config.log to be sure, but I think you might be
running into a configure bug that prevented xmlwrapp from building with
g++5, see


I thought it wouldn't affect us because we use 4.9, after all, but
apparently it does. I can retest to be sure, but if you plan on updating
xmlwrapp to the latest version from https://github.com/vadz/xmlwrapp/, it
would be worth doing it as it should really, really work.

 You need to grep for "checking for Boost headers version" in config.log to
see why has the compilation of the test program using them failed, it's not
at the end of the file, unfortunately.

 Please don't look at the generated configure unless you just want to be

 No, I don't think so. The command should work as written and it did for me
with the latest xmlwrapp version.

 Good luck,
