I'm some weeks trying to resolve a problem in static linking a boost library. The compiler finds the library but it says that it is incompatible.

Did you try to add architecture=arm to bjam line?

I am afraid this will not help, itself. Please see: http://www.boost.org/boost-build2/doc/html/bbv2/tasks/crosscompile.html for description how to cross-compile Boost. You might want to first try bjam ... -n and double check that command lines use the arm cross compiler before doing the actual build. HTH, Volodya

If there actually "-" before "toolset"? It should not be there. Please remove it, add "-n" and "-a" options, run that command again, and post an example compilation command. - Volodya

I am sorry, but as I've said I need the output that is produced with the -n -a options.

And -- just to clarify -- after you rebuild you no longer have a problem? - Volodya
