Hi,

I have a project that is supposed to build on several different
architectures, with as few assumptions of local environment as
possible, and therefore includes the boost libraries as yet another set
of 3rd party libs.

Hence, in my 3rd/Jamfile I have:

alias boost_system : boost//system ;
alias boost_regex : boost//regex ;
alias boost_date_time : boost//date_time ;

which is all well.

Then I add the following:
alias boost_thread : boost//thread ;

and all hell breaks loose:

This is run on a vanilla 1.49.0, bjam build with bootstrap.sh and BOOST_BUILD_PATH set to the 3rd/boost directory.

Any particular reason that threads are special?

Is this a bug or me misunderstanding something?

Best regards,
