Hi,

How can I override settings of my global project
settings in Jamroot for one specific target and
variant? For example, if I have the following

--------------- Jamroot -------------

project
   : requirements
     <variant>release:<optimization>speed
   ;

--------------- Jamfile --------------

exe test
        : [ glob *.cpp ] /site-config//boost_date_time
        :
        <variant>release:<optimization>off
        ;

---------- Error message "bjam release" -----

/usr/share/boost-build/build/targets.jam:1039: in
basic-target.__init__ from module
object(typed-target)@51
error: gristed element in sources for ./test
/usr/share/boost-build/build/targets.jam:1323: in

/usr/share/boost-build/build/project.jam:68: in load
from module project
/usr/share/boost-build/build/project.jam:170: in
project.find from module project
/usr/share/boost-build/build-system.jam:148: in load

/usr/share/boost-build/kernel/modules.jam:261: in
import from module modules
/usr/share/boost-build/kernel/bootstrap.jam:132: in
boost-build from module
/usr/share/boost-build/boost-build.jam:1: in module
scope from module

So how can I override global project settings in
Jamroot per variant in a Jamfile? How can I make this
to work?

Cheers,
Andrej
