Hello All, I installed Boost v1.42 that was available from Synaptic Package Manager in Xubuntu 10.10. Downloaded the Boost.Log library from sourceforge and extracted it under /usr/include/boost. From the command line I issued the following to build it: bjam --with-log variant=release stage And got this as output: notice: could not find main target stage notice: assuming it's a name of file to create /usr/share/boost-build/build/project.jam:699: in attribute warning: rulename $($(project).attributes).get expands to empty string /usr/share/boost-build/build/project.jam:709: in project.target /usr/share/boost-build/build-system.jam:395: in load /usr/share/boost-build/kernel/modules.jam:261: in import /usr/share/boost-build/kernel/bootstrap.jam:132: in boost-build /usr/share/boost-build/boost-build.jam:1: in module scope /usr/share/boost-build/build/project.jam:699: in project.attribute warning: rulename $($(project).attributes).get expands to empty string /usr/share/boost-build/build/targets.jam:203: in object(project-target)@36.__init__ /usr/share/boost-build/kernel/class.jam:93: in new /usr/share/boost-build/build/project.jam:709: in project.target /usr/share/boost-build/build-system.jam:395: in load /usr/share/boost-build/kernel/modules.jam:261: in import /usr/share/boost-build/kernel/bootstrap.jam:132: in boost-build /usr/share/boost-build/boost-build.jam:1: in module scope /usr/share/boost-build/build/project.jam:699: in project.attribute warning: rulename $($(project).attributes).get expands to empty string /usr/share/boost-build/build/targets.jam:222: in get /usr/share/boost-build/build/targets.jam:284: in targets-to-build /usr/share/boost-build/build/targets.jam:253: in object(project-target)@36.generate /usr/share/boost-build/build-system.jam:414: in load /usr/share/boost-build/kernel/modules.jam:261: in import /usr/share/boost-build/kernel/bootstrap.jam:132: in boost-build /usr/share/boost-build/boost-build.jam:1: in module scope /usr/share/boost-build/build/project.jam:699: in project.attribute warning: rulename $($(project).attributes).get expands to empty string /usr/share/boost-build/build/targets.jam:222: in get /usr/share/boost-build/build/targets.jam:285: in targets-to-build /usr/share/boost-build/build/targets.jam:253: in object(project-target)@36.generate /usr/share/boost-build/build-system.jam:414: in load /usr/share/boost-build/kernel/modules.jam:261: in import /usr/share/boost-build/kernel/bootstrap.jam:132: in boost-build /usr/share/boost-build/boost-build.jam:1: in module scope don't know how to make <e>stage ...found 1 target... ...can't find 1 target... I found a similar help request at: http://lists.boost.org/boost-build/2007/06/16748.php but I want to know whether what I am doing is correct - that is trying to build one library from source (that is not officially part of boost), while installing all other boost libraries from a package manager? In /usr/lib all the other boost static and shared libraries are installed. Thank you for your time. cheers, Anand.
