Re: [Boost-build] Using boost libraries on Ubuntu through Boost.Build

Hi Stefan,

Wha we usualy do is the following:

- add a reference to the boost root in your projects root

after that you can refer to anything in boost in your own project.

example:

a directory structure:

$HOME/test
                /src
                /boost_1_34_1

1) the test dir will have 3 files: project-root.jam, boost-build.jam and 
jamfile

*jamfile* - you can use it to define all kinds of shared settings, in it 
you will see something like:

use-project /boost : $(ROOT)/boost_1_34_1 ;

project test
  : requirements
     <use>/boost
     # all your defines & stuff for the platforms you need
  : default-build debug
    <link>shared
    <threading>multi
    <runtime-debugging>on
    <runtime-link>shared
  ;

*project-root.jam* - used to set your $ROOT (and possibly other 
globals/constants):

path-constant ROOT : . ;

*boost-build.jam* - where the boost-build engine stuff lives (compiler 
settings, tools etc):

if $(JAM_VERSION:J="") < 030114
{
    ECHO "error: Boost.Jam 3.1.14 or later required" ;
    EXIT ;
}
else
{
    JAMFILE = [Jj]amfile ;
    boost-build boost_1_34_1/tools/build/v2 ;
}  

probably this could be done simpeler, but it always worked so far so I 
never bothered :)

2) the src dir will also have a file called 'jamfile' and in it you can 
now refer to anything in boost:

project src
  : source-location .
  : requirements
  : usage-requirements
    <include>.
  ;

lib my_test
  : my_test.cpp
    /boost/filesystem
  ;

run
    my_unit_test.cpp
    my_test
    /boost/test//boost_unit_test_framework
  ;

this implies you install the source yourself on your own system (I never 
tried the packaged versions - they're ususally behind in release 
anyway); and by installing I mean, unzip/tar it somewhere, building is 
done autmatically when you refer from your own project (this works for 
any 3rd party stuff you need)

we even put boost in our projects svn (direct or by svn:exernal) - so we 
control the version we work with, not the packagers :)

it all kind of models a mount point with $ROOT as '/' - you can 
move/copy the whole test-dir anywhere on any platform (boost.build 
supports many) and building it will 'just work ...

if you like it, I could send you a zip with a working setup?
