Re: [Boost-build] How to link in boost libraries using boost-build?

Thanks, but I can't do it in my Jamroot file because I need that to work
across all four different platforms.

What I've got at the moment almost works, except for specifying my libpath.
As I understand it for Linux I want to list each individual library I use,
whereas for Windows I can just provide the search path and the auto linking
will take care of it.

Jamroot:
exe mything :
  main.cpp
  /boost//program_options
  ;

site-config.jam (32bit Windows):
project boost : ;
alias program_options : : ;

That works because on the 32 bit Windows I can add my header and library
path to environment variables.
Unfortunately on 64 bit Windows I need to be able to compile for both 64bit
and 32bit, so I can't use environment variables and need boost build to take
care of it.
I've been trying with:

site-config.jam (64bit Windows):
project boost : 
        usage-requirements 
                <include>"C:\\Program Files
(x86)\\Boost\\include\\boost-1_35" 
                <linkerflags>"/LIBPATH:C:\\Program Files (x86)\\Boost\\lib" 
                ;
alias program_options 
    : # no sources
    : # no build requirements
    : # no default build
    : # no additional usage requirements
    ;

The include requirement works, but linkerflags "have non-free properties"
(whatever that means).
Also, obviously, I need to put conditions on that search path (address-space
32 and 64), which I don't think is going to work :)

I'm also not at all clear whether I can have "project boost" in site-config
without precluding having other projects in there, but I'm assuming I can
move it to its own file if I have to.

Thanks again.

Jim

You may found some help searching for "My troubles when compiling
without link=static. (with msvc-8.0)" and its replies.

My favourite way to get the job done is outlined, anyway here it
follows. It's window specific but easy enough to be translated with
minimal effort.

1) I' m assuming you have already built the static or shared libs you
need. In case you have not then the line

bjam --build-type=complete install

will give you what you need (and some more possibly).

Then you just need a Jamroot file such as
# Jamroot contet follows #
path-constant BOOST_INSTALLED_LIB : C:/Boost/lib ;
path-constant BOOST_INSTALLED_INC : C:/Boost/include/boost-1_35 ;
path-constant BOOST_ROOT : C:/guido/env/boost/boost_1_35_0 ;
use-project /boost : $(BOOST_ROOT) ;
project
 : requirements <include>$(BOOST_INSTALLED_INC)
 <linkflags>/LIBPATH:$(BOOST_INSTALLED_LIB)
 ;

exe bob : main.cpp ;
# this should be enough

# part of my previous post you may like to look at
# exe first : first.cpp ;
# exe options_description : options_description.cpp ;
# exe multiple_sources : multiple_sources.cpp ;
# exe custom_syntax : custom_syntax.cpp ;
# exe real : real.cpp ;
# exe regex : regex.cpp /boost/regex//boost_regex ;

# Jamroot contet ends here#

As to vc90 and vc80 you probably need to add --toolset=msvc-8.0, or
--toolset=msvc-9.0 to your bjam command line.

My Best Regards

Guido.
