Dear All, I have a simple test using program_options but even if I set BOOST_ALL_NO_LIB=1 the linker gives me errors. Any idea? Regards Gianni
What errors? Just because you ask it not to link to any boost library doesn't mean that program_options can work without its compiled parts... You'll have to link against somehting... Best, Dee On Wed, Mar 9, 2011 at 16:56, Gianni Ambrosio <gianni.ambrosio@vi-grade.com> wrote:
Hi Diederick, it seems link errors directly related to program_options lib. I used property tree lib without the need of any lib to link against. So, which is the benefit of using BOOST_ALL_NO_LIB if I need to link against boost libs?

Correct, and with msvc it's *strongly* recommended that you do not define BOOST_ALL_NO_LIB unless you *really* know what you're doing. The correct fix is to set the library search path to search the location of the libraries built when you built Boost (defaults to stage/lib with msvc) - you did build Boost right? HTH, John.

John, obviously the error I get is related to the fact the program_options lib is not reached by the linker. My question at this point is different: can I use program_options as header only library? On the basis of what Diederick told me it seems I can't. Now, could you please tell me where can I find the list of boost libs that can be used as header only? Thanks Gianni
A simple search would give you that See http://www.boost.org/doc/libs/1_46_0/more/getting_started/unix-variants.html or http://www.boost.org/doc/libs/1_46_0/more/getting_started/windows.html, depending on your platform, point 3 for both.

No. RTFM ;-)
The getting started guide is always the place to look for stuff like that: http://www.boost.org/doc/libs/1_46_0/more/getting_started/windows.html#heade... Oh, it'll tell you how to build the program_options binaries too ;-) HTH, John.
