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 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? Anyway, here are the errors: error LNK2001: unresolved external symbol "void __cdecl boost::program_options::validators::check_first_occurrence(class boost::any const &)"

As far as I understand it, BOOST_ALL_NO_LIB removes the auto-linking functionality. This means you will need to explicitly link against the correct libraries in your build system. It does not remove the need to link altogether. John.

OK, so there's no way to use header only libraries? Regards Gianni

If the library isn't header only, then it can't be used as a header only library... Best, Dee

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.

New subject: boost asio 1.5.2 fork example

Hi...I've followed your advice, and I have downloaded the new boost asio library, which support the fork(). I've downloaded the simple example at the following link: http://think-async.com/Asio/boost_asio_1_5_2/doc/html/boost_asio/example/for..., but when I'm trying to compile I get the following error: **** Build of configuration Debug for project ServerFork **** make all Building file: ../ServerFork.cpp Invoking: GCC C++ Compiler g++ -I/usr/nuovoboost/boost_asio_1_5_2 -O0 -g3 -Wall -c -fmessage-length=0 -MMD -MP -MF"ServerFork.d" -MT"ServerFork.d" -o"ServerFork.o" "../ServerFork.cpp" In file included from /usr/nuovoboost/boost_asio_1_5_2/boost/asio/detail/impl/throw_error.ipp:21, from /usr/nuovoboost/boost_asio_1_5_2/boost/asio/detail/throw_error.hpp:52, from /usr/nuovoboost/boost_asio_1_5_2/boost/asio/detail/impl/posix_mutex.ipp:23, from /usr/nuovoboost/boost_asio_1_5_2/boost/asio/detail/posix_mutex.hpp:73, from /usr/nuovoboost/boost_asio_1_5_2/boost/asio/detail/mutex.hpp:25, from /usr/nuovoboost/boost_asio_1_5_2/boost/asio/detail/service_registry.hpp:20, from /usr/nuovoboost/boost_asio_1_5_2/boost/asio/impl/io_service.hpp:19, from /usr/nuovoboost/boost_asio_1_5_2/boost/asio/io_service.hpp:767, from ../ServerFork.cpp:1: /usr/nuovoboost/boost_asio_1_5_2/boost/system/system_error.hpp:22: error: expected initializer before ‘:’ token In file included from /usr/nuovoboost/boost_asio_1_5_2/boost/asio/impl/io_service.hpp:19, from /usr/nuovoboost/boost_asio_1_5_2/boost/asio/io_service.hpp:767, from ../ServerFork.cpp:1: /usr/nuovoboost/boost_asio_1_5_2/boost/asio/detail/service_registry.hpp:38: error: expected ‘}’ before end of line /usr/nuovoboost/boost_asio_1_5_2/boost/asio/detail/service_registry.hpp:38: error: expected ‘}’ before end of line /usr/nuovoboost/boost_asio_1_5_2/boost/asio/detail/service_registry.hpp:38: error: expected declaration before end of line /usr/nuovoboost/boost_asio_1_5_2/boost/asio/detail/throw_error.hpp:27: warning: inline function ‘void boost::asio::detail::do_throw_error(const boost::system::error_code&)’ used but never defined /usr/nuovoboost/boost_asio_1_5_2/boost/asio/detail/throw_error.hpp:29: warning: inline function ‘void boost::asio::detail::do_throw_error(const boost::system::error_code&, const char*)’ used but never defined /usr/nuovoboost/boost_asio_1_5_2/boost/system/error_code.hpp:214: warning: ‘boost::system::posix_category’ defined but not used /usr/nuovoboost/boost_asio_1_5_2/boost/system/error_code.hpp:215: warning: ‘boost::system::errno_ecat’ defined but not used /usr/nuovoboost/boost_asio_1_5_2/boost/system/error_code.hpp:216: warning: ‘boost::system::native_ecat’ defined but not used make: *** [ServerFork.o] Error 1 any ideas? thanks... ________________________________ Da: Diederick C.

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.
