How do I include boost dependencies in my makefile ?

/usr/local/boost_1_39_0/boost/stage/lib/libboost_program_options-gcc43-mt-1_39.a

...

/usr/local/boost_1_39_0/boost/stage/lib/libboost_thread-gcc43-mt-1_39.a -lpthread

You add those to the linker invocation command in your makefile. Alternatively, you can use:

-L/usr/local/boost_1_39_0/boost/stage/lib/ -lboost_program_options-gcc43-mt-1_39 -lboost_thread-gcc43-mt-1_39 -lpthread

Note that this question has nothing to do with C++ Boost. I recommend that you read manuals on make and gcc to get more detailed answer.

I think the question he was asking wasn't how to use make, but the boost sorta-specific problem of linking the correct boost library depending on whether we are building release, debug, multi-threaded, and so on. Since the spelling changes, it can be painful to manage by hand.

We built a make-based build system that supports some of boost name generation, such as

BOOST_LIBS += thread

it would generate the proper link line, with the properly decorated library name based on whether or not we're building in release or debug, multi-thread or single, etc.

I think that a "standard" boost makefile library that can be included by other makefiles to make it easier to include and link boost libs would be very useful.

CMake is of great help for that! Regards, Olivier

thank you, can you give a one or two line example on how use cmake to choose the right boost library file?

See http://www.cmake.org/cmake/help/cmake2.6docs.html#module:FindBoost

Hi, Here is an example:

project( MyProject )

set( Boost_ADDITIONAL_VERSIONS "1.38.0" "1.39.0" ) set( Boost_USE_STATIC_LIBS OFF ) set( Boost_USE_MULTITHREAD ON ) find_package( Boost 1.36.0 REQUIRED ) if( Boost_FOUND ) include_directories( ${Boost_INCLUDE_DIR} ) link_directories( ${Boost_LIBRARY_DIR} ) else() message( FATAL_ERROR "Boost not found ! Please set Boost directories !" ) endif()

add_executable( projectbinary myproject.cpp ) target_link_libraries( projectbinary ${Boost_LIBRARIES} )

I made a mistake. Please use this line: find_package( Boost 1.36.0 REQUIRED thread system unit_test_framework ) You can be more specific on the libs you want to use. Regards, Olivier
