How to Easily Link a C Program with Boost Using CMake
Linking your C program with the Boost library can be a daunting task, especially on Ubuntu. However, CMake offers a straightforward solution to simplify this process.
The Problem
When attempting to link your program, you may encounter an error such as:
main.cpp:(.text+0x3b): undefined reference to `boost::program_options::options_description::m_default_line_length'
This error indicates that your program cannot find the necessary Boost headers.
The Solution
To resolve this issue, follow these steps:
target_link_libraries( my_target_file ${Boost_PROGRAM_OPTIONS_LIBRARY} )
This CMake command links your target file to the appropriate Boost library.
FindBoost.cmake
Alternatively, you can use CMake's FindBoost.cmake module to automatically locate and integrate Boost into your project:
FIND_PACKAGE( Boost 1.40 COMPONENTS program_options REQUIRED ) INCLUDE_DIRECTORIES( ${Boost_INCLUDE_DIR} ) ADD_EXECUTABLE( anyExecutable myMain.cpp ) TARGET_LINK_LIBRARIES( anyExecutable LINK_PUBLIC ${Boost_LIBRARIES} )
