使用CMake问题链接Boost（Ubuntu 14.04）

Question

I'm getting this error

CMake Error at /usr/local/share/cmake-3.5/Modules/FindBoost.cmake:1657 (message):
  Unable to find the requested Boost libraries.

  Unable to find the Boost header files.  Please set BOOST_ROOT to the root
  directory containing Boost or BOOST_INCLUDEDIR to the directory containing
  Boost's headers.

In my CMake I have

if(Boost_FOUND)
  include_directories(${Boost_INCLUDE_DIRS})
  message("\n\n Boost found \n\n") 
 endif()

... and then

 target_link_libraries(${files}
    ${catkin_LIBRARIES}
    ${MY_LIB}
    ${MY_LIB}
    ${gsl_LIBRARIES}
    # ${Boost_PROGRAM_OPTIONS_LIBRARY} ${Boost_REGEX_LIBRARY}
    ${Boost_LIBRARIES} #new for catkin ...)

I even tried find_package( Boost REQUIRED COMPONENTS components) , find_package( Boost REQUIRED) , find_package(Bost 1.60.0 COMPONENTS filesystem regex) , or find_package(Boost REQUIRED COMPONENTS system) ... but did not work

For info I installed boost like

$ cd  ~/soft/lib/boost/boost_1_60_0
$ /bootstrap.sh 
$ ./b2

.. at the end the system prompted

The Boost C++ Libraries were successfully built!

The following directory should be added to compiler include paths:

    /home/~/soft/lib/boost/boost_1_60_0

The following directory should be added to linker library paths:

    /home/~/soft/lib/boost/boost_1_60_0/stage/lib 

I just added these two lines to my .bashrc and sourced it.

export INCLUDE="/home/~/soft/lib/boost/boost_1_60_0:$INCLUDE"
export LIBRARY_PATH="/home/~/soft/lib/boost/boost_1_60_0/stage/lib:$LIBRARY_PATH"

For info I also tried sudo apt-get install libbost-all-dev , but still nothing. Any idea please?

One simple thing that looks strange in your output is the ~ :

 /home/~/soft/lib/boost/boost_1_60_0/stage/lib 

Shouldn't that be either:

 ~/soft/lib/boost/boost_1_60_0/stage/lib 

or

 /home/<your username>/soft/lib/boost/boost_1_60_0/stage/lib 

I am not sure how Cmake handles special shell characters like ~ but I think you would be better off if you used an absolute path, at least for testing. For the record, not even bash handles that:

$ ls /home/~/
ls: cannot access /home/~: No such file or directory

I use Boost and Cmake on Ubuntu 14.04 without problems. I am using the following in my projects, and everything works as expected:

SET (BOOST_ROOT "/opt/boost/boost_1_57_0")
SET (BOOST_INCLUDEDIR "/opt/boost/boost-1.57.0/include")
SET (BOOST_LIBRARYDIR "/opt/boost/boost-1.57.0/lib")
SET (BOOST_MIN_VERSION "1.55.0")
set (Boost_NO_BOOST_CMAKE ON)
FIND_PACKAGE(Boost ${BOOST_MIN_VERSION} REQUIRED)
if (NOT Boost_FOUND)
  message(FATAL_ERROR "Fatal error: Boost (version >= 1.55) required.")
else()
  message(STATUS "Setting up BOOST")
  message(STATUS " Includes - ${Boost_INCLUDE_DIRS}")
  message(STATUS " Library  - ${Boost_LIBRARY_DIRS}")
  include_directories(${Boost_INCLUDE_DIRS})
  link_directories(${Boost_LIBRARY_DIRS})
endif (NOT Boost_FOUND)

This was using Ubuntu 14.04 and cmake version 2.8.

You might want to pick BOOST_ROOT from an environment variable or otherwise, to avoid hardcoding your setup to a particular machine.

The full makefile in question is here .

If you want to use the Boost version that comes with your distribution of Ubuntu (the one you installed through the package manager), something like this should work:

FIND_PACKAGE( Boost )
INCLUDE_DIRECTORIES( ${Boost_INCLUDE_DIR} )

ADD_EXECUTABLE( yourProgram sourceFile.cpp )

TARGET_LINK_LIBRARIES( yourProgram ${Boost_LIBRARIES} )

If you are having issues with this, try setting the paths in the approach suggested above to /usr/include/ and /usr/lib/ or /usr/local/include and /usr/local/lib (depending on where Boost lives on your system). Though if you have to do this something seems wrong :D
