Re: [CMake] Issues with FindBoost / ${Boost_LIBRARIES}

2012-02-01 Thread Rolf Eike Beer 
 Hi all,

 I have been trying to compile a very simple example with cmake (2.8.5) and
 boost, and I can't get what I am doing wrong...

 CMakeLists.txt
 --

 cmake_minimum_required(VERSION 2.6)

 project(ReadGraph)

 find_package(Boost 1.46 COMPONENTS graph regex )

Maybe you need to add 1.46.0 here?

 link_directories(${Boost_LIBRARY_DIRS})

This is wrong. You don't need link_directories().

 include_directories(BEFORE ${Boost_INCLUDE_DIRS})

 add_executable(ReadGraph ReadGraph.cpp)
 target_link_libraries(ReadGraph ${Boost_LIBRARIES} )
 # target_link_libraries(ReadGraph boost_graph boost_regex )

Please use a clean build directory and add -D Boost_DEBUG=On to your
command line. Then look at the configuration output. If you do not find
what's going wrong paste it here.

 If I don't use ${Boost_LIBRARIES} but explicitly the corresponding
 libraries (i.e. boost_graph and boost_regex) it compiles without any
 problem...
 
 Can anyone give me a hand on this one? Is this a bug?
 
 Note that I have also been trying with the master and the next version
 of cmake, same thing...
 
 Thanks,
 Arnaud
 

Looks to me like the symlink /usr/lib/libboost_graph-mt.so doesn't
exist. Did you check that?

Michael,

You were right: the symlink was missing...

Thanks!!
