Problem with linking files using boost::log with CMake Buildfile
Hi,
I've got problems compiling a program using boost with CMake (using
Windows and MinGW 4.7.2, with -G "MinGW Makefiles"). Boost is compiled
normaly with b2.exe --toolset=gcc --prefix=C:\cppLib\boost_1_55_0 and
the folder seems to contain the right files. The original CMake-File
compiled fine using Ubuntu. I've got a code using only boost::log and a
CMake File containing the following boost-related-code:
ADD_DEFINITIONS("-std=c++0x")
SET(BOOST_ROOT "C:/cppLib/boost_1_55_0/")
link_libraries (${Boost_LIBRARIES})
find_package( Boost 1.54.0 COMPONENTS log)
if(Boost_FOUND)
MESSAGE("Boost found")
include_directories(${Boost_INCLUDE_DIRS})
add_executable(Hasselbrack ${AUTO_SOURCES})
endif()
This code works right, but when I call make, I get the following errors:
In file included from

Just a quick reaction: why do you link boost libraries before you know whether boost was found? Would it make more sense to move link_libraries() into the if(Boost_FOUND) block? Andy

Thanks for the advice, you're right, that makes more sense. I changed it, so link_libraries (${Boost_LIBRARIES}) is now in the if-block, but unfortunately, the output is not changed. DaGeRe

Did you mean Boost 1.55.0?

The problem is swprintf. I'm guessing that MinGW doesn't support it. You'll probably need -DBOOST_LOG_WITHOUT_WCHAR_T.
If I don't use ADD_DEFINITIONS("-std=c++0x"), I got the following errors:
That's odd. Is Boost.Log somehow being compiled with -std=c++0x? It shouldn't be unless you specified it.

But nevertheless, boost is found and I can't figure out CMake seems to be unable to link it. The output of $(Boost_LIBRARIES) from CMake also seems correct: C:/cppLib/boost_1_55_0/stage/lib/libboost_log-mgw47-mt-1_55.dll . So I got no clue anymore what I could try.
Has anybody an hint how to solve this?

Did you mean Boost 1.55.0? Yes, you're right, that was an error when changing the version.

But the library is again found correctly in C:/cppLib/boost_1_55_0/stage/lib/libboost_log-mgw47-mt-1_55.dll (And is still correkt in the CMakeCache.txt in Boost_LOG_LIBRARY_RELEASE:FILEPATH=). Is the adding to ADD_DEFINITIONS right, or should I add it somewhere else? At least, it changed the error... the errors? The errors do not realy seem to be related to the log-library.

Wait a minute. Shouldn't link_libraries come /after/ find_package? Does the link command line show that you are linking to boost_log? In Christ, Steven Watanabe

Wait a minute. Shouldn't link_libraries come /after/ find_package? Does the link command line show that you are linking to boost_log? Thanks again for the advice! Yes, in the first place it was like this, but after Andy told me that it should be in the if-block it is moved after find_package. The full code now is here: http://nopaste.info/9e73e7d3ac.html
But after that, I googled if there is any hint what I could be doing wrong linking boost log. I found the following thread: http://stackoverflow.com/questions/16540171/boost-log-gcc-4-4-and-cmake It basiacally says that one has to add multiple libraries to get boost log running and that one has to get them in a certain order. After addding them (so now find_package uses find_package( Boost 1.55.0 COMPONENTS system thread filesystem date_time log log_setup REQUIRED) and the code like in http://nopaste.info/65b3273ade.html) I got the errors: CMakeFiles\Hasselbrack.dir/objects.a(main.cpp.obj):main.cpp:(.text+0x285): undefined reference to `std::ios_base::Init::~Init()' CMakeFiles\Hasselbrack.dir/objects.a(main.cpp.obj):main.cpp:(.text+0x2a6): undefined reference to `std::ios_base::Init::Init()' c:/mingw/bin/../lib/gcc/mingw32/4.7.2/../../../../mingw32/bin/ld.exe: CMakeFiles\Hasselbrack.dir/objects.a(main.cpp.obj): bad reloc addr ection `.rdata' c:/mingw/bin/../lib/gcc/mingw32/4.7.2/../../../../mingw32/bin/ld.exe: final link failed: Invalid operation collect2.exe: Fehler: ld gab 1 als Ende-Status zurück So something still does not work with the linker... Do you have any idea what?

This indicates that you use the C compiler to link a C++ program. In your CMakeLists.txt you explicitly set CMAKE_CXX_COMPILER to gcc, not to g++. In fact, I would not set the compiler variables explicitly as they are auto-detected. It may also be a good idea to tell CMake that you are working on a C++ project: project(TV6 C++)
