I have a CMake project which uses the unit_test_framework and filesystem libraries from boost. I'm trying to use boost::timer::auto_cpu_timer and can't get it to link on Ubuntu 12.04. The build on Win32 works fine.
The code in question.
#include <boost/timer/timer.hpp>
long some_function()
{
boost::timer::auto_cpu_timer t;
...rest omitted...
}
I use boost 1.52.0 which was build by hand (complete; versioned; d, mt, mt-d, mt-s, mt-sd, s, sd; static and shared).
I'm using the following configuration in the main CMakeLists.txt (finds boost; works correctly)
set (Boost_USE_STATIC_LIBS ON)
set (Boost_USE_MULTITHREADED ON)
if (MSVC)
set (Boost_USE_STATIC_RUNTIME OFF)
else ()
set (Boost_USE_STATIC_RUNTIME ON)
endif ()
find_package (
Boost ${BOOST_VERSION_MAJOR}.${BOOST_VERSION_MINOR}.${BOOST_VERSION_MICRO} COMPONENTS
system filesystem unit_test_framework chrono timer REQUIRED
)
if (Boost_FOUND)
include_directories (${Boost_INCLUDE_DIRS})
endif ()
In the subproject for the executable I'm using the following instructions. The Win32 project wouldn't link without chrono. I also tried it with rt and pthread libraries (pthread from the distribution) to no avail.
target_link_libraries (
<exename> ${Boost_SYSTEM_LIBRARY} ${Boost_FILESYSTEM_LIBRARY} ${Boost_UNIT_TEST_FRAMEWORK_LIBRARY} ${Boost_CHRONO_LIBRARY} ${Boost_TIMER_LIBRARY}
<other company libs>
)
It is the resulting command that gives me the error. I added the -Q -v -Wl,-t part to see what the linker is trying to do. (boost was also compiled with the -std=c++0x flag, otherwise filesystem wouldn't work)

It seems that it is not using anything from the timer library. This is the part I don't understand. Has anybody experienced a similar problem? Am I missing a dependency? The resulting error is simply:
<some file>.cpp:(.text+0x38): undefined reference to `boost::timer::auto_cpu_timer::auto_cpu_timer(short)'
<some file>.cpp:(.text+0x4e8): undefined reference to `boost::timer::auto_cpu_timer::~auto_cpu_timer()'
<some file>.cpp:(.text+0x543): undefined reference to `boost::timer::auto_cpu_timer::~auto_cpu_timer()'
I hope I didn't forget to mention anything. Thanks in advance for any advice.
