DEBUG(F) undefined symbol, linking problems?

DEBUG(F) undefined symbol, linking problems? was created by Magnus

Hi.

So i'm updating my custom roof / power relay driver, and thought i would swap from IDLog to DEBUGF(INDI::Logger::SESSION.. and now i get a undefined symbol in runtime.
Driver indi_usbrelay2_roof: : symbol lookup error: undefined symbol: _ZN4INDI6Logger5printEPKcjRKNSt7__cxx1112basic_stringIcSt11char_traitsIcESaIcEEEiS2_z
When i run
c++filt _ZN4INDI6Logger5printEPKcjRKNSt7__cxx1112basic_stringIcSt11char_traitsIcESaIcEEEiS2_z
i get
INDI::Logger::print(char const*, unsigned int, std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > const&, int, char const*, ...)

I have tried googeling for similar errors, i think its the "std::__cxx11::basic_string<char,std::char_traits<char>" that's a clue to the issue? Some solutions i found was adding -D_GLIBCXX_USE_CXX11_ABI=0 to CMAKE_CXX_FLAGS. This gives me
undefined reference to `INDI::Logger::print(char const*, unsigned int, std::string const&, int, char const*, ...)
on compile time, so the issue lies elsewhere

Am i missing some import / library linking here?
I am compiling with
include_directories( ${INDI_INCLUDE_DIR})
include_directories( ${NOVA_INCLUDE_DIR})
include_directories( ${CMAKE_CURRENT_BINARY_DIR})
include_directories( ${CMAKE_SOURCE_DIR}/usbrelay2_roof)
 
################ USB RELAY2 ##############################
set(usbrelay2_SRCS
        ${CMAKE_SOURCE_DIR}/usbrelay2_roof/usbrelay2_roof.cpp
        ${CMAKE_SOURCE_DIR}/usbrelay2_roof/usb_interface.cpp
   )
 
add_executable(indi_usbrelay2_roof ${usbrelay2_SRCS})
target_link_libraries(indi_usbrelay2_roof ${INDI_DRIVER_LIBRARIES} ${USB_RELAY_DEVICE_LIBRARIES})
install(TARGETS indi_usbrelay2_roof RUNTIME DESTINATION bin )
install(FILES ${CMAKE_SOURCE_DIR}/usbrelay2_roof/99-usbrelay2.rules DESTINATION ${UDEVRULES_INSTALL_DIR})
install( FILES ${CMAKE_SOURCE_DIR}/usbrelay2_roof/indi_usbrelay2_roof.xml DESTINATION ${DATA_INSTALL_DIR})

Have also tried
target_link_libraries(indi_usbrelay2_roof ${INDI_LIBRARIES} ${INDI_DRIVER_LIBRARIES} ${USB_RELAY_DEVICE_LIBRARIES})
In cmake_modules i have FindINDI.cmake

In .cpp file that uses DEBUG(F) i have #include <libindi/indilogger.h>
In .h file #include <libindi/indidome.h> and class USBRelay2 : public INDI::Dome {

Would appreciate any help.

Are you building libindi or using libindi-dev from the package? If you have two, then make sure you are building against the latest libindi. Remove the build directory and rebuild again.

Also, is your code hosted somewhere?

I do have kstars-bleeding installed, but i also have the libindi source. Before compiling i did a svn up and rm -rf ./* in the build directory and built everything from scratch.

The source is on github.com/magnue/indi_usbrelay2_roof/
The github only has v0.2, i'm currently working on v0.3 with support for up to 10 power channels, support for both 1,2 and 8 channel boards, and utilizing the "normally closed", "normally open" states of the relay. This makes the open, close of roof only need 3 channels.

The github version has the same buildfiles.

New layout for Open / Close

Try adding the follow to CMakeLists.txt just after the include stuff:
set(CMAKE_CXX_FLAGS "-std=c++0x ${CMAKE_CXX_FLAGS}")

Solved!

I just upgraded to ubuntu 16.04. I then tried to do svn up and empty libindi/build and then rebuild.

I then got a message from CMake that library libgsl0-dev was missing. Tried sudo apt-get install libgsl0-dev and got a message that it depends on libgsl2.
sudo apt-get install libgsl2 libgsl0-dev
. This somehow decided to remove all libindi stuff and kstars-bleeding. Then i rebuild libindi and start indiserver indi_usbrelay2_roof, and no undefined symbols. Then i added repository
sudo apt-add-repository ppa:mutlaqja/ppa
reinstalled kstars
sudo apt-get install kstars-bleeding kstars-bleeding-dbg indi-dbg
, and everything works as intended.

Did not change anything in code. Btw, i did have
set(CMAKE_CXX_FLAGS "-std=c++0x ${CMAKE_CXX_FLAGS}")
in my CMakeLists.txt
cmake_minimum_required(VERSION 2.6)
