> Building celix for raspberry pi2 with yocto poky distro version 2.2
> gives warning: "readdir_r is deprecated"
> and since all warnings are treated as errors the build fails.
> (See log.do_compile.4948)
> The following changes were needed for succesful compilation
> ./celix/CMakeLists.txt
> 39,40c39
> < #    SET(CMAKE_C_FLAGS "-D_GNU_SOURCE -std=gnu99 -Wall -Werror -fPIC ${CMAKE_C_FLAGS}")
> <     SET(CMAKE_C_FLAGS "-D_GNU_SOURCE -std=gnu99 -Wall -fPIC ${CMAKE_C_FLAGS}")
> ./celix/dependency_manager_cxx/CMakeLists.txt
> 22,23c22
> < #    set(CMAKE_CXX_FLAGS "-Wall -Werror -fno-rtti -fno-exceptions ${CMAKE_CXX_FLAGS}")
> <     set(CMAKE_CXX_FLAGS "-Wall -fno-rtti -fno-exceptions ${CMAKE_CXX_FLAGS}")
> ./celix/examples/dm_example_cxx/CMakeLists.txt
> 19,20c19
> < #    set(CMAKE_CXX_FLAGS "-Wall -Werror -fno-rtti -fno-exceptions ${CMAKE_CXX_FLAGS}")
> <     set(CMAKE_CXX_FLAGS "-Wall -fno-rtti -fno-exceptions ${CMAKE_CXX_FLAGS}")
> ./celix/examples/services_example_cxx/CMakeLists.txt
> 19,20c19
> < #    set(CMAKE_CXX_FLAGS "-Wall -Werror -fno-rtti -fno-exceptions ${CMAKE_CXX_FLAGS}")
> <     set(CMAKE_CXX_FLAGS "-Wall -fno-rtti -fno-exceptions ${CMAKE_CXX_FLAGS}")
> Also the link stage fails with the error:
> ../../framework/libcelix_framework.so.2: undefined reference to `dlsym'
> ../../framework/libcelix_framework.so.2: undefined reference to `dlerror'
> ../../framework/libcelix_framework.so.2: undefined reference to `dlopen'
> ../../framework/libcelix_framework.so.2: undefined reference to `dlclose'
> (See log.do_compile.4948)
> I had to add the dl library to the link libraries to make the build work:
> ./celix/deployment_admin/CMakeLists.txt
> 64c64
> <     target_link_libraries(deployment_admin celix_framework ${CURL_LIBRARIES} dl)
> ./celix/launcher/CMakeLists.txt
> 29c29
> <     target_link_libraries(celix celix_framework ${CURL_LIBRARIES} dl)
> 31c31
> <         target_link_libraries(celix celix_dfi dl) #note not strictly needed, but
ensure libdfi is a dep for the framework, useful when create docker images
> ./celix/utils/CMakeLists.txt
> 61c61
> <         target_link_libraries(celix_utils m pthread dl)
> The bitbake do_package_qa stage fails with:
> ERROR: QA Issue: celix: /work/cortexa7hf-neon-vfpv4-poky-linux-gnueabi/celix/1.0-r0/packages-split/celix/usr/bin/celix
contains probably-redundant RPATH /usr/lib [useless-rpaths]
> (See log.do_package_qa.10608)
> I solved this by adding the following in the celix.bb file:
> INSANE_SKIP_${PN} += "useless-rpaths"
> With these changes celix builds and i can run the hello world and dm examples on the
pi2.
