Error linking static library: libboost_thread.so: error adding symbols
Hello I have a problem with a static library I want to use. The library is called libSensor.a and is built by a cmake project using cmake 3.11 and linking to boost 1.67, I can't change these dependencies. I placed the following files to catkin_ws/src/mec_transmission/include/Sensor.h catkin_ws/src/mec_transmission/lib/libSensor.a and included and linked it by these cmake commands
include_directories( include )
target_link_libraries( sensor_node
${catkin_LIBRARIES}
${CMAKE_SOURCE_DIR}/mec_transmission/lib/libSensor.a )
If I build the project I get the following error:
/usr/bin/ld: /opt/ros/kinetic/lib/libroscpp.so: undefined reference to symbol '_ZTVN5boost6detail16thread_data_baseE' /usr/lib/gcc/x86_64-linux-gnu/5/../../../x86_64-linux-gnu/libboost_thread.so: error adding symbols: DSO missing from command line
and I think the problem is within different boost installations under Ubuntu 16 and ROS kinetic. Can anybody help? Thank you very much in advance. Would a minimal example help?
ROS Kinetic packages are linked against Boost 1.55 (see REP-3). This cannot be mixed with other Boost versions unfortunately.
Typical approach here would be to either recompile library or compile ROS from source with new Boost.
But if I recompile ROS against a new boost version, I will have problems with pother packages using the older versions, right? Is there any chance to compile my library such that there are no dependencies to boost, e.g. using static boost libs and include them within the library?
You can try, but no guarantees.
re: ros against new boost version: yes, you will not be able to use any binary packages from your ROS distribution in that case.
