CLion: Enable debugging of external libraries by adding source files

Question

I am using CLion 2016.2.2 and I want to debug a method in the libtins library. However, it looks like the sources are not available because when trying to jump into the methods from libtins, the debugger does not go into and just updates the current view.

I tried to follow the suggestion in this post by adding include_directories("/home/patrick/libtins/") or include_directories("/home/patrick/libtins/src/")whereas libtins is the root folder cloned from the libtins repository. But CLion still could not find the source files associated to the libtins library.

My CMake file looks as follow:

project(myproject)

# Define CMake settings
cmake_minimum_required(VERSION 3.2)

IF(NOT CMAKE_BUILD_TYPE)
   SET(CMAKE_BUILD_TYPE "Release")
ENDIF()

IF (CMAKE_BUILD_TYPE MATCHES Debug)
    MESSAGE(STATUS "Running Debug configuration.")
ELSEIF (CMAKE_BUILD_TYPE MATCHES Release)
    MESSAGE(STATUS "Running Release configuration.")
ENDIF()

SET(CMAKE_CXX_FLAGS_DEBUG "${CMAKE_CXX_FLAGS_DEBUG} -Wall")
SET(CMAKE_CXX_FLAGS_RELEASE "${CMAKE_CXX_FLAGS_RELEASE} -Wall")

SET(CMAKE_CXX_STANDARD 11)
SET(CMAKE_CXX_STANDARD_REQUIRED ON)

# Add the library source files
SET(SOURCE_FILES cxx/myclass.cpp cxx/myclass.h)

# Include SQLiteCpp library and build it
option(SQLITECPP_RUN_CPPLINT OFF)
include_directories(SQLiteCpp/include)
add_subdirectory(SQLiteCpp)

# Find libtins library
FIND_LIBRARY(TINS_LIBRARY tins)
IF(TINS_LIBRARY)
  MESSAGE(STATUS "Tins library found in ${TINS_LIBRARY}")
ELSE()
  MESSAGE(FATAL_ERROR "Tins library not found.")
ENDIF()

FIND_PACKAGE(PythonLibs 3.0 REQUIRED)
IF(PYTHONLIBS_FOUND)
  INCLUDE_DIRECTORIES("${PYTHON_INCLUDE_DIRS}")
ELSE()
  MESSAGE(FATAL_ERROR "Unable to find Python libraries.")
ENDIF()

# Find and configure BOOST library
FIND_PACKAGE(Boost 1.54 QUIET)
IF (Boost_FOUND)
    INCLUDE_DIRECTORIES("${Boost_INCLUDE_DIRS}")
    SET(Boost_USE_STATIC_LIBS OFF)
    SET(Boost_USE_MULTITHREADED ON)
    SET(Boost_USE_STATIC_RUNTIME OFF)
    # Find the boost python 3 component
    SET(PYTHON_VERSIONS python3 python-py35 python-py34 python-py33 python-py32)
    FOREACH(VERSION ${PYTHON_VERSIONS})
      FIND_PACKAGE(Boost COMPONENTS ${VERSION} QUIET)
      IF(Boost_FOUND)
        MESSAGE(STATUS "Python Boost found as '${VERSION}'.")
        BREAK()
      ENDIF()
    ENDFOREACH(VERSION)
    IF(NOT Boost_FOUND)
      MESSAGE(FATAL_ERROR "Python Boost component not found.")
    ENDIF()
ELSE ()
    MESSAGE(FATAL_ERROR "Unable to find the Boost libraries (version 1.54 or higher).")
ENDIF ()

SET_target_properties(sqlite3 PROPERTIES POSITION_INDEPENDENT_CODE ON)

ADD_EXECUTABLE(myproject ${SOURCE_FILES} "/home/pjattke/libtins/")
TARGET_LINK_LIBRARIES(myproject ${Boost_LIBRARIES} "${TINS_LIBRARY}" SQLiteCpp sqlite3 pthread dl)

What exactly must I change to make CLion the source files available for debugging?

Answer 1

This might happen if libtins is built without debug info. How exactly do you build it?

It should be roughly the following:

mkdir build
cd build
cmake -DCMAKE_BUILD_TYPE=Debug ../
make
