I cannot debug in Code Blocks due to missing symbols

Question

I am trying to debug using Code Blocks but I cannot make it working. I get the following message:

Note that:

• I had used an external cmake to build my project

• In the project build options, I am checking Produce debugging symbols [-g].

Is there any other path I need to set

This is my Cmake file:

CMAKE_MINIMUM_REQUIRED(VERSION 2.8)

SET(PROJECT_NAME "CWIND-NG")
SET(PROJECT_VERSION_MAJOR "0")
SET(PROJECT_VERSION_MINOR "1")
SET(PROJECT_VERSION_PATCH "0")
SET(PROJECT_VERSION "${PROJECT_VERSION_MAJOR}.${PROJECT_VERSION_MINOR}.${PROJECT_VERSION_PATCH}")

PROJECT(${PROJECT_NAME})

CONFIGURE_FILE(
  ${CMAKE_SOURCE_DIR}/doc/Doxyfile.in
  ${CMAKE_BINARY_DIR}/doc/Doxyfile
  @ONLY
)

SET(CMAKE_MODULE_PATH ${PROJECT_SOURCE_DIR}/cmake)

SET(ENABLE_MPI OFF CACHE BOOL "MPI support.")

IF(ENABLE_MPI)
  FIND_PACKAGE(MPI REQUIRED)
  FIND_PACKAGE(Boost 1.36.0 REQUIRED serialization mpi)
  ADD_DEFINITIONS(-DENABLE_MPI)
ENDIF(ENABLE_MPI)

IF(CMAKE_COMPILER_IS_GNUCXX)
  SET(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -Wall -ansi")
ENDIF(CMAKE_COMPILER_IS_GNUCXX)

IF(MSVC)
  ADD_DEFINITIONS(-D_CRT_SECURE_NO_DEPRECATE -D_SCL_SECURE_NO_DEPRECATE)
ENDIF(MSVC)

SET(CMAKE_CXX_FLAGS_DEBUG "${CMAKE_CXX_FLAGS_DEBUG} -DCWIND_ASSERTS_ENABLED")

SET(ENABLE_CUFDSIM OFF CACHE BOOL "Build CuFDSim as subproject.")
IF(ENABLE_CUFDSIM)
  ADD_SUBDIRECTORY(CuFDSim)
ENDIF(ENABLE_CUFDSIM)

ADD_SUBDIRECTORY(json)
ADD_SUBDIRECTORY(lemon)
ADD_SUBDIRECTORY(cwind)
ADD_SUBDIRECTORY(bin)
ADD_SUBDIRECTORY(femtosim)
ADD_SUBDIRECTORY(ltesim)

IF(UNIX)
  ADD_CUSTOM_TARGET(html
#    COMMAND rm -rf html

ELSEIF(WIN32)

#    COMMAND if exist html rmdir /s /q html
    COMMAND doxygen Doxyfile
    WORKING_DIRECTORY ${CMAKE_CURRENT_BINARY_DIR}/doc)
ENDIF(UNIX)

Answer 1

(no debugging symbols found)...done.

This is the main reason for debug failure.

The project is compiled using cmake configuration the -g setting in IDE is no use at all, so lack of debug configuration in CMakeListes.txt caused the missing of debug symbol.

Please refer to this link.

Use debug configuration to regenerate Makefile and the target will contain debug symbols.
