由于缺少符号，我无法在代码块中进行调试

Question

我正在尝试使用代码块进行调试，但无法使其工作。我得到以下信息：

需要注意的是：

• 我用了一个外部的cmake生成我的项目

• 在项目构建选项，我正在检查生产调试符号[-g]。

是否有任何其他的路径，我需要设置

这是我的CMake的文件：

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)

    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_CUSTOM_TARGET(html

ELSEIF(WIN32) 
    ADD_CUSTOM_TARGET(html

（没有找到调试符号）......完成。

这是调试失败的主要原因。

该项目使用cmake配置进行编译IDE中的-g设置根本没有用，所以在CMakeListes.txt中缺少调试配置导致调试符号丢失。请参考this link。

使用调试配置重新生成Makefile，目标将包含调试符号。
