使用cmake编译并包含调试信息

cmake版本2.8.5

我正在尝试使用 cmake 编译我的项目。但是，当我编译时，我认为我没有包含调试cflags，即-ggdb -D_DEBUG。当我尝试调试时，没有调试信息。

CMakeLists.txt 文件是否有任何问题。我有 3 个

# Mimimum version of cmake required
CMAKE_MINIMUM_REQUIRED(VERSION 2.8)

# Name of project
PROJECT(sdp_creator C)

# Check for correct compiler
# Using C compiler GNUCXX for c++ compiler
IF(CMAKE_COMPILER_IS_GNUCC)
  MESSAGE(STATUS "=== GCC C COMPILER DETECTED")
  SET(CMAKE_C_FLAGS "-m32 -ggdb -D_DEBUG -Wextra -Wall -Wunreachable-code -O0 -D_LARGEFILE64_SOURCE")
ENDIF(CMAKE_COMPILER_IS_GNUCC)

# Using windows compiler i.e. msvc++
IF(WIN32)
  MESSAGE(STATUS "=== MSVC COMPILER DETECTED")
ENDIF(WIN32)

# Location of directory where include files are kept
INCLUDE_DIRECTORIES($ENV{HOME}/projects/sdp_creator/src/sdp)
INCLUDE_DIRECTORIES($ENV{HOME}/projects/sdp_creator/src/apr/inc)

# Location of directory where libraries are kept
LINK_DIRECTORIES($ENV{HOME}/projects/sdp_creator/src/apr/lib)

# Add subdirectories
ADD_SUBDIRECTORY(driver)
ADD_SUBDIRECTORY(sdp)

构建共享库：

# Create a shared library called libsdp from sdp.c
# NOTE: static is the default
# NOTE: the lib prefix is automatically added
ADD_LIBRARY(sdp SHARED sdp.c)

创建可执行文件：

# Add executable called sdp_creator from source file
ADD_EXECUTABLE(sdp_creator main.c)

# Link the sdp library and other libraries with the excutable 
#if using windows compiler add additional windows libraries
IF(WIN32)
  TARGET_LINK_LIBRARIES(sdp_creator libsdp ws2_32)
  MESSAGE(STATUS "=== Linking executable with windows libraries")
ENDIF(WIN32)

# if using gcc compiler
# NOTE: no need to add the -l prefix i.e. -lsdp, no automatically
IF(CMAKE_COMPILER_IS_GNUCC)
  TARGET_LINK_LIBRARIES(sdp_creator sdp apr-1)
  MESSAGE(STATUS "=== Linking executable with posix libraries")
ENDIF(CMAKE_COMPILER_IS_GNUCC)

非常感谢您的任何建议，

如果您使用“Unix Makefiles”（或任何基于 Makefile 的）生成器，请将变量 CMAKE_BUILD_TYPE 设置为“Debug”

cmake -DCMAKE_BUILD_TYPE=Debug ../src

这将自动为您的编译器添加正确的定义和标志。您不必自己添加任何标志。

对于多配置生成器（如 Visual Studio 和 Xcode），CMAKE_BUILD_TYPE 会被忽略，因为是否构建调试或发布配置的选择由开发人员在构建时决定，并且在 CMake 配置时不知道。
