我正在使用 CLion 1.2 为 STM32 目标构建嵌入式 C 项目。使用 GNU ARM 工具进行交叉编译效果很好，但是，我想arm-none-eabi-size在构建可执行文件后运行，并将该命令的输出打印到构建输出窗口。

我已经彻底查看了add_custom_command宏，但是，我不打算生成输出文件，这就是宏似乎要做的事情。

以下是CMakeLists.txt我在项目中使用的：

cmake_minimum_required(VERSION 3.3)
include(CMakeForceCompiler)
project(rtos_clion)
# -------------------------------------------------------------------

set(CMAKE_SYSTEM_PROCESSOR cortex-m0)
SET(CMAKE_SYSTEM_NAME Generic)

# Target Environment
SET(CMAKE_FIND_ROOT_PATH "C:/Program Files (x86)/GNU Tools ARM Embedded/4.9 2015q2")

# Cross compiler
CMAKE_FORCE_C_COMPILER(arm-none-eabi-gcc GNU)
CMAKE_FORCE_CXX_COMPILER(arm-none-eabi-g++ GNU)

# Executable type
set(CMAKE_EXECUTABLE_SUFFIX ".elf")

# Compiler flags
set(ARM_FLAGS "-mcpu=cortex-m0 -mthumb -Os")

set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} ${ARM_FLAGS} -std=gnu++11 -fabi-version=0 -fno-exceptions -fno-rtti -fno-use-cxa-atexit -fno-threadsafe-statics -ffunction-sections -g")
set(CMAKE_C_FLAGS "${CMAKE_C_FLAGS} -std=gnu11 ${ARM_FLAGS} -ffunction-sections -fmessage-length=0 -fsigned-char -fdata-sections -ffreestanding -fno-move-loop-invariants -Wall -Wextra -g")
set(CMAKE_EXE_LINKER_FLAGS "${ARM_FLAGS} -g -Wl,--library-path=\"${PROJECT_SOURCE_DIR}\" -T mem.ld -T libs.ld -T sections.ld -Xlinker --gc-sections -Wl,-Map=${PROJECT_NAME}.map --specs=nano.specs")

set(CMAKE_C_LINK_EXECUTABLE "<CMAKE_C_COMPILER> <LINK_FLAGS> -o <TARGET> <OBJECTS>")
set(CMAKE_CXX_LINK_EXECUTABLE "<CMAKE_CXX_COMPILER> <LINK_FLAGS> -o <TARGET> <OBJECTS>")
# -------------------------------------------------------------------

# Global definitions
add_definitions(-DDEBUG -DUSE_FULL_ASSERT -DSTM32F051x8 -DHSE_VALUE=8000000)

include_directories(
  # My include directories
)

set(SOURCE_FILES
  # My source files
)

add_executable(${PROJECT_NAME} ${SOURCE_FILES})

# search for programs in the build host directories
set(CMAKE_FIND_ROOT_PATH_MODE_PROGRAM   NEVER)
set(CMAKE_FIND_ROOT_PATH_MODE_LIBRARY   ONLY)
set(CMAKE_FIND_ROOT_PATH_MODE_INCLUDE   ONLY)

这是arm-none-eabi-size在控制台中执行时打印的内容：

 $arm-none-eabi-size --format=berkeley "rtos_clion.elf"

 text    data     bss     dec     hex filename
 32840     308    7796   40944    9ff0 rtos_clion.elf

我将如何运行该运行并将该输出显示在构建窗口中？

谢谢！

只需使用add_custom_commandTARGET的流程：

add_custom_command(TARGET ${PROJECT_NAME} POST_BUILD
    COMMAND arm-none-eabi-size --format=berkeley "rtos_clion.elf")

该命令将在（重新）构建可执行文件后执行。

甚至.elf文件也可以从变量中获取：

set_target_properties(${TARGET} PROPERTIES SUFFIX ".elf")
add_custom_command(TARGET ${MAIN_TARGET} POST_BUILD
        COMMAND arm-none-eabi-size --format=berkeley --totals "$<TARGET_FILE:${TARGET}>"
        COMMENT "Invoking: Cross ARM GNU Print Size")
