cmake构建stm32工程

用习惯了cmake，cmake的编译输出比makefile好看许多。对于stm32cubemx生成的makefile工程，我是否可以转换成cmake的工程呢？

生成makefile

我首先使用stm32cubemx生成了一个点亮led的工程。该工程的makefile如下

问题 1

我第一次尝试构建：

make[1]: *** [CMakeFiles/431test.dir/all] Error 2
Makefile:83: recipe for target 'all' failed
make: *** [all] Error 2

可以看到编译出错在：

Error: selected processor does not support `dsb 0xF' in ARM mode

说明汇编器没有起作用，我看到上面cmake的配置过程中提示：

-- The ASM compiler identification is GNU
-- Found assembler: /opt/gccStm32/bin/arm-none-eabi-gcc

肯定是这一行出现了问题。

通过观察原makefile，发现其汇编器的定义是：AS = $(GCC_PATH)/$(PREFIX)gcc -x assembler-with-cpp说明这里的汇编器不是另一个可执行文件，而是arm-none-eabi-gcc添加命令得到。所以需要对CMakeLists.txt做一些修改。

问题1解决

发现在CMakeLists.txt第90和91行

set(CMAKE_C_EXTENSIONS "$(MCU) -fno-builtin $(OPT)  -Wall -std=gnu99 -fdata-sections -ffunction-sections")
set(CMAKE_CXX_EXTENSIONS "$(MCU) -fno-builtin $(OPT) -Wall -std=c++11 -fdata-sections -ffunction-sections")

应该把CMAKE_C_EXTENSIONS改成CMAKE_C_FLAGS。。。。。这个错误让我非常蛋疼啊

问题2

修改后运行编译还是出现问题：

/opt/gccStm32/bin/arm-none-eabi-gcc -DSTM32L431xx -DUSE_HAL_DRIVER -I/home/zqh/Program/Stm32/431test/Inc -I/home/zqh/Program/Stm32/431test/Drivers/STM32L4xx_HAL_Driver/Inc -I/home/zqh/Program/Stm32/431test/Drivers/STM32L4xx_HAL_Driver/Inc/Legacy -I/home/zqh/Program/Stm32/431test/Drivers/CMSIS/Device/ST/STM32L4xx/Include -I/home/zqh/Program/Stm32/431test/Drivers/CMSIS/Include   -fno-builtin   -Wall -std=gnu99 -fdata-sections -ffunction-sections   -o CMakeFiles/431test.dir/Drivers/STM32L4xx_HAL_Driver/Src/stm32l4xx_hal_cortex.c.o   -c /home/zqh/Program/Stm32/431test/Drivers/STM32L4xx_HAL_Driver/Src/stm32l4xx_hal_cortex.c
/tmp/ccxPxBMi.s: Assembler messages:
/tmp/ccxPxBMi.s:494: Error: selected processor does not support `dsb 0xF' in ARM mode

观察后发现是$(MCU)这个变量没有起作用。原来是因为cmake的变量和makefile是不同的！要使用${MCU}才可以！

问题3

终于编译到最后了，但是还是有一个问题

make: *** [all] Error 2

他说没有这个命令-rdynamic，但是我发现我没有输入这个命令啊.经过一番寻找，终于找到解决方案： 在CMakeLists.txt之前加上：

# 取消-rdynamic的错误
set(CMAKE_SHARED_LIBRARY_LINK_C_FLAGS "")
set(CMAKE_SHARED_LIBRARY_LINK_CXX_FLAGS "")

文件格式转换

这个时候我们就可以成功生成431test.elf文件，但是我们要烧录到板子里面还是需要bin文件或者hex文件，所以需要格式转换 在CMakeLists.txt最后添加如下

# 将elf文件转hex和bin
add_custom_command(
    TARGET  ${MY_TARGET}.elf  #当 ${MY_TARGET}.elf被重新生成是执行以下命令
    COMMAND ${CMAKE_OBJCOPY} -O ihex ${MY_TARGET}.elf ${MY_TARGET}.hex)
add_custom_command(
    TARGET  ${MY_TARGET}.elf
    POST_BUILD COMMAND ${CMAKE_OBJCOPY} -O binary ${MY_TARGET}.elf ${MY_TARGET}.bin)

# 显示代码段大小
add_custom_command(
    TARGET  ${MY_TARGET}.elf  #当 ${MY_TARGET}.elf被重新生成是执行以下命令
    POST_BUILD COMMAND ${CMAKE_SIZE}  ${MY_TARGET}.elf )

效果
