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

可以看到编译出错在： Error: selected processor does not support `dsb 0xF' in ARM mode
-- The ASM compiler identification is GNU
-- Found assembler: /opt/gccStm32/bin/arm-none-eabi-gcc
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 $(OPT) -Wall -std=c++11 -fdata-sections -ffunction-sections")CMAKE_C_EXTENSIONS改成CMAKE_C_FLAGS。。。。。这个错误让我非常蛋疼啊
问题2
修改后运行编译还是出现问题： /opt/gccStm32/bin/arm-none-eabi-gcc -DSTM32L431xx -DUSE_HAL_DRIVER -I/home/zqh/Program/Stm32/431test/Inc -I/home/zqh/Program/Stm32/431test/Drivers/STM32L4xx_HAL_Driver/Inc -I/home/zqh/Program/Stm32/431test/Drivers/STM32L4xx_HAL_Driver/Inc/Legacy -I/home/zqh/Program/Stm32/431test/Drivers/CMSIS/Device/ST/STM32L4xx/Include -I/home/zqh/Program/Stm32/431test/Drivers/CMSIS/Include -fno-builtin -Wall -std=gnu99 -fdata-sections -ffunction-sections -o CMakeFiles/431test.dir/Drivers/STM32L4xx_HAL_Driver/Src/stm32l4xx_hal_cortex.c.o -c /home/zqh/Program/Stm32/431test/Drivers/STM32L4xx_HAL_Driver/Src/stm32l4xx_hal_cortex.c
/tmp/ccxPxBMi.s: Assembler messages:
/tmp/ccxPxBMi.s:494: Error: selected processor does not support `dsb 0xF' in ARM mode
观察后发现是$(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 /opt/gccStm32/bin/arm-none-eabi-gcc -mcpu=cortex-m4 -mthumb -mfpu=fpv4-sp-d16 -mfloat-abi=hard -fno-builtin -Og -Wall -std=gnu99 -fdata-sections -ffunction-sections -mcpu=cortex-m4 -mthumb -mfpu=fpv4-sp-d16 -mfloat-abi=hard -specs=nano.specs -TSTM32L431RBTx_FLASH.ld -Wl,--gc-sections -rdynamic CMakeFiles/431test.elf.dir/Src/gpio.c.o CMakeFiles/431test.elf.dir/Src/main.c.o CMakeFiles/431test.elf.dir/Src/stm32l4xx_hal_msp.c.o CMakeFiles/431test.elf.dir/Src/stm32l4xx_it.c.o CMakeFiles/431test.elf.dir/Src/system_stm32l4xx.c.o CMakeFiles/431test.elf.dir/Drivers/STM32L4xx_HAL_Driver/Src/stm32l4xx_hal.c.o CMakeFiles/431test.elf.dir/Drivers/STM32L4xx_HAL_Driver/Src/stm32l4xx_hal_cortex.c.o CMakeFiles/431test.elf.dir/Drivers/STM32L4xx_HAL_Driver/Src/stm32l4xx_hal_dma.c.o CMakeFiles/431test.elf.dir/Drivers/STM32L4xx_HAL_Driver/Src/stm32l4xx_hal_dma_ex.c.o CMakeFiles/431test.elf.dir/Drivers/STM32L4xx_HAL_Driver/Src/stm32l4xx_hal_flash.c.o CMakeFiles/431test.elf.dir/Drivers/STM32L4xx_HAL_Driver/Src/stm32l4xx_hal_flash_ex.c.o CMakeFiles/431test.elf.dir/Drivers/STM32L4xx_HAL_Driver/Src/stm32l4xx_hal_flash_ramfunc.c.o CMakeFiles/431test.elf.dir/Drivers/STM32L4xx_HAL_Driver/Src/stm32l4xx_hal_gpio.c.o CMakeFiles/431test.elf.dir/Drivers/STM32L4xx_HAL_Driver/Src/stm32l4xx_hal_i2c.c.o CMakeFiles/431test.elf.dir/Drivers/STM32L4xx_HAL_Driver/Src/stm32l4xx_hal_i2c_ex.c.o CMakeFiles/431test.elf.dir/Drivers/STM32L4xx_HAL_Driver/Src/stm32l4xx_hal_pwr.c.o CMakeFiles/431test.elf.dir/Drivers/STM32L4xx_HAL_Driver/Src/stm32l4xx_hal_pwr_ex.c.o CMakeFiles/431test.elf.dir/Drivers/STM32L4xx_HAL_Driver/Src/stm32l4xx_hal_rcc.c.o CMakeFiles/431test.elf.dir/Drivers/STM32L4xx_HAL_Driver/Src/stm32l4xx_hal_rcc_ex.c.o CMakeFiles/431test.elf.dir/Drivers/STM32L4xx_HAL_Driver/Src/stm32l4xx_hal_tim.c.o CMakeFiles/431test.elf.dir/Drivers/STM32L4xx_HAL_Driver/Src/stm32l4xx_hal_tim_ex.c.o -o ../bin/431test.elf

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
