【问题描述】：
我正在尝试使用 CMake 创建和编译基于 ARM 的 STM32 项目。

当我尝试编译时，出现以下错误：
[ 82%] Building C object CMakeFiles/FixtureTACO_STM32F303xC.elf.dir/platforms/stm32f3/Hal/src/stm32f3xx_ll_utils.c.obj
[ 86%] Building ASM object CMakeFiles/FixtureTACO_STM32F303xC.elf.dir/platforms/stm32f3/Startup/startup_stm32f303xc.s.obj
cc: warning: ‘-mcpu=’ is deprecated; use ‘-mtune=’ or ‘-march=’ instead
cc: error: unrecognized command line option ‘-mthumb’; did you mean ‘-mtbm’?
cc: error: unrecognized command line option ‘-mfpu=fpv4-sp-d16’
cc: error: unrecognized command line option ‘-mfloat-abi=hard’
仅当源文件中存在程序集文件（在本例中为 startup.s）并且存在 FPU 和 FLOAR_ABI 标志时，才会出现该错误。可以看到，编译startup_stm32f303xc.s的时候会报错。
我怀疑我在错误的位置添加了这些标志，但我不知道在哪里添加它们才能使其正常工作。
稍后编辑：我已经在我的 ubuntu 系统上安装了 arm 7 编译器。我可以在不指定任何路径的情况下使用它，因为它已经存在于环境变量中。我可以毫无问题地为机器上的其他目标编译 ARM 代码（来自 Makefiles）。我的问题是cmake。
【问题讨论】：
-
我的猜测是您需要使用生成器表达式和 $
来仅将 C 选项添加到 C 编译器和 ASM 选项到 ASM 编译器。实际上，您正在为两种语言的编译器添加选项，这就是编译 ASM 文件时中断的原因。 -
@Fred 我认为这正是我的问题。你能告诉我更多细节吗？
