如何清除链接器错误？ windows上交叉编译stm32

如何解决如何清除链接器错误？ windows上交叉编译stm32

我正在尝试交叉编译一个简单的 c/cpp 文件，目标是 stm32f030F4P，我成功地设置了 CMake 文件，并且 cmake 成功地为 ninja 构建了 build.ninja 文件。当我执行 ninja 时出现以下错误

PS C:\Users\varun\Desktop\Projects\stm32f030f4p\Firmware\Blinky\build> ninja.exe [1/1] 链接 CXX 可执行文件 .elf 失败：.elf cmd.exe /C "cd . && C:\DEV-TO~1\TOOLCH~1\GCC-AR~1\102020~1\bin\AR10B2~1.EXE -march=armv6-m -mcpu=cortex-m0 -mthumb -DSTM32F030x4 -Og -ggdb -Wall -Wextra -ffunction-sections -fdata-sections -ffreestanding -fno-builtin --specs=nano.specs -fno-rtti - fno-exceptions -Wno-volatile -std=c++1z -g CMakeFiles/.elf.dir/src/main.cpp.obj -o .elf && cd 。” c:/dev-to~1/toolch~1/gcc-ar~1/102020~1/bin/../lib/gcc/arm-none-eabi/10.2.1/../../.. /../arm-none-eabi/bin/ld.exe： c:/dev-to~1/toolch~1/gcc-ar~1/102020~1/bin/../lib/gcc/arm-none-eabi/10.2.1/../../.. /../arm-none-eabi/lib/thumb/v6-m/nofp\libg_nano.a(lib_a-exit.o): 在函数 exit': exit.c:(.text.exit+0x1e): undefined reference to _exit' collect2.exe 中：错误：ld 返回 1 退出状态忍者：构建停止：子命令失败。附注

请找到我的 CMakeLists.txt。

请找到我的 arm-none-eabi.cmake（原谅复制粘贴工具链的名称，不知道取什么名字）

我的链接脚本是从 STM32CubeIDE 复制粘贴的

最后c文件很简单

unsigned int counter;
int main(void)
{
    for(;;)
    {
        counter++;
    }
}
