不良缺陷；格式为-Defsym名称=值
说明：我已经创建了一个STM32项目，旨在获取独立于平台的构建和输出文件，例如.hex，.bin和.elf。为此，我在CMake Build System下创建了项目。已经进行了CMAKE配置设置和工具链设置。但是，在构建阶段结束时，我遇到了这个错误。
链接标志：在“ Compiler_flags.cmake”文件下。

Explanation: I've created an STM32 project and aim to get a platform-independent build and output file like .hex, .bin, and .elf. For this, I created the project under the CMake build system. CMake configuration settings and toolchain settings have been made. However, towards the end of the build phase, I encountered this error.
Linker flags: Under "compiler_flags.cmake" file.

错误的来源是汇编程序编译器工具链定义中。通过键入
Arm-None-eabi-gcc.exe而不是ARM-NONE-NONE-EABI-AS.EXE来解决该问题。The source of the error was in the assembler compiler toolchain definition. The problem was solved by typing
arm-none-eabi-gcc.exeinstead ofarm-none-eabi-as.exe.您的
ldflags有错误：-wl，-gc-sections-defsym ... __cxa_pure_virtual = 1应该是更改为-wl， - defsym，__ cxa_pure_virtual = 1Your
LDFLAGShave mistakes:-Wl, --gc-sections-defsym ... __cxa_pure_virtual=1should be changed to-Wl,--defsym,__cxa_pure_virtual=1
