RT-Thread版本5.1.0,当使用keil5编译bsp\stm32\stm32f103-fire-arbitrary的时候,出现Undefined symbol rt_condvar_init (referred from pipe.o),发现在Kernel文件夹中没有包含condvar.c文件. ![图片](https://github.com/RT-Thread/rt-thread/assets/46878455/0e0b9997-1f99-4f5f-b126-cbe2025fb9bb) 将./components/drivers/ipc/condvar.c加入到工程中即可 ![图片](https://github.com/RT-Thread/rt-thread/assets/46878455/c5451271-2f35-4e03-8c5c-b6bbaa5cd099)
