大家好，我使用的是RTL8852BE型号的WiFi网卡，之前在Ubuntu 22.04系统上遇到网卡无法识别的问题时，通过相关方案解决了驱动兼容问题，过去几个月一直正常使用。但最近系统完成内核更新（当前内核版本：5.19.0-32-generic）后，重新编译驱动包时出现了编译失败的情况，具体的编译命令和报错信息如下：

elli@elli-ThinkPad-E15-Gen-4:~/rtl8852be$ make

#rm -f .symvers.8852be

make ARCH=x86_64 CROSS_COMPILE= -C /lib/modules/5.19.0-32-generic/build M=/home/elli/rtl8852be  modules

make[1]: Verzeichnis „/usr/src/linux-headers-5.19.0-32-generic“ wird betreten

warning: the compiler differs from the one used to build the kernel
