我在构建内核时遇到问题。这是我在终端中输入的内容。
$ wget https://cdn.kernel.org/pub/linux/kernel/v5.x/linux-5.5.16.tar.xz
$ xz -d linux-5.5.16.tar.xz
$ tar xvf linux-5.5.16.tar
$ apt update
$ apt install build-essential libncurses5 libncurses5-dev bin86 kernel-package libssh-dev bison flex libelf-dev
$ cd linux-5.5.16/
$ cp /boot/config-5.15.0-30-generic ./.config
$ make menuconfig
$ make -j6
$ make modules并且发生了下面的错误代码。

我今天也遇到了这个错误。原因是最新的 gcc/g++ 有 bug。您应该将 gcc/g++ 版本降级到 9.4。见第二个答案[https://askubuntu.com/questions/26498/how-to-choose-the-default-gcc-and-g-version]
