Kernel 在64位Ubuntu 16.04上使用make kpkg编译32位内核失败

我试图使用make-kpkg为atom机器编译一个32位内核 64位ubuntu服务器计算机，但它失败并收到以下错误消息：

我曾经在我的32位虚拟机上成功地编译了32位内核。 但是在虚拟机上编译的时间是昂贵的。所以我决定编译 它在64位机器上运行。我将make kpkg参数设置为：

sudo make-kpkg --initrd kernel_image -j10 --arch i386 --cross-compile ""

但是它仍然收到了上面的错误消息，并且“i686 linux gnu gcc”无法被删除

容易被发现

对于交叉编译，您需要设置一个工具链

i686 linux gnu gcc

是此工具链的一部分。如何设置工具链？apt get install？是的，您可以通过

apt install

安装工具链。您可能很容易找到包含所需文件的软件包：。您知道要安装哪些项目吗？我的操作系统是ubuntu 16.04 LTSi不得不将我的linux服务器从16.04 LTS升级到18.04 LTS，以安装32位编译器工具链@Tsyvarev
