我有一个在 dkms 中注册的内核模块。最近一次升级将我的内核升级到 4.15.0-50 后,我开始收到来自 dkms 的以下错误。显然,内核 4.15.0-50 是用 gcc 版本 7.3.0 编译的,但升级的一部分涉及安装新版本的 gcc (7.4.0),这导致 dkms 失败。我的系统上不再提供 gcc 7.3。除了 7.4 之外,我如何安装 gcc 7.3,甚至将 7.4 降级到 7.3?

答案1
您无需安装多个版本的 gcc,可以将以下选项传递给 nvidia 安装程序:
--no-cc-version-check
适用于 Ubuntu 18.04.2、内核 4.18.0-20 和 nvidia 430.14。

答案3
在我的情况下,我可以选择无论如何都要编译,但安装失败了。我想我需要 gcc 7.3。我想知道 gcc 7.4 编译器是否有一个选项可以在 v. 7.3 上进行编译。
其他人说你需要有头文件,但是当我尝试添加它们时我收到了一条错误消息。
目前,我更愿意使用 gcc 7.3 编译器,因为我不太需要 gcc 7.4 编译器。我不确定如何解决这个问题。
