HI there
The master branch should have enough build fixes for GCC-8.
These patches were merged recently after 4.14 release and should not be backported to stable releases due to LKML policy.
Please try it.
Thanks.

master is 4.18-rc .
And There is not have ANY tag .
How to get a release version ? eg 4.17.5 .
Read commits ?

PS: 4.14.x is LTS version.

Just ugly workaround to build 4.9 branch with LLVM toolchain http://lists.llvm.org/pipermail/llvm-dev/2018-July/124620.html

@heiher It would be better if we can mark a tag for every stable release (not only LTS).

@jiangtao9999 I'm going to backport build fixes for GCC-8, please wait a moment.
Thanks.

@FlyGoat
If you can set tags with 4.17+ , fix gcc is not necessary.

Even more issue here...

It seemed like define of KERNEL_ENTRY is empty.

Hi jiangtao：
我遇到一个depmod的问题在4.14.74上，你build这块有这种情况么。方便的化发个你的src.rpm的链接。

什么 depmod 问题？ 我编译都很正常。 src.rpm 我不发了，就是瞎改了几个地方，强行改用我另外做的一个 config 文件去编译。没有动后面的一些和 mod 相关的内容。

嗯，是默认的config 的问题，PATA_PCMCIA 这个选项关了就没有这个问题了。但是万一需要PATA_PCMCIA控制的相关kernel的feature的话就需要细看了为什么会这样。@chenhuacai

那估计是内核里面依赖关系写的有问题。导致编译结果出来，丢失了部分必须的支撑驱动吧？
我印象里 kernel 好像自带了一个检测的功能，编译后可以计算差了什么。
