Linux 5.12.9 compilation issues in swab.h, byteorder/little_endian.h

Hi! I'm trying to compile the Linux 5.12.9 kernel (for a KISS Linux installation); I was originally trying out the Zen kernel but tried switching to the vanilla kernel from kernel.org and experienced the same issue. This issue was that, after generating a config with `make defconfig` and reviewing `make menuconfig` (although I did not edit anything in the config at all), `make -j4` failed very soon with a compiler error. I'm a first-timer at compiling the kernel, so I have no idea what went wrong, but I'm wondering if there are some options I ought to have changed in the config pre-compilation that I didn't? The make output told me the following (a lot of times):

Code:
/usr/include/linux/swab.h:171:8: error: unknown type name '__always_inline
[/usr/include/linux/swab.h:184:30: error: expected '=', ',', ';', 'asm' or '__attribute__' before '__swab32p'
and
Code:
/usr/include/linux/byteorder/little_endian.h:44:8: error: unknown type name '__always_inline'
/usr/include/linux/byteorder/little_endian.h:60:31: error: expected '=', ',', ';', 'asm' or '__attribute__' before '__cpu_to_le16p'
The errors are pretty similar, there only seem to be two types of errors and only in two files. I did install libelf, I'm on a working KISS chroot; any advice as to what could be causing the errors would be super helpful. My thanks in advance — and apologies if this is a question better suited to one of the other subforums!

You may try to customize configuration file for Slackware huge kernel - Slackware is using vanilla kernel.

Hi, thanks for the quick reply!! If I’m understanding correctly, you suggest using the config file for Slack’s huge kernel for my KISS system? Do you know where I can download the config file (or the whole sources) for the huge kernel? I tried looking around on Slack Wiki and googling but couldn’t really find much… Or did I misunderstand?

Of course you can use kernel - I am suggesting to use config file for Slackware kernel. You can customize it for your needs - but first of to build. To resolve the problem of source of issue.

Hi, I tried using the config file at https://mirrors.slackware.com/slackw...ernels/huge.s/, but I got the same output from make. I'm going to include the full output here now, if it helps:

Actually, I think I figured it out. See https://k1sslinux.org/news/20210507a; fixing the include issue in the source code did the trick. Thanks anyways!
