Description Michele Testa 2020-12-08 22:30:35 UTC
After enabled wireguard module in kernel 5.4.80-r1 (CONFIG_WIREGUARD=m), compiling fails with errors:

gcc: error: ":: No such file or directory
gcc: error: ": No such file or directory
gcc: error: fmt: No such file or directory
make[3]: *** [scripts/Makefile.build:266: drivers/net/wireguard/main.o] Error 1
make[2]: *** [scripts/Makefile.build:500: drivers/net/wireguard] Error 2
make[1]: *** [scripts/Makefile.build:500: drivers/net] Error 2
make: *** [Makefile:1729: drivers] Error 2

Reproducible: Always

Steps to Reproduce:
1. Enable wireguard as kernel module: CONFIG_WIREGUARD=m in .config
2. root@/usr/src/linux # make drivers/net/wireguard/wireguard.o 
3. gcc stops with error
Actual Results:  
Compiling the kernel fails

Expected Results:  
Compiling the kernel succeed with wireguard built as module

Patch to fix wireguard Makefile

Just remove the line:

    ccflags-y += -D'pr_fmt(fmt)=KBUILD_MODNAME ": " fmt'

and gcc will run smoothly
Comment 2 Mike Pagano gentoo-dev 2020-12-08 23:09:42 UTC
No problem here on amd64. Can you attach your.config ?
Comment 3 Michele Testa 2020-12-08 23:34:44 UTC

.config kernel 5.4.80-gentoo-r1

My .config after wireguard module was built with the submitted patch.
Comment 4 Mike Pagano gentoo-dev 2020-12-09 19:09:28 UTC
I'm having trouble replicating.

I built 5.4.82 with your .config using both gcc 9.3.0-r1 and 10.2.0-r3 without issue.

Can I see your emerge --info, please ?

emerge --info

Thanx a lot Mr. Pagano, for all your awesome work on the kernel :)
Comment 6 Mike Pagano gentoo-dev 2020-12-13 16:41:27 UTC
Do you have coreutils installed?

gcc: error: fmt: No such file or directory

/usr/bin/fmt is part of that package.
Comment 7 Michele Testa 2020-12-14 02:51:15 UTC
Yes, I've installed the last version of coreutils:

Compiling with verbose=1, I have the error on the command:

IMHO, in:

for some reason whitespaces in single quotes are tokenized, so gcc search for '":', '"' and 'fmt' as files, giving the error:

> gcc: error: "    : No such file or directory
> gcc: error: fmt  : No such file or directory
Comment 8 Alice Ferrazzi Gentoo Infrastructure gentoo-dev 2021-03-29 08:09:54 UTC
can you test this with 5.4.108?
