[SOLVED] Cannot build any Go file: unexpected NUL in input in std libs

chelas · 2024-05-21 08:45:03

Currently on version 1.22.3. Issue persists even after reinstalling go. Right now I'm leaning towards the issue being a corrupted package, although I'm having trouble finding any actionable logs in that direction. Possibly be related to an unexpected power-off during an upgrade some months ago, but I believe I've taken care of everything that had to be done there and this is the only package acting out of the ordinary. I've searched the internet for solutions, but the only similar problems were caused by incorrect file encodings. Occurs even when trying to build the following code:

package main

import "fmt"

func main() {
	fmt.Println("Hello World")
}

The following errors come up:

main.go:3:8: read /usr/lib/go/src/fmt/doc.go: unexpected NUL in input
package command-line-arguments: read /usr/lib/go/src/runtime/abi_test.go: unexpected NUL in input

The same errors popup when trying to run anything more complex, just with more "unexpected NUL" in different std libs. I have checked the files mentioned and nothing appears to be out of the ordinary either

Can be reproduced quickly by running the following commands

mkdir hello && cd hello || exit
go mod init example/hello
cat > main.go << EOF
package main

import "fmt"

func main() {
	fmt.Println("Hello World")
}
EOF

# or alternatively running "go run ."
go build main.go

Here's the output of "go env". Should be unchanged from the default configuration (and is identical to the output of another working machine I have)

Here is the output of

pacman -Qkk | grep -v '0 missed files' | grep -v '0 altered files'

. Although I'm guessing that I'd be noticing more serious problems if anything were wrong with these packages...

Checking for broken symlinks with

find / -xtype l -print

doesn't yield anything relevant either. Some results pop up but they're all related to docker or flatpak (which I am not running Go under)

Apologies for the sparse information, but I'm at a complete loss on what the relevant logs would be

Package is fine, non-utf8 locale?

locale -a

Also did a quick hexdump of all involved files to sanity check for a NUL character.
Interestingly it compiles and runs fine when using the gccgo compiler as provided by the gcc-go package

Have you tried to

go clean -cache
go clean -testcache
go clean -fuzzcache
go clean -modecache

drop the caches?

chelas · 2024-05-22 16:23:31

Ouch, could've sworn that I did but when I checked I missed the "-cache" flag.
That did it! Thank you very much for your help
