golangci-lint version 1.42.0 says typecheck error on Ubuntu 21.04 & Go 1.17 env

[xxpxxxxp]

Welcome

• Yes, I'm using a binary release within 2 latest major releases. Only such installations are supported.
• Yes, I've searched similar issues on GitHub and didn't find any.
• Yes, I've included all information below (version, config, etc).
• Yes, I've tried with the standalone linter if available. (https://golangci-lint.run/usage/linters/)

Description of the problem

golangci-lint version 1.42.0 says typecheck error on Ubuntu 21.04 & Go 1.17 env
In the meantime, it works well on Windows & macOS.
A toy project is attached: https://github.com/khadmitriy/project
CMD to repro the issue:
golangci-lint run --disable-all -E staticcheck ./...
This CMD works well on Windows & macOS with Go 1.17, but says typecheck error on Ubuntu 21.04

Hello,

typecheck is not a linter but a way to catch compilation errors in your code.

[xxpxxxxp]

Hi @ldez , I'm aware of that, what I'm saying is that the exact same cmd works on Windows & macOS but fails on Ubuntu. go build works on Ubuntu too.

[choleraehyq]

I also meet this problem. Under Go 1.17, go build success, but golangci-lint installed by curl -sSfL https://raw.githubusercontent.com/golangci/golangci-lint/master/install.sh | sh -s -- -b $(go env GOPATH)/bin v1.42.0 says typecheck error. Then I build and install golangci-lint locally under Go1.17 using go get github.com/golangci/golangci-lint/cmd/golangci-lint@v1.42.0, it doesn't say typecheck error again.

[choleraehyq]

I suspect precompiled binary is not compiled by Go 1.17.

[xxpxxxxp]

Thanks for the clue! I'll try it out see if it would resolve the issue.

[cniackz]

Thank you guys, this is working for me in Ubuntu Containers, thanks!!!!

[xxpxxxxp]

Thanks a lot @choleraehyq ! Compile from source solved the problem. Me too suspect the precompiled binary is not compiled by Go 1.17 and having compatibility issue on Linux. @ldez Any chance to release a new version to fix this?

[ldez]

The release v1.42.1 is available (build with go1.17)

[xxpxxxxp]

Thanks!

[choleraehyq]

@ldez should we also update documents here https://golangci-lint.run/usage/install/ ?

[ldez]

nope, because this page already contains the right information.

[fsyyft]

I have the same problem, is it because generics are not supported? Is there a way to filter out the checks on generics while preserving other functionality?

package main

import (
    "fmt"
)

type Addable interface {
	type int, int8, int16, int32, int64,
		uint, uint8, uint16, uint32, uint64, uintptr,
		float32, float64, complex64, complex128,
		string
}

func add[T Addable](a, b T) T {
    return a + b
}

func main() {
    fmt.Println(add(1,2))
}

main.go:8:2: expected '}', found 'type' (typecheck)
	type int, int8, int16, int32, int64,
	^
main.go:15:5: expected declaration, found 'return' (typecheck)
    return a + b
    ^

[ldez]

go1.17 doesn't support generics.

[go-goll]

please export CGO_ENABLED=0

Thank you guys, this discussion is still useful today for Ubuntu Containers, Wed Aug 10 2022...

I compiled the version locally, then all works as expected and no typecheck error is shown finally:

git clone https://github.com/golangci/golangci-lint.git
cd golangci-lint
make build
chmod +x golangci-lint
mv golangci-lint /usr/bin/golangci-lint
GO111MODULE=on /usr/bin/golangci-lint cache clean
GO111MODULE=on /usr/bin/golangci-lint run --timeout=5m --config ./.golangci.yml

Hi, I have this issue when running as a github action, have tried to use the supplied github-action, install with go install and git clone and make build.

My error was related to that a dependency to a private module didn't get downloaded correctly.
Really weird to get a typecheck-lint-error on this though.

[shellhazard]

Thanks for this reply - turned out I was experiencing the same weird behavior locally. The file containing the type I was using in the switch had a broken dependency, which was causing typecheck: previous case to be thrown. Running go mod tidy retrieved one dependency and fixed the problem. In my case no big deal as it would've resolved itself at build time but good to know what was causing it.
