Hello, I have an issue with golangci-lint in Github Actions. I tried using the official golangci/golangci-lint-action@v1, then tried manually installing the linter and then I even tried running it multiple times just to see if it's not a random fail. Neither run was succesful and I'm always getting some errors regarding could not import C (cgo preprocessing failed). Strange thing is that if I run the linter locally, everything works as expected (I even tried multiple versions...), see screenshot:

Here are the failed builds (with detailed info):

using the Github Action: https://github.com/grongor/go-snmp-proxy/runs/734271995
direct install, single try: https://github.com/grongor/go-snmp-proxy/runs/734293704
direct install, multiple tries: https://github.com/grongor/go-snmp-proxy/runs/734297231

I also tried removing the golangci-lint locally, and running it in the same way as I do on CI ... and it works:

The reason for this working on your local machine and not in the workflow is because you've also installed some dependent C libraries on your machine (net-snmp/net-snmp-config.h and net-snmp/mib_api.h). I get the same error on a fresh machine with any version of golangic-lint. For the linting to work the code needs to be able to compile. This is not possible without the headers as seen with go test.

$ go test ./...
# github.com/grongor/go-snmp-proxy/snmpproxy

So to sum it up, you need to add your header files in /usr/local/include in the action before running golangci-lint.

OMG! I should've figured that out...This was my first time playing with cgo so I wasn't sure about many things. I'm so sorry for wasting your time like that and thank you for taking the time to write such a detailed answer.

Just for reference, the solution was really simple:

-   name: Install dependencies
    run: sudo apt update && sudo apt install libsnmp-dev

grongor · 2020-06-05T07:31:30Z

By the way, do you @bombsimon think that it would be possible to improve the error message somehow, ideally telling the user that it wasn't able to include the required headers? That would immediately put me on the right path...at first I though "ok, golangci-lint doesn't work with C imports at all"...if so, I would take look it :)

bombsimon · 2020-06-05T07:40:51Z

I don't think golangci-lint should say what kind of compilation error occurs, although requests to make it more clear that it's a compilation error and that the code won't lint since it wont compile exist. Something in line with what you're asking about is discussed in #1043 and also related in #1172.

charleskorn · 2022-04-03T00:54:16Z

Do you have any suggestions on how to debug this issue? I'm seeing it for my project where everything works fine locally, and building on CI works without issue, but golangci-lint fails on CI. Is there some way to get more detailed information on what has gone wrong?

still not clear what to do in order to resolve this
