[Bug] Planck EZ linking error: “collect2: error: ld returned 1 exit status” #9309

Closed Lilalas closed 4 years ago

Lilalas commented 4 years ago

I’m trying to compile the default keymap of the Planck EZ from the QMK repo.

Describe the Bug

This is the output of the build command:

$ qmk compile -kb planck/ez -km default

When I tried to compile the first time, the output was a little longer (it successfully compiled a bunch of files beforehand), but the error message was the same.

System Information

I’ve setup my build environment using pip install. Package is up to date (version 0.0.35).

Additional Context

I also tried to compile a few other default keymaps, all of which worked fine. So the issue is most likely related to this particular keyboard/keymap.

fauxpark commented 4 years ago

Your repo is quite out of date; the current tag is 0.9.7. Run git pull and then make git-submodule.

Lilalas commented 4 years ago

@fauxpark That’s bad, thank you for pointing that out. As I mentioned above, I’ve setup my build environment using pip, not git. I will have to look into building QMK from git. Unfortunately, this is not documented on docs.qmk.fm though, is it?

fauxpark commented 4 years ago

You don't have to, just cd to your qmk_firmware directory and run those two commands.

Lilalas commented 4 years ago

You were right. After updating it compiles without problem!

So the issue came down to me not understanding how to keep my installation up to date. Let me mention again that I think this is poorly (not at all) explained in the documentation. I will create a separate issue over there.

It's under the "Git Best Practices" section: https://docs.qmk.fm/#/newbs_git_using_your_master_branch

I'm getting the same (or at least a similar) error. I'm using QMK 0.10.50.

I did pull in the newest changes and did run make git-submodules. I'm building on Ubuntu 20.10 for an 'Ergodox Infinity'. All my system packages are up-to-date.

Any ideas?
