It's possible that the issue is related to the missing glfw library from your system. Can you check if glfw is installed on your system? If you can confirm that glfw is installed on your machine, then please check also this issue https://github.com/esimov/diagram/issues/7, though I think the two issues are not strictly related to each other.

Also it might be possible that the issue is related to wrong vendoring. Try to use the -mod vendor directive. This command will instruct go mod to use the main module's top-level vendor directory to satisfy dependencies. Check this thread: https://github.com/golang/go/wiki/Modules#how-do-i-use-vendoring-with-modules-is-vendoring-going-away.

If still not working i'll look into the issue more deeply.

Also you can try to get the module with this command:

GOFLAGS='' go get github.com/esimov/diagram or

GO111MODULE=off go get github.com/esimov/diagram

Can you check if glfw is installed on your system?

It is installed

Try to use the -mod vendor directive.

It seems that go get is not accepting this directive:

$ go get -mod=vendor github.com/esimov/diagram
build flag -mod=vendor only valid when using modules

[esimov]

Try this one: GO111MODULE=off go get github.com/esimov/diagram. The -mod vendor directive is used only on builds.

[michal-halenka-datasentics]

I've tried. Nothing changed on the output.

[esimov]

Not even with GOFLAGS='' go get github.com/esimov/diagram? I'm afraid that go mod is fetching a different version of glfw then then one used in this library. That's the reason why you are getting the above error. Can you try with the above command?

[michal-halenka-datasentics]

Not even. The error is still the same.
