Not able to use dep to isolate vulkan dependency

[delaneyj]

Have a working example using go get, go run main.go works fine.

Use dep init to pull the same dependencies to the vendor folder.

  Using master as constraint for direct dep github.com/vulkan-go/vulkan
  Locking in master (f7f4611) for direct dep github.com/vulkan-go/vulkan
  Using ^0.8.0 as constraint for direct dep github.com/pkg/errors
  Locking in v0.8.0 (645ef00) for direct dep github.com/pkg/errors
  Using v3.3 as constraint for direct dep github.com/vulkan-go/glfw
  Locking in v3.3 (72ceac6) for direct dep github.com/vulkan-go/glfw

It appears there is bad path resolution happening.

Hi, it seems that dep omits some sources from the vendored dir, judging by the log lines.

Could you please verify that in this case:

vendor\github.com\vulkan-go\vulkan\cgo_helpers.go:10:27: fatal error: vulkan/vulkan.h: No such file or directory
compilation terminated.

You actually have vendor\github.com\vulkan-go\vulkan\vulkan\vulkan.h in place?

Also, could be a path issue. At this point I'm not sure on which stage of the pipeline the problem is. But in both cases packages have an internal directory with C-only sources, so dep could omit them. I don't have the env to test it by myself.

It looks like an issue
golang/dep#1223

that is surpassed by
golang/dep#944

Sorry, log weekend.

You actually have vendor\github.com\vulkan-go\vulkan\vulkan\vulkan.h in place?

No, but it is in C:\tools\mingw64\x86_64-w64-mingw32\include\GLFW and gets picked up when building with a copy at $GOPATH/src/github.com/vulkan-go/vulkan instead of in vendor

@delaneyj see the prune case. Godep removes C sources, it removed vulkan headers from your vendor/

Sorry forgot to close here, yeah not your fault just good for others to know. Curious how vgo would handle this.
