Missing input error with CGO dependency #1871
Comments

The file is a symlink in the repo. How is it represented in the repo directory? If it is missing, then we may be doing something wrong during the download. |

It's missing. If I look in my bazel cache where those files are downloaded, I only see a build file and a source file. The build file still references It seems plausible that the symlink isn't be resolved when its downloaded. Would that make this a potential cd /home/user/.cache/bazel/_bazel_user/34c6fa7f467484e23b6742c76862b361/external/gazelle~~go_deps~com_github_envoyproxy_envoy/contrib/golang/common/go/api_impl/

Probably a Gazelle bug. This is how we fetch Go modules: https://github.com/bazelbuild/bazel-gazelle/blob/master/cmd/fetch_repo/module.go This does check the dirhash of the resulting directory, so I am surprised that this verification passes with the file missing. |

@fmeum I gave that a try. Gazelle fails to build when I set a local path. mkdir /tmp/gaz
cd !$
git clone https://github.com/bazelbuild/bazel-gazelle.git .
git checkout tags/v0.38.0Then I pointed my project at my local copy of gazelle. local_path_override(
module_name = "gazelle",
path = "/tmp/gaz"
) It fails to build gazelle before I put debug prints in.

What did you do?
This is my code. The envoy modules all have CGO dependencies, and depend on a c++ header.
When I run gazelle, the buildfiles get generated, and seem to be correct. Inspecting the build file in the bazel cache, it is identical to the build file in the repository. But the header file doesn't get included.
This is the module it isn't resolving. The
