[Bazel] fatal error: Platform.h: No such file or directory

[Chounoki]

Hi, I am building a Golang project with Bazel which imports go-tpm-tools as a dependency.

During the building, I got the error:

ERROR:

compilation terminated.

Since I am importing go-tpm-tools as a remote repo directly from Github, I can not copy a "Platform.h" file into go-tpm-tools project root directory, is there any solution I can try?

Thank you.

Alternatively, could you add the support of Bazel natively as a Bazel module for go-tpm-tools?

Hi, we never tried using bazel to build this repo yet.
Maybe try to clone the repo and build it locally?

I don't think we currently have the bandwidth to support bazel. But this is something we'll do later, especially for its reproducibility

That's the problem. If we make a local clone, add the Bazel build rules and put the clone into our Github repository, it will be permanently stuck to that specific version of go-tpm-tools unless someone manually updates it.

PS: I don't think it would require too much effect adding the Bazel build module support for google/go-tpm-tools since Bazel is just the open source version of Google's internal build tool.

I've created a pull request to add Bazel support: #616
