Currently, building Bazel on OpenBSD fails. I have been working on porting it. The current status is that I can build a Bazel binary that appears to work.

Here's an issue to track related PRs. Feel free to assign it to me if you like.

Update WORKSPACE to use new version of bazelbuild/platforms repository.

The motivation for this change is to pick up commit bazelbuild/platforms@46993ef, for the OpenBSD port in #10250.

Closes #10251.

Add C++ toolchain configuration for OpenBSD.
644b7d4 
In my limited testing, these changes appear to work. When I built Bazel on OpenBSD incorporating these changes, the resulting `bazel` binary could build C++ libraries and binaries. Likewise on FreeBSD.

This change, split out of the larger PR #10274, is part of the OpenBSD port in #10250.

Closes #10436.

Add remaining changes for bootstrap build on OpenBSD.
d6145a0 
I have tested these changes via a bootstrap build on OpenBSD 6.6-current (amd64 architecture). The resulting `bazel` binary appeared to work in some simple testing involving `cc_library`, `cc_binary`, `java_library`, and `java_binary`.

Known issues/limitations:

- Building a `java_binary`'s deploy JAR fails because the `singlejar` tool fails to build. I intend to investigate soon.

- Running Bazel requires a `--host_javabase=@local_jdk//:jdk` flag.

- Sandboxing is unsupported.

This change, split out of the larger PR #10274, is part of the OpenBSD port in #10250. Most of the changes in that larger PR have already been committed via several smaller PRs (see the PRs linked from #10250). This PR collects the remaining changes.

Closes #10567.

On OpenBSD, search the PATH to find the Bazel executable.
dd41ff0 
Searching the `PATH` is the only feasible way to find the executable on OpenBSD when `argv[0]` is not an absolute path or a relative path. This change resolves a TODO.

This change moves a preexisting `Which` function for searching the `PATH` out of `blaze_util_linux.cc` and into `blaze_util_posix.cc`, so that the Linux code and the BSD code can share this function.

In my testing on OpenBSD 6.6-current, a bootstrap build of Bazel succeeds and the resulting `bazel` binary can find itself on the `PATH`. (One caveat: For the bootstrap build to succeed, I had to manually apply the unrelated change in #10639, since it's not merged yet.)

This change is part of the OpenBSD port in #10250.

@jmmv FYI.

Closes #10691.

Tweak Python semantics for Python 3 and OpenBSD.
15d80dc 
As discussed at #10432 (comment), Bazel is already switching to assume that the Python binary is called `python3`, not `python`.

This change is also useful for the OpenBSD port in #10250. (On OpenBSD, the python executable is called `python3`, and no `python` binary exists.)

Closes #10432.

For anyone following along:

  • Other relevant commits include ba6be8a and ebf6a46.

  • A bootstrap build of Bazel on OpenBSD now succeeds and yields a bazel binary that works. One caveat is that the bootstrap build requires python to be on the PATH; it can just be a symlink to /usr/local/bin/python3.

FYI, the build is now packaged as an OpenBSD port (although currently the port is not merged into OpenBSD's ports tree).
