Any other potentially useful information about your toolchain?
This is related to the infamous circl dependency.
What did you do?
I have a go_binary that through a long list of dependencies ends up depending on circl. I do get circl from the BCR:
bazel_dep(
name = "circl",
version = "1.3.8",
)
My binary rule is defined as such:
go_binary(
name = "api",
embed = [":api_lib"],
gotags = ["purego"],
pure = "on",
)
I try to build it like:
bazel build //control-plane/api --platforms=@rules_go//go/toolchain:linux_arm64
My error:

What did you expect to see?
I expected this build to not need the C++ toolchain.
What did you see instead?
An error for C++ toolchain.
