It's incredible to run buildall.sh on a recent go repo and see all the cross-compilers get built with no fuss or hassle. There are at least 30 different target platforms I can get to from my ubuntu box with a single command line.

I'm not aware of anything that even comes close to tooling out cross compilation so easily.

It's called NetBSD.

build.sh cross compiles one codebase for 57(+)[0] architectures. Even for a "native" build, the tooling is the same abstraction that builds for a completely foreign target, so it's continuously well-exercised.

I do nightly binaries for Prometheus in all the possible archs, while things should compile perfectly there can be small things that prevent things from cross-compiling.

darwin/arm, darwin/arm64, plan9/386, plan9/amd64 and solaris/amd64 don't compile for any of the 11 binaries (e.g. plan9 doesn't work due to logrus not having support for it).

This leaves me with the list at http://www.robustperception.io/prometheus-nightly-binaries/ That's still 20 architectures I can compile almost everything to automatically with an ansible+jenkins setup.

What is the problem with solaris/amd64?

../../Sirupsen/logrus/text_formatter.go:28: undefined: IsTerminal

The logrus library we use for logging doesn't support Solaris.

Looks like it does now:

Good to know, thanks. We vendor our dependencies so it'll be next release before this will work out of the box.
