Failure when trying to cross compile for solaris

Host operating system: output of uname -a

I've tried this on both a Linux and a MacOS system.

Linux y0319t11346 3.10.0-514.16.1.el7.x86_64 #1 SMP Fri Mar 10 13:12:32 EST 2017 x86_64 x86_64 x86_64 GNU/Linux

node_exporter version: output of node_exporter -version

node_exporter, version 0.14.0 (branch: master, revision: 047003b)

Are you running node_exporter in Docker?

No

What did you do that produced an error?

<user>@<host>:~$ go get github.com/prometheus/node_exporter
<user>@<host>:~$ cd $GOPATH/src/github.com/prometheus/node_exporter
<user>@<host>:~/go/src/github.com/prometheus/node_exporter$ GOOS=solaris GOARCH=amd64 go build node_exporter.go

What did you expect to see?

A successfully created binary.

What did you see instead?

github.com/prometheus/node_exporter/collector

collector/loadavg.go:45: undefined: getLoad
collector/meminfo.go:44: c.getMemInfo undefined (type *meminfoCollector has no field or method getMemInfo)

I get the same thing. @kpettijohn, is there a trick to getting this cross-build to work?

[robinbowes]

I'm seeing the same thing on SmartOS. See prometheus/promu#52

There are two issues here, the meminfo collector isn't supported on solaris and shouldn't be built. I submitted a patch for that in #620.

More importantly though, node_exporter is a low-level program relying on C libraries. Cross-compilation with C code involved is not as simple as saying GOOS=solaris go build, you need to make sure that your c compiler has all the headers available for the target system. You'll find many posts and tutorials how to set up the correct environment to cross-compile programs using C code.

This is still happening on v0.16.0 and 0.17.0-rc.
