Cannot build on Illumos

[francescocarzaniga]

Trying to build on Illumos results in the following error:

root@build_env:/tmp# go get -u github.com/gofrs/flock

This seems to present a solution.

@francescocarzaniga I'm personally not very familiar with Illumos, so I presume it doesn't have the same system call capabilities as other systems so the symbols are missing when attempting to build.

Considering that you have a Illumos system, would you have the spare cycles to contribute support for that OS? Alternatively, do you have any personal recommendations for where I could get access to one without having to get some local VM running?

[francescocarzaniga]

@theckman I have a personal server with OmniOS where I could spin up a zone for this, it's not particularly powerful but it should do. AFAIK there are no (affordable, Joyent is quite expensive) cloud solutions.

Hi
I solved the compilation error by using the environment variable:
export GOOS=illumos

so flock is compiling fine.
I hope it helps someone.
