Bug 726736 – golang-base.eclass : how do I set a higher dev-lang/go version requirement in an ebuild?

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Alexander Kurakin 2020-06-02 07:09:50 UTC]

Good day!

I see we have `>=1.10` as Go compiler versions for Go packages:
https://gitweb.gentoo.org/repo/gentoo.git/tree/eclass/golang-base.eclass#n26

How do I increase (I mean: increase correctly) this constraint in the .ebuild which `inherit golang-build`?

You should be able to set DEPEND="... >=dev-lang/go-@version@" regardless of which eclasses the ebuild inherits.

Thanks! But, will this:

    GO_DEPEND=">=dev-lang/go-1.10"
    DEPEND="${GO_DEPEND}"

override my

DEPEND="... >=dev-lang/go-@version@",

won't it?

You should use BDEPEND in the ebuild for dev-lang/go instead of DEPEND
since go is only run during the build and isn't needed during runtime.

Also, keep in mind that if your package has go.mod and go.sum in the top
level directory, you should inherit go-module instead of the golang-*
eclasses.

Thanks,

William

Should I use it before or after `inherit`?

And, after all, won't eclass'es
    GO_DEPEND=">=dev-lang/go-1.10"
    DEPEND="${GO_DEPEND}"
override my BDEPEND's setting?

If won't - why?

Thanks.

Ping.

eclass is sourced before ebuild, so ebuild's *DEPEND settings overrides the eclass ones.

Thanks!

P.S. I'm not a Gentoo or Go master but IMHO GO_DEPEND could be a (legal and documented) parameter :)
