Bug 536960 – dev-lang/go-9999 should depend on >=dev-lang/go-1.4 / go 1.4 binaries for bootstrapping

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Bohdan Trach 2015-01-18 11:16:23 UTC]

Live ebuild of go (for versions >= 1.5) now requires go-1.4 [1] as per project's bootstrapping plans [2]. On i386 and amd64 prebuilt packages from http://golang.org/dl/ can be used, and it's likely that full bootstrapping is required on other arches.

Reproducible: Always

Created attachment 394246 [details, diff]
fixes to go-9999 ebuild hardcoded to amd64

With this changes to ebuild I managed to compile latest go version, so the fix with prebuilt packages should be rather easy. It is hardcoded to amd64, and only shows the idea.

Wouldn't it be fun if it could use an installed version as well?

[Comment 3 William Hubbs 2015-01-20 04:32:18 UTC]

The approach I took was to create a new package, dev-lang/go-bootstrap,
which is a separate installation of go-1.4.1 which installs in
/usr/lib/go1.4. This path then is used as GOROOT_BOOTSTRAP in the live
ebuild which has a build-time dependency onn
>=dev-lang/go-bootstrap-1.4.1.

[Comment 4 Jeroen Roovers (RETIRED) 2015-01-23 14:42:04 UTC]

But that means you always pull in dev-lang/go-bootstrap on rebuilding dev-lang/go, even when a perfectly good alternative (dev-lang/go) is in place?
