Go 1.5 on Solaris 11 x86

Last updated at Posted at 2015-12-18

Go!!
クマなのかネズミなのか分からないけれど、
手元の Solaris 環境でもコンパイルできたら良いのに。
・・ならやってみましょう。ものは試し。

Go 1.5 Bootstrap Plan によると、
go1.5 では C ソースを撤廃し go1.4 を利用した toolchain ビルドで生成できるとのことです。

さっそく official からソースを入手。

今回試したコンパイル環境は以下の通り。

  • SunOS 5.11 11.2 i86pc i386 i86pc
  • gcc version 4.5.2 (GCC)
  • GNU Make 3.82 Built for i386-pc-solaris2.11

Compile Go 1.4

$ tar xzf go1.4.3.src.tar.gz 
$ mv go go1.4.3
$ cd gol1.4.3/src
$ ./make.bash
(Snip)
---
Installed Go for solaris/amd64 in /opt/local/src/golang/go1.4.3
Installed commands in /opt/local/src/golang/go1.4.3/bin

Compile Go 1.5

$ export GOROOT_BOOTSTRAP=/opt/local/src/golang/go1.4.3
$ tar xzf go1.5.2.src.tar.gz
$ mv go go1.5.2
$ cd go1.5.2/src
$ ./make.bash
(snip)
---
Installed Go for solaris/amd64 in /opt/local/src/golang/go1.5.2
Installed commands in /opt/local/src/golang/go1.5.2/bin

あっさり、できてしまった。

Cross-compile environment

GOROOT_BOOTSTRAP は /opt/local/src/golang/go1.4.3 のまま。

ちなみに勇んで GOROOT_BOOTSTRAP を 1.5.2 のパスに切り替えると、
compile コマンドが見つからない、というエラーが出る。

$ env  | grep GOROOT
GOROOT_BOOTSTRAP=/opt/local/src/golang/go1.4.3
$ GOOS=linux GOARCH=amd64 ./make.bash 
(snip)
---
Installed Go for linux/amd64 in /opt/local/src/golang/go1.5.2
Installed commands in /opt/local/src/golang/go1.5.2/bin

できあがり。
