Building from source.

  • If you want to run go1.3 or 1.4 on OpenBSD 5.6, see http://golang.org/issue/9102

Kernel version	Min. version	Max. version
5.8	go1.4.1	go1.6
5.7	go1.4.1	go1.6
5.6	go1.4.1	go1.6

• ulimits (/etc/login.conf)

Edit /etc/login.conf so that the staff class has the proper settings. The following is a working example of the staff class:

staff:\
       :datasize-cur=infinity:\
       :datasize-max=infinity:\
       :datasize=infinity:\
       :openfiles-cur=4096:\
       :maxproc-max=512:\
       :maxproc-cur=512:\
       :ignorenologin:\
       :requirehome@:\
       :tc=default:

If the database file /etc/login.conf.db exists, you need to rebuild it with:

# cap_mkdb /etc/login.conf

Ensure that the user you intend to build Go with is in the staff login class:

# usermod -L staff your_username_here
