Building Riak on SmartOS, the hard way

Build Machine

Here is some information on the build machine I'm using for reference:

1. Dataset

   $ dsadm list
   UUID                                 OS      PUBLISHED  URN
   467ca742-4873-11e1-80ea-37290b38d2eb smartos 2012-02-14 sdc:sdc:smartos64:1.5.3

2. Global Zone version

   [root@00-1b-21-a3-86-51 /tmp]# uname -a
   SunOS 00-1b-21-a3-86-51 5.11 joyent_20120223T221136Z i86pc i386 i86pc

3. Package Set (on SmartOS guest)

   $ cat /opt/local/etc/pkgin/repositories.conf
   http://pkgsrc.joyent.com/sdc6/2011Q3/gcc46-64/All

4. GCC version

   $ gcc --version
   gcc (GCC) 4.6.1

Requirements

$ pkgin -y install gmake gcc-compiler binutils scmgit pkg_alternatives autoconf sun-jdk6-6.0.26

NOTE You can remove the sun-jdk6-6.0.26 if you aren't building riak_ee

Building Erlang R14B04 from source

Get R14B04 Source with DTrace

Clone the OTP repo from Scott Fritchie's repo to get DTrace

$ git clone git://github.com/slfritchie/otp.git
$ cd otp
$ git checkout dtrace-r14b04

When I built it, the last commit was:

commit 6762a53e26db0dffbde542234fd3d18ebe337f58
Author: Scott Lystig Fritchie <slfritchie@snookles.com>
Date:   Sat Feb 11 22:44:11 2012 -0600

    Fix type error in dtrace:user_trace_i4s4()

Boostrap

Generate the configure script and configure

$ env ERL_TOP=`pwd` ./otp_build autoconf

Apply Patches

There are two patches that are needed to make things behave on SmartOS.

OMIT_OMIT_FP

The first one applies to Makefile.in files and makes adjustments to the OMIT_OMIT_FP flags:

Assuming you call this makefile.patch you can apply it like

$ patch -p0 < makefile.patch

inet_drv.c

Erlang's configure doesn't pick up on SmartOS being a Sun kernel in all the places it needs to, so this patch fixes inet_drv.c

Assuming you called the file inet_drv.patch you can just

$ patch -p0 < inet_drv.patch

Configure & Make

Finally we can start building.

Configure:

$ env ERL_TOP=`pwd` ./configure --enable-dtrace + EVERYTHING YOU NEED

This is what I did exactly:

$ ./configure --prefix=/usr/local/erlang-r14b04-dtrace-64 --enable-dtrace --enable-m64-build

Make:

$ make
$ sudo make install

I know, droppin' knowledge on that last one!

If you applied the patches correctly you should see something like this fly by on make:

* * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * *
* * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * *
* *                                                         * *
* * NOTE: Omit frame pointer optimization has been omitted  * *
* *                                                         * *
* * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * *
* * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * *

If not, you did something wrong!

Checking the install

This is what I have after I install using the above instructions:

$ erl
Erlang R14B04 (erts-5.8.5) [source] [64-bit] [smp:8:8] [rq:8] [async-threads:0] [hipe] [kernel-poll:false] [dtrace]

Make sure that "[dtrace]" is listed before moving on!

Building R15B01 from Source

Get the Source!

$ wget http://www.erlang.org/download/otp_src_R15B01.tar.gz

Configure / Make / Install

Unlike R14B04, this one works out of the box

$ ./configure --prefix=/usr/local/erlang-r15b01-dtrace-64 --with-dynamic-trace=dtrace --enable-m64-build
$ make
$ sudo make install

Confirm the basic install works

Erlang R15B01 (erts-5.9.1) [source] [64-bit] [smp:8:8] [async-threads:0] [hipe] [kernel-poll:false] [dtrace]

Eshell V5.9.1  (abort with ^G)
1> dyntrace:available().
true
2> 

Done.

Building Riak

Source / Devrel Build

This works out of box, just do the typical make commands.
