This page contains notes on the setup of a Solaris buildbot worker for MIT krb5.

Our current Solaris build hardware is a Sun Fire V240 running Solaris 10 U10.

Solaris 10 includes a variety of free software tools in /usr/sfw, but not the full set of dependencies needed to checkout, build, and test the krb5 tree. We have chosen to use OpenCSW to add most of the dependencies, and local builds in /usr/local for the remaining few.

Set up a useful shell

A root login by default uses a very minimal shell (/bin/sh) with a very minimal path (/usr/sbin:/usr/bin). For any operations performed as root, we begin by starting a functional shell as follows:

   bash
   export PATH=/opt/csw/bin:/usr/sbin:/usr/bin:/usr/sfw/bin:/usr/ccs/bin
   export MANPATH=/opt/csw/share/man:/usr/share/man:/usr/sfw/share/man

For now, we are not modifying /etc/passwd or root's dotfiles to make this happen automatically.

Set up OpenCSW

Installing the pkgutil command (it will be placed in /opt/csw/bin) and update its catalog as follows:

   pkgadd -d http://get.opencsw.org/now
   pkgutil -U

"pkgutil -l" lists installed packages. "pkgutil -a string" looks up string in the catalog. "pkgutil -i packagename" installs a package; the -y flag can be used to skip prompts.

Install required OpenCSW packages

   pkgutil -y -i git
   pkgutil -y -i libssl_dev
   pkgutil -y -i autoconf
   pkgutil -y -i expect
   pkgutil -y -i bison
   pkgutil -y -i emacs
   pkgutil -y -i gdb

OpenSSL 0.9 is present in /usr/sfw/lib, but we need 1.0 or later for PKINIT so we install the OpenCSW version. The bison in /usr/sfw/bin is also too old for our x-deltat.y file. emacs and gdb are not needed to build krb5, but are handy to have around for manual testing and debugging work.

Local builds of remaining dependencies

dejagnu is not present in OpenCSW, so we need to build it ourselves:

   mkdir /usr/local /usr/local/src
   From https://ftp.gnu.org/gnu/dejagnu/ fetch the latest dejagnu; untar it in /usr/local/src
   cd /usr/local/src/dejagnu-version
   ./configure && gmake install

Create user accounts

By default, /home on Solaris is controlled by the automounter. To avoid needing to change the automounter configuration, we create user accounts with home directories in /export/home:

   useradd -d /export/home/ghudson -s /bin/bash -m ghudson

Creating an account allows the Kerberos principal of the same name in the ATHENA.MIT.EDU realm to log in on that account.

To set a reasonable path for development work, the user can edit .profile to add:

   PATH=/usr/local/bin:/opt/csw/bin:/usr/bin:/usr/sfw/bin:/usr/ccs/bin
   MANPATH=/usr/local/share/man:/opt/csw/share/man:/usr/share/man:/usr/sfw/share/man
   export PATH MANPATH

The following shell function, or a variant of it, may be useful for configuring a build with the correct paths. This variant is designed to work in a separate build directory placed next to the src directory within a checkout.

   k5configure() { ../src/configure --enable-maintainer-mode --prefix=$HOME/inst --with-ldap CFLAGS=-g CPPFLAGS="-I/opt/csw/include" LDFLAGS="-L/opt/csw/lib -R/opt/csw/lib" "$@"; }

To do

  • We should install the OpenCSW OpenLDAP package. (We have decided not to support the old Mozilla LDAP library any more.)
  • The system needs to be set up as a buildbot worker.
  • We should install the SunPro compiler and do automated builds with that compiler as well as gcc.
