Getting GNU Linear Programming Kit (GLPK) into the OpenSolaris /contrib repository

---

OpenSolaris is a very, very robust operating system and now that /contrib is open for putting
open source applications into its balliwick, I want to show how easy it is to get those highly
productive open source application into it.

How I started

• GLPK 4.38 (or the latest version)

  
  

• OpenSolaris 2008.11, shortly to be a later version

  
  

• SUNWbinutils

• Studio compilers (the version which can be downloaded from the repository)

  
  

http://www.gnu.org/software/glpk/glpk.html
is the link to GLPK. This is where I started to look at GLPK, pulling the source code from there.

I currently have 2 test development environments, the first contains the latest version of
OpenSolaris. The other is the same as the /contrib environment, which is 2008.11. I have 2008.11
because I know that when I push something to /contrib, it will need to be built in the environment,
which /contrib gets updated, I will recheck all my work and re-submit if necessary.

Building 32bit GLPK

---

# gzip -d glpk-4.38.tar.gz

# tar xvf glpk-4.38.tar

# ./configure –prefix=/usr/share/glpk CC=/opt/SunStudioExpress/bin/cc CFLAGS=-xO4 –with-gnu-ld –enable-shared

# gmake

# gmake install

A 32bit version of GLPK should be installed in /usr/share/glpk, this allowed me to test to
make sure my build of GLPK was good, there are a bunch of examples files to run with the source

---

Building 64bit GLPK

---

# ./configure –prefix=/usr/share/glpk64 CC=/opt/SunStudioExpress/bin/cc CFLAGS=”-xO4 -xtarget=opteron
-xarch=amd64″ –with-gnu-ld –enable-shared

# gmake

# gmake install

A 64bit version of GLPK should be installed in /usr/share/glpk64, this allowed me to test to
make sure my build of GLPK was good, there are a bunch of examples files to run with the source

---

All done with testing, GLPK looks good both 64bit and 32bit, now to get ready to put into the repository

---

Creating the spec file

---

This is the spec file that I have created for building on OpenSolaris.org for submission to /contrib.
the file is named, glpk.spec

#
# spec file for package: glpk
#
# This file and all modifications and additions to the pristine
# package are under the same license as the package itself.
#

%include Solaris.inc

%define glpk_dir /usr/share/%{name}

%description
The GLPK (GNU Linear Programming Kit) package is intended for solving

large-scale linear programming (LP), mixed integer programming (MIP),

and other related problems. It is a set of routines written in ANSI C
and organized in the form of a callable library.

Changed CFLAGS to compile 64bit on Studio 11

Submitting to /contrib

---

There are now two steps left to get GLPK into the repository, From the submission screen,
I needed to included the glpk.spec file, and also, I needed to include the copyright file
that is included with the source named, COPYING. I copied this file to one called glpk.copyright,
which is what I am looking for in the glpk.spec file via the variable SUNW_copyright.

With these two pieces in place, the submission is then in the hands of opensolaris.org to
validate. Once the validation is complete, then the source is built, and any errors, of
which I had a few initially, are logged, or if the build passes, a log is generated and
also the ability to download and check the IPS is created in /pending.

Once others have had a chance to check out GLPK, it will be voted on to move to /contrib.
