As I was heading out for lunch today, I was thinking about my good old project Latrunculi. I wrote earlier that I was going to put it on hold until I finish Ocean. As Ocean is coming along (at the moment I am rewriting a great deal of the macro expander; the code is coming along cleaner and more elegant than before, but not as quickly as I should long), this could be a while and no wonder. While compilers are not magic, they are not done overnight, either. This leaves Latrunculi hanging. I don't like to leave projects hanging even though I routinely do it. So I decided to do a quick code audit and see how quickly I could push a first release out the door. I went to do a quick rebuild of the source and then remembered: since switching (for how long, we'll see) to Ubuntu, I hadn't installed Chicken Scheme. It is included in the repositories but, like Gentoo, the package was not up to date. The solution was obvious: do what any red-blooded OSS user would do: download the source.
The compilation went down without a hitch and as gobbledy-gook scrolled across my screen, I googled the creation of Debian packages. Why? Well, the whole point of a package manager is to manage your packages. As I quickly learned as a Slackware user (my fault, not Slackware's) if you do not do this properly, things can quickly become unmanageable, by man or machine. Towards the build's end, I came across an article on the use of checkinstall (http://www.debian-administration.org/articles/147),
a semiautomated method of generating Debian packages. The basics of Debian packages are easy to understand: a couple of control files and tars containing the actual files for the install--that doesn't mean that I felt like doing it by hand. Like all programmers, I am fundamentally lazy when it comes to computers. There are bigger, better things to do than haggle with control files. So I decided to give checkinstall a spin. The usage is trivially simple: after building, issue this command as root:
# checkinstall -D installcmd
Where the -D flag instructs checkinstall to make a Debian package (instead of an RPM or tgz) and installcmd is the command to run the install (make install, in most cases). I went ahead and generated the Chicken 2.6 package attached to this blog post. By default, checkinstall automatically installs the package after building it. Sure enough, it worked. The one caveat I did hit was when Chicken tried to load a module that I generated from SWIG it failed, unable to find libpcre. I am not sure of the extent to which this is a problem, but here is the fix. As root, run:
# ln -s /usr/lib/libpcre
That solved the problem on my box.
