Open source cross-platform development methods and tools

This is an article I’ve been wanting to sit down and write for a few years now. I first started developing software in the late ’90s and got myself a Borland C++ compiler, which I quickly realized was only really going to work on Windows. I made a few small command-line applications at first and then started experimenting with graphical applications. I loved the creative process, but was disappointed by many of the tools. At the time, I didn’t really move beyond adapting simple examples.

A little later, I got interested in developing web applications and started playing with a new language called PHP after being dissatisfied with Perl. I liked how I could mix code and HTML quite freely and have full access to the server machine from the PHP language. I developed a few sites in PHP and played with various ways of pushing some of the processing to JavaScript when possible. This was all pretty nascent, but coupling it with a database let me accomplish quite a lot. I also started participating in mailing lists, answering questions, and learning all I could about how this open source language was developed.

After that I got a little distracted with Linux, packaging applications, and porting to a new 64-bit architecture as a Gentoo developer. That was a lot of fun, and I learned a lot about dependencies, security updates, shared libraries, and how bad many scientists were at writing build systems. Throughout this period, I also learned about being part of an extended online community and had the opportunity to work with a lot of very dedicated and skilled people.

C++ and native development

Ultimately, I realized I wanted to develop software, and really wanted to develop in a native language where I had access to the hardware. At the time I used Linux as my main operating system, but also worked with people using Windows and Mac OS X on a regular basis. I wanted them to be able to use the software I developed, and didn’t want to write it three times. This was when I started aligning on a software stack, largely influenced by KDE and the opportunity I had to do a Google Summer of Code project with them. It is now about nine years since I did that Google Summer of Code project, and I am largely using the same stack with some additions/updates to facilitate collaborative, open source, cross-platform development.
