Unix/Linux

I thought Mac OS X comes with libpng pre-installed. It’s pretty clear that I was wrong after I failed to compile a game that uses libpng. The good thing about OS X is that, you can just use fink to easily install Unix/Linux binaries. However, the weird thing is, the game configuration still complains that libpng could not be found. So I decided to install libpng from the source code. In case anyone of you out there who may face the same problem as me, you could do as what I describe below....

I’m pretty bored today, and I wanna take a break from learning Python. So, I decided to compile an open source game, LBreakOut (L is for Linux), for my PowerBook. In order to compile this game, you need obviously the source code of the game where you can get it from here. Additionally, you need the SDL library, where you can get it from http://www.libsdl.org. Here is the screen-shot of game running on my PowerBook:...

Normally, I would bunzip the file first, then untar it next. But I found something after googling for a shortcut: it can all be done with just one tar command. $ tar -xjvf example.tar.bz2 Notice that, we use j flag to decompress bzip2 file and z flag for gzip file. 🙂

bunzip -v exampleFile.bz2 or bzip2 -dv exampleFile.bz2 bzip2 -h man bzip2 bzip2 homepage
