Getting started with hamsterdb
To optimize and install hamsterdb on your GNU/Linux distribution, you should download the universal sources archive distributed on Softpedia free of charge, extract it on a location of your choice, open a terminal emulator and navigate to the location of the extracted files.
Execute the “./configure && make” command (without quotes) to configure and compile the project for your hardware architecture, 32-bit or 64-bit. When the compilation process finishes, which will take some time, you can install the software system wide by running the “make install” command (without quotes) as root.
