"The GameBoy Developer's Kit (GBDK), is a set of tools that enable to develop programs for the Nintendo GameBoy system, either in C or in assembly. GBDK includes a set of libraries for the most common requirements and generates image files for use with a real GameBoy or with an emulator like VGB or no$gmb. [...]
- An ANSI C compiler.
- An assembler that generates relocatable code.
- A peephole optimiser.
- A linker that produces GameBoy image files.
- Support for multiple-bank images.
- Smart linking.
- A set of libraries, with source code.
- Example programs in assembly and in C."
The base version (2.96a) was downloaded from the official site. Although this is the latest version, it was released quite a while ago (back in April 2002).
The code can be compiled in an up-to-date 64-bit Linux environment (at least it is up-to-date here in 2016).
For the build I recommend an Ubuntu 16.04 LTS (you don't even need to install it, the Live system works just fine).
The environment will need a few packages, all of them can be installed using apt-get:
sudo apt-get -y install make gcc g++ bison flex
After downloading the source you can use the Makefile to compile the binaries:
cd /path/where/you/extracted make
Installing the compiled binaries can be done via make as well:
sudo make install
Compiling the examples:
cd ./gbdk-lib/examples/gb make
Note: compiling the examples requires you to install the binaries you just built in the previous steps.
