Now that you've successfully built your demo as explained in the Build Process section, it's time to test it.
What I do is mount my development directory as a virtual hard drive on fs-uae, which gives me instant access to the build files and data.
To run the zoom example on Amiga we move to the directory that contains our executable file and the data directory and simply run it:
The Amiga version takes one command line argument:
demo N: Starts the demo from effect numberN. This will start the music at the appropriate place as well.
As the target depends on BASS, we need to make sure that this library can be loaded.
On Mac OSX we can create a symlink to it in the directory where our demo executable is, like this:
mmendez$ ls -la libbass.dylib
lrwxr-xr-x 1 mmendez staff 42 2 Jun 12:59 libbass.dylib -> ../../third_party/bass24-osx/libbass.dylib
And then simply execute the file:
mmendez$ ./zoom.elf
DEBUG - Memory manager init...done
DEBUG - demoInit()
DEBUG - Starting demo from effect <0>
DEBUG - demoAudioInit()
DEBUG - Loading audio data...
DEBUG - Loading and unpacking data
DEBUG - Loading asset: data/brut_zoom.tndo
DEBUG - Loading Audio asset...
[...]
On GNU/Linux systems the process is similar. There's a script called run-posix-linux.sh that takes care of the library path setup for you:
mmendez$ cat run-posix-linux.sh
#!/bin/bash
LD_LIBRARY_PATH=$LD_LIBRARY_PATH:../startup/third_party/bass24-linux/x64 \
./zoom.elf "$@"
Executing this script will run the demo.
The SDL/Posix version of the demo takes the following command line arguments:
demo -i N: Starts the demo from effect numberN. This will start the music at the appropriate place as well.demo -d: Every frame that has been rendered will be dumped to a file in/tmp. These can then be converted to a video using tools like ffmpeg.demo -r: Start in Rocket mode. The rocket editor needs to be running before you start the demo.
It is possible to use multiple options at the same time, e.g.: ./brutalism.elf -r -i 2 will start the demo in Rocket mode from effect 2.
The shell wrapper used in GNU/Linux passes the arguments to the executable.
