Hi all,

I'm interested in making an entry for the Saturn programming contest. What's the easiest way to get a dev environment setup on Linux? Jo Engine claims support for Linux, but it's not obvious to me how to use it. Any advice? Thanks in advance.

Sorry for the delayed reply. Yes I cloned the git repo:

git clone johannes-fetz/joengine

In /jo/joengine/Compiler/SH_NONE_ELF/bin there appears to be a compiler sh-none-elf-gcc-8.2.0. I think tried to compile a empty main file that includes jo/jo.h:

./sh-none-elf-gcc-8.2.0 main.c -I ~/jo/joengine/jo_engine

And that fails. Any advice? Thanks in advance.

Hi Antime,

The first errors are related to #defines:
Code:
error: #error "JO_FRAMERATE must be greater than zero"
error: #error "JO_FRAMERATE must be greater than zero"
At the command line I tried defining those two values:

Code:
./sh-none-elf-gcc-8.2.0 main.c -I ~/jo/joengine/jo_engine -DJO_FRAMERATE=30 -DJO_MAX_SPRITE=10
But now I get other errors:

Code:
jo/joengine/jo_engine/jo/sprites.h: In function 'jo_sprite_get_width':
jo/joengine/jo_engine/jo/sprites.h:369:39: error: 'jo_texture_definition' {aka 'struct <anonymous>'} has no member named 'width'
     return (__jo_sprite_def[sprite_id].width);
Lots of those. So not quite sure what's going on.

Thank you, it was embarrassingly simple. All I had to do was run "compile.sh" in one of the sample dirs.

Unfortunately there isn't a straight forward way. Each variant of Linux has a different system. Slackware is possibly easiest since you just write a .SlackBuild and let it compile the program; Slackware is pretty much a GNU BASH driven system so it's transparent to GNU Linux.

I'd recommend you make a .spec file for rpmbuild, for rpm based Linux variants. Or at least an Ebuild for Gentoo's Portage.

That's great things worked for you. Usually you want a sane resulting installable program so you can avoid git and keep track of installed software (e.g. deb, rpm, tbz2, txz, etc). Integrity keeps things transparent under Linux; Linux can be nasty against user preference.

EDIT:
You said any dev environment under Linux so not just Joengine? Consider "Codewarrior" version 4; this one and some others work in Linux.
