Whew, ok!

Sorry for the delay - I don't usually spend my thursday nights like I did last night. I'll be posting instructions here if anyone wants to follow in my footsteps. However, I have to say that there's at least one show-stopping issue with the mac build. This is to be expected; I just got it working yesterday! But maybe if I get some people to build it on their macs, they can help troubleshoot? Anyhow, let me describe the bugs before we get started:

1. delete key inserts characters instead of deleting. severity: way low, should be easy to fix with some key remapping - in the mean time use control-H to delete.

2. full screen mode shows incorrect colors for some sprites and menus. severity: medium. This is due to the difference between windows/linux's 16-bit graphics mode and mac's 15-bit graphics mode. There's a couple of ways to go about fixing this...the easiest would be to tell IVAN to go into 32-bit fullscreen mode, as it works fine in my desktop windowed, which is 32-bit.

3. 'bus error' when descending into town or dungeon. This is a show-stopping error. While it exists, us mac users can only walk back and forth on the world map Sad

I haven't done much looking at this error yet but if I had to guess, I might say it's an endian issue with the dungeon-generating code.

Now I know we can figure these issues out, but they're not figured out as of yet. So with that disclaimer, if you still want to compile IVAN for mac, keep reading:

(this was tested on a power mac g4 running os 10.3.9. Not sure if tiger is compatible fully with fink yet. Also, make sure you have the latest developer tools installed. They can be obtained from http://developer.apple.com for free.)

A. Install Fink. Fink is a linux-style package manager for os x. It allows many linux-style libs and apps to run in os x easily. Fink is somewhat geared towards power users but if you are running 10.3 there should be no issues. After you have fink installed and everything seems peachy, use FinkCommander to search for any package matching 'sdl'. There should be a small handfull of sdl-related packages. Select them all. Choose to 'install from source', using the toolbar button near the top left. I am not sure if it's necessary to install from source as opposed to binaries, but this is the way I did it.

This might take a bit depending upon your computer's speed and available ram. It's building these SDL (Simple Direct media Layer) libs from source. You might be wondering, "hey lenox, why don't i just download SDL's mac os x installer from their website?" Well, when IVAN is fully macosx-ready, you'll be able to, but not yet. Its configure script doesn't know to look for macosx-specific features.

Ok, so now we have the libs that IVAN depends upon installed happily.

B. Download the IVAN sources and expand them onto your desktop either with Stuffit, or the command line utility 'tar'. You should have a folder full of stuff. Now I am going to assume a moderate familiarity with unix shell before I go much farther, but will try to make it legible for others, too.

a) in the finder (or terminal if you are happier there), navigate to 'ivan-0.50/Main/Source' and open 'main.cpp'. Now, we're going to insert 2 lines after the line near the top that says '#include "feio.h"', and before '#include "igraph.h"'.

Here are the lines to add:

Still working on the endian issues...learning a lot about SDL and big vs little endian architectures! I thought I would post some screenshots of IVAN running on my mac to show people who don't have macs or who don't really want to compile an incomplete version (I don't blame you!)

Here was the first screen I was greeted with...awesome!

Then this...

Here's an actual gameplay shot, but unfortunately you can't go much farther than this...

which explains this!

Finally, here's a full-screen shot (scaled down for sanity) as an example.

edit: ehh, don't worry about this... it was just that Tiger and XCode 2.1 use gcc 4.0 by default.

The IVAN devs are awesome! We'll have something that works very soon!

Ok...cvs version of IVAN finally compiled on Tiger. One of my three noted errors was fixed by the wonderful IVAN devs! The color issues in fullscreen are 100% gone and IVAN looks beautiful!

I think with the knowledge I gained in the past few weeks I could fix the 'delete' key problem easily. As for the other issue...I have faith that'll be sorted out soon, too!
