Exult Forum

Hey all,

[obligatory first post nonsense] I've been an Exult fan for years now, having (finally) played through all of Ultima 7 using Exult a few years back.

I've worked on a mod using earlier versions of Exult Studio on Windows and want to revisit the project on a Mac, so I'm looking to compile the system under OSX.

The problem I'm having is one that I was able to resolve for earlier compilation steps by #including SDL.h in those files, but that's not working for this error.

When I run make, it gets through about half of the files, but then stops dead on this step:

Again, I've tried explicitly #including SDL.h and also pngio.h (where Export_png8 is defined) to the shapelst.cc. Are there any libraries or include files that I'm clearly missing that may be causing this?

Has anyone else encountered this compilation error? I suppose I could use Exult Studio on a Windows machine using the binary distro or build it for Linux, but I'd rather build my mod on my Mac, since that's the machine I have when I'm out of the house.

Thanks in advance for any tips on how to build this.

Note: I am a fairly experienced C++ programmer, though I've mostly worked in Python for the past few years. I've tried a number of tricks that have worked in other scenarios, but nothing has seemed to work.

strange, that you needed to explicitly include SDL.h. This indicates to me that some of your includes or paths weren't complete/correctly since I can compile fine on OS X without changing anything in Exult's source. If I see this correctly you are using homebrew or so to get your stuff working (the /usr/local/cellar/... is my only indication). Maybe there is something wrong in the homebrew setup. I never tried that. I can only say it works nicely for using MacPorts or my own prefix.
As a starting point, to start compiling with my own prefix (/opt/exult.x86_64) I set the following environment: You need to adapt this for your prefix (/usr/local/cellar/...).

The error points at libpng. Maybe get that from homebrew as well.

Anyway, problem is on your side
