"Bad CPU Type In Executable"

You need to compile it as a "universal" binary. There's a menu in the project settings where you can select the desirec target architecture(s), in which you'd want to select both powerpc and intel (or ppc and i386, or whatever the labels are in your xcode).

Under the "Project" settings select the "Build" tab. The first item in the list should be "Architectures". Double-click "Architectures" and it should display a sheet allowing you to select PowerPC and/or Intel.

I believe you have to make the change to the "Architectures" setting for each of your build configurations... so, for example, if you made the change while you were working on a "Debug" version of your app and later switched to a "Release" version, built and moved the app across to your other machine... the Release version would not have the dual-architecture setting.

Go back to the "Build" tab in your Project Settings and use the pop-up menu at the top to check both the "Debug" and "Release" configuration to make sure PPC and Intel are set for both of them.

EDIT: Also make sure the "SDK Path" is set to "/Developer/SDKs/MacOSX10.4u.sdk" for both configurations.

Hmm.. I'm not sure what to suggest...

If you select your built application in Finder and do a "File -> Get Info" what does it say next to "Kind:"? It should say "Application (Universal)".

If it doesn't say it's universal then something's still not right with your build settings... Maybe try doing a "Clean" and then another "Build"???

If it does say it's universal... but still gives you the error that it's not built for that architecture... I'm not sure what to suggest... :^(

At this point I'm not sure what to suggest. Maybe your build results window would have some clue. Do a "Build->Clean" on your project, then select "Window->Tools->Build Results" to open the build results window. Then click the "Build" button to rebuild your app.

When I build a Universal binary the build results window shows several "Copying" steps, then a couple of "Precompiling" steps, followed by "Compiling" for each of my .m files, then "Building ZeroLink launcher"... then a second set of "Compiling" steps for each .m (for the second architecture), then another "Building ZeroLink launcher" and finally a "Creating Universal Binary" step.

What are you seeing in your build result window? Do you see the second set of "Compiling" steps?

Steve

Here are a couple of things to check...

First, from your screen shot it appears that the main.m file is from an older AS Studio application (ie is this a project that was originally created some time ago... perhaps under Project Builder?). The main.m file that gets included with relatively new AS Stdio apps looks like this:
<pre>
extern void ASKInitialize();
extern int NSApplicationMain(int argc, const char *argv[]);

int main(int argc, const char *argv[])
{
ASKInitialize();

return NSApplicationMain(argc, argv);
}
</pre>
So you may want to copy/paste the main.m code from a newly created AS Studio app into your (older?) existing project. I'm not sure the above problem would cause the failure to build a Universal app, but changing code in main.m may get rid of the warnings you're seeing.

But also, the screenshot made me wonder if your target(s) needs to be converted to the newer "native" target format (this is different from the "conversion" that Xcode does to an older project file). With your project open click on Xcode's "Project" menu... is the option "Upgrade 'YourTargetName' to Native Target" or "Upgrade all Targets in Project to Native" available? If so, I think you must convert to native targets in order to build universal binaries.

Hope this helps,
Steve
