1) You need a newer version of Xcode.

2) FlickrExport is open source, but it depends on the FlickrKit library, which isn’t. There are many instances of flickr.com’s hostname hardcorded in FlickrKit.

Thanks, Guan.

svn co http://speirs.org/svn/FlickrKit/trunk gets you FlickrKit.

I have it *almost* working, but now I’m stuck.

I managed to compile the thing, and even produce a .dmg with the installer. But then when I open iPhoto, it doesn’t work, and my console says this:

2005-11-16 09:47:50.388 iPhoto[5638] *** -[NSBundle load]: Error loading code /Applications/iPhoto.app/Contents/PlugIns/FlickrExport.iPhotoExporter/Contents/MacOS/FlickrExport for bundle /Applications/iPhoto.app/Contents/PlugIns/FlickrExport.iPhotoExporter, error code 4 (link edit error code 4, error number 0 (Library not loaded: @executable_path/../Frameworks/Growl.framework/Versions/A/Growl
Referenced from: /Applications/iPhoto.app/Contents/PlugIns/FlickrExport.iPhotoExporter/Contents/MacOS/FlickrExport
Reason: image not found))
2005-11-16 09:47:50.388 iPhoto[5638] Not a valid plugin: /Applications/iPhoto.app/Contents/PlugIns/FlickrExport.iPhotoExporter

If I leave everything in the plugin, and just replace the FlickrExport with the one that Fraser does, then it works. Switch back to mine and it doesn’t.

So it’s something about the linking that I can’t figure out. I’ve tried with both the precompiled growl SDK, and with a compile-from-scratch, same result.

How can I see what libraries a binary links to? Anything else I can try? If you want me to help you get this setup on your machine, let me know, there was quite a bit of detective work in getting everything working this far.

Guan helped me get to the next step.

Here’s what otool -L says about mine:

FlickrExport:
/System/Library/Frameworks/Cocoa.framework/Versions/A/Cocoa (compatibility version 1.0.0, current version 11.0.0)
/System/Library/Frameworks/Carbon.framework/Versions/A/Carbon (compatibility version 2.0.0, current version 128.0.0)
@executable_path/../Frameworks/Growl.framework/Versions/A/Growl (compatibility version 1.0.0, current version 1.0.0)
@executable_path/../PlugIns/FlickrExport.iPhotoExporter/Contents/Frameworks/FlickrKit.framework/Versions/A/FlickrKit (compatibility version 1.0.0, current version 1.0.0)
/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 88.1.2)

And here’s what it says about Fraser’s:

FlickrExport:
/System/Library/Frameworks/Cocoa.framework/Versions/A/Cocoa (compatibility version 1.0.0, current version 11.0.0)
/System/Library/Frameworks/Carbon.framework/Versions/A/Carbon (compatibility version 2.0.0, current version 128.0.0)
@executable_path/../PlugIns/FlickrExport.iPhotoExporter/Contents/Frameworks/Growl.framework/Versions/A/Growl (compatibility version 1.0.0, current version 1.0.0)
@executable_path/../PlugIns/FlickrExport.iPhotoExporter/Contents/Frameworks/FlickrKit.framework/Versions/A/FlickrKit (compatibility version 1.0.0, current version 1.0.0)
/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 88.2.1)

Note how @executable_path needs to be relative to iPhoto, not to the plugin. And note also how even I have the right path for FlickrKit, but not for Growl.

How do I coerce Xcode into doing the right thing here?

grr – sill Ajax posting thingamy crashed my firefox, so here goes again!

I don’t know why the Growl link path doesn’t match the (correct) one for the FlikrKit framework, but you can manually solve the problem like so:

PowerBook-G4$ otool -L FlickrExport
FlickrExport:
/System/Library/Frameworks/Cocoa.framework/Versions/A/Cocoa (compatibility version 1.0.0, current version 9.0.0)
/System/Library/Frameworks/Carbon.framework/Versions/A/Carbon (compatibility version 2.0.0, current version 128.0.0)
@executable_path/../Frameworks/Growl.framework/Versions/A/Growl (compatibility version 1.0.0, current version 1.0.0)
@executable_path/../PlugIns/FlickrExport.iPhotoExporter/Contents/Frameworks/FlickrKit.framework/Versions/A/FlickrKit (compatibility version 1.0.0, current version 1.0.0)
/usr/lib/libmx.A.dylib (compatibility version 1.0.0, current version 47.1.0)
/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 71.1.3)

PowerBook-G4$ install_name_tool -change @executable_path/../Frameworks/Growl.framework/Versions/A/Growl @executable_path/../PlugIns/FlickrExport.iPhotoExporter/Contents/Frameworks/Growl.framework/Versions/A/Growl FlickrExport

PowerBook-G4$ otool -L FlickrExport
FlickrExport:
/System/Library/Frameworks/Cocoa.framework/Versions/A/Cocoa (compatibility version 1.0.0, current version 9.0.0)
/System/Library/Frameworks/Carbon.framework/Versions/A/Carbon (compatibility version 2.0.0, current version 128.0.0)
@executable_path/../PlugIns/FlickrExport.iPhotoExporter/Contents/Frameworks/Growl.framework/Versions/A/Growl (compatibility version 1.0.0, current version 1.0.0)
@executable_path/../PlugIns/FlickrExport.iPhotoExporter/Contents/Frameworks/FlickrKit.framework/Versions/A/FlickrKit (compatibility version 1.0.0, current version 1.0.0)
/usr/lib/libmx.A.dylib (compatibility version 1.0.0, current version 47.1.0)
/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 71.1.3)

PowerBook-G4$

the install_name_tool command is in my path as /usr/bin/install_name_tool.

If you can’t figure out how to make Xcode/gcc link it right in the first place, I don’t see aproblem with adding this command to a script step in the build process.

You rock! Thanks so much for figuring out how to solve this.

Sorry about crashing your browser.

Here are some instructions I receieved straight from the horse’s mouth (Fraser):

1. .xcodeproj files are only supported in (IIRC) Xcode 2.2 and later.

2. You need to build your own version of Growl – the precompiled one has an incorrect (for our purposes) install path. You can:

2.1 Check out a particular tag of Growl from svn. I usually pull the latest release (0.7.4 right now?)

2.2 Open the Growl project and set the value of INSTALL_PATH for the Growl.framework target to:

@executable_path/../Contents/PlugIns/FlickrExport.iPhotoExporter/Contents/Frameworks/

3.Make sure the FlickrExport project references that framework (and make sure it gets copied into Frameworks/ in the Copy Files build phase.

I’ve been trying to compile FlickrExport 1.3.4 and I’m having the same problems with the Growl error thing… I really don’t know much about what I’m doing… Where do I find the Growl source if I need to compile my own version?

Thanks!

I found the Growl Source… Now I’m trying to compile it for myself… which file do I change the target in??? I’m referring to what you describe in post #7…

I never acually got around to compiling this, since right after Fraser told me about it, he released FlickrExport with 23 support himself. I’d switched to a new computer, and getting this all setup for compilation when normally I don’t do any Xcode stuff was just too painful. Sorry.
