sdk

[yapple]

I have just started to write some plugins for shake and I am rather confused. The doco's are great at explaining the concepts, and the examples they give seem good but too complex to understand as a rookie. Is there any 'in-between' tutorials or something to get you started?

Thanks

hi,

sorry I can't help you, but hopefully you can help me, I'm trying to find out where I can get a copy of the shake SDK. I'm a student at bournemouth university, UK, and we dont' appear to have the SDK anywhere.

hope to hear from you soon

thanks
Lee

No worries... I have since sorted out my problems... there are a few subtle things needed to get it working which without good doco can be frustrating. Anyway, talking to shake-sdk support @ apple has helped.

As for obtaining the sdk, we have a login to download shake and the sdk from apple (http://shake.apple.com/download/). Your uni should probably have the same story so check with your admin. if not, you can probably contact shake-sdk@apple.com

I am also trying to find good tutorials for the Shake SDK, but I have another problem. I have tried to build the project given as example with no luck. there was a linking problem. Can you help me?

Thanks,
Nilly

Might be helpful if yu provided details of your problem like:
what the linker spits out
&
what your link command looks like

Any suggestions?

Looks like your frameworks are not being recognised. Are they shown in red in the xcode browser window?

[gareefy]

well, it works now , thanks!!!
However, now I have got a plug-in that compiles, but I can't get it into shake.
I've got my .cpp file in the ProjectBuilder, I have modified the pluginUi by adding the following line:
nuiToolBoxItem("@Glow" , Glow(0));
and I have also modified the plugin.cpp file by adding the following line:
"extern image Glow(image);n"
I built the 'sdk' target, and then the installed target.
I copied the plug-in's bundle folder to the startup directory, copied the UI header file into the ui directory, and when I run shake from the command line, the following error occurs: "bus error".

what am I doing wrong?

[mayacner]

Do you get the bus error on starting shake or when you try to load up your plugin? Any messages in your console window?
Also, make sure you are compiling with the right version of gcc. I think that with Shake 3.0x you should use 3.1 on OS X and 2.95.3 on Linux. With 3.5x you should use gcc 3.x on both both platforms - this is form memory so you might wanna check that somewhere in the docs.

[gareefy]

well the bus error appears when I am trying to run shake from the command line. I am using the right version of gcc according to the SDK reference guide. Are there any defined steps to be done in order to run a plug-in? did I forget something?

[mayacner]

There is nothing that springs to mind right now. Are you able to build the example plugins OK and run them without problems?. If you cannot then there is some kind of versioning problem by the sound of things, wrong frameworks with this bin etc.
If you can, then without looking at the code I can only suggest you try first duplicating one of the example plugins and then modifying it bit by bit to see at what stage things go wrong.

[gareefy]

When I build the the example plugins together with mine, shake runs without problems. i guess I did something wrong...
Thanks a lot, Nilly
