iphone player (2011.9 beta3) linker error

zenpho

Hi there,

Please could someone help me solve a problem with the GiderosiPhonePlayer?

----
Although I have a jailbroken test iPhone I am convinced that the jailbroken-ness is not the cause of the problem here. I have successfully deployed other software to this test phone with the iOS SDK.

I discovered Gideros Mobile (and Gideros Studio) when searching for rapid application prototyping tools.
The fact that one can develop in Gideros Studio then deploy to Android and iPhone with minimal fuss is fantastic!
My test code is running on the Gideros Player (desktop) and in the Android player on my android test phone.

----
My problem is that I receive the following linker errors when attempting to build the GiderosiPhonePlayer:

Has anyone seen this before?

The first error is...

I wonder what can be done to solve the problem. I am keen to test on both iPhone and android platforms.

Did you add the include files?

atilim

can you download beta8 and try it: http://88.198.22.6/downloads/beta/

I may forget changing the linkage of GameKit.framework as weak.

MikeHart

Do you have an apple dev account? Because you need it to use GameCenter.

Thanks for the amazingly speedy responses Mike and atilim...

Thanks for the suggestions Mike. Unfortunately it's not the inclusion of sourcecode before compilation, nor the transfer to the device which is a problem. It seems the problem is to do with the linking of libraries. ;o(

I will download the beta8 version and try this at once.

Hi again,

The 2011.9 beta8 version of the iphone player xcode project compiles and links without a problem. Yay! ;o)

Thanks again for the quick response. Very much appreciated indeed.
