Compilation issue on Mac OSX 10.6 ?

[David Bouchard]

Has anyone been able to compile LightBlue on Snow Leopard?  I'm fairly new to Mac OS so I could be doing something wrong.  I managed to get LightBlueAqua to compile by changing the XCode build settings so that it uses the 10.4a sdk + GCC 4.0.  The compile + install works fine, however when I try to import lightblue, I get a "Bundle could not be loaded error".  The problem seems to be traced back to LightAquaBlue not matching my architecture:

Error loading /Library/Frameworks/LightAquaBlue.framework/LightAquaBlue:  dlopen(/Library/Frameworks/LightAquaBlue.framework/LightAquaBlue, 265): no suitable image found.  Did find:
/Library/Frameworks/LightAquaBlue.framework/LightAquaBlue: mach-o, but wrong architecture
/Library/Frameworks/LightAquaBlue.framework/LightAquaBlue: mach-o, but wrong architecture
ERROR: An unexpected error occurred while tokenizing input

I also tried to compile using GCC 4.2 and the 10.6 SDK, same thing.  Tried selecting different architectures in the build settings (Intel 64-bit, Universal 32 or 64 bit) but I get the same result every time.

Any ideas? I would really like to use lightblue and not have to do straight-up PyObjC and BluetoothIO

Thanks!

I had some trouble installing the package and got around the error you have using:

    arch -i386 python2.6

Seems like its defaulting incorrectly. I now have a problem when importing:

    File "/bluetooth.py", line 17, in <module>
        import lightblue
      File "/Library/Python/2.5/site-packages/lightblue/__init__.py", line 160, in <module>
        from _lightblue import *
      File "/Library/Python/2.5/site-packages/lightblue/_lightblue.py", line 398, in <module>
        class _AsyncDeviceInquiry(Foundation.NSObject):
    TypeError: Error when calling the metaclass bases
        class _AsyncDeviceInquiry does not correctly implement protocol IOBluetoothDeviceInquiryDelegate: the signature for method deviceInquiryComplete:error:aborted: is v@:@iB instead of v20@0:4@8i12Z16

Hi rayscan,

Can you please confirm what changes you made to the xcode project before you were able to build it successfully with "arch -i386 python2.6"?

I'm trying to see how this can be built so I can look at the import error.

Looks like the simplest way to fix this was to create a brand new xcode project.

I've added instructions to the home page at http://lightblue.sourceforge.net for building LightBlue on Mac OS 10.6.
