r5872 fails to build on Mac 10.6.4 [fixed]

[RyanLeiTaiwan]

Hi, I checked out the SVN today, upgraded STK's dependencies, then I encountered these linking errors from Xcode:

{l Code}: {l Select All Code}

Basically they're "symbols not found" errors regarding the class "WorldWithRank".
Anyone know how to fix these?

My dependencies:
1. pre-built dependencies - for latest STK trunk/more recent alphas/betas - downloaded from the project website.
2. irrLicht 1.7.1
3. gettext from MacPorts (gettext @0.18.1.1_2+universal)

And my Config.xconfig settings:

Hi,

thanks, that's a known issue, Auria haven't had time to update the xcode project file since my commit yesterday.

You can probably quickly fix this yourself - just add the two files .../src/modes/world_with_rank.?pp to the xcode project file, and it should work.

Cheers,
Joerg

Thanks for the QUICK reply. I added these two existing files, but there's still 1 error:

Hi,

I updated the Xcode project in SVN. I don't get the error about AT_byte_size however, please try a clean build

I still had this "has multiple AT_byte_size attributes" problem after updating with SVN. After googling quite some time, I found out it's a bug with Xcode 3.2.3 and has been discussed several times.

It basically points to the debug symbol linker (dsymutil) of GCC shipped with Xcode. And in Xcode 3.2.3, it comes with a buggy version of dsymutil. Let me list some references:

[1] points out the problem with GCC shipped with Xcode 3.2.3.
[2] suggests extracting the old dsymutil in Xcode 3.2.1 to replace the current one.
[3] even provides the old dsymutil I need!

Conclusion:
If you use Xcode 3.2.3 and encounter "has multiple AT_byte_size attributes", first try to use gcc 4.2 if no backward compatibility problems. If that fails again, follow [3] and replace the dsymutil with an earlier version.

It finally works for me. Thanks, anyway!
