Weird.  I am unable to reproduce the problem even when I specify clang as the compiler on my Macbook.  What if you force 64bit on C and C++?  Or can you tell which specific object files (rather than libraries) have the wrong architecture?

Hi Bill,

Complete details can be found here:

Did config.log not show up? I see the attachment in my outbox. 

This is the output of make the second time. Everything is fine until this step but I can attach the whole thing if necessary. 

I tried a dozen or so attempts, all from a completely empty directory (including deleting .libs and such). 

Also, I ran autogen.sh after my clean pull yesterday. 

Best, 

Jeff

Jeff,

Can you send the configure output as well?  It is strange that no files were built.  Does this happen if you do a make clean first?

I'm very happy to accept that this is user error, either due to direct stupidity or indirectly by virtue of something I've done with macports (or using macports in the first place), but I can't figure out how to solve it.  I've made a number of queries to the google oracle to no avail.

I tried the stackoverflow suggestion of -m64 as well as -arch x86_64, but neither worked.

Any suggestions?

Thanks,

Jeff
