Compile with -arch flags on OS X

For some reason MacPorts only compiled all those libraries for PPC and
i386, not x86_64. (You can do a 3-way universal binary.)

Our SConscript is detecting that your machine is 64-bit and trying to
link against those libraries, but it can't mix architectures like that
(ie. it can't build a 64-bit Mixxx and link it against 32-bit
libraries unless it's universal).

When you run scons, what is it reporting your Machine as? (It's one of
the first lines of output.)

Try compiling with:

scons machine=i386

and that should force our build system to try building a 32-bit Mixxx.

Thanks,
Albert

Thanks for getting back...
If i remember right i could not get taglib to compile from source on 10.6 , so i switched to macports for convenience.
Lazy arse got the ticket now :-)

"scons machine=i386" gives same error like in my first message.

All went better then expected, macports is not only for i386.

Looks like scons does not get the machine type right, if forced to use x86_64 it builds just fine.
Even with optimize=4, this option never worked for me for some reasons.

Ended up with "scons hss1394=0 machine=x86_64 optimize=4"
