Malformed objects in i386 IPP library for Mac OS X

The new ranlib in the XCode SDK supporting iOS4 reveals the problem.

1. Extractippcachesize.o fromlibippcore_i386.a.

2. $ ar -r outlib.a ippcachesize.o

ranlib: object: outlib.a(ippcachesize.o) malformed object (section contents at offset 0 with a size of 4, overlaps Mach-O headers at offset 0 with a size of 528)

Third section confirms this:

$ otool -l 'libippcore_i386.a(ippcachesize.o)'

...

Section

segname __DATA

addr 0x00000300

offset 0 <<<<<<<<<<<<<<<<<<<<<<

align 2^2 (4)

Bjorn,

Unfortunately I can't find any workaround forIPP 6.1 gold
In the IPP 7.0 this problem already fixed. You can use IPP 7.0 beta or wait IPP 7.0 gold, it will be soon.

Best regards, Pavel
