Malformed objects in i386 IPP library for Mac OS X

[bjorn_topel]

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

sectname __bss

segname __DATA

addr 0x00000300

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

align 2^2 (4)

reloff 0

Hereare some related information for your reference,
Where to download IPP for Mac OS:
http://software.intel.com/en-us/articles/performance-tools-for-software-developers-how-can-i-download-the-intel-ipp-and-intel-mkl-for-mac-os-x/

Which version of Intel IPP, Intel MKL and Intel TBB is installed by the Intel Compiler Professional Edition?

Regards,
Ying

Certainly, should have added this in my first post.

IPP: 6.0.1.071.

Apple Mac OS X: 10.6.4

@Ying Do you need any more information?

Hello Bjorn!

I will look at this problem.

Thanks, Pavel

[Pavel_B_Intel1]

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
