non-pic linking model possible?

ryalamanchili — Thu, 16 Dec 2004 02:17:47 GMT

Hello,

I noticed that the intel's libipp*merged.a are compiled in PIC format (like -fPIC flag of gcc). I would like to use this library in vxworks and the linker in vxworks doesnt support PIC code. It complains about undefined _GLOBAL_OFFSET_TABLE_ symbol. I am wondering how I can obtain a non-PIC version of the library or if there is anyway i can manually set the _GLOBAL_OFFSET_TABLE_ to some value and fix the problem?

thank you,
r

Hi,

yes, IPP libraries are compiled to be postion-independed. It is needed for supporting the newest LInux kernels. It also needed to provide ability to build custom DLL for users. So, there is no way to use IPP on vxworks.

Hey,

Thanks for your answer. Do you think you can provide me with the intel ipp compiled in a non-PIC version please, or if there are any plans for such releases?

Thanks,
Ram

No, we do not have plan for such release and can't provide such build for you. Please submit your request on premier.intel.com site, we will consider your request.

Hello,

I'm glad to inform you that since that time we start to release IPP (from v5.1)for Linux in both variants (non PIC and PIC). The latest available version now is IPP v5.2 beta
