It works for IPP 5.3, both 32bit and 64bit version. Now I'm upgrading the IPP library from 5.3 to 7.0. With IPP 7.0, 32bit version can be built successfully, but 64bit version failed. It has a lot of link errors such as "1&gt;ippsc.lib(pcpsha1ca_split_y8_ippsSHA1Final.obj) : error LNK2001: unresolved external symbol __GSHandlerCheck". How to resolve these link errors?<BR /><BR />Thanks,<BR />Frank Mon, 17 Jan 2011 02:19:01 GMT https://community.intel.com/t5/Intel-Integrated-Performance/Link-error-in-IPP-7-0/m-p/822907#M4907 Frank_Zhong 2011-01-17T02:19:01Z https://community.intel.com/t5/Intel-Integrated-Performance/Link-error-in-IPP-7-0/m-p/822908#M4908 <P>Hi,</P><P>Could be because of issue mentioned it in <A href="http://blogs.msdn.com/b/mgaur/archive/2006/12/21/lnk2019-unresolved-external-symbol-gshandlercheck.aspx"><SPAN style="text-decoration: underline;">MSDN</SPAN></A>?</P><P>Regards,</P><P>Naveen Gv</P> Mon, 17 Jan 2011 09:12:37 GMT https://community.intel.com/t5/Intel-Integrated-Performance/Link-error-in-IPP-7-0/m-p/822908#M4908 Naveen_G_Intel 2011-01-17T09:12:37Z https://community.intel.com/t5/Intel-Integrated-Performance/Link-error-in-IPP-7-0/m-p/822909#M4909 Use new WDK can link 64 bit driver successfully.
