Hello All,
I am building a library with some math functions that are to be integrated with
a codec driver targeting Windows XP. My build environment is DDK 7600.13685.1
The library is built separately and then linked with other libraries to get the
audio driver. I am getting the following errors in the link stage. Does anyone
have an idea why there should be link conflicts, why should native math library
functions have conflicts with libcntpr.lib and ntstrsafe.lib. I tried an
experiment using IPP calls to replace all the calls to sqrt(), but I still get
the same errors.
Would appreciate your responses and any fix for this issue.
-- LINK ERRORS --
1>...\libcntpr.lib(sqrt.obj) : error LNK2005: __CIsqrt already defined in
ntoskrnl.lib(ntoskrnl.exe)
1>...\libcntpr.lib(sin.obj) : error LNK2005: __CIsin already defined in
ntoskrnl.lib(ntoskrnl.exe)
1>...\libcntpr.lib(cos.obj) : error LNK2005: __CIcos already defined in

1>...\ntstrsafe.lib(ftol2.obj) : error LNK2005: __ftol2 already defined in

Thanks and Best Regards
