libm with VS2005 and multithreaded dll runtime

alistairmacarthur — Thu, 10 Jan 2008 10:39:39 GMT

nobody seems to know the answer to my last post...but we'll try again with another question:

I am trying to use the intel library "libm" (and its variants) within Microsoft Visual Studio 2005. I can successfully compile and link a simple program using libmmt.lib when linking statically to a multithreaded runtime (/MT compiler switch). However, when attempting to use the /MD switch (so as to use a dynamically linked runtime) I get unresolved symbol errors.I can attempt to patch up these unresolved symbols by adding libc, libcp etc but this introduces multiply defined symbols.

Is there an appropriate version of libm that links to the dynamically linked runtime?

thanks

Did you try to look in Intel compiler documentation? Please see attached picture from main_cls.chm file

Thanks for your reply. I don't have the intel compiler, or the intel compiler documenation. I downloaded the Intel ipp performance library only. The Intel ipp performance library only contains libm.lib andlibmmt.lib.

Do I need to download the intel compiler in order to the libm math functions???
