Is it a C wrapper library (C code compiled into lib) to use LAPACK routines in c ? OR is it the original fortranlib file (Fortran code compiled to a lib).</DIV> <DIV>I understand mkl.h is the (only) header that we need to use all the MKL routines.</DIV> <DIV>I come to this question since I have code that runs fine in VC++ 6.0 but does not run at all with VC++.NET with managed extensions. Any function that doesnt take a char parameter works but the one with char parameter doesnt work. I am wondering if I need to pass the character in fortran style.</DIV> <DIV></DIV> <DIV>Thanks for your patience.</DIV> <DIV>vikrantca</DIV> Sat, 15 May 2004 00:26:39 GMT https://community.intel.com/t5/Intel-oneAPI-Math-Kernel-Library/What-is-mkl-h-and-mkl-c-lib/m-p/958440#M15672 Intel_C_Intel 2004-05-15T00:26:39Z https://community.intel.com/t5/Intel-oneAPI-Math-Kernel-Library/What-is-mkl-h-and-mkl-c-lib/m-p/958441#M15673 <P>MKL is largely independent of compilers.
