MKL on command line

quantum_penguin — Wed, 26 Jul 2006 05:21:40 GMT

Hello,

I have the Intel Compiler with MKL, but I do not have Visual Studio or the like and thus must use the command line. This is not familiar to me at all.

Some sample code ('hello world' variety) has compiled fine, but the sample programs that use MKL functions do not work.

Specifically, I tried to compile,

C:Program FilesIntelMKL8.1examplesvslcsourcevdrnguniform.c and got the error 2019 unrecognized external for vslRngUniform and the like.

vdrnguniform.obj : error LNK2019: unresolved external symbol _vslNewStream referenced in function _main

vdrnguniform.obj : error LNK2019: unresolved external symbol _vslRngUniform referenced in function _main

vdrnguniform.obj : error LNK2019: unresolved external symbol _vslDeleteStream referenced in function _main

vdrnguniform.exe : fatal error LNK1120: 3 unresolved externals.

The command I used to compile it was "icl.exe vdrnguniform.c"

Thanks for the help!

Even when you have the MKL library directory path, you still must name the libraries you want in your compile command, e.g.
icl -Qopenmp yourfile.c mkl_em64t.lib (if using the x64 icl).

I tried this command with exactly the same error (with and without the -Qopenmp):

C:code>icl -Qopenmp uniform.cpp "C:Program FilesIntelMKL8.1ia32liblibgui
de40.lib" "C:Program FilesIntelMKL8.1ia32libmkl_ia32.lib"

Alright,

I did get SOMETHING to compile with this command:

C:code>icl -Qopenmp uniform.cpp "C:Program FilesIntelMKL8.1ia32libmkl_c
.lib"

but it did this...

The program seemed to work, but I'm not so sure I'm really linking the proper library. This was found by trial and error, and that warning sort of scares me.

Thanks again for the help!
