Dear All

I want to run this example : http://software.intel.com/sites/products/documentation/doclib/mkl_sa/11/mkl_lapack_examples/zgesvd_ex.c.htm

to do this i installed "composer_xe_2013.3.163" 

and pathed it as :  "source $HOME/intel/composer_xe_2013.3.163/bin/compilervars.sh ia32" in .bashrc

then to compile the program, the command line in the terminal is : $ gcc zgesvd.c

but it cant realized the zgesvd as below :

$ gcc zgesvd.c

/tmp/ccJyWTh0.o: In function `main':
zgesvd.c:(.text+0xeb): undefined reference to `zgesvd'
zgesvd.c:(.text+0x1b1): undefined reference to `zgesvd'
collect2: error: ld returned 1 exit status 

how can i fix this problem?

Sourcing the shell script for the Intel compiler is done in preparation for using the Intel compiler. To build an example using the Intel C compiler, the command is [bash]icc -mkl zgesvd.c[/bash].

If you really wish to build using gcc instead, you may need to use additional optional arguments or set up a suitable environment yourself.

Hi,

As suggest by mecej4, adding "-mkl" is easy way for icc.  If you are using the gcc, the following tools may provide some help on the libraries needed for the application:

You have to check each of the three boxes in the acceptance agreement. After you have done that, the ACCEPT button will become active.
