LAPACK linking...

[ashesh]

I have Linear Algebra PACKage, (LAPACK) installed in my computer as I had opted for it during installationof Linux RH8.0. I need to use some of the routines in this package. These routines can be used along with fortran... I need to link the LAPACK when I compile the fortran program... It seems to be similar to linking the math.h files when I say
cc filename.c -lm

Can someone let me know how I can link the lapack routines to execute my fortran programs?

Thanks in Advance...

Hi Salem,

It was very urgent for me to know the answer and I couldn't think of a better place to post...

I read that I need to use g77 prog.f -ldxml,
but that wouldn't work...

Could u let me know of a forum like this one where fortran/numerical stuff are discussed?

Finally could compile my program that call LAPACK subroutines.

To compile a program that calls LAPACK subroutines use "-llapacl" ie.,

g77 filename.f -llapack

If "BLAS" subroutines are also called, then use:

g77 filename.f -llapack -lblas

One more problem I faced during compiling is as follows:

In "C" , we can include the files which contain the subroutines that we need by saying
#include "filename.h"

In fortran, I have not been able to use include statement. But we can compile by giving the path/file of all the files that have the subroutines.

g77 filename.f /home/ashesh/fortran/file1.f /home/ashesh/fortran/file2.f -llapack

is equivalent to including all the program which have the functions I need to call.
