[Buildroot] clapack libraries missing?: buildroot-2014.11

[Buildroot] clapack libraries missing?: buildroot-2014.11

[Williams]

Hi,

I am using "buildroot-2014.11"
I am using glibc and my target is INTEL x86_64
Version of CLAPACK:
CLAPACK_VERSION = 3.2.1

I would like to use clapack but missing the following libraries after the install:

***********************
(1) lapack_LINUX.a
(2) blas_LINUX.a
(3) libF77.a
(4) libI77.a
************************

For includes I am also missing:
*************************************
"f2c.h"
**************************************


The only library, I see in the staging area is the following shared library:
=============================
liblapack.so
=============================


Cheers,
Ernesto

 libblas.so should also be installed. And the header file is called clapack.h

 The f2c functionality is linked into these shared libraries, it shouldn't be
necessary to include or link with anything else.

============================================================
Okay, this is whta I have:

[ernesto at icd-pc90626 lib]$ ls liblapack*
liblapack.so*
[ernesto at icd-pc90626 lib]$ ls libblas.so
libblas.so*
[ernesto at icd-pc90626 lib]$ ls ../include/clapack.h
../include/clapack.h

I will run a test example this evening for a try.

Thanks again.

Ernest

 libblas.so should also be installed. And the header file is called clapack.h

============================================================
Okay, this is whta I have:

../include/clapack.h

I will run a test example this evening for a try.
========================================


My code does not compile:
clapack has types that are not defined :(

What other header file defines, "integer, "complex", "doublereal", "logical" , etc  ...?

/* header file for clapack 3.2.1 */

#ifndef __CLAPACK_H
#define __CLAPACK_H

/* Subroutine */ int caxpy_(integer *n, complex *ca, complex *cx, integer *
        incx, complex *cy, integer *incy);



Looks like  "f2c.h" is actually needed but was not installed.

Here is a small snippet from  "f2c.h" below:

*************** BEGIN Snippet from f2c.h  ***********************************
/* f2c.h  --  Standard Fortran to C header file */

/**  barf  [ba:rf]  2.  "He suggested using FORTRAN, and everybody barfed."

	- From The Shogakukan DICTIONARY OF NEW ENGLISH (Second edition) */

#ifndef F2C_INCLUDE
#define F2C_INCLUDE

typedef long int integer;
typedef unsigned long int uinteger;
typedef char *address;
typedef short int shortint;
typedef float real;
typedef double doublereal;
typedef struct { real r, i; } complex;
typedef struct { doublereal r, i; } doublecomplex;
typedef long int logical;
typedef short int shortlogical;
typedef char logical1;
typedef char integer1;
#ifdef INTEGER_STAR_8	/* Adjust for integer*8. */
typedef long long longint;		/* system-dependent */
typedef unsigned long long ulongint;	/* system-dependent */
#define qbit_clear(a,b)	((a) & ~((ulongint)1 << (b)))
#define qbit_set(a,b)	((a) |  ((ulongint)1 << (b)))
#endif

**************** END Snippet from f2c.h **************************************


*******************************************************
The application code is a simple example shown below:

#include <clapack.h>
#include <math.h>
#include <stdio.h>
#include <stdlib.h>


#define NDIM 4 

int main (){

int i, j, info2;
int N, NRHS, LDA, LDB;
double *A;
double *B;
static int IPIV[NDIM], INFO;

A = (double*) malloc(NDIM*NDIM*sizeof(double));
B = (double*) malloc(NDIM*sizeof(double));

N=NDIM; NRHS=1; LDA=NDIM; LDB=NDIM;

A[0] = 1.0;
A[4] = -1.0;
A[8] = 2.0;
A[12] = -1.0;
A[1] = 2.0;
A[5] = -2.0;
A[9] = 3.0;
A[13] = -3.0;
A[2] = 1.0;
A[6] = 1.0;
A[10] = 1.0;
A[14] = 0.0;
A[3] = 1.0;
A[7] = -1.0;
A[11] = 4.0;
A[15] = 3.0;
    
    for (i=0;i<N;i++){
       for (j=0;j<N;j++) {
         printf("   %f  \n",A[i+N*j]);
       }
    }

   B[0] = -8.0; 
   B[1] = -20.0; 
   B[2] = -2.0;
   B[3] = 4.0;


   dgesv_(&N, &NRHS, A, &LDA, &IPIV, B, &LDB, &INFO);

printf("info %d \n",INFO);
 
   for (i=0;i<N;i++)
      printf("   %f \n",B[i]);
}

 [Ernesto, any chance of configuring your mailer to do proper quoting?]

 Could you find out from upstream how to make sure that f2c gets installed as
well? Perhaps also ask them to include f2c.h from clapack.h.
