gfortran and lapack problem

[Christian]

Hi all,

I'm having problems setting up gfrortran with lapack. I installed
lapack and liblapack-devel from cygwin, but when I try to compile I
cannot get any result, although I don't get any error. This a very
simple code I'm trying to compile:

PROGRAM MyTest
  IMPLICIT NONE
  DOUBLE PRECISION :: A(2,2) = RESHAPE( (/1, 2, 3, 4/), (/2,2/) )
  DOUBLE PRECISION :: B(2,1) = RESHAPE( (/5, 6/), (/2,1/) )
  INTEGER, DIMENSION(2) :: ipiv
  INTEGER :: n, info
  EXTERNAL DGESV
  PRINT *,'Printing the results'
  CALL DGESV(2, 1, A, 2, ipiv, B, 2, info)
  PRINT *, info
  PRINT *,'End printing'
END PROGRAM MyTest

I compile it as gfortran MyTest.f90 -o MyTest -llapack -lblas. I don't
get any errors (it says "compilation finished"), but the output file
doesn't print anything (neither the strings, or the variable info). If
I comment the "CALL DGESV" line, it does print everything (with
info=0, of course).

Am I doing something wrong or is there any problem in my lapack installation?

Best,
C
