I am new to healpix and would like to create a program that reads in alms form a fits file. Here is my test code I am trying:

Code:
program test
use healpix_types
use fitstools
implicit none
integer(I4B) :: nside, lmax, mmax, npix, n_plm
complex(SPC), dimension(:,:,:), allocatable :: alm
character(len=80), dimension(1:80,1:3) :: header
nside=512 ; lmax=1024 ; mmax=lmax
allocate(alm(1:3,0:lmax,0:mmax))
header = ''

call fits2alms('alm_7.fits', 65*66/2, alm, 3, header, 80, 3)
end program test


I am trying to compile like this:

Code:
ifort -O test.f90 -L/home/jsmidt/lib/healpix -I/home/jsmidt/include/healpix  -L/usr/local/cfitsio/lib -lhealpix -lcfitsio -o ./test


Which then gives me this error:
Code:

fortcom: Error: test.f90, line 12: There is no matching specific subroutine for this generic subroutine call.   [FITS2ALMS]
call fits2alms('alm_7.fits', 1023*1024/2, alm, 3, header, 80, 3)
-----^
compilation aborted for test.f90 (code 1)


Would someone mind helping figure out how to get this program to work? I am confused because it states "no matching specific subroutine for this generic subroutine call" and yet the healpix website makes it sound like this is a subroutine from fitstools: http://healpix.jpl.nasa.gov/html/subroutinesnode28.htm.

Thanks.

Hi!

I have a similar problem. I'm trying to compile sky_ng_sim.f90 with a modification (I put a 'call dump_alms') and the same error appears: "sky_ng_sim_bin_cunha.f90(485): error #6285: There is no matching specific subroutine for this generic subroutine call. [DUMP_ALMS] ".

Have you already solved your problem? Could you tell me how you did it?

Thank you,

Mariana

Hi, I just want to post a possible solution for this compilation error. ifort and gfortran give this kind of error when a variable that goes inside the Healpix routine has been declared with a different type in the main program than the one specified by Healpix.
