Hi all.
I have no experience in fortran at all.
But I need to compile one program :-(
I use debian squeese.
After some googling I tried this command line with following output.
Can anybody tell me what is the problem?


petro(a)cica:~/bin/CDpro/SRC$ fort77 -o cdsstr CDsstr_unix.f
MAIN:
bvpro3:
bvpro4:
rndm:
svd:
ran3:
cdinit:
Error on line 1558: impossible conversion
fctrl:
segment:
message:
plot:

ymin:
rms_nrm:
/usr/bin/fort77: aborting compilation



If I go to line 1558 in emacs it contains this:

Code: Select all
If(Iprint.EQ.1)Print='PRNT'


the full source code is here.

Thanks in advance.

I would suggest to use the gfortran compiler.

If I use the gfortran compiler, it shows the following errors:


CDsstr_unix.f:1558.29:

If(Iprint.EQ.1)Print='PRNT'
1
Error: Can't convert CHARACTER(1) to REAL(4) at (1)
CDsstr_unix.f:1985.19:

facx= float(wavef-wavei)/60.0
1
Error: 'a' argument of 'float' intrinsic at (1) must be INTEGER



The first one is a non-standard use of Hollerith constants; I think the
quickest way to get it compiling it to use:

If(Iprint.EQ.1) Print = transfer('PRNT',print)


For the second one: FLOAT converts integers to real (to floating point
numbers) but wavef/wavei are already implicitly typed real. The simplest
is to simply remove "float":

facx= (wavef-wavei)/60.0


That should be all what's needed to get it compile. No guarantee that
the program is then doing what you want it to do ;-)

second that suggestion...

Actually, I don't think "print" is used anywhere else in the code (at
least that I can see), so the quickest way might be to comment out the
line :-)

Thanks a lot.
It worked.
I will have to compare output from windows program and this one.
But its compiled :-)
Best regards.

I can't imagine the circumstance when a person would have to work around
a hollerith constant. If I read the wiki correctly, it would have been
deprecated by the time f77 rolled along:

http://en.wikipedia.org/wiki/Hollerith_constant

Apparently, Hollerith is the guy who came up with punchcards:
