I am wrestling with fortran and at this point , loosing.
I have a large program that I need to get running. It is
built with a "make install" command that invokes f77.
I am running T64-4.0F and the fortran came installed.
at first the make would halt with:
compiling: f77 -assume backslash -automatic -arch ev56 -O4 -assume noac -math_library fast -align
dcommons
f90: Error: Unrecognized keyword "backslash" for option "-assume"
*** Exit 1
I then found that : /usr/bin/f77 -> /usr/lib/cmplrs/fort90/fort90
and that 'assume backslash' is f77 (real f77) only.
so, according to the man pages I defined "setenv DECFORT /usr/lib/cmplrs/fort/decfort"
placed that into the /etc/csh.login file but still got the same "backslash unrecognized" error
I redefined /usr/bin/f77 so that it pointed to /usr/lib/cmplrs/fort/decfort .
this worked on a test case run from the command line; no backslash error
(where there had been a backslash error before).
so, thinking that my troubles were over, I then tried the "make install" and then got the error:
fort: Error: Unknown option "-c"
Now, this is nonsense. -c is a very commonly used option.
Evidently,somthing is not configured correctly, and I don't seem to find
any helpful instructions anywhere. How do I get full and accurate
access to real f77?
btw, the program really does require the use of the backslash option.
Thanks
