Linked in FORTRAN 77 (HP-UX)

[Roxana_4]

My names Roxana and I’m from Romania.

I have a HP9000 system with HP-UX 10.20 and with HP Fortran / 9000 (Fortran 77).

I run the following program text77.f :
program afiseaza
print *,’hello’
end

I compile: f77 –v text77.f and this is the result :
/usr/lib/77pass1 – text77.f text77.o
text77.f :
MAIN afiseaza
/bin/ld –x /lib/crt0.o text77.o –lcl –lisamstub –lc

I perform a.out
$ a.out
and this is the result:
sh : a.out : not found.

I edit the link as follows:
ld –v –L –vallcompatwarnings –x /lib/crt0.o text77.o –lcl –lisamstub –lc
The result is
LPATH is : /usr/lib: /opt/langtools/lib

Why?

Of course ./a.out

Why unsatisfied shared lybrary symbols :
main (code) ?

$ ./a.out
and this is the result:
sh : a.out : not found.

Why ?

Thanks

Hello Harry.

Sorry for not being clear!

It works if i do "./a.out".
Why does not function if i do "a.out" and returns error "sh: a.out : not found"
Why i receive error message at linkedit? See:
LPATH is : /usr/lib: /opt/langtools/lib

How could i compile or linked in order to make "a.out" work aut ?

Thank you and best regards.

[harry d brown jr]

does /lib/crt0.o have a "main" in it? It doesn't appear to, thus your program text77 needs to be changed to

PROGRAM main
print *,"hello world"
END

Roxana,
for the a.out to work without ./ you have to have your current directory in $PATH.
Check with "echo $PATH"
If . is missing try "export PATH=$PATH:."
This should fix your a.out problem.
