from unix to linux

[let1ch]

Hi,
I'm trying to compile with ifc a program (f77), previously working just on unix machines (it's not a long time I use compilers).
With the options -O2 -Vaxlib -w -WB -o
I can compile all my subroutines except two external functions, for which I obtain the errors
"Error 294 : Function TOCMPLX has not been given a result value"
and
"Error 294 : Function TOIMAG has not been given a result value"
Those functions work well in unix (where I compile with
f77 -xO3 -xarch=v8 -dalign -o);
if I define a value for them, I can compile, but then the program runs without stopping and doesn't give results.
I could't find an option in the user guide to solve this problem, could someone help me?

I doubt an "option" is going to help. You need to debug the program to find out what is going wrong. I find it curious that you were able to run successfully before with functions that never defined their values.

I also note that you use -WB which disables array bounds checking - if you get array bounds errors without -WB, I think that's trying to tell you something...

According to your description, it's unlikely that your program would have worked with the usual Unix f77 compilers, most of which have a resemblance to g77.
Options which could be useful in pointing out further problems, where your program deviates from Fortran, include -g -C.

I got the same problem when compiling a few thousand fortran modules under hp-ux and two failed with this very error.

A workaround was to modify the program source so that it set a return value. (These two functions would have been type void in C).

So in the example above

TOCMPLX= 0

as the first command in the fortran would allow the Function TOCMPLX to compile (but maybe not to work correctly).
