Hello,
I am still trying to adjust an sgi-fortran-code to linux g77. I get this error-message:
main.o(.text+0x10c3): In function `MAIN__': : undefined reference to `save_vel__' main.o(.text+0x10d2): In function `MAIN__': : undefined reference to `save_pres__' collect2: ld returned 1 exit status make: *** [calc_les_03_cube] Error 1
Without the two subroutines 'save_vel.f''save_pres.f' the program works well.
Did you compile save_vel.f and save_pres.f with g77 as well ?
Note that g77 appends two underscores to the name of a subroutine that contains an underscore.
If you just assume the loader will get save_vel and save_pres from a library compiled with another compiler that doesn't append the extra underscore, you're out of luck.
Anyways, don't assume g77-compiled code and code compiled with another compiler on your SGI machine will work together flawlessly, even if the loader phase succeeds ...
Hope this helps,
