Running UNIX fortran compilers
24 Jan 1994
The fortran compilers on different UNIX platforms have different options for
controlling debugging and otptimization. It order to simplify the compiling of
code on different computers, a shell script can be used to issue the
Such a script was written for GEM and then adapted by the SLAC B factory
group. This script knows how to call compilers on AIX, HP-UX, IRIX, SunOS,
Solaris, ULTRIX, and OSF1. For example it knows that the fortran compiler
under AIX is called xlf not f77.
It also calls the C preprocessor to handle the includes. Unlike when the
compiler calls the C preprocessor itself, the expanded code is kept. This
expanded code from name.F is kept in name.f, and name.f is then compiled. This
technique makes debugging easier, since the source code line number are
correct in the debugger.
We keep our script in a /usr/products/IRIX/off781/devel/bin/f77_781.
Alternatively, if you have setup off781 you can use $OFF781_BIN/f77_781.
