#! /bin/sh

# NOTE: you may need to adjust the references to /usr/local/... below
#	(or remove them if they're not needed on your system).
#	You may need to add something like "-Olimit 2000" to the -O
#	processing below or change it to something more suitable for your
#	system.  See also the comments starting with ### below.

#	Note that with some shells, invocations of the form
#		CFLAGS='system-specific stuff' fc ...
#	may be useful as way to pass system-specific stuff to the C compiler.
#	The script below simply appends to the initial CFLAGS value.

# f77-style shell script to compile and load fortran, C, and assembly codes

#	usage:	f77 [options] files [-l library]

#	Options:

#		-o objfile	Override default executable name a.out.

#		-a		use automatic variable storage (on the stack)
#				by default -- rather than static storage

#		-c		Do not call linker, leave relocatables in *.o.

#		-C		Check that subscripts are in bounds.

#		-S		leave assembler output on file.s

#		-L libdir	(passed to ld)

#		-l library	(passed to ld)

#		-u		complain about undeclared variables

#		-w		omit all warning messages

#		-w66		omit Fortran 66 compatibility warning messages

#		files		FORTRAN source files ending in .f .
#				FORTRAN with cpp preprocessor directives
#					ending in .F .
#				C source files ending in .c .
#				Assembly language files ending in .s .
#				efl source files ending in .e .
#				RATFOR files ending in .r .
#				Object files ending in .o .
#				Shared libraries ending in .so .

#				f2c prototype files ending in .P ; such
#				files only affect subsequent files.

#		-D def		passed to C compiler (for .c files)
#				or to cpp (for .F files)

#		-I includepath	passed to C compiler (for .c files)
#				or to cpp (for .F files), and to f2c

#		-m xxx		passed to C compiler as -mxxx

#		-N tnnn		allow nnn entries in table t

#		-P		emit .P files

#		-r8		promote real to double precision and
#				complex to double complex

#		-s		strip executable

#		-trapuv		Initialize floating-point variables to
#				signaling NaNs (on machines with IEEE
#				arithmetic) unless they appear in save,
#				common, or data statements.  Initialize
#				other kinds of variables to values that
#				may attract attention if used without
#				being assigned proper values.

#		-U def		passed to C compiler (for .c files)
#				or to cpp (for .F files) to remove def
#		-v		show current f2c version
#		--version	same as -v
