NAME

       fort77 - invoke f2c Fortran translator transparently, like a compiler

SYNOPSIS

       fort77  [-c]  [-g]  [-v] [-k] [-P] [-cpp] [f2c option ...]  [-L directory ...]  [gcc-option ...]  [link option ...]  [-O optlevel] [-o out-
       file] [-s] [-w] [-Wx,arg1[,arg2]...]  file ...

DESCRIPTION

       The fort77 script invokes the f2c command transparently, so it can be used like a real Fortran compiler.  It can be used  to  compile  For-
       tran, C and assembler code, and to link it with the f2c libraries.

       File  arguments	ending	with .f are compiled as Fortran source files.  Files which end with .P are passed through to f2c, and files ending
       with .F are passed to the C preprocessor (invoked as "/lib/cpp -traditional") first.  Any switches passed via -D will be passed to the pre-
       processor.  If the translation is successful, the resulting C files will be passed to cc for translation into an object file.  Files ending
       in .c, .C, .cc, .i, .s, .S, .m, .cc or .cxx are passed to the GNU C compiler directly; see gcc(1).  All	other  files  are  passed  to  the
       linker.

OPTIONS

       -c      Supress linking and produce an object ( .o ) file from each source file.

       -g      Include debugging information.  -v Be verbose; supplying this twice will also tell the C compilers etc to be verbose.

       -k      Keep the C files generated by f2c around.

       -cpp    Pass Fortran code through the C preprocessor, as if filenames ended in .F.

       -P      Generate f2c .P files.

       -Ldirectory
	       Include directory in the search for libraries in the final linking stage.

       -o outfile
	       Send output to outfile.

       -trapuv Have f2c generate code to trap uninitialized values.

       -Wx,arg1[,arg2...]
	       Pass  the  argument[s]  argi through to the subprocess x, where x can assume one of the following values: f for the f2c step, p for
	       the preprocessing step, c for the C compiler, a for the assembler (this is actually passed to the C compiler, too), and l  for  the
	       linker.	 As  an  example, defining a preprocessor constant for the C compilation step would be done with -Wc,-DUNIX=1.	Specifying
	       the -f option to f2c would be done via -Wf,-f.

       f2c option
	       fort77 passes through almost all f2c options: -C, -U, -u, -a, -E, -h, -P, -R, -r, -z, -I2, -I4, -onetrip, -!c, -!l, -!P, -!R, -ext,
	       -!bs, -W[n], -trapuv, -w8, -r8 and -w66.

       gcc options
	       The following options are passed through to gcc: -f*, -W*, -U*, -A*, -m*, -S, -E, -v, -x, -pipe, -o, -I, -V, -b*, -p, -pg.

       linker option
	       The options passed to the linking stage are -static, -shared, -v, -V, and -symbolic.

BUGS

       To make debugging work, you need to set a breakpoint at MAIN__ before you start.

       f2c This script automatically supplies the -I.  option to f2c.  Older versions of f2c may not support this.

       This script is for the interaction of gcc and f2c; using it with another compiler will probably require modification.

       The fort77 script does not strictly conform to Posix.2, because it acceppts long options with one leading slash.  This is done for gcc com-
       patibility.
