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 outfile] [-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 Fortran, 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 preprocessor. 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 compatibility.

C'est très bien, mais les codes pour Antibug et pour
MultiDeskOS ne sont pas 52 et 70. Ils ont une valeur
de plusieurs millions. Toutefois, même si le code est
un longint, le fait d'avoir utiliser des + dans l'algo remet
finalement le code en 256 avec dépassement.
259 vaut donc 3. C'est pour cela que tu obtiens les
nombre 52 et 70.
