cim

NAME

cim - Compile Simula programs into C

SYNOPSIS

cim [ options ] file ...

DESCRIPTION

GNU Cim is the Simula compiler that compiles into C. The C program will then be compiled with cc , and linked with other modules.

GNU Cim will accept one Simula program and other none Simula modules. The specified Simula program will be compiled and linked with the modules. If a main Simula program is compiled then it will be automatic linked with the Simula modules that it uses. If a separate Class or Procedure is compiled, then the linking will be supressed.

OPTIONS

The following options are accepted by the cim command:

-a

Try to produce an atr-file even if an error occurs. Compare the produced atr-file with the atr-file produced from previous compilation and if they differ return an error status code. With use of this option it is possible to have external modules with circular dependencies. You will then need to compile all the modules with this option until no error status codes are returned. Then you should do a final compilation with option -p or option -d. To get this to work it is important that the topmost external head does not contain any external declaration that is part of the circular dependency. Such external declarations must be placed in an external head that comes after the first class- or procedure decraration.

-b

The following argument will be parsed to the CC-command.

-B

The following argument will be parsed to the link-command.

-c

Supress linking of the complete program.

-Cname

Set the name of the C compiler.

-d

Compare the produced c-code with the code produced from previous compilation and if they are equal then touch the object-file instead of compiling the c-code.

-Dname

Define a symbol name.

-e

On systems that support dynamic linking, this prevents linking with the shared libraries. On other systems, this option has no effect.

-E

Run only the preprocessor and output the result to standard output.

-g

Make the C compiler produce debugging information. This option is useful for debugging the generated code.

-G

Invoke the Gnu Project C compiler instead of the standard C compiler. This option is useful if the standard C compiler don't generate correct code.

-h

Print a summary of the options to `cim', and exit.

-H

Omit line number information in the compiled program. This will make the program smaller and faster.

-I dir

Use the Simula include file located in directory dir instead of the standard directory.

-llibrary

Link with object library library. This option is parsed to the link-command.

-L dir

Use the Simula library located in directory dir instead of the standard directory.

-m

The memory pool size may be set at runtime by an option -mn.

-mn

Set the initial memory pool size to n mega bytes.

-Mn

Set the maximal memory pool size to n mega bytes.

-N

Only link the specifiede files.

-o

The following argument is the name of the output executable file.

-p

If supported for the target machines, generate position-independent code, suitable for use in a shared library.

-P

Only link the specifiede files.

-q

Run the compiler in quiet mode.

-s

Only C-compile and link the specified files.

-S

Run the source file trough Simula-compiler, only.

-R

Recompile the module using the same timestamp.

-t

Do not remove temporary files. If a main program is compiled with option -r, then the executable file will be removed unless this option or option -T is specified.

-Uname

Remove any initial definition of the symbol name (Inverse of the -D option).

-v

Run the compiler in verbose mode.

-V

Print the version number of Cim and exit.

-w

Do not print warnings.

FILES

file

Executable file.

file.a

Library of source files, attribute files and object files. Include this simula library when compiling and linking. The simula library is created with ar(1V) and ranlib(1). All source and .atr files should be placed before .o files in the archive.

file.o

Object file.

file.c

Simula-compiler output file.

file.h

Output file that is included in file.c.

file.sim

Simula source file.

file

File names without an extension are assumed to be shorthand notation for the corresponding .sim file.

/usr/local/lib/libcim.a

Simula library that contains the environment, Run Time System and class Simset and Simulation. The source code to Simset and Simulation is also included, so these parts can be compiled using compiler directive %include.

/usr/local/include/cim.h

Include file for the produced C-code.

DIAGNOSTICS

The diagnostics produced by the Simula compiler are intended to be self-explanatory.
