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.
