Usage

Overview

csc is a program that invokes the CHICKEN compiler and the host systems C compiler to generate an executable from a Scheme source file or C files generated by CHICKEN.

FILENAME is a Scheme source file name with optional extension or a C/C++/Objective-C source, object or library file name with extension. OPTION may be one of the following:

-epilogue FILENAME

-dll, -library

Compile multiple units into a dynamic library.

-libdir DIRECTORY

Override location of runtime library directory.

Options to other passes:

-C OPTION

Pass option to C compiler.

-L OPTION

Pass option to linker.

-L<DIR>

Pass “-L<DIR>” to linker (add library path).

-k

Keep intermediate files.

-c

Stop after compilation to object files.

-t

Stop after translation to C.

-cc COMPILER

Select a C compiler other than the default.

-cxx COMPILER

Select a C++ compiler other than the default.

-ld COMPILER

Select a linker other than the default.

-static

Link with static CHICKEN libraries and extensions.

-F<DIR>

Pass “-F<DIR>” to C compiler (add framework header path on Mac OS X).

-rpath PATHNAME

Add directory to runtime library search path.

-Wl,...

Pass linker options.

-strip

Strip resulting binary.

Inquiry options:

-home

Show home-directory (where support files go).

-cflags

Obscure options:

-debug MODES

-compiler PATHNAME

Use a compiler other than the default ‘chicken’.

-raw

Do not generate implicit init- and exit code.

-emit-external-prototypes-first

Emit prototypes for callbacks before foreign declarations.

-regenerate-import-libraries

Always emit import libraries, even when their contents haven't changed. The default behaviour is to preserve existing import libraries.

-ignore-repository

Do not refer to repository for extensions.

-keep-shadowed-macros

Do not remove shadowed macros.

-host

Compile for host when configured for cross-compiling.

-private-repository

Load extensions from executable path.

-deployed

Link support file to be used from a deployed executable (sets ‘rpath’ accordingly, if supported on this platform.)

-no-elevation

Embed manifest on Windows to supress elevation warnings for programs named ‘install’ or ‘setup’.

Options can be collapsed if unambiguous, so “-vkfO” is the same as “-v -k -fixnum-arithmetic -optimize”.

Environment

The following environment variables change the behaviour of csc:

CSC_OPTIONS

Can hold default options that should be passed to every invocation of csc.

Exit status

The csc utility exits 0 on success, and >0 if an error occurs.
