NAME

csc — driver program for the CHICKEN Scheme compiler

SYNOPSIS

csc [OPTION ...] [FILENAME ...]

DESCRIPTION

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:

General options:

-h, -help: Display usage text and exit.
-v, -verbose: Show compiler notes and tool-invocations.
-vv: Display information about translation progress.
-vvv: Display information about all compilation stages.
-version: Display Scheme compiler version and exit.
-release: Display release number and exit.

File and pathname options:

-o FILENAME, -output-file FILENAME: Specifies target executable name.
-I PATHNAME, -include-path PATHNAME: Specifies alternative path for included files.
-to-stdout: Write compiler to stdout (implies -t).
-s, -shared, -dynamic: Generate dynamically loadable shared object file.

Language options:

-D SYMBOL, -feature SYMBOL: Register feature identifier.
-no-feature SYMBOL: Disable builtin feature identifier.
-c++: Compile via a C++ source file (.cpp).
-objc: Compile via Objective-C source file (.m).

Syntax related options:

-i, -case-insensitive: Don't preserve case of read symbols.
-K, -keyword-style STYLE: Enable alternative keyword-syntax (prefix, suffix or none).
-no-parentheses-synonyms: Disables list delimiter synonyms.
-no-symbol-escape: Disables support for escaped symbols.
-r5rs-syntax: Disables the CHICKEN extensions to R5RS syntax.
-compile-syntax: Macros are made available at run-time.
-j MODULE, -emit-import-library MODULE: Write compile-time module information into separate file.
-J, -emit-all-import-libraries: Emit import-libraries for all defined modules.
-no-compiler-syntax: Disable expansion of compiler-macros.
-m NAME, -module NAME: Wrap compiled code in module of the given name.
-M, -module-registration: Always generate module registration code, even when import libraries are emitted.
-N, -no-module-registration: Do not generate module registration code. Overrides -module-registration.

Translation options:

-x, -explicit-use: Do not use units ‘library’ and ‘eval’ by default.
-P, -check-syntax: Stop compilation after macro-expansion.
-A, -analyze-only: Stop compilation after first analysis pass.

Debugging options:

-w, -no-warnings: Disable warnings.
-d0, -d1, -d2, -d3, -debug-level NUMBER: Set level of available debugging information.
-no-trace: Disable rudimentary debugging information.
-profile: Executable emits profiling information.
-accumulate-profile: Executable emits profiling information in append mode.
-profile-name FILENAME: Name of the generated profile information file.
-types FILENAME: Load additional type database.

Optimization options:

-O, -O0, -O1, -O2, -O3, -O4, -O5, -optimize-level NUMBER: Enable certain sets of optimization options.
-optimize-leaf-routines: Enable leaf routine optimization.
-no-usual-integrations: Standard procedures may be redefined.
-u, -unsafe: Disable safety checks.
-local: Assume globals are only modified in current file.
-b, -block: Enable block-compilation.
-disable-interrupts: Disable interrupts in compiled code.
-f, -fixnum-arithmetic: Assume all numbers are fixnums.
-disable-stack-overflow-checks: Disables detection of stack-overflows.
-inline: Enable inlining.
-inline-limit LIMIT: Set inlining threshold.
-inline-global: Enable cross-module inlining.
-specialize: Perform type-based specialization of primitive calls.
-oi FILENAME, -emit-inline-file FILENAME: Generate file with globally inlinable procedures (implies -inline -local).
-consult-inline-file FILENAME: Explicitly load inline file.
-ot FILENAME, -emit-types-file FILENAME: Write type-declaration information into file.
-no-argc-checks: Disable argument count checks.
-no-bound-checks: Disable bound variable checks.
-no-procedure-checks: Disable procedure call checks.
-no-procedure-checks-for-usual-bindings: Disable procedure call checks only for usual bindings.
-no-procedure-checks-for-toplevel-bindings: Disable procedure call checks for toplevel bindings.
-strict-types: Assume variable do not change their type.
-clustering: Combine groups of local procedures into dispatch loop.
-lfa2: Perform additional lightweight flow-analysis pass.
-unroll-limit LIMIT: Specifies inlining limit for self-recursive calls.

Configuration options:

-unit NAME: Compile file as a library unit.
-uses NAME: Declare library unit as used.
-heap-size NUMBER: Specifies heap-size of compiled executable.
-nursery NUMBER -stack-size NUMBER: Specifies nursery size of compiled executable.
-X FILENAME, -extend FILENAME: Load file before compilation commences.
-prelude EXPRESSION: Add expression to beginning of source file.
-postlude EXPRESSION: Add expression to end of source file.
-prologue FILENAME: Include file before main source file.
-epilogue FILENAME: Include file after main source file.
-e, -embedded: Compile as embedded (don't generate ‘main()’).
-gui: Compile as GUI application.
-link NAME: Link extension with compiled executable (implies ‘-uses’).
-R NAME, -require-extension NAME: Require extension and import in compiled code.
-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.
-I<DIR>: Pass “-I<DIR>” to C compiler (add include path).
-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).
-framework NAME: Passed to linker 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: Show required C-compiler flags and exit.
-ldflags: Show required linker flags and exit.
-libs: Show required libraries and exit.
-cc-name: Show name of default C compiler used.
-cxx-name: Show name of default C++ compiler used.
-ld-name: Show name of default linker used.
-dry-run: Just show commands executed, don't run them (implies ‘-v’).

Obscure options:

-debug MODES: Display debugging output for the given 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.
