1 Compilation

package: cext-lib

procedure
(compile-extension quiet?
input-file
output-file
include-dirs) → any/c
  quiet? : any/c
  input-file : path-string?
  output-file : path-string?
  include-dirs : (listof path-string?)

Compiles the given input file (C source) to the given output file (a compiled-object file). The quiet? argument indicates whether command should be echoed to the current output port. The include-dirs argument is a list of directories to search for include files; the Racket installation’s "include" directories are added automatically.

1.1 Compilation Parameters

parameter
(current-extension-compiler) → (or/c path-string? false/c)
(current-extension-compiler compiler) → void?
compiler : (or/c path-string? false/c)

A parameter that determines the executable for the compiler.

The default is set by searching for an executable using the PATH environment variable, or using the CC or MZSCHEME_DYNEXT_COMPILER environment variable if either is defined (and the latter takes precedence). On Windows, the search looks for "cl.exe", then "gcc.exe", then "bcc32.exe" (Borland). On Unix, it looks for "gcc", then "cc". A #f value indicates that no compiler could be found.

parameter
(current-extension-compiler-flags)
→
(listof (or/c path-string?
              (-> (or/c null? (listof string?)))))
(current-extension-compiler-flags flags) → void?
   flags :
(listof (or/c path-string?
              (-> (or/c null? (listof string?)))))

A parameter that determines strings passed to the compiler as flags. See also expand-for-compile-variant.

On Windows, the default is (list "/c" "/O2" "/MT" 3m-flag-thunk) for "cl.exe", or (list "-c" "-O2" "-fPIC" 3m-flag-thunk) for "gcc.exe" and "bcc32.exe", where 3m-flag-thunk returns (list "-DMZ_PRECISE_GC") for the 3m variant and null for the CGC variant. On Unix, the default is usually (list "-c" "-O2" "-fPIC" 3m-flag-thunk). If the CFLAGS or MZSCHEME_DYNEXT_COMPILER_FLAGS environment variable is defined (the latter takes precedence), then its value is parsed as a list of strings that is appended before the defaults.

parameter
(current-make-compile-include-strings)
→ (-> path-string? (listof string?))
(current-make-compile-include-strings proc) → void?
proc : (-> path-string? (listof string?))

A parameter the processes include-path inputs to the compiler; the parameter values takes an include directory path and returns a list of strings for the command line.

On Windows, the default converts "dir" to (list "/Idir") for "cl.exe", (list "-Idir") for "gcc.exe" and "bcc32.exe". On Unix, the default converts "dir" to (list "-Idir"). If the CFLAGS environment variable is defined, then its value is parsed as a list of flags that is appended before the defaults.

parameter
(current-make-compile-input-strings)
→ (-> (or/c string? path?) (listof string?))
(current-make-compile-input-strings proc) → void?
proc : (-> (or/c string? path?) (listof string?))

A parameter that processes inputs to the compiler; the parameter’s values takes an input file path and returns a list of strings for the command line. The default is list.

parameter
(current-make-compile-output-strings)
→ (-> (or/c string? path?) (listof string?))
(current-make-compile-output-strings proc) → void?
proc : (-> (or/c string? path?) (listof string?))

A parameter that processes outputs specified for the compiler; the parameter’s value takes an output file path and returns a list of strings for the command line.

On Windows, the default converts "file" to (list "/Fofile") for "cl.exe", or to (list "-o" "file") for "gcc.exe" and "bcc32.exe". On Unix, the default converts "file" to (list "-o" "file").

parameter
(current-extension-preprocess-flags)
→ (listof (or/c string? path? (-> (or/c string? path?))))
(current-extension-preprocess-flags flags) → void?
flags : (listof (or/c string? path? (-> (or/c string? path?))))

A parameters that specifies flags to the compiler preprocessor, instead of to the compiler proper; use these flags for preprocessing instead of current-extension-compiler-flags.

The defaults are similar to current-extension-compiler-flags, but with "/E" (Windows "cl.exe") or "-E" and without non-"-D" flags.

parameter
(compile-variant) → (one-of/c 'normal 'cgc '3m)
(compile-variant variant-symbol) → void?
variant-symbol : (one-of/c 'normal 'cgc '3m)

A parameter that indicates the target for compilation, where 'normal is an alias for the result of (system-type 'gc)

1.2 Helper functions

procedure
(use-standard-compiler name) → any
name : (apply one-of/c (get-standard-compilers))

Sets the parameters described in Compilation Parameters for a particular known compiler. The acceptable names are platforms-specific:

Unix: 'cc or 'gcc
Windows: 'gcc, 'msvc, or 'borland
MacOS: 'cw

procedure
(get-standard-compilers) → (listof symbol?)

Returns a list of standard compiler names for the current platform. See use-standard-compiler.

procedure
(expand-for-compile-variant l) → any
l : (listof (or/c path-string? (-> (listof string?))))

Takes a list of paths and thunks and returns a list of strings. Each thunk in the input list is applied to get a list of strings that is inlined in the corresponding position in the output list. This expansion enables occasional parametrization of flag lists, etc., depending on the current compile variant.

1.3 Signature

(require dynext/compile-sig)

package: cext-lib

signature
dynext:compile^ : signature

Includes everything exported by the dynext/compile module.

1.4 Unit

(require dynext/compile-unit)

package: cext-lib

value
dynext:compile@ : unit?

Imports nothing, exports dynext:compile^.
