6 Evaluation
This library provides utilities for building and runnign C programs with a system-installed C compiler. Currently the only supported compiler is GCC.

6.1 External Processes
struct
(struct exn:fail:process exn:fail (out error-out) #:extra-constructor-name make-exn:fail:process) out : input-port? error-out : input-port?
Raised when a system error occurs in executing an external process.
6.2 GCC
parameter
(current-gcc) → (or/c path? #f)
(current-gcc gcc) → void? gcc : (or/c path? #f)
The path to the GCC executable.
By default, this is initialized to:
(or (find-executable-path "gcc") (find-executable-path "gcc.exe"))
procedure
(gcc print-source) →
input-port? input-port? print-source : (-> any)
Runs a C program with GCC, using the value of current-gcc to find the GCC executable.
The program source is obtained by invoking print-source, which is run in a continuation
barrier to prevent re-entrant evaluation. The external program is built to a temporary file which
is automatically deleted after the program terminates.
The external program is run in a separate thread, so this procedure returns before the program necessarily terminates. The procedure produces two values, input ports for reading from the external program’s stdout and stderr ports.
