This library provides utilities for building and runnign C programs with
a system-installed C compiler. Currently the only supported compiler is
6.1 External Processes
Raised when a system error occurs in executing an external process.
The path to the GCC executable.
By default, this is initialized to:
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.
