Installation:
|
||||
|
||||
You will need to download qemu and set up a virtual machine containing a compiler.
|
||||
|
||||
Then you will need to edit some of the following files and replace IP addresses
|
||||
and paths where appropriate (some locations may not yet be documented).
|
||||
|
||||
Once the files have been configured and copied to the appropriate locations,
|
||||
you will need to first start up the compiler_vm_server.pl script, and then
|
||||
connect to qemu's monitor and issue the 'savevm 1' command to save the virtual
|
||||
machine in this state. Between compiles, this state will be loaded via
|
||||
'loadvm 1' in order to reset everything within the machine for a clean and working
|
||||
environment for subsequent compiles.
|
||||
|
||||
Files:
|
||||
|
||||
(Read within each file for configuration instructions.)
|
||||
|
||||
- compiler_client.pl: Main entry point for compiling snippets. Sends over TCP to
|
||||
compiler_server.pl. This file can be run be run from the
|
||||
client machine or anywhere.
|
||||
|
||||
- compiler_server.pl: Responsible for setting up a TCP server to listen for
|
||||
incoming compile requests; and launching and resetting
|
||||
the virtual machine. Sends to compiler_vm_client.pl.
|
||||
Run this file on the server hosting the virtual machine.
|
||||
|
||||
- compiler_vm_client.pl: Responsible for sending snippets to the virtual
|
||||
machine. Also expands/translates and formats
|
||||
snippets into compilable code (with main function and
|
||||
headers), and handles "interactive-editing".
|
||||
Sends over TCP to qemu serial port, waits for result,
|
||||
then sends result back caller (compiler_server.pl).
|
||||
Run this file on the server hosting the virtual machine.
|
||||
|
||||
- compiler_vm_server.pl: Runs on the system inside the virtual machine.
|
||||
This script listens for incoming code snippets over
|
||||
the virtual machine's serial port.
|
||||
Calls compiler_watchdog.pl to monitor its exit signal
|
||||
or exit status, then returns result back over serial
|
||||
port (to compiler_vm_client.pl).
|
||||
|
||||
- compiler_watchdog.pl: Runs a program and watches its exit signals/status.
|
||||
|
||||
*** The following files are just auxiliary tools to start/connect to qemu, provided
|
||||
for convenience only. Perhaps they will be useful during installation/testing:
|
||||
|
||||
- monitor: Connects to qemu monitor (internal console) over TCP.
|
||||
|
||||
- serial: Connects to qemu serial port over TCP.
|
||||
|
||||
- runqemu: Launches qemu with a visible window, but without networking support.
|
||||
|
||||
- runeqmu.net: Launches qemu with a visible window, and with networking support.
|
||||
You may load a state previously saved with runqemu and reboot it
|
||||
or otherwise reload its networking configuration to gain networking.
