Oct 29, 2009 IRC Meeting with Fardad - Questions

For today's meeting I hope to clarify the file hierarchy for assignment 2. Specifically, I am a little confused about #includes, and how linking will occur with all the .cpp and .h classes separated in they're own folders.

I also have questions about what state the .cpp and .h files should be in. Many of the descriptions for assignment 2 classes listed on the wiki are incomplete, or no description at all.

My mind will be at ease once I am sure all the files are placed where they should be, and we get a proper build.

SVN discussion and summary

Our first meeting with Fardad about the OOP344 Assignment 2 was on Tuesday October 27, 2009 at 17:00. Our team experienced a few problems with SVN. A summary, and an edited transcription can be found at the following link...

c validate input/trailing characters

/* A simple program to demonstrate

OOP344 assignment 1 - To compile on mac

This entire post can be copy/pasted into your ciol.h between
# if PLATFORM == PLT_LNX
and
# elif PLATFORM == PLT_BCC || PLATFORM == PLT_VCC



Notes are included in the commented-out area. Code starts here...

# elif PLATFORM == PLT_MAC
/*

To compile on mac:

Adding the line
#define NULL 0
fixed an error on mac that said
"NULL not defined"

be sure to #include inside ciol.c
eg.
# if PLATFORM == PLT_LNX
#include

# elif PLATFORM == PLT_MAC
#include

The message that I used to compile:
gcc as1tester.c ciol.c -lcurses

I got the following warnings when I compiled, but it still works.

ciol.c: In function ‘io_edit’:
ciol.c:185: warning: incompatible implicit declaration of built-in function ‘malloc’
ciol.c: In function ‘io_displayMenuItem’:

There are some strange looking characters in some of the strings
output by main. I will be investigating it.

The macbook pro does not have all the dedicated keys that
a full keyboard would have. I made a substitute key mapping
using modifier keys like [shift] and [option]. A chart, and
the key_codes are listed below.

Some useful PLT_MAC key combinations:
F1_KEY = [option] + [F1]
F2_KEY = [option] + [F2]
F3_KEY = [option] + [F3]
F4_KEY = [option] + [F4]
F5_KEY = [option] + [F5]
F6_KEY = [option] + [F6]
F7_KEY = [option] + [F7]
F8_KEY = [option] + [F8]
F9_KEY = [option] + [F9]
F10_KEY = [option] + [F10]
F11_KEY = [option] + [F11]
F12_KEY = [option] + [F12]
INSERT_KEY = [shift] + [option] + [I]
HOME_KEY = [shift] + [option] + [H]
END_KEY = [shift] + [option] + [E]
PGUP_KEY = [shift] + [option] + [U]
PGDN_KEY = [shift] + [option] + [D]
BS_KEY = [delete]
DEL_KEY = [fn] + [delete]
