I am trying to compile a program for my assignment at school that uses curses.I have installed libncurses5-dev, and curses.h is now in /usr/include, but I am getting all these errors(it compiles fine at school).
Code:
grcunning@grcunning-desktop:~/school/cs474/assign7$ gcc -o proj7 proj7.c
/tmp/cc2ZFXrs.o: In function `main':
[code]....
When I getch() a key event (UP arrow key), the getch() function return a string of characters that I cannot compare with curses.KEY_UP constant. Here is the code I use :
while True:
w = gb.scrn.getch()
c = chr(w)
otp = 'touche:'+str(w)+' '+str(c)+"
[Code]...
It seems like getch() return three distincts bytes while I would retrieve it with a single ord() instruction in python like describes in curses/python documentation.
I have a Database using C programming and text based screen using curses. When I run the program and select "add a customer". The startcontract and endcontract variable does not appear. Also, when I add a name, it does not display what I have written down. All that appears is some jargon which I don't know how to fix it.

I am running Valgrind on my program. It shows me two errors but mentions only addresses against them and not actual code even on a debug build.

i have installed suse 11.3 and c and c++ programs are running fine but when i try to execute any code with curses.h header included error is shown that curses.h not found what can i do?

I've been messing a fair bit with some of my own scripts, and in some cases, getting sent an IM would be useful to let me know when a task is done. the ability to set account information in a text file.It'd be okay if I can designate only a single recipient, or set recipients in the config file at the very least, jabber support.Be able to be controlled via standard shell commands - for example I should be able to pipe a message output into the program for example.

When I run wicd-curses from the cli, it finds the network and I'm able to obtain an IP address. The wireless ESSID that I'm connecting to is encrypted with WPA. I can't seem to figure out how to input the encryption password so I can connect.

I've generated some srt subtitle files using gocr from pgm files used in DVD's. The ocr program gets confused between lower case L and upper case i and sees them as the same thing. This results in words with capital i's in them instead of lower case L.
What is the best way to automate the correction without a spell checker? I tried sed, but it's difficult to tell between the i's that you want and those that need changing. I figured that any word that consists solely of capital i's is ok, e.g. Roman Numerals, but any capital i not at the beginning of a word needs changing.

I am reading Sams Teach Yourself SQL in one hour a day. In this book they work with both Oracle and MySQL to teach you SQL. So I installed mysql on my box and I am creating the empty database they use in this book so I can follow along as I read. I have noticed a few typos in the book and now I have noticed some code errors too. I just don't know enough to fix em. I am working on creating the empty database and I am getting syntax errors when I create certain tables. I have checked both the printed version of the book and the electronic version (which differ slightly) and both give me the same synatax errors. First is Creating the first table of the database. Here is the code given to me to enter. The Electronic version

The 2010 CWE/SANS Top 25 Most Dangerous Programming Errors is a list of the most widespread and critical programming errors that can lead to serious software vulnerabilities. They are often easy to find, and easy to exploit. They are dangerous because they will frequently allow attackers to completely take over the software, steal data, or prevent the software from working at all.
The Top 25 list is a tool for education and awareness to help programmers to prevent the kinds of vulnerabilities that plague the software industry, by identifying and avoiding all-too-common mistakes that occur before software is even shipped. Software customers can use the same list to help them to ask for more secure software. Researchers in software security can use the Top 25 to focus on a narrow but important subset of all known security weaknesses. Finally, software managers and CIOs can use the Top 25 list as a measuring stick of progress in their efforts to secure their software.
I have a script that that is supposed to send me an e-mail when a host is not responding to ping:

I am trying to modify the source code of a C application (quagga) in order to insert data into a mysql table. I have added 2 new source files to the source (neto_mysql, neto_trend) which in turn use mysql.h. I have also modified the Makefile.am file to include the /usr/include/mysql directory.
When trying to compile, i get the following error. What am I missing? I have minimal experience with formal C applications like this. I feel like I may also have to include the mysql.h file in the libbgp? I dont understand why it cant find the mysql functions...

View 1 Replies View RelatedFirst off, I'm completely new to bash scripting so forgive me if I make any egregious errors. I'm trying to make pop-up reminders for the simple calendar program when. This is what I have so far:
Code:
#!/bin/bash
# set the time format for when
#current="$(date +%I:%M %p)"
current="$(date +%-l%p)"
today=~/.when/today
[Code]....
When I run the script, gxmessage pops up and displays the correct information, but it does so for each line in "~/.when/today" that contains a time that matches the current system time (which would be three pop-ups at 10PM, according to the example). I want it to display the information only once. How can this be accomplished? Is a while loop even the right job for this?
Created application is working too slow, looks like there are a lot of memory leaks, there are a lot of pointers. Any effective tool for run-time errors and memory leaks detection in Visual Studio C++?
