i have this warning "differ in signedness".
[Code]...
so i was getting this error. im thinking it may be because of somewhere i declared unsigned and signed so this signedness warning occurring.
Code:
switcase.c: In function ImplementDebugCmd: switcase.c:385: warning: pointer targets in passing argument 1 of STRING_stricmp differ in signedness
I want to use vfprintf with the char * on 64-bit. Here is the sample code:

In this code, I am getting warning: passing argument 3 of vfprintf from incompatible pointer type I have done sizeof(va_list) on 64-bit, and its 24 bytes. I don't know how am I suppose to use the va_list this way.
I'm trying to install a program (MOPAC2007) from the source code which is a 32-bit program, but I get the following errors:

I am trying to simulate a shell. So what I do is checking of having the parameters from standard input, suc as "/bin/ls -l /home/france/Documents", and then passing them to function execute, which at some point calls execvp(argv[0],argv)The problem is that I don't succeed in using these arguments, while if I call execvp(paramList[0],paramList) it works!!!! Where paramList is exactly what I would put on standard input, but defined statically.
Code:
#include<unistd.h>
#include<stdio.h>

Say, i have an imaginary std library function, which I want to call.
Code:
void std_lib_func(ObjectType *param);
Now in my c++ program, I have a main() function, and I will like to call a customized function (which will in turn call the std lib function) from the main function, as below:
Code:
int main()
{
ObjectType *aobj;
customized_func(aobj);
}
[Code]...
I tried the below but get an error that the std lib function is expecting a ObjectType* param, not aobj. How should I work this out.
Code:
void customized_func(ObjectType aobj)
I have a number of projects, say test1, test2, test3,. I want to make and install all of them in exactly the same way; so I would like to say
make test2
make install test2
with the same Makefile.
In other words, I would like to pass the argument test2 (or just 2) to the Makefile, so this is taken as the target for make or make install. This must be a common wish; but I don't see any appropriate option with "man make" on my Fedora-12 system.

I'm trying to write a base script which will divide an argument by 10 and then use that argument in another program. Since my argument can be a floating point number, I used bc to accomplish this. Here's an example of a simplified version of what I have so far:

#make sure the first argument was formatted correctly

I'm trying to work out the best way to achieve the following.
1)php page that grabs data from a local database. (not a problem)
2)It then needs to send this data to a c program/service running on a remote server. (I probably need it to be able to handle 4+ million reocrds in an array)
3) The c service then needs to process the data and send it back to the initial php script that called it. i was hoping this could be in a an array like structure of some kind. 4)update the db with the results.
I was thinking of using gsoap to write a simple c soap service that php can communicate with. Would this be the right way of doing this or would something like sockets in php be a better way of sending this volume of data as an array or struct to linux c socket if thats even possible.
i'm programming a small tcp client, but i need that the server knows the source ip. My client receives a external connection and forwards, but the ip seen by the server, of course, is the client ip. I would like, change this ip to original source ip.
I don't know how to do this. I tried with the connect and select function.
I have a file with around 1000 IP addresses in it and I need to be able to ssh into each one of them, run a single command, and then exit. I already know the ssh command I want to run and it looks like this:
Code:
shpass -p [password] ssh -p 10022 -o StrictHostKeyChecking=no root@[ip variable] 'reboot'
(I know shpass is not good to use and keys are the correct way but I don't have any other options in this scenario.) if these ip addresses were in a .csv file, by themselves with no other information, how would I create a script to do the above command to each ip until the end of the file?
If I have the following links in HTML
Code:
<a href=lang.php?lang=cymraeg>Cymraeg</a>
<a href=lang.php?lang=english>English</a>

I cannot for the life of me get this little (simple) script I wrote to work. Here is the entire script:
Code:
#!/bin/bash
ASPECT=`mediainfo $1 |grep "Display aspect ratio" |cut -d : -f 2`
HEIGHT=`echo "320 / $ASPECT" |bc`
SIZE=`echo 320x$HEIGHT`
[code]......
An input filename ($1) is fed into mediainfo, which by the use of grep and cut spits out a single number which is the aspect ratio. This is then divided by bc into 320, which gives the desired height dimension for the file that I want ffmpeg to create for me. Finally, ffmpeg runs using the calculated dimensions... Basically, it's the passing of the $ASPECT variable to bc that seems to fail. It looks like bc won't read the output from the mediainfo line... It always crashes out with:
Code:
(standard_in) 1: illegal character: ^M I've tried doing something even simpler like this to debug by just trying it to display the calculation on the screen:
Code:
#!/bin/bash
ASPECT=`mediainfo $1 |grep "Display aspect ratio" |cut -d : -f 2`
HEIGHT=`echo "320 / $ASPECT" |bc`
echo $HEIGHT
and it does the same, so it's definitely bc that won't accept the output from mediainfo.

How can pass values in args[0] and args[1] to Perl/CGI script?
I have made fallowing script for CGI scripting learning purpose:
Code:
#!/bin/sh
echo "Content-type: text/html"
echo
CMD='echo "$QUERY_STRING" | sed -n 's/^.*cmd=([^&]*).*$/1/p' | sed "s/%20/ /g" '
echo "<html>"
echo "<head><title>Hello CGI</title></head>"
echo "<body>" .....
echo "<input type=radio name=cmd value=ifconfig checked> ifconfig <br>"
echo "<input type=radio name=cmd value=uname> uname -a <br>"
This script works fine, but actually I quite don't understand it's inner working about those radio buttons.

I want to build on the code from /etc/apt/apt.conf.d/05etckeeper to work with Snapper, the new-in btrfs (et al) snapshot package.
Code: Select allDPkg::Pre-Invoke { "if [ -x /usr/bin/etckeeper ]; then etckeeper pre-install; fi"; };
DPkg::Post-Invoke { "if [ -x /usr/bin/etckeeper ]; then etckeeper post-install; fi"; };
The etckeeper code will work well as a template, but I need to pass a parameter between the pre- and post- instances. The parameter is obtained from the pre- invocation and passed to the post- invocation.I know that something similar to my quest is done with the 'pid' but how to do it in the 'standard' way. Happily there can't be multiple dpkg instances running concurrently (prevented by dpkg?) so I don't have to worry about that issue.
Q1. What is the 'standard' way of passing parameters about?
Code: Select allsnapper -c etc create -t pre -p (which 'prints' the parameter (int) to pass to the following invocation)
snapper -c etc create -t post --pre-number <parameter> in place of the two etckeeper calls.
Q2. How do I pick up the 'printed' output of the 'pre' call? I think it's just a 'get' from the stream but perhaps I've missed something.?
I started to run a C++ my program in Linux and I don't know how to test my program that works fine with a text file. This is a project for my uni and to explain more clear, My program is a sample database for modify or add and search and it read data from a binary file and also write into a binary file. I have got an input from my lecture and she said after compiling in Linux I must write:
1-to compile:
Code:
g++ (files with cpp)
2-to see the output:
Code:
./a.out
3-to test with input:
Code:
./a.out < input.txt >
My problem is in step three. What I must write in the command part after" step2" to see the output?
