I want to use vfprintf with the char * on 64-bit. Here is the sample code:
[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:
[code]...
I have installed the 32-bit libraries (gcc-gfortran.i686, glib.i686, libstdc++.i686).
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 have a minimal ubuntu desktop and i'm trying to install the latest nvidia driver (downloaded from their website) and i got the following error:

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>
#include<stdlib.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.
m trying to compile a package hdf-1.6.8 for openSUSE 11.0. But i think there is a problem when gcc 4.3 is used. The make fails giving errors like:

Is this a cause for conflicts between gcc 3 and gcc 4. If so how do i rectify the same? I have compat-ltdc++ installed. Similar errors are sure to follow during the compilation process.

I was just confused because in Centos 5.5 it works fine.
When i type 'ifconfig eth0 192.168.25.1 255.255.255.0' the outcome is 'SIOCSIFADDR : invalid argument', but when i check the ip address using /sbin/ifconfig i see the ip address is updated to 192.168.25.1 and is up. When i restart the linux box,the /sbin/ifconfig is reset to 192.168.100.1 .what should i do so that the linux box /sbin/ifconfig should not change when am rebooting.

I'm having trouble getting subversion working on Centos 4.7. When I try to create a repository using:
Code:
svnadmin create /path/to/repo
I get:
Code:
svn: Berkeley DB error while creating environment for filesystem repo/db: Invalid argument
svn: bdb: Berkeley DB library configured to support only DB_PRIVATE environments
I've searched the Net, with little luck. Threads seem to suggest that Centos has this flag compiled into the Berkeley DB RPM by default; whereas SVN doesn't want it. Someone, somewhere, must have got this to work and I'm sure it's something really simple I'm doing wrong.

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?

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.
