Code For The Project Development

I have just installed a new debian OS and want to change a file.
For some reason, gedit didn't come pre-packaged so I installed it with apt-get.

When I use a terminal as root, gedit won't open. I get the following error message:
Code:

gedit grub
(gedit:3679): EggSMClient-WARNING **: Failed to connect to the session 
manager: Authentication Rejected, reason : None of the authentication
protocols specified are supported and host-based authentication 
failed

Gedit will open page files on the desktop - but not on the terminal.
Is this because I haven't done something with the new install or should I remove gedit and reinstall?

Is there a way to have a script called source, that can be run without the full path?

Ex:
When I run:
export PATH=/home/user:$PATH
source

I get:
Code:

$ source
bash: source: filename argument required
source: usage: source filename [arguments]

However I want it to run my script called source:
Code:

$ cat source 
#!/bin/bash
echo "Hello World"

Is there way to override a shell builtin in the PATH var or some other way?

Hi all,

I am trying to simulate leach on NS2 but I've had problems with running the leach_test. I've followed all steps from installing NS2 up to installing the LEACH patch (used the latest one from exidus). Here's the error message in the leach.err I found.

Code:

couldn't read file "/mit/uAMPS/uamps.tcl": no such file or directory
    while executing
"source.orig /mit/uAMPS/uamps.tcl"
    ("uplevel" body line 1)

    invoked from within
"if [$instance_ is_http_url $fileName] {
set buffer [$instance_ read_url $fileName]

} else {

    (procedure "source" line 8)
    invoked from within

    (procedure "source" line 8)
    invoked from within

    (file "tcl/ex/wireless.tcl" line 187)

Your help are very much appreciated, thanks!

hi,
i need source code for clustering and source prefix aggregation in wireless sensor network using tcl in ns2.please help me.

I am using scientific linux. In the directory user/project/Build, after I ran 'make' to compile and link all the cpp files,I had no problems. But then, when I went to directory user/run/run.sh, which runs the project binary in user/project/Build/bin/project, I get a segmentation fault error. In the directory user/run, I enter 'gdb' in the command prompt and get the message "*** No targets specified and no makefile found. Stop."

What am I supposed to do to detect the segmentation fault?

Hi Everybody.....
I'm new to this site and new to Linux ( Ubuntu 12.04) generally. I am an old goat mechanical engineer with years of electronic instrumentation design experience. I am connecting several of my old HP digital oscilloscopes and logic analyzers to a Ubuntu box via GPIB (ieee 488) interface. I have the interface working well using the open source ( Sourceforge) "Linux-GPIB" kernel module. I can remotely control the instruments using "Linux-GPIB"'s "ibterm" terminal utility. However "ibterm" doesn't provide a means to do a scope screen dump to a file. A guy on EEBLOG published a short C language 30 line source code to perfome this function. Unfortunately it isn't a package with makefile.am, makefile .in, configure etc which I understand I could compile using the typical ./config, make, checkinstall procedure. It is just the c source code text. Soooo.....do I use gcc directly? If so, how do I run gcc in a manner to be able to uninstall all the various files it will make? Or ?? What is the procedure for automake in this situation ? Or....? I'm kind of lost. Your suggestions would be helpful.
Cheers.

Currently taking my first linux course in college and am stuck on a project...details he https://aacc.instructure.com/courses...item_id=614603

So far this is the code I have come up with but get an error on the 42nd line where it says done. I am not an expert by any means but would like to not struggle and finish this project. Below is my code...any input welcome.

Hi. I have some doubts regarding “LEACH” protocol. I’m using ns-2.34 on Ubuntu 10.04 and patched leach protocol by following below link. I got ‘leach.out’ file, but I didn’t get ‘leach.err’ file.

https://abdusyarif.wordpress.com/201...-step-by-step/

Then I want to check out the leach source code file. The source code of the leach is not found in that folder. I ran out the leach test file and I’ve got a warning message.

I've just installed Ubuntu 14.04 LTS on my virtual machine,(it's a little bit too slow but this is not my main problem), I want to install mplayer on it, I've downoaded mplayer source code with binary codecs (essentials) from the official website, I read carefully the install and readme docs, but once I type "./onfigure --enable-gui"
I got a message like : "gc error, cc could not excute ...." is there any help ?

NB : I don't have internet access

Hi, I've just recently installed MySQL connector/c from source code on my Slackware 14.1 x64

I read the official instructions of the connector but I felt a bit disorientated when I read:
Code:

1 -Change location to the top-level directory of the source distribution.

I interpreted that I have to go to the "highest" directory Code:

/

So I wrote: Code:

 
        #                            cd /

root@- /#                            tar xzvf /home/normal/Downloads/mysql-connector-c-6.1.6-src.tar.gz 

root@- /#                            cd /mysql-connector-c-6.1.6-src/

root@- /mysql-connector-c-6.1.6-src# cmake -G "Unix Makefiles"

root@- /mysql-connector-c-6.1.6-src# make 

root@- /mysql-connector-c-6.1.6-src# make install

Then I did:
Code:

ln -s /usr/local/mysql-5.6.25/include /usr/include

But when I try to compile a program in c with #include <mysql.h> i get this error:
Code:

# gcc ctemp.c 
In file included from ctemp.c:2:0:
/usr/include/mysql.h:57:27: fatal error: mysql_version.h: No such file or directory
 #include "mysql_version.h"
                           ^

What can I do? Thanks a lot and sorry for poor english
