Ubuntu :: Compiling And Running Some C++ Programs (with G++ From The Terminal)?
Jun 7, 2011
so i've just been sitting here, compiling and running some c++ programs (with g++ from the terminal), I looked away for one minute to open a file that had just been written out (opened it with gedit if that makes a difference), now my terminal says:kbuildsyscoca4 running...so I'm wondering if anyone knows what this is about?hy it suddenly started running and why it has appeared on my terminal. I'm basically just curious as I though bash shells were entirely separate virtualizations of shells, and unrepresentative of other processes. i'm also wondering what kbuildsyscoca4 is/does (i've got gnome going on and generally gnome varieties of programs). I found a post from about a year ago mentioning the same thing, though no replies.

I am new to C programming and I need a way to compile and run my code. I've made a little research and I found that eclipse is a nice IDE. But I don't know how to configure it and generally. What do I need to download and install to make it work. I've also tried downloading easy eclipse that doesn't need any configuration or extra files but the link on the site was broken. Is there any other C IDE like easy eclipse available?

I am trying to study gtk programming and get stucked before some errors in compiling them. Iam using ubuntu 9.10 and i didnt installed any additional libraries or packages for running these gtk programs assuming gtk is already installed in ubuntu. I am newbie to gtk I tried compiling some example programs from my tutorial and it ended up in errors. So do I need any additional packages to run these programs.when compiling it shows package config cannot find any gtk+-2.0 packages and to try specifying .pc in environment path. I don't know how to set these path stuff.

Trying to write a script for desktop launchers that are adaptable to screen resolution. Ideally, the program should:
1. Determine screen resolution:
if "a" use xdotool options window size 1305 x 869 px and move to 135,0
if "b" use xdotool options window size 1545 x 1019 px and move to 135,0
2. Check if program running:
if no, open program, and use "a" or "b" placement options, focus window
if yes, focus window
3. Close script and leave program open (if possible).
Problems arise when trying to use the script on programs that run from and hog the terminal
(e.g. brasero, gcalctool, nautilus)
Here the script will load the program, and nothing else (probably because it still occupies the terminal as it runs)
Code:
gcalctool && xdotool search "calculator" windowmove 135 0
This next command will cause the program to load, move, but it keeps focusing itself like xdotool is running the windowmove function constantly - it keeps focusing itself until script stopped.
Code:
gcalctool & xdotool search "calculator" windowmove 135 0
This had the same effect as the above code, but seems to work as a conditional subscript running when the process is running in the terminal - it just goes infinitely.
Code:
while [1] ; do xdotool search "calculator" windowmove 135 0 done exit
Is there some kind of "if, then" or "while, do" or some kind of conditional I can put in to the script ensure the window is moved only once if the program is running within the terminal? Is there a way to remove the program from the terminal from the script once it's been called?

I tried to compile C program that uses Openssl libraries on shell but got this error. I guess libraries are not linked properly.
undefined reference to SSL_library_init()

I am doing my project which detects and displays the error message along line number when compiling c programs under Linux. Using gcc command..cc command which we generally use. For which my program must act as a compiler and generate error messages when user program is written and compiled. My idea was to develop a shell script program using name suppose ncc that would be..
$ vi ncc.sh
echo "compiling program $1"
$cc MyPgm.c
$.a/.out
<esc>
:wq
Now user program pgm1.c can be compiled using
$ sh ncc.sh pgm1.c
This will invoke my compiler program. But the thing is how to pass user program pgm1.c as input to my compiler program...

Right now when I start a program from a terminal I can't use that terminal instance again until I close the program.
I am a new user of linux, and I want to know if there is a way to execute a program/application from a terminal without blocking the terminal until the program ends.

I want to compile program. "./configure" giving :
Code:
[kuba@Kuba-fedora uget-1.8.0]$ ./configure
checking for a BSD-compatible install... /usr/bin/install -c
checking whether build environment is sane... yes
checking for a thread-safe mkdir -p... /bin/mkdir -p
checking for gawk... gawk
checking whether make sets $(MAKE)... yes
checking for style of include used by make... GNU
checking for gcc... gcc
checking whether the C compiler works... yes
checking for C compiler default output file name... a.out
checking for suffix of executable .....
Configure: error: Package requirements (libnotify) were not met:
No package 'libnotify' found
Consider adjusting the PKG_CONFIG_PATH environment variable if you installed software in a non-standard prefix. Alternatively, you may set the environment variables LIBNOTIFY_CFLAGS
and LIBNOTIFY_LIBS to avoid the need to call pkg-config. See the pkg-config man page for more details. But I have the newest version of libnotify.

Ive had experience with simple installs which work with just

I am new to Slackware and I am wondering how you set the ARCH variable. On the multilib wiki page it says:
"Rather than editing the script and change/remove CFLAGS definitions, you can set the ARCH to 'x86_64' and save yourself some time."
So from this I understand that they advise against editing the Slackbuild script. How do I set the ARCH variable on the command line or is it a configuration file I need to edit? I am running Slackware 13.1 64.

I'm trying to get my head around compiling programs, and need some things clarified. Can anyone confirm or deny my understanding so far:
1) Program is written in high level language, such as C. File(s) of the program are the 'source code'.
2) Program is then 'compiled' to turn it into low-level code that is both hardware - i.e. Intel/AMD/ARM processor specific, and also Linux distribution specific. This resulting files are called the binaries.
3) I can go from source code to installed and usable program by doing these steps:
./configure
make
make install

I can't figure this out. If i run GUI program (in GNOME) from terminal. It doesn't works the same as if i run it from menus (or shortcut on desktop or panel). Or some times I run it from Alt+F2 method.
What is the difference in this methods?
For example what is the difference if i put this...
metacity --replace
...in terminal or in ALT+F2 dialog window. If I put it in terminal. GNOME doesn't work correctly. If i put it in Alt+F2 dialog window. It works as it should. With no problems.
And what is the difference if i like to run for example FireFox or gnome-control-center from terminal or select it from menus.
If i like to run from terminal. What would be right way to do it?
Because sometimes i get errors in terminal (but GUI works) sometimes after i close terminal GUI program closes to. Sometimes it doesn't. But if i run that program from menus (icons) there is no such problem. It just works. If i put & at the end of program. I can work in terminal. But still all of the above is still true.

I am try to compile and run JVLC (Java binding for VLC). I download it from the following link. [URL] It works on windows platform with eclipse. But I want to run on linux. I use openSUSE 11.2 and Netbeans 6.9.1. When I running it, it appear user interface but when I play it, I got the following error. The error is
Code: java.lang.UnsatisfiedLinkError: Error looking up function 'libvlc_video_set_parent': /usr/lib/libvlc.so.5.1.0
I thinks I miss "libvlc.so.5.1.0" package to install. But where I can get it. In my openSUSE I have already installed "libvlc5-1.1.3-1.2.i586.rpm". But I cannot found /usr/lib/libvlc.so.5.1.0 directory.

I recently learned how to add start up programs in the terminal using the following command:
Code:
ln /usr/bin/whateverprogram ~/.kde/Autostart
This worked, but now I want to remove some start up programs using the command line. Can someone point me in the right direction to what I need to do for this?
I'm assuming that default start up programs are not links in the ~/.kde/Autostart folder because when I run:
Code:
ls -a ~/.kde/Autostart
I only find the files that I have set to start up.

I am setting up a streaming audio server. I would like to have Darkice and sc_serv (Shoutcast server) start automagically on boot.
I have set Xubuntu (10.04) to auto login
Both Darkice and sc_serv are command line apps and I would like them to each run in their own terminal window so I can monitor any status messages they produce. For instance sc_serv displays connections disconnections with time connected, and current number of listeners, and I want to see that.
One important note: sc_serv must be up and running before Darkice can be started.

My problems is that after i've DL a program and then use unrar to open up the files...I was able to successfully mount a linux version game using Furious ISO mount (the game is Civilization call to power loki) Now I can see the files inside the folder but I can't figure out how to run the game after its mounted
I've looked around a lil bit and I know someone has probably asked this question before but most of what i find is people asking how to mount the image to begin with

Everything works fine; No problems running WinXP from an ISO, etc. I have several Windows only applications which I want to run on the WinXP VM. I cannot see the programs I have downloaded when using Explorer for Windows.Ordinarily, in a WinXP only system, I just find the program to be installed and double click on it to start the automatic installation routine.In this case, I cannot see any of the .exe files used for the install.I have placed those downloaded Windows application in the same directory on my Ubuntu Box as where VirtualBox, the Sun Guest Editions and the CD Image of the Garmin Trip and Map system.I installed the Garmin system directly from and ISO of the CD I made using Brasero. It works without a hitch.Should I take the Windows e.e programs and burn them to a CD and then transfer them as ISO tback to the VM drive?
