General :: Compiling Programs - Steps For Producing Executable
Oct 19, 2010
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

Does linux kernel 2.6 support suid & guid?. I just read somewhere that "latest linux kernels does not support suid & guid as it can pose a security risk if the setuid attribute is assigned to executable programs that are not carefully designed". I need a confirmation about what I say is correct or if not please correct me.

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 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.

Those are not present directory in /usr/src/linux is not present. My goal is to compile modular programs.

I get heaps of errors from Okular saying that /tmp/kde-luke/* cannot be opened. I think it is doing this because I downloaded files from Firefox and opened them then closed firefox before closing the pdf files. I have tried uninstalling a purging Okular deleting the applications stuff in my home directory but it is still obsessed with these files. The only way I have been able to stop these annoying pop ups is by having the application uninstalled or running a starup script that will create these files on boot.

I'm used to holding the left Alt and entering the ASCII character whenever I'm using an unknown keyboard configuration and want to type a special character. For example, Alt-092 makes a backslash (). That's on Windows. Is there a way to do this in Ubuntu ?
Note : I also want to be able to use this in console mode. That means I don't want a solution involving a software with a GUI.

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 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...

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.

I have created a small script to compile a network weathermap using the cacti RRD files. The script reads the *.conf files and outputs an html and a png file. When I manually run the script it works normally.
I have edited my crontab with the crontab -e command to run this script every minute
The problem is script itself works when I manually call it but when it is run using crontab it doesn't do anything. The cron.log shows that the script IS being run every minute with no errors but the files (html and png) do not get written. What am I doing wrong and how do troubleshoot this?

Just a heads up. I just found out about a free online book called Producing Open Source Software. It's great.
I just used a trunk checkout and the directions here to make myself an epub version:
[url]
EDIT AGAIN: don't download the epub version from here:
[url]
If you get it there, then the table of contents doesn't work. Make the epub version yourself, and you have a table of contents.

I am running into a snag on .exe files in Lucid. I have Wine installed, but I can not open the file as it is blocked from executing with a window popping up telling me that this file was blocked due to security reasons. I go into the files properties and try to change the permission but that does not help. Is there a way to get around this? Possibly in the terminal as root?

I'm trying to install PyPedal but was overwhelmed by the steps. Here is a link to the program:[URL]..The first problem is, on this page [URL].., the package is described as .tar.gz, however when I try to download, the package is a .egg I searched online since I never dealt with a .egg, some suggest to use the unzip command others have used the command without success.
The second problem is, I have to install Python which I have no experience with. This the Python page[URL].all the Linux files seem to be source tarball. What would be the best way to install a source as I have never done this before? The third problem is, which of the third-party extensions used by PyPedal listed in this link I could skip installing [URL].. . All I interested in is getting the numerical result that this program produces. Assume that I have download the PyPedal and Python files to the /home directory.
