i am new to Debian. so can anybody send a link to Debian source code of configuring and installation. i know all linux commands, but i need step by step explanation to create Debian package of my project. which includes some jar files and some config files
thanks in advance
there is plenty of documentation on how to create a Debian package:
https://wiki.debian.org/HowToPackageForDebian
if you want to see a real-world example, you can get the code for any (official) package, by simply running apt-get source <mypackage>. E.g. the following command gets everything needed to create the hello Debian package (with the exception of build-dependencies):
apt-get source hello
This contains both
the code needed to create the deb with dpkg-buildpackage (everything contained in the debian/ subfolder)
and the original source code (everything outside of the debian/) subfolder).

I had downloaded sublime previously directly from the browser as tarball and saved it in a folder (and of course extracted it).But this way I wasn't able to make Sublime my default editor and it didn't feature as an application when I tried to open a text file with a right-click.I read somewhere installing sublime text 3 using commands:
sudo add-apt-repository ppa:webupd8team/sublime-text-3
sudo apt-get update
sudo apt-get install sublime-text-installer
will solve my problem. So I directly deleted the Sublime_text3 folder saved in my Downloads directory and then used the given commands. But when I entered the 3rd command line I got the following error(just writing the error part):
subprocess new pre-installation script returned error exit status 1
Errors were encountered while processing:/var/cache/apt/archives/sublime-text-installer_3126-2~webupd8~1_all.deb
E: Sub-process /usr/bin/dpkg returned an error code (1)
Can anyone explain why this error is coming and suggest a way to solve this problem? Also if anyone can tell how I can set Sublime as my default text editor from the tarball downloaded from the sublime text 3 website. Thanks in advance!
you can try this command to install Sublime Text using Snap Store..
sudo snap install sublime-text --classic
I'm not sure overall how to fix that error or what's going on (I use Slackware and not Ubuntu/Debian), but for a long while there have been official Sublime repositories several different Linux distributions, including Ubuntu/Debian.
It's highly recommended that you use those if you want to go the package route and not use existing solutions such as the one referenced in your question or in the other response here, if for no other reason than only the official repository is guaranteed to contain an unmodified version of Sublime. Additionally the official repositories are always updated on release, which may or may not happen in a timely manner in other repositories.
The links referenced above contain instructions on how to set up and use Sublime from those repositories, and if you have any issues a good place to ask is the forum.
One thing to note which isn't mentioned explicitly in the above pages is that to use the official repositories, you should:
Choose only one of them (stable or dev, noting that you need a license to run a dev version) and not add both repositories or things will not work as expected
Ensure that other repositories that you've added (such as the one in your question) are removed to make sure that the package system definitely pulls the correct package
There are a couple of ways to go if you want to install Sublime from the tarball version. The easiest way would be to extract it, then manually set up launcher shortcuts and so on based on what falls out. How exactly you would register it as a text editor in that case, I'm not entirely sure since I don't use the same distribution as you.
Presuming that the process would be easier if Sublime was installed in a way similar to how the package manager would do it, the tarball comes with a desktop file and icons, so the following steps can be used to (presumably) do what the package installer would do.
The proviso here is that although these steps work on my non-Ubuntu machine, I don't know if all of the referenced tools are installed by default on an Ubuntu system, so so more setup work may be involved.
Note also that the files in the tarball are not entirely self-consistent, which makes this a little bit more work.
First, you need to extract the tarball (replace tarball filename as appropriate for location and build):
cd /opt
sudo tar xvf ~/Downloads/sublime_text_3_build_3176_x64.tar.bz2
This creates the folder /opt/sublime_text_3/ and fills it with the contents of the tarball.
Next, you want to install the icons contained in the tarball. As far as I have been able to tell, the icons in the tarball aren't in the correct directory structure, requiring each to be copied into place individually. We also need to update the icon cache to ensure that the new icon is noticed by the system:
cd /usr/share/icons/hicolor/
sudo cp /opt/sublime_text_3/Icon/16x16/sublime-text.png 16x16/apps/
sudo cp /opt/sublime_text_3/Icon/32x32/sublime-text.png 32x32/apps/
sudo cp /opt/sublime_text_3/Icon/48x48/sublime-text.png 48x48/apps/
sudo cp /opt/sublime_text_3/Icon/128x128/sublime-text.png 128x128/apps/
sudo cp /opt/sublime_text_3/Icon/256x256/sublime-text.png 256x256/apps/
sudo gtk-update-icon-cache -f -t .
Now we want to install the sublime_text.desktop file that is in the tarball. Note however that like the icons, it seems kind of broken; the tarball extracts to sublime_text_3 but the desktop file assumes that the application is actually in /opt/sublime_text instead.
As such, you either need to rename the folder that was extracted to sublime_text to match what is in the desktop file, or edit the desktop file to make the path correct.
The following steps assume that we want to keep the folder the same and rewrite the desktop file. These commands will generate a new file named sublime_text_3.desktop with the changes.
cd /opt/sublime_text_3/
sed -e "s^/sublime_text/^/sublime_text_3/^" sublime_text.desktop | sudo tee sublime_text_3.desktop
Now you can install the desktop file. You do that with desktop-file-install, passing it the name of the desktop file. For accessing Sublime from the command line, you also want to set up a subl link to the installed copy of Sublime.
Adjust the paths as appropriate here if you decided to rename the folder instead of editing the desktop file:
sudo desktop-file-install sublime_text_3.desktop --rebuild-mime-info-cache
sudo ln -s /opt/sublime_text_3/sublime_text /usr/bin/subl
At this point Sublime should show up as an installed application, or at least it does in my Window Manager; if not, executing sudo update-desktop-database may help refresh it.
You can try this once. i hope it will help

I spent all day trying to make Host sFlow 2.0.6-1 from sources (https://github.com/sflow/host-sflow/releases) for XenServer 7.0 using the XenServer DDK from this site: http://xenserver.org/overview-xenserver-open-source-virtualization/download.html
First I had to make 2 changes to the file hsflowd-xen.spec:
Changed line 3 to: "Version: 2.0.6" (it was still 2.0.1)
Changed line 20 to: "%setup -n hsflowd-2.0.6-1" (added the name because the default one was wrong).
Now my problem is that I dont have the xenstore.h file. After long searches I found that it's in the package libxen-dev (or libxen-devel) but I couldn't find it with its dependecies anywhere.
The four most probable solutions I think are :
1. (The lazy one) Get the iso file for Host sFlow already built for XenServer 7.0 (the official site stopped building at 6.5)
Set up a proper yum repository that will contain libxen-dev and its dependencies. I can't even connect to the official CentOS repositories because the files in /etc/yum.repos.d/ have a bad URL.
This is the content of /etc/centos-release: "XenServer DDK release 7.0.0-125770c (xenenterprise)"
Somehow manage to use 'xenstore.a' instead of 'xenstore.h'. I changed the code in src/Linux/mod_xen.c to include 'xenstore.a' instead of 'xenstore.h' but when I build it, it creates a new file with the old code and ignores my changes. I probably changed the wrong files because there are different copies of the whole code. I'm not even sure it would work though even if I did manage to include 'xenstore.a'.
Make xenstore from sources. I didn't try it because I only found old sources and I figured I'd miss the dependencies too.
PS: I'm n00b at CentOS and Makefiles in general so the solution might be obvious and I just don't know it.
With gratitude to lagange, I updated the host-sflow project with a XenServer 7 build. I also added a Docker recipe so you can replace all these steps with just "./docker_build_on xenserver". Please raise issues on https://github.com/sflow/host-sflow.
I finally succeeded in building it. That's what I had to do step by step:
Import the XenServer DDK 7.0.0 into XenCenter.
Extend xvda1 following these steps: https://support.citrix.com/article/CTX125405
Make these changes to hsflowd-xen.spec:
3rd line: Version: 2.0.6
20th line: %setup -n hsflowd-2.0.6-1
Add these two lines before %description:
%define debug_package %{nil}
%define _unpackaged_files_terminate_build 0
Change file /etc/yum.repos.d/CentOS-Base
Change all occurrences of "$releasever" to "7".
Change all occurrences of "$basearch" to "x86_64".
Change "enabled=0" to "enabled=1" for each repository.
Uncomment baseurl lines for each repository.
Mount the Development packages (binpkg.iso available on the xenserver.org download page) and add a file for it in /etc/yum.repos.d/
Mine looks like it:
[binpkg]
name=CitrixXenServer7
enabled=1
baseurl=file:///mnt/binpkg/
gpgcheck=0
Install the two following packages with Yum (dependencies should install correctly now):
xen-libs-devel.x86_64
xen-dom0-libs-devel.x86_64
Make the file and install it using this tutorial: https://raw.githubusercontent.com/sflow/host-sflow/v2.0.4/INSTALL.XenServer
I want to host an apt-get repository.
How do I package my application, and how do I host it in a repository for use?
The application relies on Java, MySQL, upstart and is configured to run on boot as an upstart service.
The answer should also include, how to host the package on a repository.

Good question, maybe a personal ppa is what you are looking for. After you finish you will have to do a $ sudo add-apt-repository ppa:myApp/ppa. Then you can apt-get install it.
To package your application you will need to do this in your apps directory
myappFolder$ dh_make -p myApp_1.0 --createorig
To create a original tar of your app. This will also create a Debian folder with a control file, a rules file, changelog... Change the values in these files to fit how your package should be. Specifically the control file. You will have a Depends: field where you can write in packages your application relies on such as Java and MySQL, make sure to have the same names as Ubuntu repository for these things.

Check out chapter 5 the install file and then building the package in chapter 6. I use dpkg-buildpackage usually. debuild -us -uc is good too look up too.
Then create an account on Ubuntu launchpad.
https://login.launchpad.net/+new_account
Sign the Ubuntu code of conduct:
https://launchpad.net/codeofconduct (take away the extra h, no reputation for more links)
Activate a PPA:
https://launchpad.net/people/+me/ (extra h)
Then follow this guide to upload the package to your ppa:

I got these links from a great answer on ask.ubuntu. It's also got a more lengthy answer on creating a deb package.
https://askubuntu.com/questions/71510/how-do-i-create-a-ppa
I have a debian package that I built that contains a tar ball of the files, a control file, and a postinst file. Its built using dpkg-deb and it installs properly using dpkg.
The modification I would like to make is to have the installation directory of the files be determined at runtime based on an environment variable that will be set when dpkg -i is run on the deb file. I echo out the environment variable in the postinst script and I can see that its set properly.
My questions:
1) Is it possible to dynamically determine the installation directory at runtime?
2) If its possible how would I go about this? I have read about the rules file and the mypackage.install files but I don't know if either of these would allow me to accomplish this.
I could hack it by copying the files to the target location in the posinst script but I would prefer to do it the right way if possible.
Thanks in advance!
So this is what I found out about this problem over the past couple of weeks.
With prepackaged binaries you can't build a debian package with a destination directory dynamicall determined at runtime. I believe that this might be possible if installing a package that is built from source where you can set the install directory using configure. But in this case since these are embedded Ubuntu machines they don't have make so I didn't pursue such an option. I did work out a non traditional method (hack) for installing that did work. Since debian packages simply contain a tar ball relative to / simply build your package relative to a directory under /tmp. In the postinst script you can then determine where to copy the files from the archive into a permanent location.
I expected that after rebooting and the automatic deletion of the subdirectory under /tmp that dpkg might not know that the file package existed. This wasn't a problem. When I ran 'dpkg -l myapp' it showed as still installed. Updating the package using dpkg/apt-get also worked without a hitch.
What I did find is that if you attempted to remove the package using 'dpkg -r myapp' that dpkg would try and remove /tmp which wasn't good. However /tmp isn't easily removed so it never succeeded. Plus in our situation we never remove packages but instead simply upgrade them.
I eventually had to abandon the universal package due to code differences in the sources resulting in having to recompile per platform but I would have left it this way and it did work.
I tried using --instdir to change the install directory of the package and it does relocate the files but dpkg fails since the dpkg file can't be found relative to the new instdir. Using --instdir is sort of like a chroot. I also tried --admindir and --root in various combinations to see if I could use the dpkg system relative to / but install relocate the files but they didn't work. I guess rpm has a relocate option that works but not Ubuntu.
You can also write a script that runs dpkg-deb with a different environment for 6 times, generating 6 different packages. When you make a modification, you simply have to run your script, and all 6 packages gets generated and you can install them on your machines avoiding postinst hacking!
Why not install to a standard location, and simply use a postinst script to create symbolic links to the desired location? This is much cleaner, and shouldn't break anything in dpk -I.
I am trying to install mod_java on ubuntu.
I have installed the latest java(1.6).
I have configured freeswitch with mod_java module enabled in module.conf.xml
then when i run the make file, it says:
freeswitch_java.h:5:17: error: jni.h: No such file or directory
I have searched through the java installtion folders, but did not find any include folder or jni.h.
Can anyone help, what is being the problem here.
Thanks for reading this question.
I had the same problem. The solution was to run configure with the option --with-java:
./configure --with-java=/usr/lib/jvm/java-1.6.0-openjdk/include/
I don't know if it makes any difference but I added mod_java after building freeswitch without it. It was disabled in my initial build in module.conf.xml but afterwards I ran the above command plus:
make mod_java-install
It worked for me on ubuntu with openjdk. Are you using the Sun JDK? Maybe in the version you have dont have the include folder which has the source files. Try installing the other JDK. Or try and see of ther are some other related packages in apt that will get you the include folder.
Type this linux command to locate your jni.h file on your filesystem.
locate jni.h
you should be able to get it somewhere
in /usr/lib/java directory or some other directory
depending upon your java home.
copy paste the jni.h in src/include folder of your freeswitch src.
It will throw you some more errors for different .h files
just copy all of them to your src/include folder.
in latest freeswitch, installing through Makefile, its not possible to configure as the Makefile downloads and installs. Its possible by modifying the Makefile.in file to add the include path
mod_java_la_CPPFLAGS
-I/usr/lib/jvm/default-java/include \
