When using the apt-get install method to install a package onto ubuntu, is there any fundamental difference between obtaining the source code for that package and building it from scratch? Does the apt-get install functionality simply download source and build it on your machine to a specified directory or is there more going on behind the scenes ?
Finally (maybe this has no answer) is one method better than the other? What I am angling at here is does the build it yourself from source code have any advantages or is it better to let apt-get do its thing?

I have read a lot of threads with similar questions, but after reading the answers, I am very confused. I have found in them lots of url's with repositories but people discusses about which repositories are made for one or two versions of ubuntu, but I have found nothing about 11.10 version. Is too soon to ask for that? Should I downgrade my ubuntu to have a realtime kernel?

I used source code to build one package such as below:
./configure --prefix=/usr --sysconfdir=/etc --localstatedir=/var --libexecdir=/usr/lib --with-package-name="Myplugin" --with-package-origin="http://www.ubuntu.org/" --enable-gtk-doc --disable-static
make
make install
But unfortunately, i discovered that its the latest version, and has lot of bugs, so i need to remove it/uninstall it. But how can i do so? I tried make clean; make uninstall but still i see it exist:
# pkg-config --list-all | grep Myplugin
myplugin-....
$ ls /usr/lib/myplugin/libXYZ.so
exist....
How do you remove this now?

I need to install asterisk 1.6.2.18 on Ubuntu 10.10
I would like to know what the configure options were that were used to generate the ubuntu package of asterisk 1.6.2.7.
My favorite server distro is Slackware and on that I just reference the Slackbuild file to find out how a package was made and possibly customised in order to remake it with a newer source, but I cannot figure this out on Ubuntu. I am under time pressure now, so I would appreciate some pointers.
Thank you!

I'm trying to compile a kernel for a 32bit single-core Intel Atom machine. Needless to say, the compile is taking inordinate amounts of time. It's been going for 2 hours and it's still only halfway through the driver modules.
Compiling a kernel on my main desktop only takes 15 minutes but it's a 64bit machine. Can I cross compile to generate a 32bit kernel package from the better machine?

I want to build the Empathy in Ubuntu 11.04.
When I follow the build process,
./autogen.sh
The shell said to me that
libtoolize: copying file `m4/lt~obsolete.m4'
checking for autoconf >= 2.53...
testing autoconf2.50... not found.
testing autoconf... found 2.67
checking for automake >= 1.9...
testing automake-1.11... found 1.11.1
checking for libtool >= 1.5...
testing libtoolize... found 2.2.6b
checking for glib-gettext >= 2.2.0...
testing glib-gettextize... not found.
***Error***: You must have glib-gettext >= 2.2.0 installed
to build Empathy. Download the appropriate package for
from your distribution or get the source tarball at
ftp://ftp.gtk.org/pub/gtk/v2.2/glib-2.2.0.tar.gz
But when I cannot find the way to install glib. What should I do
to install that in ubuntu 11?

I would like ./configure to link to a library and some include files. My library is stored in /home/foo/sw/lib/ and my files are stored in /home/foo/sw/include.
./configure --help throws out the following:
Some influential environment variables:
CC C compiler command
CFLAGS C compiler flags
LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
nonstandard directory <lib dir>
LIBS libraries to pass to the linker, e.g. -l<library>
CPPFLAGS (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
you have headers in a nonstandard directory <include dir>
CPP C preprocessor
I have tried various combinations:
./configure --prefix=/home/foo/sw -I</home/foo/sw/include> -L</home/foo/sw/lib/>
./configure --prefix=/home/foo/sw -I=/home/foo/sw/include -L=/home/foo/sw/lib/
./configure --prefix=/home/foo/sw -I/home/foo/sw/include -L/home/foo/sw/lib/
etc..
But I can't seem to get the syntax right. If anyone can help me out, that would be greatly appreciated. THANKS!

I have a bug in a Linux kernel module that causes the stock Ubuntu 14.04 kernel to oops (crash).
That is why I want to edit/patch the source of only that single kernel module to add some extra debug output. The kernel module in question is mvsas and not necessary to boot. For that reason I don't see any need to update any initrd images.
I have read a lot of information (as shown below) and find the setup and build process confusion. I need two recipes:
- to setup/configure the build environment once
- steps to do after editing any source file of this kernel module (
.c and .h) and converting that edit into a new kernel module (.ko)
The sources that have been used are:

How do I install node.js in Ubuntu? I've been looking around, and I can't find anything. Is there a Ubuntu package for node.js, or do I have to compile it myself?
