apt-build for Debian
--------------------
apt-build is an orphan package. If you want to adopt it, see
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=365427
WARNING:
--------
-> Do not upload packages on Debian:
If you patch and compile your own packages with apt-build, you
should not upload Debian packages built with a such system, because
it can distort a program's behavior.
-> Please keep deb and deb-src line in sync in your sources.list.
-> About sources.list and apt/preferences:
The deb line of apt-build repository must be the first line if
you want apt-get to prefer built packages than other packages.
To avoid conflicts with the `/etc/apt/preferences' mechanism,
you may add the following entry in the '/etc/apt/preferences' file,
or the '/etc/apt/preferences.d/aptpinning' file:
# Set Pin-Priority 800 to all local files
Package: *
Pin: origin ""
Pin-Priority: 800

------------------------------ FAQ -----------------------------------
----------------------------------------------------------------------
Q: gcc and g++ do not seem to be called with good options!
A: *** They are called with them! ***
What you see on your screen is the command called by make, but
the wrapper wraps (yeah, it does) calls to gcc/g++ and adds options you
specified in the apt-build configuration file.
You won't see this on your screen.
Try `ps ax | grep gcc' instead as a proof, while building.
----------------------------------------------------------------------
Q: Can I rebuild gcc or g++?
A: If you rebuild gcc, it seems that optimizations won't be applied
because it uses its own compiler during building.
----------------------------------------------------------------------
Q: What should be the size of my build directory?
A: This directory should be large enough to contain packages and their
build output. Some packages require at least 1 Go to be built.
----------------------------------------------------------------------
Q: How do I rebuild my whole system (apt-build world)?
A: You must create a package list first.
The simplest way to do it, is to run:
dpkg --get-selections | \
awk '{if ($2=="install") print $1}' > /etc/apt/apt-build.list
You should edit this file to remove some packages like gcc, kernel...
Please note that using the --reinstall switch can be useful.
