You’ll need to have deb-src lines for each source, and all sources listed in one file.

ie:

deb http://some.software.repo….
deb-src http://some.software.repo….

then you can use apt build like:

apt-build -sources-list /path/to/list install somepackage

Some repositories might not have a source repo (due to licensing or copyright problems or whatever) if this is the case, it’s ok to ignore apt-build complaining about it. Software distributed as binary-only cannot be optimised per architecture.

Could you explaine a litte more about the right sources to get apt-build to download all the sources.

Many of these issues in apt-build have been fixed. The documentation has not been updated unfortunately (neither has apt’s for that matter)

I have found that having multiple source lists (in /etc/apt/source.list.d/) prevents apt-build from getting a full list of sources.

It only reads ONE source file (default /etc/apt/sources.list), so I made a redundant file „/etc/apt/apt-build.sources” containing all my sources and use the parameter „–sources-list /etc/apt-build.sources” with every call to apt-build.

Hi@ALL

i run apt-get world –reinstall –force-yes -yes
and always apt-build stops cause it doesn’t diffrent find sources?

Thanks for Help..

â€œâ€¦set your environment variables before you run it!:

[â€¦]

Otherwise your regular CFLAGS (and all of /etc/apt/apt-build.conf) will be ignored.â€

Nope, what you see are the commands called by make. Apt-build uses a wrapper (apt-build-wrapper; probably in /usr/lib/apt-build/) wich adds the options from apt-build.conf. Read README.Debian (propably in /usr/share/doc/apt-build/).

The real gcc calls youâ€™ll see after typing â€˜ps ax | grep gccâ€™.

I had to put the following in my APT preferences file in order to make apt-get choose a package from the local repository over a package from the remote repository. Note that priorities over 1000 have a special meaning; see the apt_preferences man page.

Package: *
Pin: release o=apt-build
Pin-Priority: 1001

Awesome work. Thanks!

It’s true; without „–force-yes”, you will just get a reinstall of the same old binary package! Furthermore, all your optimizations are ignored anyway! It seems that apt-build is an old, half-baked attempt, and really is just a „novelty” item – unless you use something like this:

apt-build install –rebuild –reinstall –yes –force-yes

…set your environment variables before you run it!:

export CFLAGS_APPEND=”-O3 -march=pentium3 -fomit-frame-pointer”

export CXXFLAGS_APPEND=$CFLAGS_APPEND

Otherwise your regular CFLAGS (and all of /etc/apt/apt-build.conf) will be ignored. See the manpage for dpkg-buildsource for more info. BTW, the command-line options for apt-build behave slightly different that the documentation claims; hence –reinstall AND –rebuild together. With a little cleaning up, apt-build could be a great utility. If you want USE flags – USE=”gentoo” =)

And?
Can you quantify the improvement in term of speed?

I highly doubt it changes anything if you already have a libc6-686
