Sorry, I meant to follow this but I am not subscribed to the list - please cc
me in your response.
A script does not have to be *too* intellegent to do this - adding an
environment variable to the rules package at the configure line should
suffice. At this point (at least from all the packages I've torn apart and
looked at), it appears that it will work. The only problem will come when
there are conflicting configure commands... i.e. " --with-package
- --disable-package" . I *believe* the last configure options passed will take
precedence, so the ENV var I will use will go towards the end. Dirty, but it
will work. If I am wrong, please let me know.
I will not use DEB_BUILD_OPTIONS - it will be a temporary var called
DEB_CONF_FLAGS - only used for the nefarious purposes of adding "bloat" and
"extra features" to your packages.
As to modifying packages, I am compiling a seperate file that lists Package:
and Flags, with optional flags as well. I am stealing most of the flags from
Gentoo Portage - their ebuilds list USE (IUSE) flags for each package, so why
dig through and do the dirty work again? In fact, the process of declaring
what you wish to use is, at this point, very similiar to gentoo's use system.
Whether you think it will work or not, we are going to do it. It won't be
pretty (overnight), but we're talking about a 0.0.1 implementation here -
proof of concept.
I will do what I can "beyond the boundaries of fantasia" and you can either
use it or not. If you still don't like it - well, you don't have to use it.
I appreciate the ideas that some have posted. Thanks for your help! You can
keep track of the progress (or help out!) at www.debtoo.org - we have cvs and
a new website coming soon. We've already modified apt-build to include CFLAGS
and CXXFLAGS and you can (mostly) rebuild your (optimized) system with your
own -Ox and -march flags. It's just these stupid configure flags that are
