The package metadata / selection is processed with this rules. The raw
listing can be obtained with:
scripts/Create-PkgList x86
But one usually would not do so, despite core script debugging.
Note that modern targets do not use cryptic Unix tool magic for the
selection but rather plain/text files, such as:
target/rescue/pkgsel:
O * # unless otherwise noted below
X 00-dirtree
X sysfiles
...
Where X is select and O deselect. The new rules even allow including
selection templates as the desktop target does:
target/desktop/pkgsel:
# let's reuse a reliable base
include target/generic/pkgsel/50-minimal-desktop.in
Only more complex, purely embedded etc. target still rely on sed
to tweak details, such as to only build the compiler toolchain for
the build host, not the target:
target/embedded/config.in:
...
# we need those for some broken packages that need updating
/ automake / { s,^. [^ ]*,X 0---------,; p; d; }
/ libtool / { s,^. [^ ]*,X 0---------,; p; d; }
..
Sorry for this beginner question, but i don't undestand the build
proccess completely.
Any question is welcome, just ask!
