= Build-Cross-Depends packages =

This page seeks to build a list of packages that have to be available on the build host as native packages and as cross packages, installed using dpkg-cross or apt-cross.


== auto-apt ==
auto-apt was considered as a tool to identify these cross dependencies but the first results were not exciting:

 1. empdebuild needs a source of dependencies processed by dpkg-cross.
 1. auto-apt can obtain packages when requested from a repository
 1. apt-cross needs to be more intelligent and check if a cross-package is available rather than always building it afresh.
 1. debian/xcontrol can specify the packages required for empdebuild.
 1. debian/xcontrol is in SVN (as a patch)
 1. the toolchain repository already contains some cross packages.
 1. use auto-apt -L to write a log file: parse to create xcontrol.
 1. auto-apt does not create it's database on installation, need to copy it or update it. Yuk.
 1. auto-apt slows down the build enormously - too slow to use routinely. Also consumes all memory.
	Therefore: only recommend when first emdebianising.
 1. logfile option (-L) does not work. (DebianBug:426854).
 1. auto-apt automation would try to install fortran compilers etc.
 1. auto-apt fails to locate the emdebian toolchain sources. (DebianBug:426851).
 1. auto-apt fails to detect the need for cross-built libraries:
{{{
# auto-apt -L -y run emdebuild -a arm
...
dpkg: /usr/arm-linux-gnu/lib/libpam.so.0 not found.
dpkg: /usr/arm-linux-gnu/lib/libselinux.so.1 not found.
dpkg: /usr/arm-linux-gnu/lib/libc.so.6 not found.
dpkg-shlibdeps: failure: dpkg --search gave error exit status 1
dh_shlibdeps: command returned error code 256
make: *** [binary-arch] Error 1
make: Leaving directory `/opt/trunk/c/cron/trunk/cron-3.0pl1'
sh-3.1# ls
}}}

Currently, the rest of this page is just a list of what I had to install for certain packages.
