Name
Debian::DpkgCross - Package of dpkg-cross commonly used functions The 2.x series of dpkg-cross is seeking to achieve its own removal by incorporating as much cross-building support as possible into dpkg itself. The number, scope and range of functions supported by this package is therefore only going to decrease. Any newly-written code using this package will need to keep up with changes in dpkg. Developers are recommended to join the debian-dpkg and debian-embedded mailing lists and keep their code under review.

Bugs
Please report bugs via the Debian Bug Tracking System.
Support
All enquiries to the "<debian-embedded@lists.debian.org"> mailing list.
MAKEFLAGS
See bug #437507 Even if the other flags are needed CC, GCC and other compiler names should *NOT* be overridden in $ENV{'MAKEFLAGS'} because this prevents packages compiling and running build tools using CC_FOR_BUILD. CDBS packages need to declare an empty override variable in debian/rules: DEB_CONFIGURE_SCRIPT_ENV= Depending on progress with dpkg cross-building support, the remaining overrides may also be removed. Do not rely on these being set.
read_config
Read '$conffile' and save the definition in global variables all recognised variables. '$crossroot' will be set by setup(). Until setup() is called all "crossroot-<arch>" settings are stored within '%allcrossroots'. All package variables are stored within '%conf'. No variables are skipped. return: none
get_config
Return the current configuration from read_config as a hash reference.
get_version
Return the current DpkgCross version string used by all dpkg-cross scripts.
dump_debug_data
Return a hashtable of assorted debug data collated during the current run that can be processed using Data::Dumper.
rewrite_pkg_name
Converts a package name into the dpkg-cross package name. $1 - the package name to check and convert if needed return - the cross-package name
convert_filename($)
Converts an original .deb filename into the dpkg-cross .deb filename or converts a dpkg- cross .deb filename into the original .deb filename. returns undef on error
get_architecture
Returns the current architecture. return: Current architecture or empty if not set.
check_arch($arch)
Checks that the supplied $arch is (or can be converted to) a DEB_HOST_GNU_TYPE that can be supported by dpkg-cross. returns the DPKG_HOST_GNU_TYPE or undef
setup
Set global variables '$arch', '$crossbase', '$crossbin', '$crosslib32', '$crossdir', '$crossinc', '$crosslib', '$crosslib64', '$crossprefix', '$compilerpath' and '$deb_host_gnu_type' to defaults and substitute them with variables from '%conf' and '$arch'. return: none
create_tmpdir($basename)
Safely create a temporary directory $1: Directory basename (random suffix will be added) return: Full directory pathname, undef if failed
convert_path($multiarch, $path)
Convert path, substituting '$crossinc', '$crosslib', '$crosslib64', '$crosslib32', '$crossdir', allowing for multiarch paths. This function will be used while building foreign binary packages or converting GCC options. $1: Multiarch sub-directory to strip $2: Directory (and file) to convert. return: Converted path.
simplify_path($path)
Simplify path. Remove duplicate slashes, "./", "dir/..", etc $1: Path to simplify. return: Simplified path.
