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.

All enquiries to the "<debian-embedded@lists.debian.org"> mailing list.
See bug #437507 Even if the other flags are needed CC, GCC and other compiler names should *NOT* be overridden in $ENV{'MAKEFLAGS'} because this prevents packages compiling and running build tools using CC_FOR_BUILD. CDBS packages need to declare an empty override variable in debian/rules:
DEB_CONFIGURE_SCRIPT_ENV=
Depending on progress with dpkg cross-building support, the remaining overrides may also be removed. Do not rely on these being set.
Read '$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
Return the current configuration from read_config as a hash reference.
Return the current DpkgCross version string used by all dpkg-cross scripts.
Return a hashtable of assorted debug data collated during the current run that can be processed using Data::Dumper.
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
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
Returns the current architecture.
return: Current architecture or empty if not set.
Checks that the supplied $arch is (or can be converted to) a DEB_HOST_GNU_TYPE that can be supported by dpkg-cross.
returns the DPKG_HOST_GNU_TYPE or undef
Set global variables '$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
Safely create a temporary directory
$1: Directory basename (random suffix will be added)
return: Full directory pathname, undef if failed
Convert path, substituting '$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. Remove duplicate slashes, "./", "dir/..", etc
$1: Path to simplify.
return: Simplified path.
