However, the "bug" as described is a result of how the code is designed to work in both Debian and Ubuntu. > dpkg-cross by default removes lot of files from converted packages. This is to prevent file conflicts with the original package. i.e. if you need files from a package which are removed from the cross package by dpkg-cross, you need to ensure that the native version of that package is installed. dpkg-cross only cares about specific files types in the -cross package - typically files which are architecture-dependent and which are easily identifiable as such. > Effect it that sqlite3 can not be cross built because > tcl8.5-dev-armel-cross package does not contain tclConfig.sh (which was > present in tcl8.5-dev_armel.deb). So install tcl8.5-dev_amd64.deb and tcl8.5-dev-armel-cross. This script is a "build-tool", it is not a "cross-build-dependency" in that it is not a header file, it is not a pkg-config file and it is not used when linking the cross built application. The file is therefore not architecture-dependent and cannot be handled by dpkg-cross. Retitling this as a documentation bug so that the manpage is clearer on what dpkg-cross can and cannot be expected to perform. If having the amd64 package around causes trouble, discuss with the tcl maintainers whether the script can be put into a -dev-common package or whether some more standard tool like pkg-config can be used instead. This is a recurring problem in cross-building. dpkg-cross cannot leave these files in place or the -cross package won't install. In an ideal world, it would be nice if cross builds had a completely clean build environment without native build-deps but that is not reality. Many packages have architecture-independent support scripts which behave no differently whether the build is native or cross. There is nothing dpkg-cross can do about this except explain it in the manpage. If the script doesn't generate the correct config when cross-building, file a bug with Tcl to get the script to accept a parameter which can be handled in the cross build. Simply moving the script to somewhere under /usr/lib/arm-linux-gnueabi/ is not going to help you. -- Neil Williams ============= http://www.data-freedom.org/ http://www.linux.codehelp.co.uk/ http://e-mail.is-not-s.ms/
