As it happens zlibg1-dev has not been installed. dpkg reports:-

Well the failures I get are to do with the failure to install zlib1g-dev. libz.so is not found, and the relevant headers are not found. So it looks as though although apt-cross may think it is installed, it has not been. But there are no other errors or warnings between these and the failure. At the point of failure I get:- checking for strings.h... yes checking for inttypes.h... yes checking for stdint.h... yes checking for unistd.h... yes checking for gzdopen in -lz... no configure: error: zlib library not found See `config.log' for more details. make: *** [build-tree/config.status] Error 1 dpkg-buildpackage: failure: debian/rules build gave error exit status 2 And zlib should have been installed which is part of zlib1g-dev.. This worked just fine with the i386 build, this is the first time I have tried a cross architecture build. David
