Hi,
It seems that pdebuild somehow calls 'debian/rules' before going to the pbuilder environment and so it fails as some build-deps are required to run this 'debian/rules' but not available in the call environment. In my case it is 'debian/rules' that includes some .mk files that are provided by the build-deps. I just found the following lines in the pdebuild script that may be responsible for this (not sure at all!): $ grep -H -n -C 3 "rules" /usr/bin/pdebuild /usr/bin/pdebuild-86- SOURCE_OPTIONS=$(get_source_options) /usr/bin/pdebuild-87- eval dpkg-source ${SOURCE_OPTIONS} --before-build . /usr/bin/pdebuild-88- if should_clean_source; then /usr/bin/pdebuild:89: "${BUILDSOURCEROOTCMD}" debian/rules clean /usr/bin/pdebuild-90- fi /usr/bin/pdebuild-91- eval dpkg-source ${SOURCE_OPTIONS} -b . /usr/bin/pdebuild-92- if ! [ "../${DSC}" -ef "${BUILDRESULT}/${DSC}" ]; then Why such a step is not done inside the pbuilder environment if this is required? Then is there a way to avoid such a step in my case? Thanks, Patrice
