The actual support for cmake in OE worked until now that I only had "simple" dependencies. Now with QT as as dependency, I use the cmake FindQt4 Module that strongly relies on qmake to find the different QT cmake variables (try to run ${STAGINGBINDIR}/qmake4 -query). The problem is that FindQt4 does not find the qmake4 (as I have proposed to rename it like that in my patch from yesterday) since the CMAKE_FIND_ROOT_PATH given to the cmake cmd in the classes/cmake.bbclass only is set to -DCMAKE_FIND_ROOT_PATH=${STAGING_DIR_HOST} that does not include ${STAGING_BIN_DIR}. Setting it to -DCMAKE_FIND_ROOT_PATH=${STAGING_DIR} makes configure fail (it cannot find the needed header files); and with -DCMAKE_FIND_ROOT_PATH="${STAGING_DIR_HOST};${STAGING_DIR}" qmake4 is not found either. So if someone who knows cmake better than me can tell me how to give two paths to a cmd -DPATH_NAME=VALUE1 VALUE2 for cmake (and what would be the equivalent to STAGING_DIR_HOST for ${STAGING_DIR}/i686-linux in my case) that would help a lot (I am not sure it can be achieved). All the inputs are greatly appreciated and if you could help me for the OE var names (especially for the equivalent to ${STAGING_DIR_HOST} that would point to ${STAGING_DIR}/i686-linux, that would already be a good start) Thanks a lot -- Valentin Longchamp, PhD Student, EPFL-STI-LSRO1 valentin.longchamp@epfl.ch, Phone: +41216937827 http://people.epfl.ch/valentin.longchamp MEA3485, Station 9, CH-1015 Lausanne
