It says exactly the same. But you are confusing the flag, -MF is about naming the output dep filename, i.e. ompi-optg/obj/sys/objects/init.d in your example, that is just fine, I do get that file with that name. My issue is with the contents GCC writes within that dep file, specifically the TARGET, which can be specified with -MT, but it is cumbersome to do, unless you use "-MT $@", though no idea how to update configure for that. -- Lisandro Dalcin ============ Research Scientist Extreme Computing Research Center (ECRC) King Abdullah University of Science and Technology (KAUST) http://ecrc.kaust.edu.sa/
