maybe mbpoll is not cloned? I found the custom-rts.c file on the mbpoll website and try to search for it in the build directory, but I can't find anything my mbpoll_1.4.11.bb file: SUMMARY = "bitbake-layers recipe" DESCRIPTION = "mbpoll recipe" LICENSE = "CLOSED" SRC_URI = "git://github.com/epsilonrt/mbpoll" SRCREV = "2bf602817370000e69221eb50c4ece813d10c0b4" DEPENDS = "libmodbus" S = "${WORKDIR}/git" inherit pkgconfig cmake
again, any particular reason why you're poking the recipe by hand instead of just using devtool (which perfectly works in this case)? it would even give you a good start on the licenses, as well as not having missed the inherits.
