From 731b60afcb3d318581af7f4e1ac9a66f9e12f1a5 Mon Sep 17 00:00:00 2001 From: Laura Abbott Date: Fri, 18 Oct 2019 13:29:08 -0400 Subject: [PATCH] tools: iio: Correctly add make dependency for iio_utils iio tools fail to build correctly with make parallelization: $ make -s -j24 fixdep: error opening depfile: ./.iio_utils.o.d: No such file or directory make[1]: *** [/home/labbott/linux_upstream/tools/build/Makefile.build:96: iio_utils.o] Error 2 make: *** [Makefile:43: iio_event_monitor-in.o] Error 2 make: *** Waiting for unfinished jobs.... This is because iio_utils.o is used across multiple targets. Fix this by making iio_utils.o a proper dependency.
