One more strange observation the merge_config.sh shall use -native binaries (like bison, gcc, etc). Unfortunately, in my case it depends on target ones (as we do have CFLAGS = .... ARCH=arm ... merge_configs.sh). The bitbake -g -u taskexp virtual/kernel shows however that we do depend on native bison. To provide target ones - I do need the do_prepare_recipe_sysroot() to call before do_configure. > > Bruce > > > (Poky) SHA1: bb91b2ae3ee5cf108aa2f9b78abb14d5aa00831d > > > > Signed-off-by: Lukasz Majewski <lu...@denx.de> > > --- > > meta/classes/kernel-yocto.bbclass | 1 + > > 1 file changed, 1 insertion(+) > > > > diff --git a/meta/classes/kernel-yocto.bbclass > > b/meta/classes/kernel-yocto.bbclass index 4ac3a39e47..19a3f2bc46 > > 100644 --- a/meta/classes/kernel-yocto.bbclass > > +++ b/meta/classes/kernel-yocto.bbclass > > @@ -276,6 +276,7 @@ do_kernel_metadata[depends] = > > "kern-tools-native:do_populate_sysroot" > > do_validate_branches[depends] = > > "kern-tools-native:do_populate_sysroot" do_kernel_configme[dirs] += > > "${S} ${B}" +do_kernel_configme[depends] += > > "virtual/kernel:do_prepare_recipe_sysroot" do_kernel_configme() { > > set +e > > > > > Best regards, Lukasz Majewski -- DENX Software Engineering GmbH, Managing Director: Wolfgang Denk HRB 165235 Munich, Office: Kirchenstr.5, D-82194 Groebenzell, Germany Phone: (+49)-8142-66989-10 Fax: (+49)-8142-66989-80 Email: w...@denx.de
