Problem building own application in yocto

jko — Fri, 30 Sep 2016 11:38:32 GMT

I'm trying to compile our own application using Yocto for a phyFlex board but am not able to get it running.

Following the Makefile

CFLAGS=${KERNEL_SRC}
CFLAGS=-lrt -lpthread
#CFLAGS += -I../../platform-Spectro2/build-target/linux-2.6.24/include/

#CFLAGS += -D_GNU_SOURCE
CFLAGS += -g

all: automat

automat: automat.c
automat +: vm/vm.c vm/vm.h vm/componentdefs.c vm/componentdefs.h vm/blobtags.h vm/spectrometer.c vm/spectrometer.h speconfig/speconfiglib.c speconfig/speconfiglib.h
automat +: vm/chemometry.c vm/chemometry.h vm/chemoengine.h vm/textfile.c vm/textfile.h vm/tcpsocket.c vm/tcpsocket.h vm/datastore.c vm/datastore.h vm/dynamicdefs.c vm/dynamicdefs.h
automat +: vm/configuration.c vm/configuration.h vm/realtimeclock.c vm/realtimeclock.h vm/visualization.c vm/visualization.h
automat +: CANopen/CANopen.c CANopen/CANopen.h CANopen/mcp2515.c CANopen/mcp2515.h CANopen/lock.c CANopen/lock.h CANopen/Event.c CANopen/Event.h CANopen/CanBasic.c CANopen/CanBasic.h
automat +: CANopen/ComObj.c CANopen/ComObj.h CANopen/nmt.c CANopen/nmt.h CANopen/ObjDict.c CANopen/ObjDict.h

clean:
rm automat

and this is how my .bb looks like (the last version i've tried)

DESCRIPTION = "autod"
SECTION = "automat"
LICENSE = "MIT"
LIC_FILES_CHKSUM = "file://${COMMON_LICENSE_DIR}/MIT;md5=0835ade698e0bcf8506ecda2f7b4f302"
PR = "r0"

SRC_URI = "file://Makefile"

S = "${WORKDIR}"

EXTRA_OEMAKE = "'CFLAGS=${CFLAGS} -lrt -lpthread -I${KERNEL_SRC} -g'"

do_install() {
oe_runmake all:
install -d ${D}${bindir}
install -m 0755 automat ${D}${bindir}

and finally the error

ERROR: Function failed: do_configure (log file is located at /opt/PHYTEC_BSPs/phyFLEX-i.MX6/build/tmp-glibc/work/cortexa9hf-vfp-neon-phytec-linux-gnueabi/automat/0.1-r0/temp/log.do_configure.12497)

I'm really new into yocto and kernelbuilding in general. Any hints are very appreciated!

Hi Jakub

one can look at hellow world building steps :

Hi Igor,

i had no problems with including a simple "Hello World" example, but I don't get i how to compile our application using a bitbake recipe based on our makefile. I've been using ptxdist and rules in the first place but the current versions of the phytec BSPs are based on Yocto.

Best regards
