[yocto] Problem bitbaking <custom>server.cpp (Iotivity) in Yocto

[Natalia Theologou]

Hello all,


I have also sent this email to iotivity list.

I am following the template of iotivity-simple-client inside recipes-apps in order to bitbake my custom simple server and simple client.

The client succeeds in bitbaking but the server has the errors:


Log data follows:

My .bb file is as follows:



SUMMARY = "Iotivity Simple server"
DESCRIPTION = "Iotivity Simple server example which talks to the Simple Server example."
HOMEPAGE = "https://www.iotivity.org/"
DEPENDS = "iotivity"
SECTION = "apps"
LICENSE = "Apache-2.0"
LIC_FILES_CHKSUM = "file://nickserver.cpp;beginline=1;endline=19;md5=fc5a615cf1dc3880967127bc853b3e0c"

SRC_URI = "file://iotivity-nick-server.tar.gz \
          "

S = "${WORKDIR}/iotivity-nick-server"

TARGET_CC_ARCH += "${LDFLAGS}"

IOTIVITY_BIN_DIR = "/opt/iotivity"
IOTIVITY_BIN_DIR_D = "${D}${IOTIVITY_BIN_DIR}"

do_install() {
    install -d ${IOTIVITY_BIN_DIR_D}/apps/iotivity-nick-server
    install -c -m 555 ${S}/nickserver ${IOTIVITY_BIN_DIR_D}/apps/iotivity-nick-server
    install -c -m 444 ${S}/oic_svr_db_server.dat ${IOTIVITY_BIN_DIR_D}/apps/iotivity-nick-server
}

FILES_${PN} = "${IOTIVITY_BIN_DIR}/apps/iotivity-nick-server/nickserver \
               ${IOTIVITY_BIN_DIR}/apps/iotivity-nick-server/oic_svr_db_server.dat"
FILES_${PN}-dbg = "${IOTIVITY_BIN_DIR}/apps/iotivity-nick-server/.debug"
RDEPENDS_${PN} += "iotivity-resource"
BBCLASSEXTEND = "native nativesdk"

and my makefile:


YOCTOCXXFLAGS=-I$(PKG_CONFIG_SYSROOT_DIR)/usr/include/iotivity/resource/ -I$(PKG_CONFIG_SYSROOT_DIR)/usr/include/iotivity/resource/stack -I$(PKG_CONFIG_SYSROOT_DIR)/usr/include/iotivity/resource/ocrandom -I$(PKG_CONFIG_SYSROOT_DIR)/usr/include/iotivity/resource/logger -I$(PKG_CONFIG_SYSROOT_DIR)/usr/include/iotivity/resource/oc_logger

YOCTOLDFLAGS=-loc -loctbstack -loc_logger

all: nickserver

nickserveroff.o: nickserver.cpp
ifeq ($(PKG_CONFIG_SYSROOT_DIR),)
    echo "Error: Yocto cross-toolchain environment not initialized"
    exit 1
endif
    $(CXX) -std=c++0x -c -o $@ $< $(YOCTOCXXFLAGS)

nickserver: nickserver.o
    $(CXX) -o nickserver nickserver.o $(YOCTOLDFLAGS)

clean:
    rm -rf nickserver *.o



I have -std=c++0x in the makefile which is the same  as -std=c++11, so I don't know why it has the error: #error This file requires compiler and library support for the ISO C++ 2011 standard. This support is currently experimental, and must be enabled with the -std=c++11 or -std=gnu++11 compiler.

Also the client succeded in bitbaking and it has the same makefile and the same .bb recipe.

Has anyone any idea regarding this?


Thank you in advance!


Best,
Natalia
