Compilation issues with CoAP client. #12

Open kulhadia opened 5 years ago

kulhadia commented 5 years ago

Hello, I am compiling the calvin-constrained with CoAP client and it fails. I am facing below-mentioned issues.

  1. In the Makefile (runtime/south/platform/x86/Makefile) CC_FLAGS, CC_LDFLAGS, and CC_LIBS entries are not retrieved as pkg-config command could not set the values for CC_FLAGS, CC_LDFLAGS, and CC_LIBS for libcoap package. ..... ifeq ($(LIBCOAP),1) CC_SRC_C += runtime/south/platform/x86/calvinsys/cc_libcoap_client.c CC_CFLAGS += -DCC_USE_LIBCOAP_CLIENT=1 CC_CFLAGS += $(shell pkg-config --cflags-only-I libcoap-1) CC_LDFLAGS += $(shell pkg-config --libs-only-L libcoap-1) CC_LIBS += $(shell pkg-config --libs-only-l libcoap-1) endif .......

As I could not locate the libcoap package by default, I installed it manually but I am not sure what to put into the .pc file for libcoap to make pkg-config command succeed.

libcoap Package installed : libcoap-1-0:amd64 4.1.2-1 amd64 C-Implementation of CoAP List of files owned by the package:

Could you please correct me if I am not following the right procedure to compile with coap client as compilation does not work for me out of the box.
Looking for your support.

Thanks!!

Hi,

If the package isn't available in your environment follow the installation instructions at https://libcoap.net/doc/install.html and change runtime/south/platform/x86/Makefile with:

ifeq ($(LIBCOAP),1) CC_SRC_C += runtime/south/platform/x86/calvinsys/cc_libcoap_client.c CC_CFLAGS += -DCC_USE_LIBCOAP_CLIENT=1 CC_CFLAGS += -I/usr/local/include/coap2 CC_LDFLAGS += -L/usr/local/lib -lcoap-2

CC_CFLAGS += $(shell pkg-config --cflags-only-I libcoap-1)

CC_LDFLAGS += $(shell pkg-config --libs-only-L libcoap-1)

CC_LIBS += $(shell pkg-config --libs-only-l libcoap-1)

endif

The Coap support in calvin-constrained has not been tested for a while and there was some errors and the library has been updated and I have updated calvin-constrained accordingly, so update the calvin-constrained repo to get the latest changes.

To test it first compile the constrained runtime with support for Coap:

make -f runtime/south/platform/x86/Makefile LIBCOAP=1 CONFIG="runtime/south/platform/x86/cc_config_x86_coap.h"

And to test it locally on the constrained runtime:

  1. Compile the calvin_scripts/temp_test.calvin script:

cscompiler calvin_scripts/temp_test.calvin python Tools/json2msgpack.py calvin_scripts/temp_test.json > calvin_scripts/temp_test.msgpack

  1. Start the constrained runtime with the temp_test script reading from a Coap source with URI coap://127.0.0.1:55654/3303/0/5700 (change it according to your environment):

./calvin_c -a '{"indexed_public": {"node_name": {"name": "constrained"}}}' -p '{"coap": {"actors": {"sensor.Temperature": "io.temperature"}, "capabilities": {"io.temperature": "coap://127.0.0.1:55654/3303/0/5700"}}}' -s calvin_scripts/temp_test.msgpack

To run it distributed with only the Coap actor on the constrained runtime:

  1. Start a calvin-base runtime:

csruntime -n 127.0.0.1 --name base

  1. Start a calvin-constrained runtime connecting to the base runtime.

./calvin_c -a '{"indexed_public": {"node_name": {"name": "constrained"}}}' -p '{"coap": {"actors": {"sensor.Temperature": "io.temperature"}, "capabilities": {"io.temperature": "coap://127.0.0.1:55654/3303/0/5700"}}}' -u '["calvinip://127.0.0.1:5000"]'

  1. Deploy a calvin-script that migrates a sensor actor to the constrained runtime:

temp : sensor.Temperature(period=1) snk : io.Print()

temp.centigrade > snk.token

rule device: node_attr_match(node_name={"name": "constrained"}) apply temp: device
