Logs to Console just started

Ubuntu 20.04, Cross Compiled on Ubuntu 20.04 using GCC 9.4.0

Release LTS_01_2023_Ref02

After removing my build folder and doing a fresh build now running my app I'm seeing these strange logs to console.

Heres' some of them: -> Header (AMQP 0.1.0.0) <- Header (AMQP 0.1.0.0) -> [OPEN] {b2dcc7b2-b4ba-496d-9b41-1a6869da2804,vf-iot-hub.azure-devices.net,4294967295,65535,240000} <- [OPEN] {DeviceGateway_1731daea4384420db01debe47112ad26,localhost,65536,8191,120000,NULL,NULL,NULL,NULL,NULL} -> [BEGIN] {NULL,0,4294967295,100,4294967295} <- [BEGIN] {0,1,5000,4294967295,262143,NULL,NULL,NULL} -> [ATTACH] {$cbs-sender,0,false,0,0, {$cbs}, {$cbs},NULL,NULL,0,0} -> [ATTACH] {$cbs-receiver,1,true,0,0, {$cbs}, {$cbs},NULL,NULL,NULL,0} <- [ATTACH] {$cbs-sender,0,true,0,0, {$cbs,NULL,NULL,NULL,NULL,NULL,NULL,NULL,NULL,NULL,NULL}, {$cbs,NULL,NULL,NULL,NULL,NULL,NULL},NULL,NULL,NULL,1048576,NULL,NULL,NULL} <- [FLOW] {0,5000,1,4294967295,0,0,100,0,NULL,false,NULL} -> [TRANSFER] {0,0,<01 00 00 00>,0,false,false} <- [ATTACH] {$cbs-receiver,1,false,0,0, {$cbs,NULL,NULL,NULL,NULL,NULL,NULL,NULL,NULL,NULL,NULL}, {$cbs,NULL,NULL,NULL,NULL,NULL,NULL},NULL,NULL,0,1048576,NULL,NULL,NULL} -> [FLOW] {1,4294967295,1,99,1,0,10000} <- [DISPOSITION] {true,0,NULL,true, {},NULL} <- [TRANSFER] {1,0,<01 00 00 00>,0,NULL,false,NULL,NULL,NULL,NULL,false} -> [DISPOSITION] {true,0,0,true, {}}

Here is the CMake I'm using.

set(CMAKE_IOTHUB_ARGS "-Duse_prov_client=OFF -Dno_logging=ON")

ExternalProject_Add( azure-iot GIT_REPOSITORY https://github.com/Azure/azure-iot-sdk-c.git GIT_TAG "LTS_01_2023_Ref02" GIT_SHALLOW true PREFIX ${IOT_PREFIX} CMAKE_ARGS "${CMAKE_IOTHUB_ARGS}" INSTALL_COMMAND "" )

Any idea on the issue?

I also see a lot of -> [DETACH] {5,true} -> [DETACH] {6,true} -> [DETACH] {2,true} -> [DETACH] {3,true} -> [DETACH] {4,true} -> [DETACH] {0,true} -> [DETACH] {1,true} -> [END] {} -> [CLOSE]* {}

AND

-> Empty frame -> Empty frame -> Empty frame <- Empty frame -> Empty frame -> Empty frame -> Empty frame -> Empty frame

I have tested this with code in our main branch and it works as expected when I'm using CMake (I prefer using ccmake):

Running iothub_client/samples/iothub_ll_telemetry_sample/iothub_ll_telemetry_sample.c doesn't give me any logs when the build is configured this way:

With logging on (default), I get:

It is very likely that the CMAKE_ARGS are not taking effect and you are building with defaults. Unfortunately, I'm not at all familiar with how ExternalProject_Add works.

I would first try out running cmake manually for our project and test with one of the samples, ensuring that all submodules have been properly updated and rebuilt (most logging above is from the uAMQP submodule dependency).

Thanks CIPop! that pointed me in the right direction. I needed to put double quotes around each arg.

set(CMAKE_IOTHUB_ARGS ${CMAKE_ARGS} "-Dno_logging=ON" "-Duse_prov_client=OFF" )
