Install failing with ROS Melodic

[shmpwk]

Thank you for your interesting work!

I'm trying the How to Build (Ubuntu Linux Melodic install).

My environment is ubuntu18.04 on WSL2 and ROS Melodic.

I have an error when installing system dependencies like

$ rosdep install --from-paths src --ignore-src -r -y
ERROR: the following packages/stacks could not have their rosdep keys resolved
to system dependencies:
roscpp_azure_iothub: Cannot locate rosdep definition for [libazure-iot-sdk-c]
Continuing to install resolvable dependencies...
#All required rosdeps installed successfully

As a result, I failed to catkin_make

$ catkin_make install

This is because the dependency is listed as libazure-iot-sdk-c source
While it is registered in rosdep as azure-iot-sdk-c source

Perhaps it's possible to change the entry in the package.xml?

In the meantime you can manually apt install ros-melodic-azure-iot-sdk-c

Disclaimer: not a maintainer here, but I released the azure-iot-sdk-c to the ROS buildfarm because it takes ages to compile.

Thank you for your quick response!
You are right, and it is solved!!!

by

sudo apt install ros-melodic-azure-iot-sdk-c

and edit package.xml
from

<?xml version="1.0"?>
<package format="2">
  <name>roscpp_azure_iothub</name>
  <version>0.0.1</version>
  <description>
  This package interfaces with Azure IoT Hub to provide cloud-based device management and command and control services over Azure IoT C99 SDK.

Finally,

$ rosdep install --from-paths src --ignore-src -r -y
#All required rosdeps installed successfully

P.S. I've tried source build but it makes the problem more complicated, but ros-melodic-azure-iot-sdk-c really helped me.

Can you leave the issue open? It is probably still valid for other users.
