i am following a sample called
paho_iot_provisioning_sample (here is the doc: github.com/Azure/azure-sdk-for-c/blob/main/sdk/samples/iot/README.md) to implement Azure DPS to generate devices in Azure IoT hub.
I managed to generate the certificate X.509 and i need to build and run the sample but i am blocked (github.com/Azure/azure-sdk-for-c/blob/main/sdk/samples/iot/README.md#build-and-run-the-sample).
The prerequisites from the doc is:
Have Microsoft [vcpkg](https://github.com/mimqtcrosoft/vcpkg) package manager and [Eclipse Paho MQTT C client](https://www.eclipse.org/paho/) installed.
I managed to install
vcpkg but the installation of
eclipse paho mqtt C client is more complicated.
cmake -DTRANSPORT_PAHO=ON .. output an error:
CMake Error at sdk/samples/iot/CMakeLists.txt:16 (find_package): By not providing "Findeclipse-paho-mqtt-c.cmake" in CMAKE_MODULE_PATH this project has asked CMake to find a package configuration file provided by "eclipse-paho-mqtt-c", but CMake did not find one. Could not find a package configuration file provided by "eclipse-paho-mqtt-c" with any of the following names: eclipse-paho-mqtt-cConfig.cmake eclipse-paho-mqtt-c-config.cmake Add the installation prefix of "eclipse-paho-mqtt-c" to CMAKE_PREFIX_PATH or set "eclipse-paho-mqtt-c_DIR" to a directory containing one of the above files. If "eclipse-paho-mqtt-c" provides a separate development package or SDK, be sure it has been installed.
I found the
eclipse-paho-mqtt-cConfig.cmake file and set the new location in
CMakeLists.txt located in
azure-sdk-for-c/sdk/samples/iot like so:
but i got a new error:
CMake Error at C:/Users/Azure-iothub-dps/src/CMakeFiles/Export/lib/cmake/eclipse-paho-mqtt-c/eclipse-paho-mqtt-cConfig.cmake:87 (message): The imported target "eclipse-paho-mqtt-c::paho-mqtt3c" references the file "C:/Users/Azure-iothub-dps/src/CMakeFiles/Export/lib/libpaho-mqtt3c.dll.a" but this file does not exist. Possible reasons include: * The file was deleted, renamed, or moved to another location. * An install or uninstall procedure did not complete successfully. * The installation package was faulty and contained "C:/Users/Azure-iothub-dps/src/CMakeFiles/Export/lib/cmake/eclipse-paho-mqtt-c/eclipse-paho-mqtt-cConfig.cmake" but not all the files it references.
and it can not find the file
libpaho-mqtt3c.dll.a anywhere. Any idea ?
