Environment Details (include every applicable attribute)

  • Operating System+version: Ubuntu 20.04
  • Compiler+version: gcc8
  • Conan version: 1.39
  • Python version: 3.8.10

Steps to reproduce (Include if Applicable)

I'm in the process of converting a embedded linux appliaction from checked in dependencies in the repo to using conan.

[generators]
cmake


[options]
paho-mqtt-cpp:shared=False
paho-mqtt-cpp:ssl=False
botan:enable_modules=pubkey,rsa,emsa_pkcs1

The package paho-mqtt-cpp has a dependency to paho-mqtt-c.

If I now execute the command

 conan install . --profile ./scripts/gemmi.profile --install-folder build-conan --build=missing

in the yocto environment the paho-mqtt-c package gets build correctly. But while configuring the paho-mqtt-cpp package
cmake can't find the paho-mqtt-c library. See logs.

If I exceute conan install for the host system all buidls without an error.

Hi @ukaiser

I suspect this could be something in the paho-mqtt-cpp/1.2.0 recipe, that could be failing for some cross-compile scenario. Maybe related conan-io/conan-center-index#3760?
Pinging @uilianries in case he could help here.

One of the first things that could be tried is cross-compiling that recipe for another architecture, for example, and see if the recipe in general is able to cross-compile successfully. If it does, then probably is related to "sysroot"-like specifics of the Yocto environment, and CMake using some other find module instead of the Conan generated one.

I agree, it should be related to cross-compiler + PahoMQTT. I would move this issue to conan-center-index.

Besides that, we need the profile used to try to reproduce. However, using the Docker image conanio/gcc9-armv7hf, all build fine. Of, course, is different from Yocto, but still is cross-building.

My full log:

Based on the output:

paho-mqtt-cpp/1.2.0: Generator cmake_find_package created Findeclipse-paho-mqtt-c.cmake
...
CMake Error at /opt/fslc-framebuffer/2.8-snapshot/sysroots/x86_64-fslcsdk-linux/usr/share/cmake-3.14/Modules/FindPackageHandleStandardArgs.cmake:137 (message):
  Could NOT find PahoMqttC (missing: PAHO_MQTT_C_LIBRARIES
  PAHO_MQTT_C_INCLUDE_DIRS)

My bet is that the build is using other find module, probably belonging to yocto cmake or something like that.

Yes, it sounds something affected by Yocto environment which is changing the Cmake root module path, like, searching on Yocto folders instead of using Conan folders.

hello @uilianries !
I had a similar problem when developed on Yocto.
I remember I had to patch the CMAKE_FIND_ROOT_PATH like it's described here.
Could you please check whether this is relevant for your case?

@dornbirndevelops Excellent find, let's see if it works for @ukaiser
