Build of project not possible

[Raffro]

Hi, I am using cmake 3.21 vs 2017 checked out cppzmq-4.8.1 checked out zeromq-4.3.4 as per build instructions I built zeromq and after that cppzmq.

I am currently working on a service plugin for the Automotive Data and Time-Triggered Framework (ADTF). The code I write is written in c++. I generate the project with cmake and I built the projekt mostly manually via visual studio. I needed to implement a zmq socket, because of other modules. The generation of the .sln works but as I am building the plugin it says Result code '-20 '(ERR_NOT_FOUND) - Could not load plugin "...\recording_service\install\bin\debug\recording_service.adtfplugin" which is weird, because obviously the file is in the exact place.

Here is my cmakelists.txt:

cmake_minimum_required(VERSION 3.10.0)

include(CMakeListsSettings.txt)

find_package(ADTF REQUIRED COMPONENTS filtersdk ui)
find_package(ADTF_DEVICE_TOOLBOX REQUIRED COMPONENTS sdk)

### install(FILES ${CMAKE_CURRENT_BINARY_DIR}/recording_service.adtfenvironment DESTINATION .)

I have an additional CMakeSettings.txt where I set the paths to the both zmq source code folders:

set(cppzmq_DIR "C:/Work/03_Git/cppzmq-4.8.1/build")
set(ZeroMQ_DIR "C:/Work/03_Git/zeromq-4.3.4/build")

1. Can you help me out what is probably going wrong?
2. What is the minimum of files I need to include into my project, so that I can make use of the zmq (cppzmq) library?

If you have successfully build libzmq and cppzmq then this looks like a problem with ADTF.

[Raffro]

Thank you, I will keep this ticket updated when I receive feedback from the ADTF support.

On the other hand: what minimum artifacts do I need to include cppzmq to my project?

• I know that there is a release of libzmq which contains the dll, but how can I implement this within my cmakelists?
• As for cppzmq: is the zmq.hpp sufficient or is anythin else needed?

[Raffro]

Hi @gummif : It was an error by not specifying the 3rd party library.

But is it possible that I just link the libzmq.dll and the zmq.hpp file? How do I need to configure cmake, so that my plugin can be build without having everybody to have the zmq repos checked out...? Can you give me an example?
