Hello, Chris, I've already seen the MAVEN always fetches the current state of Boost, which is a problem when changing interfaces.
Here we have to download a defined version of Boost when loading Boost from Maven and then CMAKE finds the Boost Library and can set the variables correctly. Currently, setting the variables for Boost is set in the parent CMAKE and all sub CMAKE then use the variables.

Hi Markus, I just pulled your latest changes, uncommented the parts that will not compile on Mac / Linux and am currently working on the build / maven stuff. I did change that I pulled the boost stuff down to the root and updated the BOOST_ROOT to: set(BOOST_ROOT "./target/boost_1_70_0/") Most seems to be working with this ... but still the logger module is complaining to not be able to find the boost includes ... I'm currently trying to find out what's wrong there. Regarding the loading of modules ... doesn't boost have some abstraction for this? I thought Boost is there to abstract from exactly these types of differences between the OSes.

Auf Basis das Connectiontyps S7, ModBus, etc. wird die DLL dynamisch nachgeladen. The connection is implemented. The next steps are: Generation via Maven/CMAKE Reporting telegrams to the reassigned levels vie Signal2 Implementation of telegrams with new procedure of automatic generation Currently, however, the driver can only be compiled with CMAKE under Windows. Why? The interface for loading the DLL is different between Windows and Linux. As part of the Maven customizations, we would also make the customizations for Linux. So far we have created the CMAKE files for creating the PLC4CPP driver. We haven't deleted the Maven parts yet. This would be the procedure for generating the complete driver: Starting the BOOST Library generation process via Maven(as now) Start Plc4x CMAKE process via MAVEN We haven't done that much with Maven yet, we still have to get used to it. Chris might be able to do the integration in a Telko.

Hi All and especially Markus, I just wanted to hear what the C++ part is up to. I can see a commit every now and then in the s7-cpp branch, but not much discussion (Actually none at all). Would be cool, if you could give us all an update to what you’re up to. Also would I like to tackle the problem of being able to fully build C++ from the maven build. We had discussed the options a while ago, but nothing has happened so far. I think the way I understood our last state we decided to: * Get rid of all the intermediate pom.xml files and all the Maven packing and unpackeing of stuff * Concentrate fully on starting one CMake build in the plc4cpp root pom and have that build all modules * We do the packaging using the maven assembly plugin which is also defined in the plc4cpp module So I have a few questions: * How do we integrate the downloading and building of boost in this szenario? * Do we simply copy the boos build stuff to execute before running the CMake build in the plc4cpp module? * Do we add something to the CMake build that takes care of this? * Currently can’t come up with the second question ;-) Chris
