Hi Markus, thank YOU for the first C++ code :)
One of the reasons I had a deeper look into CMake was the ability to configure builds using a variety of systems. One of them is Visual Studio. It should be possible to have Maven generate the configuration needed to build things in Visual Studio [1]. What version are you using? Perhaps I can come up with a comman-line, which you can simply use.

Chris thanks for building the toolchain. Just adapt our other sources to the toolchain and the gcc compiler.

Now boos only build the "System" module which speeds up the build dramatically. Also did I notice one little thing: When building boost on Windows, it adds an annoying "boost-1_69" directory in between. So I had to add a second include directory for windows machines. Unfortunately this contains the boost version. As we manage the versions in the pom.xml this is unfortunate, so I had to have the CMakeLists.txt file be processed by Maven before actually building. So what happens now in a build is: - the src/main/cmake/CMakeLists.txt file is copied to target/cmake/CMakeLists.txt and all variables in it are replaced by maven properties. - the target/cmake/CMakeLists.txt is used to generate the build in target/make - the make build is run in target/make the output is in target/make/libapi.a (for the API module) Think I will have to sign up for helping the CMake project guys to get some issues in the cmake plugin fixed ... there is great room for improvement. But I'm happy it's working now. Will probably fine-tune some things as I come up with solutions for them.

From a quick look its seems as if you were using a "multiprecision" and "functional" module. But when having the "b2.exe" show me a list of all modules these weren't listed. Could you please provide me with a list of options for a minimal build? I would take over and make sure it runs on all main platforms after that ...

Boost is a collection of individual libraries, mostly based on templates. i.e. Later, we do not have to compile the entire Boost library platform-specific. Many concepts of the C ++ standard have been developed many years ago in the environment of Boost. If we want to Support the area of embedded system, we can only use C / C ++ in my view. According to the current state, we would like to follow the Java API and thus reduce the maintenance hell. Best regards, happy new year.

So now it seems I have finished a first version of a Maven build that is able to compile the C++ API module which Markus provided us with. I had to tweak the code a little, but now it seems I was able to build on 64bit machines with Mac, Linux (Ubuntu) and Windows 10. In contrast to Java, C++ doesn’t have a nice an simple library repository. Also wouldn’t the binaries built on a mac be runnable on Windows for example. Markus’ initial code used a library called “boost” which seems to provide a platform independent abstraction of some of the essential things we need (Sockets, Types, …) So next to the “api” module is a “libs” module, which does nothing else than download an build any required third party libraries and to install them in the “libs/libs” directory. This directory is then explicitly imported in the builds of the other modules (currently just the API) As building the boost lib takes a very, very long time, I decided to have it only built, if the “libs/libs” directory is missing. So if you are building for the first time … get yourself a big cup of coffee. Hopefully we’ll be able to strip that build down to the parts we need and not compile everything. The build itself is performed with a tool called “CMake”. This claims to be a meta-build system that allows generating everything needed to build with a variety of other build systems. On windows it requires a gcc compliant compiler to be installed. I decided to go down the mingw path. So if you want to build from the commandline with a Windows system, be sure to install that first and to add the bin directory of that to your systems PATH. (http://sourceforge.net/projects/mingw-w64/files/Toolchains%20targetting%20Win32/Personal%20Builds/mingw-builds/installer/mingw-w64-install.exe/download) Right now the module is not directly integrated to be automatically built with the rest of the project. In order to build the C++ part, just change the directory into the “plc4cpp” directory and do a “mvn install” in there. I would be really happy for some feedback, as this stuff is a lot more complicated to configure than in my normal Java world. I hope I got everything right. So … then I’ll wish you all happy testing ;-) Chris
