Hi there, we know the SDK and successfully worked with it to build and deploy some simple, some more sophisticated Snaps. Anyway - with strong background in computer science but only very little exprience in ARM development we faced (and solved) some hurdles during the development, which we think should be lowered to motivate future customers with a similar knowledge background to intensive use the platform to develop custom applications on ctrlX. Please do not take this as a criticism, we know the platform is under development - we only formulate a wish list. So: It would be very nice, if there was some kind of project template generator or template pool. If i want to start a new snap project, i have to choose: What do i want to have? Backend-App? Language (one of): Go Python C/C++ Anyway: There is an exemplary epp prepared which builds and runs directly Go: go build ctrlxsdk and ctrlxsdkgo-Wrapper downloaded as go-modules ./<projectname> [clientURL] [serverURL] → runs, prints "Hello World" and reads something from the DL Python: pipenv install gets the ctrlxsdk and ctrlxsdk-py-Wrapper as pipenv packages creates a working pipenv environment python main.py [clientURL] [serverURL] → runs, prints "Hello World" and reads something from the DL C/C++ CMake <projectname> ctrlxsdk downloaded / extracted automatically Compiles ./build/<projectname> [clientURL] [serverURL] → runs! Web-Application? If yes: The webapp and the backend have some exemplary code to connect a button and some input text field to a method in the backend app. The webapp contains the webcore template and compiles without any further modifications. npm install? Prepared Backbone in Go / Py (see above) Compiles / runs directly Provides access to Datalayer Browser localhost:8080 shows web app Exemplary call to backbone is implemented Development-Platform, Target Platform? Arm / x86 / amd64 For any combination there will be build scripts, so that compilation / cross compilation works without further modifications Alternatively: Just choose development platform and snapcraft automaticalls builds separate snaps for all relevant possible target architectures Build remotely? If cross compilation is hard to realize easily on the developers machines, it might be an option to offer some build environment in the form of some CI-pipeline on a rexroth hosted gitlab server. Lots of work, sure. We think if you really want to motivate non-rexroth and probably even non-classical-machine-builder developers to build ctrlX-apps for new use cases, the technical hurdle to get started has to be very low.
