Code generation for C compilers #240

Closed imberium closed 5 years ago

imberium commented 5 years ago

Hi, I am trying to generate some C or Arduino code from the following ThingML code, but I am getting the error below, I don't know what is missing, everything seems correct, it generates code for the other languages though like Java or ReactJS :

thing Hello
{   
    statechart HelloBehavior init setup {

         state setup 
         @ignore "sink"
         {
            on entry 
            do 
                print "Hello"
            end
            }

        }
}

configuration helloCfg
{
    instance hello:Hello
}
Please contact the ThingML development team (though GitHub's issue tracker) with 1) your input model, and 2) the following stack trace:

I cannot reproduce this issue. Can you give more details about your setup (OS, Eclipse Version, ThingML plugins version, etc)

imberium commented 5 years ago

Here is my configuration ThingML 2.0.0.201807050918 Maven 3.5.3 Java 1.8.0_151, vendor: Oracle Corporation Default locale: en_US, platform encoding: UTF-8 OS name: "linux", version: "4.15.0-24-generic", arch: "amd64", family: "unix" I use Eclipse Photon, but I remember having the same problem with Oxygen

However, everything works fine when I use the CLI version from the repo. Maybe the released version need to be updated
