- clone asmjit (https://github.com/area9innovation/asmjit.git) into platforms/common/cpp folder first (eventually we'll move to upstream asmjit, we use our copy of this lib yet);
- make sure you have Qt 5.12.0 (or upper) available in your system;
- review paths in QtByteRunner.pro, they're usually fit our needs, but in some cases may require changes;
- run build.sh, it'll produce binary for your system.
Then you'll be able to run flowcpp tool.
- you run flowcpp and feed it with .flow file;
- flowcpp see that it is source file and calls compiler
- compiler produces .bytecode file
- flowcpp executes .bytecode file and runs file you called.
You can call compiler directly with flowc or flowc1 commands.
