[Martenlist] Anyone using Marten for generating C code for embedded systems

[Pekka Nikander]

Hi Luis,

Thanks, I tried.  XCode doesn't seem to be needed.  GCC is enough.  I  
have the cross-compilation environment already fine and working, so  
that is not a problem at all.

The bigger problem appears to be the Marten runtime library, /Library/ 
Frameworks/MartenStandard.framework/MartenStandard.  That seems to  
implement a runtime that implements functions such as the following:
   VPLEnvironmentCreate("CommandLine", kvpl_StackInline, kFALSE);
   load_Standard(environment);
   vpx_method_map(environment,kVPXMethod_Command_20_Line,"Command  
Line");
   VPLEnvironmentInit(gVPLCommandLine_Environment, vpl_INIT);
   VPLEnvironmentMain(gVPLCommandLine_Environment, vpl_MAIN, argc,  
argv);
   method_new("Command Line", environment);
   vpx_method_initialize 
(environment,result,vpx_method_Command_20_Line,"MAIN");
   etc etc etc

Re-implementing them for the embedded platform won't be that easy.   
In other words, the generated C code seems to be, based on its  
initial appearance, far from self-contained.

Hmm.  Is the runtime documented somewhere?
