I noticed on a freshmeat.net <http://freshmeat.net> announcement that there is a program called Cibyl that converters MIPS binaries into Java bytecode.
A closer look at Cibyl <http://code.google.com/p/cibyl/wiki/Cibyl> is not very encouraging, WRT FPC/Lazarus compatibility :-(
Since only C code can be converted, what IMO is a reasonable restriction (as I made for ToPas), this would mean that only subroutines can be converted, not classes and methods. This will apply to all such converters.
The sample code in above article suggest that a dedicated GUI interface #include <javax/microedition/lcdui.h> has to be used, and most probably also a Java related RTL.
This means that a convertable FPC/Lazarus application can *not* use the classes and components in FCL or LCL, it must not use classes at all :-(
I wonder if using the fpc cross-compiler to mips-32 would allow FPC/Lazarus to leverage the converter in Cibyl to accomplish the same thing, but for FPC instead of C/C++.
This may work, but only for non-OO code. Since the LCL is based on classes, no Cibyl/Java widgetset can be created and used in convertable code.
It would be easier[1] to add a Java target to FPC itself, and to make it use Java libraries instead of .dll or .so libraries. The language also would deserve modifications, because the built-in strings and other types must be replaced by the native Java types (using UTF-8). An application consequently would look more like Java code, with Pascal syntax only in statements.
[1] Where "easier" still means that this would be such a big task, that nobody honestly would ever implement a Java or .NET target for FPC.
