While I think the generated C-Code should probably be compilable for
other platforms the problem that you can not solve without Wolfram is
that you will need to link to the Wolfram RTL library (that's the
"Libraries" -> "WolframRTL_Static_Minimal.lib" part in
CCodeGenerator/tutorial/Examples#119837896). AFAIK Android and Palm's
WebOS are basically Linux-Distributions but since they typically running
on ARM processors you can not use the (binary) libraries that come with
the Linux version of Mathematica (which I think is only available for
the x86/x64 architectures). For the iPhone I'm not even sure if there
are C-Compilers and standard libraries available (officially), I think
Apple insisted on apps to be programmed in Objective C until very
recently...

As long as Wolfram Research does not provide the Wolfram RTL libraries
for these architectures, you are out of luck. Does anyone know whether
binaries for these architecture are available or planned to be made
available or did I get something wrong with the above?

hth,

albert
