With such a tool one could stay with C and still be able to produce Java byte code for platform independent apps. Also, old programs (with some tweaking) could be re-compiled and ported to the JVM. We have been developing such a tool over the last 2 years and currently beta testing it. It's called MPC (for Multi-Platform C) and you can download the beta version at http://www.axiomsol.com or at http://freshmeat.net Napi Back to top Chris Barts Guest Posted: Fri Oct 15, 2004 8:21 am    Post subject: Re: C to Java Byte Code napi wrote: Quote: I think you would agree with me that a C compiler that directly produces Java Byte Code to be run on any JVM is something that is missing to software programmers so far.

NestedVM has a few other advantages as well; it's not restricted to C (we've used it on Fortran and Pascal programs as well) and it has no difficulties with compiler-specific quirks (gcc-specific or MSVC-specific hacks) since it doesn't try to replace the compiler. - a -- I wrote my own mail server and it still has a few bugs.

Currently MPC is in beta and we only support most of the ANSI C library which includes the file system management. The release version should support some UNIX system calls library, TCP/IP library, and graphics library. MPC is available to be used on Linux/x86 for now which produces code for the JVM. Next we will port it to MacOS followed by Solaris and then Windows XP/NT. Cheers.

You know, Mr. Abdullah, it would serve the truth better if you explained what your product cannot do, and if you tried to avoid a marked tendency to replace candor with marketing hype.

According to the evidence, this project won't actually convert most existing C programs into Java with a little "tweaking", as is claimed above. The project may eventually meet some of its claims, but it certainly does not now, and anyone contemplating involvement with this project should be very skeptical of the claims being made. Mr. Abdullah has repeatedly cross-posted messages that are pure marketing hype, then, when confronted by tough questions, replies with the defense that the product is in beta, without acknowledging that it very simply cannot meet the claims posted on the Web site. -- Paul Lutus http://www.arachnoid.com Back to top Gerry Quinn Guest Posted: Mon Oct 25, 2004 10:48 am    Post subject: Re: C to Java Byte Code In article <10npbpmkjaqdqa3 (AT) corp (DOT) supernews.com>, [email]nospam (AT) nosite (DOT) zzz[/email] says...
