O List, here is my plea for help Could somebody from Wolfram please have a complete and better example in the examples folder for C/C++ communication for the next release? And they can blog about it today on the Wolfram blog! addtwo/factor/quotient etc are so simple yet not completely practical. I will use addtwo() and figure out stuff slowly starting with hard coding stuff and using dummy input & dummy output. Or use this page directly for now using commandline programs http://reference.wolfram.com/mathematica/tutorial/IntroductionToMathLink.html. Here's my scenario which could be a typical example: Using Mathematica for prototyping. I will call C program stubs like addtwo which actually call command line executable inside that addtwo() which has templated C++ code for proven and tested code which is not available in Mathematica (and probably won't be soon). Have this complete with error checking (CTRL + C) and any other issues you experienced folks might know. This example will include the manual keyword, use MLGet* and MLPut* functions appropriately, show how to pass strings, array, int, float, long etc as a argument. I know, I know the information is all there currently but it is scattered! We want one file to rule them all. Reading docs and searching around is fine but newbies would want quick turnaround. Can't somebody help speed up this tedious process? The Java page http://reference.wolfram.com/mathematica/howto/ConnectAJavaProgramToMathematica.html makes it look so easy (it might not be as I haven't delved into it). ------------------------------------------------------------------------------------------------------------------------------------ To Wolfram Documentation team IMHO, as a total beginner and a newcomer the instructions for building under newer releases of Windows Visual Studio on C/C++ side are not mentioned in quite a few releases. Concrete examples 1) minor nit: The documentation on the Wolfram website for setting up the Visual Studio is here http://reference.wolfram.com/mathematica/tutorial/MathLinkDeveloperGuide-Windows.html#26660 The latest supported is Visual Studio 2008 (version 9) with Visual Studio 2010 just round corner. Is it possible to have the Mathematica installer figure out and put the files in the proper place? Or ask during installation, do you intend to use mathlink and installer will setup the paths? Thanks in advance for your time.
