Very Computer

Pardon the very newbie-type questions;

Is it possible to use KDevelop to compile Wine?

Is it possible to use KDevelop to compile Windows-less native Wine
applications? ie meaning Windows apps that you would compile totally with
the Wine development kit (GCC and the Wine .H and .LIB files)?

Is it possible to use KDevelop (or Wine itself for that matter) to develop
MFC applications under Linux using GCC as a compiler? I suppose I'm asking
if the MFC headers are all there or can be copied over and used by the GCC
compiler. Will the GCC compiler emit the proper name-mangling for C++ code?
Can GCC do C++ code at all?

If a Wine-driven Windows app crashes, can it take down the Linux kernel? I
mean -god forbid- that there would be bugs in the Wine kernel code, how
deeply is this thing plugged into Linux? Deep enough so that a Windows app
could crash everything?

Please don't flame me, as I am rather ignorant and I am only seeking to
understand.

Thank you.

KDevelop is a text based editor that can write in any language you want.  
It is not a compiler, it is an IDE.  GCC is the GNU compiler collection and
it will do C++ if you use its g++ compiler.  Wine (is not an emulator) is
a program that runs and returns either success or failure to the kernel.  
Assuming it cannot lockup a display or hold some essential resource
hostage, it will not crash the kernel.  I don't think Wine has a "kernel"
in the sense that it is not an operating system.  It is, at best, a virtual
machine that mitigates between the kernel and a windows program.  None of
these questions have anything to do with the K Desktop Environment.  They
belong to the Wine newsgroup you cross posted to, and the forum or
mailinglist found at www.kdevelop.org.

Thanks so much for your answer, Gregory.

I looked for a newsgroup that could answer questions for KDevelop, but
judging from your answer, none exists. I will consult the KDevelop mailing
list instead.

Oh well, you may have cleared things up a little anyway, so thank you again.

I think the best explination for what wine does is its an executable
loader, much like what the kernel does for elf file wine does for PEF
files, it also has a collection of dll's that are the win32 api.

since the license for MFC is a bit odd, you'll have to read it to be sure
if you can link it using other compilers on non MS OS's

Sure, if you have the source code and don't use any Windows stuff that Wine
doesn't (yet) implement.

No, I don't think so. But even if you could, you would need a Microsoft
license for Visual C++ (with which MFC is included) so you would be better
off using Visual C++, as it was designed to work with MFC from the ground
up.

For a very similar cross platform compiler and language to VC++, look at
www.wxwindows.org. The classes are very similar to MFC. I have not used
it, but read through some of the docs and sample source code.

I occasionally use VC++ on W98. The similarities are "striking".

Thank you Ron Ginsberg, and thank you Jack Portier.

Here's the crux of my problem:

I am developing an application written in MFC.
It also includes some open-source GPL code too.

So far, no problem. The Visual C++ 6.0 development environment's licensing
doesn't forbid me from doing anything except redistributing code written by
Microsoft, which I will not do anyway, because it is a commercial
application I am developing.

My problem arises here:

    Because I am using some of Microsoft's advanced common controls that
normally ship with Internet Explorer 5.x, I have had to download the
Microsoft Platform SDK to "freshen" my header files.

    The constants necessary to use the new controls are in the updated
header files in the MS Platform SDK.

    The hitch is that the (newer) license for the MS Platform SDK seems to
be forbidding me from using open source source code in my application!!!

    I'm not a lawyer, so I'm not absolutely sure if I've understood the
licensing properly, but if that IS the case, I have to completely move my
application development from Microsoft tools to open source tools.

I've included the relevant part of the MS Platform SDK licensing agreement,
if anyone wants to have a go at interpreting it, please do.

1) Gcc certainly can do C++. It is also more ANSII compliant then VC++.
   Namespaces, STL, safe casts, all the rules about "const", all is there.
2) Wine runs in unprivileged mode, as a normal user and it cannot take
   your machine down. It can hang your screen, though, so that you have to
   get into the machine using some workaround (in my case, it's another PC
   on the same ethernet) and kill the process yourself.
3) I've never been a great fan of Microsoft, so I cannot answer your
   Kdevelop questions, but there is a commercial product which can be
   found at: http://www.bristol.com/windu/index.html
4) Using Microsoft products does bad things to lambs and chicken and might
   bring the anger of unspeakably evil things upon you. It also spoils
   milk.

not to mention there is no such thing as "proper" name-mangling, part of
the problem w/ inter compiler workings.

Mladen,

    Thank you.

    What you wrote is really interesting: The fact that Wine runs as an
unprivileged task is great! Linux might make a better Windows than Windows!

    Thanks again.
