What compiler to use when porting from linux

[erik]

Hi there,

I thought about giving the port of zapcvt a try.
Using djgpp I run into some libc limitations (memory mapped file io)
Anybody a suggestion on what compiler/libc I should use?

How about:

Microsoft Visual C++ Toolkit 2003

The Microsoft Visual C++ Toolkit 2003 includes the core tools developers need to compile and link C++-based applications for Windows and the .NET Common Language Runtime.

Thanks, I downloaded and will try.
In general I do not have a good experience with microsoft tools when porting from linux.
The libcs are often too different.
Any other suggestions?

FWIW, in my line of work, I write C++ code which must run on Windows, AIX, HP/UX, Solaris, DEC, & Linux. For Windows we do use the Visual Studio .NET 2003 (obviously without the managed code extensions) C++ compiler.

If I have some time tonight, I'll give it a go.

To be more specific, I need a C++ compiler with libc that suppors memory mapped file IO
That means, as far as I understood, it can map a file in memory so you use the virtual memory subsystem of windows to have quick access to any location in the file.
I need the functions mmap, munmap.

Well, I was happily porting using the .NET compiler when I ran into directly what you wrote -- an implementation of mmap/munmap (in the common folder).

I did find this, fwiw: http://66.102.7.104/search?q=cache:aXGL9...=firefox-a

...and they have an implementation near the bottom. I have no idea how well it works.

Oh -- here's probably an obvious question, but have you installed and tried the cygwin tools? You can google for that.

Or, something that I have played around a little at work is Microsoft's UNIX tools for Windows. Check it out here: http://www.microsoft.com/windowsserversy...fault.mspx

It will actually install a UNIXish subsystem on your PC (based on Interix) and allow you to compile unix code. May be worth a shot (and it's free now -- didn't used to be).

I tried cygwin. It compiles and builds so now I only have to do the hard work because the file created by zapcvt is currupt...
