Porting To Win32!!!!


I'm trying to port my program over to windows using visual c++ express as my compiler. Why I really don't know, I guess to allow my friends (who won't try Linux for nothing) to test and use it. I want it to be capable of being built on either system. I've ran into a couple of problems and was seeking some help.

1.) Windows doesn't use file permission, well at least to my knowledge and I have all these errors.
"error C2065: 'F_OK' : undeclared identifier"
"error C2065: 'mode_t' : undeclared identifier"
etc... I know that I will have to find a way to 'by pass' these permission sections in my code, but how. I know that windows compilers define a preprocessor directive WIN32, so I could use something similar to this to test if it is being built on windows.
#ifdef WIN32
....
#endif
I know that I could include different files this way (that don't include these permissions, but that would be a LOT of work. Is there any shortcuts to this?

2.) I also have a couple functions that test if a path points to a file or a directory. Here's a sample:
Code:
#include <sys/types.h>
#include <sys/stat.h>
#include <dirent.h>

using namespace std;

bool isdirectory(string path)
{
    bool test = false;
    struct stat stats;
    if (!stat(path.c_str(), &stats)) {
        if (S_ISDIR(stats.st_mode)) {
            test = true;
        }
    }
    return test;
}

bool isfile(string path)
{
    bool test = false;
    struct stat stats;
    if (!stat(path.c_str(), &stats)) {
        if (S_ISREG(stats.st_mode)) {
            test = true;
        }
    }
    return test;
}
But this results in these errors:
"error C3861: 'S_ISDIR': identifier not found"
"error C3861: 'S_ISREG': identifier not found"
Is there a different way to preform these test under win32?

THANKS in advance!!!

Hey, Windows Is Not Unix (or POSIX as they say).
Try compiling with Cygwin, Mingw32, or use ANSI C and #ifdef's to use pure Win32 code.

ok....?
I tried using cygwin, but I couldn't get it to find all of my include files, such as gtk, glib, id3, etc...
In visual c++ you can specify all of the directories to search. (really snappy)

So I have somewhat of a solution to 1.), but what about 2.)?

OK...
I've fixed all of my problems (the long way), except for question 2. How would I go about testing if a path points to a file or a directory in win? I've googled for about an hour and can't seem to find a solution.

Thanks...

Try with these defines:

Code:
#ifndef S_ISDIR
#define S_ISDIR(mode)  (((mode) & S_IFMT) == S_IFDIR)
#endif

#ifndef S_ISREG
#define S_ISREG(mode)  (((mode) & S_IFMT) == S_IFREG)
#endif
if your compiler gives errors to these, then the whole stat() stuff can't be done the Unix way.

Seriously ?

Huh, I thought that no system with S_ISDIR() had S_IFDIR though some packages redefine these when the configure script detected them to be broken with the "STAT_MACROS_BROKEN" macro.

Can you post <sys/stat.h> here ? (with copyright notices included )

Thanks for all of the replies, I did get it to 'compile' on visual c++, but I can't seem to build a solution to the project. I'm not really familier with this software and I don't understand what the differerence is in compiling and building a solution, but I get a whole bunch of link errors when attempting to build. I googled around and tried a few different things, but I was unsuccessful at finding a solution to the problem. I'm really busy with school at this time, so I'm just gonna put this off for a while and continue it when I have more time to learn how to use the visual c++ software.

Thanks Again,
Bendeco
