hi,

has anyone used WxWindows with the digital mars compiler?
If so is there a list of steps / patches to enable the wxwin library &
applications to be built.

I have been experimenting with building the wxWindows library using the makefiles supplied with wxWindows. Progress so far:

1 modified '\include\wx\defs.h' to recognise digital mars instead of
symantec
this at least allows compilation to begin.

2 sc complained about duplicate member function definitions in Icon.h. The problem was the following member functions from class Icon

    wxIcon(const char **data) { CreateIconFromXpm(data); }
    wxIcon(char **data) { CreateIconFromXpm((const char **)data); }

It appears that sc sees 'const char**' and 'char**' as the same. This
seems a bit strange.
As a test I created a small project with the IDDE, a code snippet is
below:

void    func1( char* d) {}
void    func1( const char* d) {}

void    func1( char** d) {}
void    func1( const char** d) {}

class   XX
{
public:
    void    func1( char* d) {}
    void    func1( const char* d) {}

    void    func1( char** d) {}
    void    func1( const char** d) {}
};

The compiler produces the following output:

sc ..\test1.cpp -mn -C -WA -S -3 -a8 -c -gf -D_CONSOLE=1 -o..\test1.obj
Error: H:\Digital_Mars\test1\DmW32\..\test1.cpp(10): 'func1' previously
declared as something else
H:\Digital_Mars\test1\DmW32\..\test1.cpp(10): It was declared as: void C
func(char **)
H:\Digital_Mars\test1\DmW32\..\test1.cpp(10): It is now declared: void C
func(char const **)
Error: H:\Digital_Mars\test1\DmW32\..\test1.cpp(19): 'XX::func1' is
already defined
Lines Processed: 10525  Errors: 2  Warnings: 0
Build failed

It appears that the compiler considers the functions with 'ptr to ptr' parameters as being "C" functions. I can get around this by commenting out one of the functions, but I would rather not unless I have no choice.

Is this a known issue or am I missing something obvious?

BTW I am very new to digital mars, (mainly worked with Watcom & MSC over
last few years).

I'll look into it. -Walter
