gcc error: instantiated from...

vartas

Hi,
i got the following gcc-error and hope you could help me to unterstand why:

instantiated from 'const XWCPC* FILE_FM::LOCALE::fct_format(const xs_t*, xs_t*, FILE_FM::FB*, T, XWCP*) [with T = long double]'

Expand|Select|Wrap|Line Numbers

 
template<class T>

const XWCPC *fct_format(XS_CS ft, xs_t *buf, FB *o, T v, XWCP *r)

{    o->getFt(&ft);

    int l = LOCALE::xsPrintf1(buf, ft, v);

        ...

       return r;

};

Beats me. Nort enough code to see what's going on.

I did take your code and make some asumptions and did not get any error:

Expand|Select|Wrap|Line Numbers

 
typedef int XWCP;

typedef const int XWCPC;

typedef int XS_CS;

typedef int xs_t;

typedef int FB;

template<class T>

class LOCALE

{

public:

    int xsPrintf1(xs_t* buf, XS_CS ft, T v);

};

template<class T>

int LOCALE<T>::xsPrintf1(xs_t* buf, XS_CS ft, T v)

{

    return 0;

}

template<class T>

const XWCPC *fct_format(XS_CS ft, xs_t *buf, FB *o, T v, XWCP *r)

{   o->getFt(&ft);

    int l = LOCALE::xsPrintf1(buf, ft, v);

        ...

       return r;

};
 
int main()

{
 
   LOCALE<long double> obj;

   int a = 10;

   int b = 20;

   long double c = 3.5;

   obj.xsPrintf1(&a,b,c);

}

Thank you, weaknessforcats. This has already helped to locate the fault, but I am still 'overextend' with it. Here the code for the method:

Expand|Select|Wrap|Line Numbers

 
typedef wchar_t xs_ucs4_t;

typedef xs_ucs4_t xsu_t;

typedef xsu_t xs_t;

#define XS_(t) (t)

#define XS_CTC_(T) const T *const

#define XS_CUC XS_CTC_(xsu_t)

#define LOCALE_BUF_SIZE  255
 
template<class T>

static int xsPrintf1(xsu_t *b, XS_CUC f, T v)

{

    char bf[LOCALE_BUF_SIZE];

    char bv[LOCALE_BUF_SIZE];
 
    const xs_t *x = XS_(f);

    char *y = bf;
 
    for (int i = LOCALE_BUF_SIZE-1; i >= 0; i--)

    {

        if (!(*y++ = (char)(*x++)))

            break;

    }

    *y = 0;
 
    int r = snprintf(bv, LOCALE_BUF_SIZE,bf, v);
 
    y = bv;
 
    while (*b++ = (unsigned char)(*y++));
 
    return r;

}

thank you in advance for your help readiness.

Ok, thank you very much. Could it be a make-issue? In your code above, I received the following errors:
'template <class T> class LOCALE' used without template
parameters, line: int l = LOCALE: xsPrintf1 (buf, ft, v);
make: *** [main.o] .
