Hello all,

I am trying to follow the example given in 19.3.2 but I am having some trouble. I believe the problem lies in the positioning of my code.

In the fred_singular.h file, I have this layout,

template <class Q>
struct Wwghts {

......

};

struct Quad_matrix {

......

};

Then I have the main function in a .cpp file.

When I try to compile the code I get 5 errors.

The first is a syntax error '{' but all of the bracing is correct.

The second is "unexpected token(s) preceeding '{' skipping apparent function body.

The third is "weights" : is not a member of 'Wwghts<Q>'

Do I just having something in the code out of sequence?

NOTE: All of this code is copyrighted so I can't really post a nice example showing the functions.

Any help would be greatly appreciated.

Thanks
Matt

The file fred_singular.h is arranged like this:

template <class Q>
struct Wwghts {
.
.
.
}; // Make sure you have the semicolon to close the struct definition
struct Quad_matrix {
.
.
.
}; // Make sure you have the semicolon to close the struct definition
Int main_fredex(void)
{
.
.
.
}

Thanks Dave,

I just had some stuff out of order and one typo.

I created a seperate .cpp file and moved the main_fredex inside that file. Once I put everything in one header file, the problems where corrected.

I have the same results that you posted above.

Thanks
Matt
