Re: New User and how to use octave in c code ?

[Progressive]

I tried now
https://www.daniweb.com/programming/software-development/threads/297336/gnu-octave-for-c-how-to-start

and removed in all lines in octave.h the "OCTINTERP_API"

Now I gain different errors :) By using #include <octave.h> I get

> error: ‘Matrix’ was not declared in this scope
>  Matrix a_matrix = Matrix (n, n);
>  ^
>embedded.cpp:10:9: error: expected ‘;’ before ‘a_matrix’
>  Matrix a_matrix = Matrix (n, n);

and by using #include <oct.h> I get

> In function `Array<double>::Array(dim_vector const&)':
> /usr/include/octave-4.0.2/octave/Array.h:176: undefined reference to
> `dim_vector::safe_numel() const'

is this complete nonsense or something to work on ?
embedded.o:(.data.rel.ro._ZTV6Matrix[_ZTV6Matrix]+0x20): undefined reference
to `Array<double>::resize_fill_value() const'
collect2: error: ld returned 1 exit status
