linking errors when using templates

[murali]

Hi,

I get tollowing linking errors

Main.cpp:30 undefined reference to
Matrix<int>::Matrix[in-charge](int,int)

whats that '[in-charge]' and what might be the problem ??

line 30 of main: Matrix<int>::Matrix(array,int rows,int cols)

and the matching (supposed to be) constructor is
Matrix<T>::Matrix(const T *array,int rows,int cols)

even for the default constructor call I get the same linking error

I'am driven to edge of sanity... plz help


Thanks,

For the sake of your sanity, you should have tried

1) searching this newsgroup or
2) reading the FAQ.

This question gets asked several times a month. The answer is always the
same.

Put all the template code in the header file.
