I'm sorry if it was mentioned before, but g++ 3.4.6/ 4.1.1/ 4.2.0-alpha20061031 don't compile this
<at math2-matrix-vector/src> g++-4.1.1 test.cc -I../include </at math2-matrix-vector/src>
<error message> ../include/math/bits/basic_matrix.h: In member function 'Type math::bits::basic_matrix<Rows, Cols, Type>::element() const': ../include/math/bits/basic_matrix.h:27: error: there are no arguments to 'data' that depend on a template parameter, so a declaration of 'data' must be available
[snip more error messages] Has it been that long since I tested this on gcc? Changing "data()" on the offending lines to "this->data()" should do it, though I'm afraid I can't guarantee there won't be other errors like it at the moment. Use -fpermissive as suggested if you want to try it out for now. Thanks. -- Daniel Wesslén
