I am trying to cast a fixed size array to another type in a templated function and I am getting an error.

Code: Select all

template<int n>
int fcn()
{
    Array<int,n,1> a;
    a.cast<float>();
    return 0;
}


This generates the following error.

Code: Select all

||=== Build: Debug in trial (compiler: GNU GCC Compiler) ===|
C:\Users\redwards\workspace\trial\main.cpp||In function 'int fcn()':|
C:\Users\redwards\workspace\trial\main.cpp|95|error: expected primary-expression before 'float'|
C:\Users\redwards\workspace\trial\main.cpp|95|error: expected ';' before 'float'|
C:\Users\redwards\workspace\trial\main.cpp||In instantiation of 'Split<nports>::Split(const Eigen::Array<double, 2, 1>&, const Eigen::Array<double, (nports - 1), 1>&, const Eigen::Array<unsigned int, nports, 1>&, ftype, ftype) [with unsigned int nports = 2u; ftype = double]':|
C:\Users\redwards\workspace\trial\main.cpp|112|required from here|


if I comment out the line

Code: Select all

template<int n>
int fcn()
{
    Array<int,n,1> a;
//    a.cast<float>();
    return 0;
}


then it compiles fine. With dynamic sized arrays it compiles fine. Any insight would be greatly appreciated.
