I'm building my first program with dub. It appears I can import and use a struct from a "library". But the template struct is undefined unless I change the target type to "sourceLibrary".

The sources are like this:

// library ////////////////
// shapes.d
module core.shapes;

struct triangle
{
}

// math.d
module core.math;
import std.stdio;
struct MATRIX(T, int R, int C)
{
}

// package.d

module core;

public
{
    import core.math;
    import core.shapes;
}
/////////////

// executable //////////////////

import std.stdio;
import core.math;
import core.shapes;
int main(string[] argv)
{
    triangle t;
    MATRIX!(float, 4, 4) a;
    writeln(t);
    return 0;
}

// dub.sdl
targetType "none"
dependency ":example" version="*"

subPackage {
    name "core"
    targetType "library"
    sourcePaths "core"
    importPaths "."
}

subPackage {
    name "example"
    targetType "executable"
    sourceFiles "example/main.d"
    importPaths "example"
    dependency "proj:core" version="*"
}

I get Error: template instance MATRIX!(float, 4, 4) template MATRIX is not defined

What am I doing wrong here?

Never mind. I had wrong module paths.
