Error compiling: No viable overloaded '='

[Roberto Vergallo]

Hi,

I've downloaded and installed G3D 9.0 b03 on My MacOSX 10.7.

I've putted the G3D folder in my home directory, then I've set the PATH, G3D9DATA, LIB and INCLUDE variable in my .profile file ($LIB and $INCLUDE were not present).

I've trying to run the rawOpenGL sample in my XCode 4, but I get the following compile error in file Component.h: No viable overloaded '='

Can you help me solving the problem?

Thanks,

Roberto

The error refers to the following piece of code:

    static void convert(const Color4& c, Color1& v) {
         v = c.r; //the error is here
    }

Thanks.

Do this:

v = Color1(c.r)

or

v.value = c.r;

If float silently cast to Color1 it could lead to accidental type
errors elsewhere, so we disallow it.
