[-fpermissive] ???

[levan]

Hello

I am trying just to create a vector object in my executable .cpp like this :

Ogre::Vector3 transVector = Ogre::Vector3::Vector3(1,1,1);


and getting following errors during the compilation.

error: cannot call constructor 'Ogre::Vector3::Vector3' directly [-fpermissive]

error: for a function-style cast, remove the redundant '::Vector3' [-fpermissive]

can you please tell me what is wrong there.

Ogre::Vector3 transVector = Ogre::Vector3(1,1,1);

Or even simpler:

Ogre::Vector3 transVector (1,1,1);

Second option is better. The first one creates a temporary vector3 and then calls a copy constructor, which is unnecessary.

The compiler will usually optimize that away. See Copy elision.
So use whatever you find easier to read.
