Question

I have a class with the public function in a dynamic library:

void setActiveAnimation(std::shared_ptr<MaJR::Animation> anim);

and when I attempt to call it like so:

    MaJR::Actor actor;
    actor.setActiveAnimation(idleAnimation);

I get the following:

/home/mike/NixCraft/main.cpp||In function 'int main()':|
/home/mike/NixCraft/main.cpp|12|error: no matching function for call to 'MaJR::Actor::setActiveAnimation(MaJR::Animation&)'|
/home/mike/NixCraft/main.cpp|12|note: candidate is:|
/usr/include/MaJR/Actor.hpp|16|note: void MaJR::Actor::setActiveAnimation(std::shared_ptr<MaJR::Animation>)|
/usr/include/MaJR/Actor.hpp|16|note:   no known conversion for argument 1 from 'MaJR::Animation' to 'std::shared_ptr<MaJR::Animation>'|
||=== Build finished: 4 errors, 0 warnings ===|

What should I do?

Answer 1

The error clearly states that you are trying to call the function with a reference to MaJR::Animation instead of a std::shared_ptr<MaJR::Animation>. Whenever you declare idleAnimation you should have instead:

std::shared_ptr<MaJR::Animation> idleAnimation( new MaJR::Animation() );

or better yet:

std::shared_ptr<MaJR::Animation> idleAnimation = std::make_shared<MaJR::Animation>();
