Question

First off, my code compiles and runs fine on Mac OS X with compiler

i686-apple-darwin11-llvm-g++-4.2 (GCC) 4.2.1

but on Ubuntu with compiler

g++ (Ubuntu/Linaro 4.6.3-1ubuntu5) 4.6.3

it won’t compile.

In my header I have

std::vector<Obstacle::Obstacle*> obstacles;

which gives the following compilation error in Ubuntu:

error: ‘Obstacle::Obstacle’ cannot appear in a constant-expression

Any ideas of what I need to change to make it work?
Is there some magical compile flag I should use on Ubuntu to make it work just as on OS X?

Thank you

EDIT: Obstacle is a class.

Answer 1

You cannot pass constructor pointer as stored type.

Instead of

std::vector<Obstacle::Obstacle*> obstacles;

try

std::vector<Obstacle*> obstacles;
