you can forward declare the map here, and include this header in .cc file

[sujith, 2017/06/21 13:04:59]

are you suggesting to do a declaration like this

namespace cc {
using BufferToTextureTargetKey = std::pair<gfx::BufferUsage, gfx::BufferFormat>;
using BufferToTextureTargetMap = std::map<BufferToTextureTargetKey, uint32_t>;
}

[boliu, 2017/06/21 16:01:25]

I meant this:

namespace cc {
class BufferToTextureTargetMap;
}

If that doesn't work, then include here is fine.

its not working since BufferToTextureTargetMap is not a class, its just a map
object.
