Connecting rooms with halls

vastrolorde (178)
I used BSP algorithm to split my map into subsections. Each subsections has 1 room inside.

I cant figure out how to connect all these rooms. Currently i have randomly selected rooms and then hallway made between them, but this creates a problem where there can be 3 or more halls side by side and halls that connect 2 rooms goes through other rooms.

I removed some of the repetition by checking current connections between rooms, but this doesent solve all the problems.(only 1 level deep, if i go deeper i get stack overflow)

http://tinypic.com/r/jhq7tg/8 current output. Some boxes are hard to see because colors are also randomly generated.

Instead of generating halls between two random rooms try to select one room and determine candidates: closest fooms in each cardinal directiron.

Or reject passage in it intersects another room

I found another solution for the problem. But i think i have gotten something wrong.

I wrote a code that just goes over the hallway vector and removes any vector where 2 are next to each other, shorter one will be removed. But now i get unreachable rooms.

I think i have gotten something wrong or some idea wrong.

X1 and Y1 is hte starting point and X2 and Y2 is the ending point of a hall.
If i need a 90degree hall i just crate 2 halls one horisontal, 1 vertical.

for (std::vector<Hall*>::iterator it = halls.begin(); it != halls.end();){
		for (std::vector<Hall*>::iterator it2 = halls.begin(); it2 != halls.end();){
			bool erase = false;
			if (it != it2){
				if ((*it)->getHeight() != 1 && (*it2)->getHeight() != 1){
					if ((*it)->getX1() + 1 == (*it2)->getX1() || (*it)->getX1() - 1 == (*it2)->getX1()){
						it2 = halls.erase(it2);
						erase = true;
					}
				}
				if ((*it)->getWidth() != 1 || (*it2)->getWidth() != 1){
					if ((*it)->getY1() + 1 == (*it2)->getY1() || (*it)->getY1() - 1 == (*it2)->getY1()){
						it2 = halls.erase(it2);
						erase = true;
					}
					
				}
			}
			if(!erase){
				++it2;
			}
		}
		++it;
	}
