HW#1 Prob 4 may fail to compile in some versions of Linux (e.g. RedHat
Enterprise 3.0). You may see the following error message:
========
g++ -c -o circuit.o circuit.cpp
In file included from bddManager.h:12,
from circuit.h:15,
from circuit.cpp:14:
bddHash.h: In member function `void BddHash::deleteNodeInt()':
bddHash.h:55: invalid use of undefined type `struct BddNodeInt'
bddHash.h:16: forward declaration of `struct BddNodeInt'
make: *** [circuit.o] Error 1
========
This is because the function "deleteNodeInt()" tries to call "delete
BddNodeInt", where file "bddNode.h" is not included (intended so).
You can fix this by:
==============
in "bddHash.h"
==============
52 #if 1
53 void deleteNodeInt();
54 #else
55 void deleteNodeInt(){
56 for ( int i = 0 ; i < _numBuckets; i++)
57 for ( int j = 0; j < _buckets[i].size(); j++)
58 delete _buckets[i][j]._node;}
59 #endif

line number
That is, don't define the function "deleteNodeInt()" inside "bddHash.h".
Instead, find a .cpp file, for example, "bddManager.cpp", insert this at the
end:
=================
in "bddManager.h"
=================
336
337 void
338 BddHash::deleteNodeInt()
339 {
340 for ( int i = 0 ; i < _numBuckets; i++)
341 for ( int j = 0; j < _buckets[i].size(); j++)
342 delete _buckets[i][j]._node;
343 }
The problem should be fixed!!
