Hi I started a thread earlier back and I thought my problem had been solved but now new errors have popped up

Here are the errors I'm getting:

bfs.cc: In function 'void greedyMatch()':

bfs.cc:9: error: expected primary-expression before 'for'

bfs.cc:9: error: expected `)' before 'for'

bfs.cc:9: error: 'bfs_ee' was not declared in this scope

bfs.cc:9: error: 'bfs_stopA' was not declared in this scope

bfs.cc:9: error: expected `;' before ')' token

bfs_run.cc:83: error: expected `}' at end of input

The file bfs.cc is as follows:

```
#include <math.h>
void greedyMatch()
{
Xnode *u;
Ynode *v;
arc *e;
forallXNodes(u,G) {
assert(!u->isMatched());
forallOutArcs(e,u) {
#ifdef STATS
stats.searchArcCnt++;
#endif
v = e->head();
if (!v->isMatched()) {
#ifdef STATS
stats.mVal++;
stats.greedCnt++;
stats.flowArcCnt++;
#endif
v->match(u);
u->match(v);
break;
}
}
}
}
void augment(Ynode *last)
{
Ynode *v, *v1;
Xnode *w;
arc *e;
v = last;
do
{
w = v->getCurrent();
#ifdef STATS
stats.flowArcCnt++;
stats.searchArcCnt++;
#endif
v->match(w);
if (w->isMatched())
{
v1 = w->getMatchNode();
assert(v != v1);
w->match(v);
v = v1;
}
else
{
w->match(v);
break;
}
}
while (1);
#ifdef STATS

#endif
}
void bfsBIM(simpleQueue &Q, simpleQueue &S)
{
Xnode *u, *w;
Ynode *v;
arc *e;
bool foundPath;
forallYNodes(v,G)
{
v->initialize();
#ifdef STATS
stats.searchArcCnt++;
#endif
}
forallXNodes(u,G)
{
u->initialize();
u->setReached(false);
#ifdef STATS
stats.searchArcCnt++;
#endif
}
if (param.greedy) greedyMatch();
forallXNodes(u,G)
{
#ifdef STATS
stats.searchArcCnt++;
#endif
if (u->isMatched() || u->isReached()) continue;
// start BFS from u
foundPath = false;
u->setReached(true);
Q.enqueue(u);
S.enqueue(u);
do
{
u = Q.dequeue();
forallOutArcs(e,u)
{
#ifdef STATS
stats.searchArcCnt++;
#endif
v = e->head();
if (v == G.getSource()) continue;
if (v->isMatched())
{
w = v->getMatchNode();
if (w->isReached()) continue; // includes w == u
assert(w != u);
v->setCurrent(u);
w->setReached(true);
Q.enqueue(w);
S.enqueue(w);
}
else
{
foundPath = true;
v->setCurrent(u);
augment(v);
break;
}
}
} while (!foundPath && !Q.isEmpty());
// get ready to start new search
Q.reinitialize();
if (!foundPath)
S.reinitialize(); //reached vertices remaine marked
else
{
// clean up
while (!S.isEmpty())
{
u = S.pop();
assert(u->isMatched());
u->setReached(false);
}
}
}
}
```

The forallXnodes has been #defined in another file.This new file is visible in bfs.cc due to dependencies created by the make file .

```
#define forallXNodes(u,G) \
(for( arc *bfs_ee=(G.getSource())->firstOutArc(),arc *bfs_stopA=\
(G.getSource())->lastOutArc(),u=bfs_ee->head();bfs_ee<=bfs_stopA;u =\
(++bfs_ee)->head()))
```

Any help shall be appreciated.......

I am using GNU g++ compiler.

Thanks,guys.
