Tim, c/c++ folks,

I have worked gcc47 patches in most of the major packages to the point where I have hit a common failure that I cannot solve. The common problem involves error: redeclaration of (foo). Usually involving some iterator. The list of packages that have a similar build failure are:

tde-kipi-plugins - error: redeclaration of 'TQListViewItemIterator it'

tde-tdepim - error: redeclaration of 'TQMap<TQGuardedPtr<KMFolder>, int>::Iterator it'

tde-k3b - error: redeclaration of 'K3bAudioEditorWidget::Range* r'

rosegarden - error: redeclaration of 'std::multiset<Rosegarden::Event*

I don't know what the various declarations are supposed to look like to begin with so I sure can't recognize which one, and in what scope, the declarations need to be fixed. Thanks for you help.

Here is the code-block from rosegarden that is failing in src/document/RosegardenGUIDoc.cpp (line 2147 and 2152 designated with '*'):

* for (RecordingSegmentMap::iterator i = m_recordMIDISegments.begin(); i != m_recordMIDISegments.end(); ++i) {

Segment *s = i->second; * Segment::iterator i = s->begin();

if (i == s->end() || !(*i)->isa(Clef::EventType)) continue;

if ((*i)->getAbsoluteTime() < meaningfulBarStart) { Event *e = new Event(**i, meaningfulBarStart); s->erase(i); s->insert(e); }

I see the designations:

(1) RecordingSegmentMap::iterator i = m_recordMIDISegments.begin() (2) Segment::iterator i = s->begin();

How is the compiler seeing ' RecordingSegmentMap::' and 'Segment::' as the same thing?

More importantly, how to fix it?

This is all withing the scope of:

2087 void 2088 RosegardenGUIDoc::stopRecordingMidi() 2089 { ... 2229 }

Grepping it looks like it is declared a number of times:

archangel:/dat_e/tmp/rosegarden/src/document> grep -En 'Segment[A-Za-z]*::' RosegardenGUIDoc.cpp <snip> 2099: std::vectorRecordingSegmentMap::iterator toErase; 2101: for (RecordingSegmentMap::iterator i = m_recordMIDISegments.begin(); 2109: for (Segment::iterator i = s->begin(); i != s->end(); ++i) { 2147: for (RecordingSegmentMap::iterator i = m_recordMIDISegments.begin(); 2152: Segment::iterator i = s->begin(); 2592: (Segment::Audio); 2710: for (RecordingSegmentMap::iterator ri = m_recordAudioSegments.begin();

What to do?
