Hi All,

I've been trying to get Qt working (QCreator, QIde and now VS2008).

I have sorted out a ton of issues already, but I am now faced with the following build errors, and frankly I'm out of ideas.

Error   1   error LNK2019: unresolved external symbol "public: void __thiscall FileVisitor::processFileList(class QStringList)" (?processFileList@FileVisitor@@QAEXVQStringList@@@Z) referenced in function _main   codevisitor-test.obj    Question1

The code is as follows:

#include "argumentlist.h"
#include <codevisitor.h>
#include <QDebug>

void usage(QString appname) {
    qDebug() << appname << " Usage: \n"
         << "codevisitor [-r] [-d startdir] [-f filter] [file-list]\n"
         << "\t-r        \tvisitor will recurse into subdirs\n"
         << "\t-d startdir\tspecifies starting directory\n"
         << "\t-f filter\tfilename filter to restrict visits\n"
         << "\toptional list of files to be visited";
}

int main(int argc, char** argv) {
    ArgumentList al(argc, argv);
    QString appname = al.takeFirst(); /* app name is always first in the list. */
    if (al.count() == 0) {
        usage(appname);
        exit(1);
    }
    bool recursive(al.getSwitch("-r"));
    QString startdir(al.getSwitchArg("-d"));
    QString filter(al.getSwitchArg("-f"));
    CodeVisitor cvis(filter, recursive);
    if (startdir != QString()) {
        cvis.processEntry(startdir);
    }
    else if (al.size()) {
        cvis.processFileList(al);
    }
    else
        return 1;
    qDebug() << "Files Processed: %d" << cvis.getNumFiles();
    qDebug() << cvis.getResultString();
    return 0;
}

Thanks in advance, I'm simply stumped.
