Qt Linker Errors
- by Kyle Rozendo
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
Error 2 error LNK2019: unresolved external symbol "public: void __thiscall FileVisitor::processEntry(class QString)" (?processEntry@FileVisitor@@QAEXVQString@@@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.
