Why is Qt reporting > 14000 errors in this one page source file?

Question

Here is the code:

#include <QtCore/QCoreApplication>
#include <QProcess>
#include <QProcessEnvironment>

int main(int argc, char *argv[])
{
    QProcessEnvironment env;

    // Environment variables required by CGI apps

    env.insert("QUERY_STRING",      url.encodedQuery());
    env.insert("REQUEST_URI",       url.toString());
    env.insert("REQUEST_METHOD",    "GET");
    env.insert("REMOTE_ADDR",       pSocket->peerAddress().toString());

    //==========

    QProcess process;
    process.setProcessEnvironment(env);
    process.start("php-cgi",QProcess::ReadWrite);

    process.write("<?php print_r($_GET); ?>");
    process.closeWriteChannel();

    process.waitForFinished();

    qDebug(process.readAll().data());

    return 0;
}

Qt Creator reports more than 14000 errors. Here is a small sample of them:

In file included from ../QProcess/main.cpp:2:
../QProcess/QProcess:1: error: stray ‘\177’ in program
../QProcess/QProcess:1: error: stray ‘\2’ in program
../QProcess/QProcess:1: error: stray ‘\1’ in program
../QProcess/QProcess:1: error: stray ‘\1’ in program
In file included from ../QProcess/main.cpp:2:
../QProcess/QProcess:1:8: warning: null character(s) ignored
../QProcess/QProcess:1: error: stray ‘\2’ in program

Answer 1

The problem was that I was including the wrong headers:

#include <QProcess>

...instead of...

#include <QtCore/QProcess>
