[Qt-embedded-interest] Error 301 (QNetworkReply::ProtocolUnknownError) for requests running under embedded Linux

[Daniel Bowen]

I'm having trouble using QNetworkRequest under embedded Linux.  It's an ARM
9 core - arm_v5t_le.  I've built Qt for Embedded Linux 4.5.1 LGPL flavor for
the platform.  We're using MontaVista 5.

Essentially, QNetworkReply::error() always is giving me an error 301
(QNetworkReply::ProtocolUnknownError) for any URL I try to do a "GET" on.
The same code works fine on Windows and on x86 Linux (Ubuntu 9.04).  On
Windows, I'd gotten error 301 also when I first tried hitting an https:
address, which I soon found that I needed to build OpenSSL and rebuild Qt to
solve.  I have OpenSSL 0.9.8 for both my Linux-x86 and Linux-arm_v5t_le
environments  if that matters (the Linux-arm_v5t_le OpenSSL is a little bit
older - 0.9.8e).

However, with this problem under embedded Linux, I get the
ProtocolUnknownError whether I hit an http: address or a https: address.

I'm including full source for a test app that works on Windows and Linux
x86, but does not work under my embedded Linux environment.  It's a console
app that takes one command line argument - a URL for the resource to
download.  So it can be run with something like
	test http://doc.qtsoftware.com/4.5/how-to-learn-qt.html

 
When I'm at the console on the embedded Linux box, I can ping things just
fine.  I can even run wget, and that downloads things just fine.  But the
test app (as well as the original code I was trying) always gets
ProtocolUnknownError.

What things can I try, or what might I be missing?  Any ideas would be
appreciated!

Thanks!
