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

[Daniel Bowen]

OK, I have it working now!  It was how I was building Qt for Embedded Linux
for the arm_v5t_le.  I was excluding a little too much it seems.

 

I have a fairly aggressive ./configure going on for the Linux-arm_v5t_le
environment to reduce the size (as well as editing common/g++.conf to use
-Os).  I'm not sure of the exact combination, but there were a few
"-no-feature-X" guys I had, that when I removed made it work.  For the
-no-feature things, I'd made a shell script to parse the qfeatures.txt file
to give me a complete list I could feed to ./configure.  I went through each
one, and took out the -no-feature based on a rough idea of what it might
effect.  But, it looks like I needed to leave out a couple more (so that the
feature was left in).

 

Here's the ones I had but took out to make t work:

 

                -no-feature-TEXTSTREAM

                -no-feature-TEXTCODEC

-no-feature-CODECS 

                -no-feature-IMAGEFORMATPLUGIN

                -no-feature-PROPERTIES

 

Not sure which one(s) was the magic one, but it was one or more of those.

 

And for the record, here's my new (for the moment at least) ./configure
(gives me a 2.0 MB libQtCore.so.4.5.1, 858 KB libQtNetwork.so.4.5.1, 209 KB
libQtXml.so.4.5.1) :

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

 

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!

-Daniel
