Running a video with QMediaPlayer : undefined symbol - qt

I’m trying to run a simple application that plays a video with Qt Multimedia, but I got the following error:
`(TestMultimedia:17734): GStreamer-WARNING **: Failed to load plugin '/usr/lib64/gstreamer-0.10/libgstfcdec.so': /usr/lib64/gstreamer-0.10/libgstfcdec.so: undefined symbol: __gst_debug_min`
It looks like I have a wrong version of libgstfcdec.so. Am i right and how to solve this issue?
Can any one help me, please?
Thanks in advance.

compilation issue : libvlc exception t is missing

I'm trying to mix Qt and libVLC, I've downloaded libs, tried some tutorials, but I always stop on the same error and I can't find any solution in Google...
Here's the compilation output
error: unknown type name 'libvlc_exception_t'; did you mean 'libvlc_event_t'?
I'm running MacOS 10.8.4
EDIT : the libvlc_exception_t is not even documented on LibVLC Doc
That's why :
doc/ChangeLog-2010: The libvlc_exceptions have been removed from libvlc.

Qt + Zlib => error LNK2005: _deflate_copyright already defined in QtCored.lib(deflate.obj) zlibstat.lib

When I link my application I receive the following message:
error LNK2005: _deflate_copyright already defined in QtCored.lib(deflate.obj) zlibstat.lib
I'm not sure of the problem, but... I use QT and ZLib. Both are "static libraries". The problem is that the QTCore.lib contains ZLib too!
Project Qt: contains its own version on ZLib.
Project GenericLib: use an external ZLib.lib (cannot be linked to Qt).
Project main: use Qt + Generic lib.
As I say, I'm not sure that it is the problem. But, anyway, if someone has an idea to help me?
Thanks for your help.

Problem statically linking to Botan on Windows using MSVC

I am trying to statically link a Qt library I am building to Botan using MSVC on Windows and am receiving the following error.
..\..\3rdparty\temp\botan-msvc\build\include\botan/secmem.h(129) : error C2589: '(' : illegal token on right side of '::'
..\..\3rdparty\temp\botan-msvc\build\include\botan/secmem.h(128) : while compiling class template member function 'void Botan::MemoryRegion<T>::copy(const T [],size_t)'
with
[
T=Botan::byte
]
..\..\3rdparty\temp\botan-msvc\build\include\botan/buf_comp.h(41) : see reference to class template instantiation 'Botan::MemoryRegion<T>' being compiled
with
[
T=Botan::byte
]
..\..\3rdparty\temp\botan-msvc\build\include\botan/secmem.h(129) : error C2059: syntax error : '::'
This does not occur with MinGW. It also occurs when I comment out all Botan-related code. What does this mean and how can I solve it - also why does it not occur with MinGW?
I was able to figure out the issue with help from Jack Lloyd's comment. Apparently something that's included through one path or another #defined "min". I just undefined it and my library compiles and links perfectly. Thanks Jack!

Fatal error: Call to undefined function cypher_previousposts() in wordpress

I have wordpress site. I have installed modern-blue-green-120070612-2 theme.Then i got an error message on the right hand side "Fatal error: Call to undefined function cypher_previousposts() in mydomain\wp-content\themes\modern-blue-green-120070612-2\sidebar.php on line 59.
Does any one know this? Please help me ....
Thaks in advance
cypher_previousposts seems to be coming from a plug-in named "Previous Posts" (see e.g. here). The author seems to be running the site cypherhackz.net. I'd recommend you search for this plugin in the official WP plugin repository and install it from there.
