Im trying to install qt-pods on windows.
I downloaded the qt-pods package from github to my pc.
then i went into the folder and tried to run qmake && make.
the qmake succeed with no errors (i did it also alone for checking) but the 'make' threw me the following errors:
...a lot of errors like this...

I followed the steps on how to install azerothcore. I remembered I could add Modules, so I went in the website of azerothcore and downloaded a few modules. Before I downloaded them I checked and saw it says that it's building on master core, but for some reason I have the following error:
/usr/bin/ld: ../../../modules/libmodules.a(ModulesLoader.cpp.o): in function `AddModulesScripts()':

and I am not capable of fixing it. Can anyone please help?
Remove _master from all module subdirectories.
You can avoid this error by using git clone or cloning the modules in general with a git interface, instead of downloading a .zip file.
I tried to find the same case as mine, but I couldn't. Most of them here are about undefined reference error during compiling their own code, but in my case this error occurred while installing OpenCV.
I referred to this page :
http://milq.github.io/install-opencv-ubuntu-debian/
I use armv7l and debian-scratch 9.3.
I tried to install OpenCV 3.4.0
I have this error :

I found out it's from a linking library error, but as I'm a beginner of Linux, it couldn't help me.
I hope this question is clear.
I just upgraded my system from Ubuntu 15.10 to Ubuntu 16.04 LTS. Now, for some reason my C++ project won't compile anymore. CLion keeps saying it's missing 'libx264.so.146 as you can see in the compile log:

Most people seem to give 'reinstalling x264' as a solution. However, reinstalling x264 with the following commands leads to the same error while compiling x264 itself.
git clone git://git.videolan.org/x264
cd x264
./configure --enable-static
make
/usr/bin/ld: warning: libx264.so.146, needed by /usr/local/lib/libavcodec.so, not found (try using -rpath or -rpath-link)

Does anyone have an idea how I could get around this?
Okay, after a day of trying to remove and recompile the liavcodec-dev library, without result, I decided to format the drive and reinstall Ubuntu from scratch.
Everything is working fine now.
I'm stuck trying to get some openCV code working on my raspberry pi. I'm almost certain the problem is caused by the linker not knowing where the openCV library files are but I'm unfamiliar with both Linux and Netbeans so I'm in a bit of a pickle!
So, in short, my set-up is: attempting to build my code to my raspberryPi via remote C++ build host (G++). I am writing my code in Netbeans.
The builds worked fine up until the point I wrote two new classes using the "opencv2/core/core.hpp"
Now, when I attempt to build, I get the following error/s:

Any ideas?
I'm sure I just need to point the linker to the appropriate libs but I've no idea how to specify that relative path when using a build host.

I have the code in this gist
https://gist.github.com/hassanshaikley/0721dd9f791a94629bfc
this error is strange because I include the necessary components. : (
you need to use the following options in the compiler:
-L to include your library search path
-l to add the particular libraries that need to be included
