Compiling qt project with use of ffmpeg on x64 system - qt

I have a qt project that uses some ffmpeg functionality, that i have compiled previously on windows (x86) and ubuntu. However, its x86 binaries do not work correctly on x64 windows machine. I have tried compiling it but have run into a strange problem.
All ffmpeg functions i use are listed as unresolved exgternals; and the most pecicular thing is, their names all ahve a leading underscore attached to them (so, avformat_close_input -> _avformat_close_input etc). To be sure, i have downloaded latest ffmpeg libraries for x64 machines and run them through a dependency walker - no leading underscores anywhere.
How to fix this problem?
Here is my .pro file:

QtCreator can find the files optimizer_test.cpp, optimizer_test.h, readsparameters_test.cpp, and readsparameters_test.h just fine
However, when I invoke qmake from QtCreator, it cannot find the above *.h files.
I've carefully checked that these files are in the specified directories, but qmake keeps throwing the errors that it cannot find these files. qmake finds all the other include files just fine. I can't for the life of me understand why qmake is failing - a real mystery. I've tried removing the build directories as well as cleaning the project.
I've tried uncommenting the DEFINES += QT_DISABLE_DEPRECATED_BEFORE=0x060000
line but it did not help.
Thanks,
Phil
Sorry! I found my stupid mistake!
I had added the "optimizer_test.h" and "optimizer_test.cpp" twice in two different directories. Previously, I had moved the above files from the root sources directory to /carbonics/owncloudsync/programs/C++/cmos_modeling_tests.
Of course, QtCreator tried to find them in the original sources directory to no avail and hence my error messages!
Sorry again to waste your time and thanks!
Phil

when i try to create file .ts with lupdate , the files are generated correctly , but the file .ts not cointeins the qstr strings that are into qml files. ( the file qml are into app.pro ), instead the string that i want to translate into .cpp files are all recognized correctly and put into .ts file.(these are into internal.pro) Where is the problem??
It seems that you are including your .qml files in .qrc resources but not in the project SOURCES itself. lupdate will not pick/parse your .qrc files to list .qml files.
So, you will have to add your .qml files to SOURCES either one-by-one or per directory.
lupdate_only{
SOURCES+=example.qml
SOURCES+=app/FancyControls/*.qml
}
This will duplicate your QML file entries in Qt Creator project pane tree which is not very desirable. So, you can comment out those lines in your .pro file and uncomment it before any lupdate. It's also mandatory to fence those imports in lupdate_only{} conditional statement. Make sure that there is no space between lupdate_only and the curly bracket. Actually, your C/C++ compiler would not expect a qml file to be compiled.

Setting Up Gmock to QT (Windows)

I'm trying unit testing using QT Creator. I tried doing it with linux and it works really fine, but when I start doing it in Windows. I discover the setting up is way different than what I did to linux.
Right now in my Windows QT Creator, I already set up gtest to my project. Everything is working fine until I started to set up googlemock. Can someone tell me how to set up googlemock in QT Creator? (windows)
I added some gmock files in the sources in my .pro file just like what I did to the gtest files. Also, I already add some library like libgmock.a and libgmock_main.a.
Here's the image of the issue results Qt

I experienced the same problem, I suggest you to download other version of gmock. In my case I use gmock 1.7.0. Some older version have some problems/issues. Just follow what the compiler says to you.

Compiling Qt projects on Ubuntu fails every time

History
I've started mining on www.multiport.us and as such I am mining many different coins. Scrypt coins and sha-256.
I'd rather not have all my coins on Cryptsy or Vircuex, so I'm trying to get the Qt GUIs for each of the coins install compiled so I can have wallets on my PC.
Problem
I've been trying for several days now to get this stuff working and I just can't. I've tried with several different coins - Feathercoin, Novacoin, Namecoin, Worldcoin, Freicoin, Zetacoin, etc.
I have tried terminal, and Qt Creator, but I get different errors on each wallet, almost always missing program errors. I get missing bitcoin.cpp, missing QApplication, etc, etc. They just refuse to compile.
Fixes tried
In Qt Creator I have tried adding QT += Widgets, tried a couple of other things too.
In terminal I was originally using 'qmake', then 'make'. But that's been giving me various errors. Missing locale/****, or missing <QApplication>
I have been getting all my source files from the official SourceForge pages, and trying the latest releases and the "master" file list.
System
Ubuntu 13.10
qmake QMake version 3.0
Using Qt version 5.0.2 in /usr/lib/x86_64-linux-gnu
QTCreator version 2.7.1
Following the readme's and instructional files i have also installed the following dependancies
qt4-qmake
libqt4-dev
build-essential
libboost-dev
libboost-system-dev
libboost-filesystem-dev
libboost-program-options-dev
libboost-thread-dev \
libssl-dev
libdb++-dev
libminiupnpc-dev
libgmp3-dev
libmpfr-dev
I really don't know what the problem is. I'm guessing it has something to do with being on 13.10, either that or there is something major I'm just not seeing. But all the source files are the same, they are built so all you need to do is qmake and make, to compile on your own system and then run. But I'm just having no luck at all.
QT Creator is version 2.7.1 from the repository.

As I have said the instructions that all of the wallets I'm trying to compile come with say the exact same thing.
Bitcoin-Qt: Qt4 GUI for Bitcoin
===============================
Build instructions
===================
Debian
-------
First, make sure that the required packages for Qt4 development of your
distribution are installed, these are
::
for Debian and Ubuntu <= 11.10 :
::
apt-get install qt4-qmake libqt4-dev build-essential libboost-dev libboost-system-dev \
libboost-filesystem-dev libboost-program-options-dev libboost-thread-dev \
libssl-dev libdb4.8++-dev
for Ubuntu >= 12.04 (please read the 'Berkely DB version warning' below):
::
apt-get install qt4-qmake libqt4-dev build-essential libboost-dev libboost-system-dev \
libboost-filesystem-dev libboost-program-options-dev libboost-thread-dev \
libssl-dev libdb++-dev libminiupnpc-dev
then execute the following:
::
qmake
make
Alternatively, install `Qt Creator`_ and open the `bitcoin-qt.pro` file.
An executable named `bitcoin-qt` will be built.
.. _`Qt Creator`: http://qt-project.org/downloads/
Mac OS X
--------
- Download and install the `Qt Mac OS X SDK`_. It is recommended to also install Apple's Xcode with UNIX tools.
- Download and install either `MacPorts`_ or `HomeBrew`_.
- Execute the following commands in a terminal to get the dependencies using MacPorts:
::
sudo port selfupdate
sudo port install boost db48 miniupnpc
- Execute the following commands in a terminal to get the dependencies using HomeBrew:
::
brew update
brew install boost miniupnpc openssl berkeley-db4
- If using HomeBrew, edit `bitcoin-qt.pro` to account for library location differences. There's a diff in `contrib/homebrew/bitcoin-qt-pro.patch` that shows what you need to change, or you can just patch by doing
patch -p1 < contrib/homebrew/bitcoin.qt.pro.patch
- Open the bitcoin-qt.pro file in Qt Creator and build as normal (cmd-B)
.. _`Qt Mac OS X SDK`: http://qt-project.org/downloads/
.. _`MacPorts`: http://www.macports.org/install.php
.. _`HomeBrew`: http://mxcl.github.io/homebrew/
Build configuration options
============================
UPnP port forwarding
---------------------
To use UPnP for port forwarding behind a NAT router (recommended, as more connections overall allow for a faster and more stable bitcoin experience), pass the following argument to qmake:
::
qmake "USE_UPNP=1"
(in **Qt Creator**, you can find the setting for additional qmake arguments under "Projects" -> "Build Settings" -> "Build Steps", then click "Details" next to **qmake**)
This requires miniupnpc for UPnP port mapping. It can be downloaded from
http://miniupnp.tuxfamily.org/files/. UPnP support is not compiled in by default.
Set USE_UPNP to a different value to control this:
+------------+--------------------------------------------------------------------------+
| USE_UPNP=- | no UPnP support, miniupnpc not required; |
+------------+--------------------------------------------------------------------------+
| USE_UPNP=0 | (the default) built with UPnP, support turned off by default at runtime; |
+------------+--------------------------------------------------------------------------+
| USE_UPNP=1 | build with UPnP support turned on by default at runtime. |
+------------+--------------------------------------------------------------------------+
Notification support for recent (k)ubuntu versions
---------------------------------------------------
To see desktop notifications on (k)ubuntu versions starting from 10.04, enable usage of the
FreeDesktop notification interface through DBUS using the following qmake option:
::
qmake "USE_DBUS=1"
Generation of QR codes
-----------------------
libqrencode may be used to generate QRCode images for payment requests.
It can be downloaded from http://fukuchi.org/works/qrencode/index.html.en, or installed via your package manager. Pass the USE_QRCODE
flag to qmake to control this:
+--------------+--------------------------------------------------------------------------+
| USE_QRCODE=0 | (the default) No QRCode support - libarcode not required |
+--------------+--------------------------------------------------------------------------+
| USE_QRCODE=1 | QRCode support enabled |
+--------------+--------------------------------------------------------------------------+
Berkely DB version warning
==========================
A warning for people using the *static binary* version of Bitcoin on a Linux/UNIX-ish system (tl;dr: **Berkely DB databases are not forward compatible**).
The static binary version of Bitcoin is linked against libdb4.8 (see also `this Debian issue`_).
Now the nasty thing is that databases from 5.X are not compatible with 4.X.
If the globally installed development package of Berkely DB installed on your system is 5.X, any source you
build yourself will be linked against that. The first time you run with a 5.X version the database will be upgraded,
and 4.X cannot open the new format. This means that you cannot go back to the old statically linked version without
significant hassle!
.. _`this Debian issue`: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=621425
Ubuntu 11.10 warning
====================
Ubuntu 11.10 has a package called 'qt-at-spi' installed by default. At the time of writing, having that package
installed causes bitcoin-qt to crash intermittently. The issue has been reported as `launchpad bug 857790`_, but
isn't yet fixed.
Until the bug is fixed, you can remove the qt-at-spi package to work around the problem, though this will presumably
disable screen reader functionality for Qt apps:
::
sudo apt-get remove qt-at-spi
.. _`launchpad bug 857790`: https://bugs.launchpad.net/ubuntu/+source/qt-at-spi/+bug/857790
But when I try and compile with QT Creator or through terminal I get:
home/kun7/CoinMining/zetacoin-0.8.3/src/qt/bitcoin.cpp:5: error: QApplication: No such file or directory
I have found that lots of people are adding 'QT += widgets' to their .ro files and it fixes it, but when I do that I get:
/home/kun7/CoinMining/zetacoin-0.8.3/src/qt/bitcoin.cpp:122: error: 'setCodecForTr' is not a member of 'QTextCodec'
/home/kun7/CoinMining/zetacoin-0.8.3/src/qt/bitcoin.cpp:123: error: 'setCodecForCStrings' is not a member of 'QTextCodec'
/home/kun7/CoinMining/zetacoin-0.8.3/src/qt/bitcoin.cpp:123: error: 'codecForTr' is not a member of 'QTextCodec'
What am I missing?
The issue has been fixed!!!
I was a moron.
I was trying to run
qmake
make
But my system has qmake version 5 installed and i installed verion 4 as per the dependencies. So instead, to get the program to compile correctly, i need to force the use of version 4...
qmake-qt4
make
Voiala!!!!!

collect2.exe:-1: erreur : error: ld returned 1 exit status
It looks like you're using incompatible libraries.
This tells me that you're using the MinGW compiler
report->setReportFile("E:\apprendreQt\build-gestionstock6-Desktop_Qt_5_1_0_MinGW_32bit-Debug\reports\abdeu.xml");
but in your .pro file, you're including a static linking library from a different compiler (most likely MS Visual Studio)
LIBS = "E:\apprendreQt\gestionstock6\includes\lib\NCReport2.lib"
libraries for MinGW should have a .a extension, not a .lib one.
Not only that, you're using the LIBS variable incorrectly. For a MinGW compiler, you should specify the library path(with -L) and the library itself(with -l) separately.
You could do this on separate lines:
LIBS += "-L/path/to/libraries"
LIBS += "-lmylibrary.a"
or in a single line:
LIBS += "-L/path/to/libraries -lmylibrary.a"
