I have project written in C++ that use Qt Framework and QScintilla2. I cannot build Release because of linker errors. I'm using Visual Studio 2013.

I have built icu 64.2 (debug and release for both x86 and x64). My build passes all the tests, so I know icu is not the issue.
I have also built a 64-bit version of boost 1.70.0 using the following b2 build command:
b2 address-model=64 -sICU_PATH=C:\icu-release-64-2\icu4c threading=multi --build-type=complete --toolset=msvc-14.1 -j 6
b2 is detecting my icu build and is showing:
- has_icu builds : yes
When I try to build my project with this boost/regex/icu code:
bool is_valid_password(const icu::UnicodeString& password, const icu::UnicodeString& requirements)
{
return boost::u32regex_match(password, boost::make_u32regex(requirements));
}
I get the following error:

I should also note that I built icu and boost with the same compiler and MSVC toolset. Any ideas why boost wouldn't be linking to icu?

I ended up building libstudxml-1.0.1 (http://www.codesynthesis.com/projects/libstudxml/ ) and linking xlnt.test with that library resolves the undefined symbol issue.
Also note that on my system xlnt does not link successfully with libstudxml-1.0.1 and it has to be linked with xlnt-master\third-party\libstudxml...\libstudxml.lib
I'm trying to create a project using the QGIS class "QApplication" but it seems to fail due to an error I can´t understand.
I'm using this build version of QGIS made for QT5.7, VS2015, W10 x64 and my main.cpp just containts the following lines:
#define CORE_EXPORT __declspec(dllexport)
#include "QGisTest.h"
#include <QtWidgets/QApplication>
#include <qgsapplication.h>
int main(int argc, char *argv[])
{
QApplication a(argc, argv);
QGisTest w;
w.show();
return a.exec();
}
And when I try to build it, these errors show up:

I also added to the project this "moc_qgsapplication.cpp" and wrote the line:
#define CORE_EXPORT __declspec(dllexport)
to avoid other compilation problems and linked to the project the QGIS and QT 5.7 libs.
Any idea how to fix it?
EDIT:
I have changed the two lines of main.cpp as suggested and now contains the following code:
#define CORE_EXPORT __declspec(dllimport)
#include "QGisTest.h"
#include <QApplication>
#include <qgsapplication.h>
int main(int argc, char *argv[])
{
QApplication a(argc, argv);
QGisTest w;
w.show();
return a.exec();
}

I am trying to build a C++ application which connects to Perforce Server but build fails because it cannot find the p4api libraries.
I am new to C++, Visual Studio and p4api so I probably did something wrong.
I am using Windows 8 and Visual Studio 2013 Professional.
Details:
I downloaded p4api.zip from ftp://ftp.perforce.com/perforce/r15.2/bin.mingw64x64/
Notice that the libraries found in p4api.zip are of type .a where as in the Chapter 2 of user guide says that for Windows it should be .lib
Visual Studio Configuration:
From Visual Studio, Project properties -> Configuration Properties:
Linker -> General -> Additional Libraries Directories => I specified the directory containing the p4api .a files eg C:\Users\myuser\Documents\Visual Studio 2013\Projects\ProjectName\ProjectName\lib\p4api
Linker -> Input -> Additional Dependencies => I specified the name of each .a file in the order described on user guide. I also added extra libs as described in this blog eg libclient.a;librpc.a;libsupp.a;libp4sslstub.a;wsock32.lib;libcmt.lib;oldnames.lib;kernel32.lib;ws2_32.lib;advapi32.lib
Linker -> Command Line -> Additional Options => As in user guide eg /DOS_NT /MT /DCASE_INSENSITIVE
C/C++ -> General -> Additional Include Directories => I specified the location of perforce header files eg C:\Users\myuser\Documents\Visual Studio 2013\Projects\ ProjectName\ProjectName\include\p4

========== Build: 0 succeeded, 1 failed, 0 up-to-date, 0 skipped ==========
Additional concerns:
1) Did I download the correct p4api? I cannot find a folder specifically for Windows. The only folder which looks more relevant to Windows is bin.mingw
2) Why the library files are of type .a not .lib?
3) Did I set the dependencies correctly on Visual Studio? If yes, why build fails?
Please let me know if you need more details.
Thanks in advance.
I'm getting a bunch of LNK2001 and LNK2019 errors with Qt 5.4 and Crypto++. Tried both static and dynamic linking. Libs are in the project folder and .pro file has something like:
win32: LIBS += -L$$PWD/ -lcryptlib
INCLUDEPATH += $$PWD/include
DEPENDPATH += $$PWD/include
win32:!win32-g++: PRE_TARGETDEPS += $$PWD/cryptlib.lib
else:win32-g++: PRE_TARGETDEPS += $$PWD/libcryptlib.a
As soon as I reference something from cryptopp header files I get 15+ linker errors. Also, lib was built with the same MSVC2013 compiler I'm using for Qt.
Any ideas?
EDIT: Yeah, sorry for not including the errors.

I'm using downloaded Qt, and in about section of Qt Creator it says it's compiled with MSVC 2010 32bit.
