So, I have a small project with a very simple code. All it really does is create a wxFrame the following way:
wxFrame(NULL, -1, title, wxPoint(-1, -1), wxSize(380, 220))
There is no compiling problem to any of my code whatsoever. The problem occures when I do this line:
IMPLEMENT_APP(App);
App is:
class App: public wxApp
So, when I do that and I hit compile, I have the following errors:
1>LINK : warning LNK4098: defaultlib 'MSVCRT' conflicts with use of other libs; use /NODEFAULTLIB:library
1>CApp.obj : warning LNK4248: unresolved typeref token (01000019) for 'wxVideoMode'; image may not run

I would appreciate any help!
Regards.
where is defined g_isPainting ?
Did you add the right library to the linker for wxAppConsole ?

Greeting
I have application made with QT 4.8.5 and Visual Studio 2008. For some reason i need to update my QT to 5.5.1 and my Visual Studio to 2010. I downloaded qt-everywhere-opensource-src-5.5.1 and build-ed for Visual Studio 2010.
configure -debug-and-release -opensource -platform win32-msvc2010 -icu -openssl -nomake examples -prefix C:\QT-Compile
nmake
nmake install
When i build my solution, I get following errors :

Actually there is a lot more, I'm just mentioning some of them.
I know unresolved external symbol error is about linker can not finding libraries but as i checked in Linker->General->Additional Library Directories, All lib directory are imported.
What i'm missing here !!!
Thanks in advance!!!
I found the problem.
Before QT5 i was using following lines in my CMakeLists.txt.
FIND_PACKAGE(Qt5 REQUIRED)
...
TARGET_LINK_LIBRARIES(project-name
${QT_LIBRARIES}
...)
With QT5 i need to change them to following form.
find_package(Qt5 REQUIRED COMPONENTS Core Gui Network Sql WebKit Widgets Multimedia)
...
TARGET_LINK_LIBRARIES(project-name
Qt5::Widgets Qt5::Core Qt5::Gui Qt5::Network Qt5::Sql Qt5::WebKit Qt5::Multimedia
...)
these errors are coming when compiling in release and X64..

added linker settings and also vc++ directory settings still the above errors are coming. please do needful, to generate pgAdmin3.exe in release folder.
The above error is because of linking an invalid libxslt.lib file, it got fixed by changing that linked libxslt.lib to correct 64bit file.
Right now I'm just trying to get 'www.google.com' to load in a webview when a button is pressed. After I added the webview in the designer the linker starts going crazy. I'm using QT Creater 2.6.1 with QT5 on Windows 7. I added the QT += 'webkit stuff' to the .pro file. I've tried cleaning and rebuilding, still get linker errors.
for some odd reason adding "#include <QWebView>" in any file produces a file not found error: "C:\Users\Scott\Desktop\eCookBook\eCookBook2\cookbook.cpp:3: error: C1083: Cannot open include file: 'QWebView': No such file or directory"

When executing step 'Make'
First try "Run qmake" (from the "Build" menu in Creator) to regenerate the make files and then re-build. Basically you need "Run qmake" after every modification in the .pro file.
Press Ctrl+5 in Creator.
Uncheck "Shadow build".
Change your .pro file line to:
QT += core gui network webkit webkitwidgets
Rebuild the project
The same bug fixed. Try to add path to qwebview.h in the include like:
(change "QtWebKitWidgets" to yours)
#include <QtWebKitWidgets/QWebView.h>
instead of just #include <QWebView.h>
Try to add it to all files that use QWebView.
I coded a BitPacker object that takes in various types of data and packs them to a buffer using the fewest number of bits required to store their values. I created a separate solution to make this into a DLL for reuse-ability. I was successfully able to link to it from another solution and use it. However I ran into the problem of these two function prototypes in the DLL being ambiguous when trying to pass in a long long for "data" instead of an int:
static __declspec(dllexport) unsigned long long UnpackBits(char *srcBuffer, long long data, unsigned int &offsetBits, const unsigned int numBits);
static __declspec(dllexport) unsigned int UnpackBits(char *srcBuffer, int data, unsigned int &offsetBits, const unsigned int numBits);
static __declspec(dllexport) float UnpackBits(char *srcBuffer, float data, unsigned int &offsetBits);
There is no problem when I'm simply passing an int. Since I can't think of a way to remove the ambiguity to support both data types I decided to modify the DLL source by commenting out the "long long" versions from the header and source files and recompiling them (both for Debug and Release). However after doing that I'm receiving linker errors for pretty much every call to that DLL now. I don't know why since I also changed the instances of where I was using a long long data member to int to make sure there was no reference to the old long long version that I commented out.

I tried cleaning the calling project, manually deleting all the object files and doing a Rebuild All but the errors remain. I'm thinking it is somehow still using an old version of the DLL header file and/or lib but don't know how or why. Is there something I need to do in my calling Solution for it to "re recognize" the new DLL?
PS - And while I'm asking anyone have any advice on the ambiguity problem? I'd like to be able to support both 32 and 64 bit data types but not sure how. I thought about simply getting rid of the int version and only having the long long version but then I worry about the possibility of data becoming truncated when catching the return type back into an int.
I have a C++ project that uses IBPP to access a firebird database. I simply do it by including the file "all_in_one.cpp" in my project, and all went well with both VS6 (yes, I still have some of those) and VS2008.
Now I am considering using VS2010. It is compiling ok but does not link. I know VS2010 comes with a new implementation of the STL, and the linking problem obviously is around the STL.
I have tried creating a new project with VS2010, just adding the all_in_one.cpp file. It is a simple project that does not contain anything else, and it still fails to link with the same missing symbols. I can't figure out what's missing, incorrect. I have tried linking to the same libraries as in VS2008 (including the path). Nothing is working so far.

It seems your library/DLL is exporting some templated/STL stuff.
STL is not binary compatible among different compiler versions.
You need to use same compiler/linker/bitness to compile and link the DLL/EXE if STL/template is involved.
Remove the all_in_one.cpp from build and use the other files from core to build the library.
Concerning linker errors 10 and 11 from the error list above, I have the following solution
(probably it fixes all errors).
Open the property pages of your project by right clicking your project inside the Solution Explorer and selecting "Properties".
Inside the "Property Pages"-window:
--> open "Configuration Properties" from left menu
--> select "VC++ Directories" on the left
--> go to "Library Directories" on the right
--> the corresponding string should contain a sub-string like
"C:\Program Files (x86)\Microsoft Visual Studio 9.0\VC\lib"
--> replace "9.0" by "10.0"
to make the changes working "re"build your solution (perhaps clean your solution first).
