Error while integrating WxWidget2.8 in my 32-bit app in visual studio 2015

Do you have a question about makefiles, a compiler or IDE you are using and need to know how to set it up for wxWidgets or why it doesn't compile but other IDE's do ? Post your questions here.

Error while integrating WxWidget2.8 in my 32-bit app in visual studio 2015

Hi,
I have compiled the wxWidget2.8 statically for both debug and release mode, it successfully compiled, but when i am integrating with my application, it is throwing lot of wxonassert and "wxEmptyString" errors alogn with other wx errors.:
wxwidget2.8 compilation command:
nmake -f makefile.vc CFLAGS="-DJPEG_SUPPORT" CXXFLAGS="-DJPEG_SUPPORT" BUILD=debug UNICODE=1 SHARED=1 DEBUG_INFO=1 USE_OPENGL=1 USE_GUI=1 USE_HTML=1 USE_OBDC=1 USE_THREADS=1 USE_GDIPLUS=1 VENDOR=%2
nmake -f makefile.vc CFLAGS="-DJPEG_SUPPORT" CXXFLAGS="-DJPEG_SUPPORT" BUILD=release UNICODE=1 SHARED=1 DEBUG_INFO=1 USE_OPENGL=1 USE_GUI=1 USE_HTML=1 USE_OBDC=1 USE_THREADS=1 USE_GDIPLUS=1 VENDOR=%2
nmake -f makefile.vc CFLAGS="-DJPEG_SUPPORT" CXXFLAGS="-DJPEG_SUPPORT" BUILD=debug UNICODE=1 SHARED=0 USE_OPENGL=1 USE_GUI=1 USE_HTML=1 USE_OBDC=1 USE_THREADS=1 USE_GDIPLUS=1 VENDOR=%2
nmake -f makefile.vc CFLAGS="-DJPEG_SUPPORT" CXXFLAGS="-DJPEG_SUPPORT" BUILD=release UNICODE=1 SHARED=0 USE_OPENGL=1 USE_GUI=1 USE_HTML=1 USE_OBDC=1 USE_THREADS=1 USE_GDIPLUS=1 VENDOR=%2

i believe there is mismatch in configuration in building wxwidget and my application. Could you please help me out in finding out that difference?

All the "unsigned short const *" in the error messages indicate that the Unicode version of wxWidgets is not found. But the "UNICODE=1" shows that you did build the Unicode libraries.

You either:
- didn't link to the wxWidgets libraries at all
- linked to a wrong (maybe ANSI) version of the libraries
- maybe some preprocessor symbols are wrong/missing. (although that should lead to compiler errors, not linker errors. But who knows...)
Use the source, Luke!

You can try defining "_UNICODE" in addition to "UNICODE" to see if the other or both are needed.
I mean when compiling your application; not when building wxWidgets.
