Static Linking 2.5.1 in Qt

[Skeith]

Hi All,

I'll try and be succinct. I have an engine project which is made up of two QProjects. The engine 'runtime' builds as a static library which is the editor then links against in addition to using SFML itself (drawing into a QWidget for the viewport). I've recently been trying to link SFML statically in an attempt to simplify the process of actually getting a functioning binary.

Here is the SFML-specifics of my 'runtime' QProject file:

# SFML
DEFINES += SFML_STATIC

INCLUDEPATH += "$$PWD/../ThirdParty/SFML/include"
DEPENDPATH += "$$PWD/../ThirdParty/SFML/include"

LIBS += -L"$$PWD/../ThirdParty/SFML/lib"
CONFIG(release, debug|release):
{
    #SFML-System Libs
    LIBS += -lsfml-system-s         #SFML Static Module
    LIBS += -lwinmm                 #Dependency

    #SFML-Window Libs
    LIBS += -lsfml-window-s         #SFML Static Module
    LIBS += -lsfml-system-s         #
    LIBS += -lopengl32              #Dependency
    LIBS += -lgdi32                 #Dependency
    LIBS += -lwinmm                 #Dependency

    #Audio Related Libs
    LIBS += -lsfml-audio-s          #SFML Static Module
    LIBS += -lsfml-system-s         #
    LIBS += -lopenal32              #Dependency
    LIBS += -lFLAC                  #Dependency
    LIBS += -lvorbisenc             #Dependency
    LIBS += -lvorbisfile            #Dependency
    LIBS += -lvorbis                #Dependency
    LIBS += -logg                   #Dependency

    #SFML-Graphics Libs
    LIBS += -lsfml-graphics-s       #SFML Static Module
    LIBS += -lsfml-window-s         #
    LIBS += -lsfml-system-s         #
    LIBS += -lfreetype              #Dependency
}

The editor QProject file also has the same SFML-specifics in it so I won't duplicate it needlessly.

Anyway, the errors come when attempting to build the editor (the runtime builds fine, without issue - though I appreciate the error could be in the runtime and is simply manifesting when I try to build the editor):

I've been looking into/attempting this over the last few evenings and my frustration has become such that I must reach out and ask for some help.

Any assistance you could provide would be really appreciated.

Thank you.

A quick google search for GetDC/DestroyCursor/etc reveals that these functions are part of User32.dll
Not sure why User32 isn't automatically linked for you, but I guess you'll have to add it.

As a general tip, if you see some symbol that failed to link, you can just google it and usually quite quickly find the library that is missing from the linking settings.

Thank you Exploit, suppose I naively assumed an SFML issue, I'll try your suggestion and report back. Thanks for the respone.

Back, so I updated my QProject files with the following:

LIBS += -luser32
LIBS += -lGdi32
LIBS += -ladvapi32

This resolved my original problem and allowed me to build my application.

However, even though I could now build the application successfully, running it simply resulted in a generic error message. So, in an attempt to investigate this I switched back to debug mode, updated my QProject files with the "-s-d" versions of the SFML libraries only to be met with 100+ instances of this:

sfml-audio-s-d.lib(Music.cpp.obj) : error LNK2038: mismatch detected for '_ITERATOR_DEBUG_LEVEL': value '2' doesn't match value '0' in main.obj
sfml-audio-s-d.lib(Music.cpp.obj) : error LNK2038: mismatch detected for 'RuntimeLibrary': value 'MDd_DynamicDebug' doesn't match value 'MD_DynamicRelease' in main.obj

I understand there's some Debug/Release mismatch somewhere but for the f**king life of me I can't work out where...

[Skeith]

Nevermind, I stupidly had a line saying "CONFIG += release" in one of my QProject files (probably from a past attempt to resolve some other issue).
