[Solved] QTCreator Linker Error

[Live-Dimension]

I've been trying to get SFML and QT to work together over the last few days, but I just can't seem to figure out whats wrong. Pretty much there is a whole bunch of errors on "undefined reference".

I've tried the code on the tutorial site and it's still not working. Yes the paths are relative, this QT Project is apart of a set of apps.

Here is the project file for QT.

Code: [Select]


INCLUDEPATH += ../src
TEMPLATE = app
TARGET = SHUMPEditor

DESTDIR = ..\..\editor-debug

win32:LIBS += "../lib/debug/sfml-audio-s-d.lib" \
"../lib/debug/sfml-graphics-s-d.lib" \
"../lib/debug/sfml-window-s-d.lib" \
"../lib/debug/sfml-system-s-d.lib" \
"../lib/debug/sfml-network-s-d.lib"

#FORMS +=
HEADERS += QSFMLCanvas.h
SOURCES += QSFMLCanvas.cpp \
    main.cpp


The compile log. I took out alot of repeated "undefined reference to bla bla bla"

Error while building project SHUMPEditor

I'd appreciate any help! I've been trying this for 3-4 nights now with no luck.

You're using the Visual C++ libraries instead of the MinGW ones.

[Live-Dimension]

Ahh, blast! I should of picked that up!

Thanks!

edit: It works. I kinda forgot about the different kinds of libs, having always been a Visual C++ user! :oops:

Thank you for posting this thread, I didn't know what my error was for a long time
