how to fix " Missing argument to '-L' " error ?
-
Could you show your .pro file?
What exactly do you mean by "suddenly"? Did a restart, update occur between the working and non-working state?#------------------------------------------------- # # Project created by Ahtisham 2016-08-16T13:18:59 # #------------------------------------------------- QT += core gui greaterThan(QT_MAJOR_VERSION, 4): QT += widgets TARGET = testMyProject TEMPLATE = app SOURCES += main.cpp\ eyecare.cpp \ others.cpp HEADERS += eyecare.h \ others.h FORMS += eyecare.ui RESOURCES += \ images.qrc win32:CONFIG(release,debug|release): LIBS += -L&&PWD/Dll/ -ldxva2 win32:CONFIG(release,debug|release): LIBS += -L$$PWD/Library/ -ldxva2 else:win32:CONFIG(debug, debug|release): LIBS += -L$$PWD/Library/ -ldxva2 else:unix: LIBS += -L$$PWD/Library/ -ldxva2 INCLUDEPATH += $$PWD/Library DEPENDPATH += $$PWD/Library win32:CONFIG(release, debug|release): LIBS += -L$$PWD/Library/ -luser32 else:win32:CONFIG(debug, debug|release): LIBS += -L$$PWD/Library/ -luser32 else:unix: LIBS += -L$$PWD/Library/ -luser32 INCLUDEPATH += $$PWD/Library DEPENDPATH += $$PWD/Library DISTFILES +=no neither restart nor update occurred but i don't know what caused this problem it was working fine.

In here shall be probably a '$' sign
win32:CONFIG(release,debug|release): LIBS += -L&&PWD/Dll/ -ldxva2change to
win32:CONFIG(release,debug|release): LIBS += -L$$PWD/Dll/ -ldxva2Vote the answer(s) that helped you to solve your issue(s)

Good to see it's funny to you ;-)
Can you edit the link to you image or just copy the text here? We cannot see the image in your previous post.
You can use an image provider to show it to us by following this topic
There is still a problem with the uploading of image in the Qt forum. The admins are working on it though.Edit : did you check the hint from @koahnig ?

why do you have those 2 lines?
win32:CONFIG(release,debug|release): LIBS += -L$$PWD/Dll/ -ldxva2 win32:CONFIG(release,debug|release): LIBS += -L$$PWD/Library/ -ldxva2Is one of them not enough?
The Dll path seems redundant since you don't use it further onQt Certified Specialist

win32:CONFIG(release,debug|release): LIBS += -L$$PWD/Dll/ -ldxva2but still getting those 3 errors
I use that Dll file for getting some windows functions that i need in my project.
functions like :
GetDesktopWindow();
MonitorFromWIndow();
GetCurrentBrightness();
etc -

etcThe problem ist that this is only working for release. Therefore, you need to be sure that you are in release mode.
Also sometimes it is good to rerun qmake and possibly rebuild your libraries. -

3 windows dll files
dxva2.dll, dxva264.dll and user32.dll
no libs with those file names?
The dlls are used during run time, but while linking you need to have the libs created together with the dlls there.Vote the answer(s) that helped you to solve your issue(s)

now i got the libs but still getting that error :(
What is the actual error message with your current configuration?
Probably it would be good also to post the current .pro file.Vote the answer(s) that helped you to solve your issue(s)
