Windows includepath and libs

[luca72]

hello i'm under windows if in the .pro file i add this
@
LIBS += -lClasse_scarico_rev_01
INCLUDEPATH += C:\librerie_luca\Classe_scarico_rev_01
@

i get c:/qt/2010.05/mingw/bin/../lib/gcc/mingw32/4.4.0/../../../../mingw32/bin/ld.exe: cannot find -lClasse_scarico_rev_01

if i write this
@
LIBS += C:\librerie_luca\Classe_scarico_rev_01
LIBS += -lClasse_scarico_rev_01
@
i get c:/qt/2010.05/mingw/bin/../lib/gcc/mingw32/4.4.0/../../../../mingw32/bin/ld.exe: C:\librerie_luca\Classe_scarico_rev_01: No such file: Permission denied

What is wrong

Thanks Luca

Edit: one thing that's wrong is your use of @ tags for the code ;-) ; Andre

[andre]

The includepath is aimed at where header files are found. Not where library files are found. That is documented in the qmake Variable Reference documentation.

[luca72]

The .h file of the lib that i need to use are in

C:\librerie_luca\Classe_scarico_rev_01

@
LIBS += -LC:\librerie_luca\Classe_scarico_rev_01

[andre]

Better not to use backslashes though. They will trigger a qmake warning :-)

[luca72]

@QT += core gui network webkit
TARGET = Excalibur_rev_01
TEMPLATE = app
SOURCES += main.cpp\widget.cpp
HEADERS += widget.h
FORMS += widget.ui
#LIBS += C:\librerie_luca\Classe_scarico_rev_01
LIBS += -LC:\librerie_luca\Classe_scarico_rev_01
INCLUDEPATH += C:\librerie_luca\Classe_scarico_rev_01@

I get:

Edit: fixed use of @ tags: only one tag needed per code block; Andre

Did you try to re-run qmake and make clean and make to rebuild you project. Seems like the QNetwork lib is not in the link list.

[luca72]

yes but i get the same error

Luca

[goetz]

did you remove this line?

@LIBS += -lClasse_scarico_rev_01@

if yes, your lib is not linked to your program!

-L adds a library search path (like -I does for includes)
-l adds a particular library to your exe

(I misread the error message, actually there is not QtNetwork missing, but some of your own classes).

[luca72]

I never remove this but i get the same error:
From the program i have access to all the member of the class but i can't compile, this is the -pro file:

@QT += core gui network webkit

TARGET = Excalibur_rev_01
TEMPLATE = app

SOURCES += main.cpp
widget.cpp

HEADERS += widget.h

FORMS += widget.ui

LIBS += -LC:\librerie_luca\Classe_scarico_rev_01 -lClasse_scarico_rev_01

INCLUDEPATH += C:\librerie_luca\Classe_scarico_rev_01
@

and the error that i get is this:

[giesbert]

Just one idea, can you please post a dir listing of this folder:
C:\librerie_luca\Classe_scarico_rev_01

[luca72]

Hello
I have delete the lib an the program folder, remake all exact the same and now the program work.
Many thanks for you help and time

Luca
