Windows VS2010 based QTCreator and 3rd party libraries SOLVED
-
I have Qt Creator 3.0.1 installed with the Qt 5.2.1 (MVSC 2010, 32 bit) libraries. I am new to Qt and it's been quite a few years since my C++ training so I am struggling in general. It's difficult to judge if I have a problem with my Qt project configuration or with the sample code I am trying to run. Right now I think it has to do with configuring the project correctly in Qt.
The sample project is called HelloWorldQt.pro.
@
QT += widgets
TEMPLATE = app
TARGET = HelloWorldQt
INCLUDEPATH += "C:/Program Files/MetaMAP/MetaMAP Engine 2 SDK/include"
QMAKE_LIBDIR += "C:/Program Files/MetaMAP/MetaMAP Engine 2 SDK/libs"HEADERS +=
./helloworldqt.h
"C:/Program Files/MetaMAP/MetaMAP Engine 2 SDK/include/MetaMAP/Engine/Controls/QtMapControl.hpp"SOURCES +=
./main.cpp
./helloworldqt.cppFORMS +=
./helloworldqt.ui
@When I try to build the project I get the following error:
_dependent 'C:\Program' does not exist_
What do I need to do to make this work?
-
If you use e.g. message($$HEADERS), you'll see that there are no " anymore, so QMake thinks C:/Programm is a single argument as they are divided by spaces. ;)
Using " instead of " for all three paths should solve the problem!Regards

I have made progress. I changed the paths to use environment variables. They contain spaces but I can now build the project but unsuccessfully. I am getting new error messages.
The UI has a customwidget. It's in the file helloworldqt.ui file. Under the QMainWindow the centralWidget implements MetaMAP::Engine::QtMapControl. When I attempt to build the project I get three duplicate errors in ui_helloworldqt.h.
Cannot open include file: 'MetaMAP/Engine/Controls/QtMapControl.hpp': No such file or directory
I have double checked that the header file is there. If I open the UI file in a text editor the custom widget has the following:
@
<customwidget>
<class>MetaMAP::Engine::QtMapControl</class>
<extends>QWidget</extends>
<header>MetaMAP/Engine/Controls/QtMapControl.hpp</header>
<container>1</container>
</customwidget>
@Now what am I doing wrong?
-
Hi,
@
QMAKE_LIBDIR += "C:/Program Files/MetaMAP/MetaMAP Engine 2 SDK/libs"
@Should rather be:
@
LIBS += -L$$quote("C:/Program Files/MetaMAP/MetaMAP Engine 2 SDK/libs")
@If this still doesn't work, it means that the spaces are wreaking havoc. Then the best thing to do is use the 8.3 naming.
Something like@
LIBS += -LC:/PROGRA~1/MetaMAP/METAMA~1

Thanks for your input. Ok, so I might have a problem with the LIBDIR. However, it's the include path I have a problem with. Right? I ask this because you changed from QMAKE_LIBDIR to LIBS. Also you added the -L. I'll look that up in the manuals. That's great if that is necessary. But how will that resolve the problem with the includes?
I changed to the 8.3 names with no change in the results.
-
Why are you putting a header from that library in INCLUDES ? It's not part of your sources
-
I have gotten these problems resolved. The include you questioned was required to be able to use the 3rd party API. When I removed it from the .pro file I got hundreds of compile errors.
I had to use the 8.3 short names for the project to compile. I understand. The world of desktop development is focused on the Linux environment and those doing Windows only development have to accommodate. I just had to get it figured out.
