Merkaartor

My approach is to stuff like that:

.pro

INCLUDEPATH +=src/QFatFs
DEPENDPATH += src/QFatFs
include(src/QFatFs/QFatFs.pri)

.pri

SOURCES += \
    QFatFs.cpp \
    QFat.cpp \
    QFatFile.cpp

HEADERS += \
    QFatFs.h \
    QFat.h \
    QFatFile.h

This way, I can have kind of "subprojects" while having no issue with #include's

Thanks Chris for your light speed answer !

In the particular case of Merkaartor, this would mean :

merkaartor
  \_ src
     \_ common/common.pri
     \_ src.pro

myproject
   \_ main.cpp
   \_ mywindow.h
   \_ mywindow.cpp
   \_ myproject.pro

With :

myproject.pro

MERKAARTOR_DIR = $$PWD/../merkaartor
MERKAARTOR_SRC_DIR = $$MERKAARTOR_DIR/src

INCLUDEPATH += $$MERKAARTOR_SRC_DIR $$MERKAARTOR_DIR/include $$MERKAARTOR_DIR/interfaces
DEPENDPATH += $$MERKAARTOR_SRC_DIR $$MERKAARTOR_DIR/include $$MERKAARTOR_DIR/interfaces

INCLUDEPATH += ../merkaartor/src/common
DEPENDPATH += ../merkaartor/src/common
include(../merkaartor/src/common/common.pri)

INCLUDEPATH += ../merkaartor/src/Utils
DEPENDPATH += ../merkaartor/src/Utils
include(../merkaartor/src/common/Utils.pri)

SOURCES += main.cpp\
           mywindow.cpp\
           MainWindow.cpp

HEADERS  += mywindow.h\
            MainWindow.h

FORMS    += mywindow.ui

It could compile but could not link because of something that looks strange to me :

../merkaartor/src/MainWindow.cpp: In member function ‘void MainWindow::incomingLocalConnection()’:
../merkaartor/src/MainWindow.cpp:495:50: error: no matching function for call to ‘MainWindow::connect(QTcpSocket*&, const char*, QTcpSocket*&, const char*)’
/usr/include/qt4/QtCore/qobject.h:198:17: note: candidates are: static bool QObject::connect(const QObject*, const char*, const QObject*, const char*, Qt::ConnectionType)
/usr/include/qt4/QtCore/qobject.h:313:13: note:                 bool QObject::connect(const QObject*, const char*, const char*, Qt::ConnectionType) const

I don't want to bother you, and would prefer asking much more interesting questions, but did I understand well what you suggested ?

Thank you,
Mathieu

I don't think this error has something to do with your project structure.

It would look like "MainWindow" is not a QObject anymore? Is it on purpose?

Got it !
An #include <QTcpSocket> was missing in Merkaartor MainWindow.cpp, thus considering QTcpSocket as an empty struct as defined in MainWindow.h

(my goal is to use Merkaartor source tree as it is, and avoid hacks as much as possible)

I go on slowly, thank you !

Stuck again on QtToolBarDialog... strange, it's probably the most standalone component !

moc_qttoolbardialog.cpp: In member function ‘virtual int QtToolBarDialog::qt_metacall(QMetaObject::Call, int, void**)’:
moc_qttoolbardialog.cpp:143:25: error: invalid use of incomplete type ‘struct QtToolBarDialogPrivate’
../merkaartor/3rdparty/qttoolbardialog-2.2_1-opensource/src/qttoolbardialog.h:104:7: error: forward declaration of ‘struct QtToolBarDialogPrivate’
moc_qttoolbardialog.cpp:144:25: error: invalid use of incomplete type ‘struct QtToolBarDialogPrivate’

even though I added :

include($$MERKAARTOR_DIR/3rdparty/qttoolbardialog-2.2_1-opensource/src/qttoolbardialog.pri)

When you have incomprehensible "moc" errors, Clean-Qmake-Build is the way to go...

Indeed, it was !

(took me time to figure out that some old moc_* files were still in merkaartor source folder...)

In case someone needs a similar setup, please find my example in attachment.
