[solved] can't compile moolticute

[khippy]

See, I have a Mooltipass Box and want to give Moolticute a try.

Raouls github page says, his software needs QT5 which I assume, do have.

So I gave it a shot:

Code: Select all

# mkdir build
# cd build
# qmake ../Moolticute.pro
# make
make -f Makefile.daemon 
make[1]: Entering directory '/usr/local/src/git/moolticute/build'
g++ -c -pipe -O2 -Wall -W -D_REENTRANT -DQT_NO_DEBUG -DQT_NETWORK_LIB -DQT_CORE_LIB -DQT_SHARED -I/usr/share/qt4/mkspecs/linux-g++ -I../../moolticute -I/usr/include/qt4/QtCore -I/usr/include/qt4/QtNetwork -I/usr/include/qt4 -I. -I../../moolticute -I. -o main_daemon.o ../src/main_daemon.cpp
In file included from ../src/main_daemon.cpp:20:0:
../src/AppDaemon.h:22:24: fatal error: QApplication: No such file or directory
 #include <QApplication>
                        ^
compilation terminated.
Makefile.daemon:313: recipe for target 'main_daemon.o' failed
make[1]: *** [main_daemon.o] Error 1
make[1]: Leaving directory '/usr/local/src/git/moolticute/build'
Makefile:38: recipe for target 'sub-daemon-pro-make_default' failed

# locate QApplication
/usr/include/qt4/QtGui/QApplication
/usr/include/qt5/QtGui/QApplicationStateChangeEvent
/usr/include/qt5/QtWidgets/QApplication

You see, qmake is obviously using QT4.

Good. I googled and then I used

Code: Select all

# qmake -qt=5 ../Moolticute.pro
# make
( test -e Makefile.daemon || /usr/lib64/qt5/bin/qmake /usr/local/src/git/moolticute/daemon.pro -o Makefile.daemon ) && make -f Makefile.daemon 
make[1]: Entering directory '/usr/local/src/git/moolticute/build'

In file included from ../src/main_daemon.cpp:20:0:
../src/AppDaemon.h:22:24: fatal error: QApplication: No such file or directory

                        ^
compilation terminated.

make[1]: Leaving directory '/usr/local/src/git/moolticute/build'
Makefile:41: recipe for target 'sub-daemon-pro-make_first' failed
make: *** [sub-daemon-pro-make_first] Error 2

This time it uses qmake version 5 but includes files from QT4.

Now google didn't help anymore and I need assistance.

What can I do?

Hi khippy

Code: Select all

fatal error: QApplication: No such file or directory

there is something missing... and that is the inclusion of /usr/include/qt4/QtGui/QApplication header file (or of its QT5 counterpart)

In the various "-I" options passed to the compiler, no one includes /usr/include/qt4/QtGui/ nor /usr/include/qt5/QtWidgets/:

Code: Select all

g++ -c -pipe -O2 -Wall -W -D_REENTRANT -DQT_NO_DEBUG -DQT_NETWORK_LIB -DQT_CORE_LIB -DQT_SHARED -I/usr/share/qt4/mkspecs/linux-g++ -I../../moolticute -I/usr/include/qt4/QtCore -I/usr/include/qt4/QtNetwork -I/usr/include/qt4 -I. -I../../moolticute -I. -o main_daemon.o ../src/main_daemon.cpp

If the developer says it requires for qt5, I suggest you to go for that
Anyway, are you trying this on a Gentoo system?

Regards

[khippy]

I do. I am at a gentoo forum, right?

I have no clue how to prepare a QT5 environment at my system which has QT4 as default and QT5 aswell.
I have also opened an issue at Raoulh's repository but he has no clue about Gentoo.

I do. I am at a gentoo forum, right?

Sadly, this is not so obvious for many people...

Anyway, a QT5 application that includes all those "/usr/include/qt4/whatever" headers looks strange to me...

Just to confirm that this is the problem, you can run that

Code: Select all

g++ -c -pipe -O2 -Wall -W -D_REENTRANT -DQT_NO_DEBUG -DQT_NETWORK_LIB -DQT_CORE_LIB -DQT_SHARED -I/usr/share/qt4/mkspecs/linux-g++ -I../../moolticute -I/usr/include/qt4/QtCore -I/usr/include/qt4/QtNetwork -I/usr/include/qt4 -I. -I../../moolticute -I. -o main_daemon.o ../src/main_daemon.cpp

by hand, from the /usr/local/src/git/moolticute/build directory, adding the -I/usr/include/qt4/QtGui/ or the -I/usr/include/qt5/QtWidgets/ option to the command
If you are able to compile the expected "main_daemon.o", it is a step ahead

Regards

[khippy]

Code: Select all

build # g++ -c -pipe -O2 -Wall -W -D_REENTRANT -DQT_NO_DEBUG -DQT_NETWORK_LIB -DQT_CORE_LIB -DQT_SHARED -I/usr/share/qt4/mkspecs/linux-g++ -I../../moolticute -I/usr/include/qt4/QtCore -I/usr/include/qt4/QtNetwork -I/usr/include/qt4 -I. -I../../moolticute -I. -o main_daemon.o ../src/main_daemon.cpp
In file included from ../src/main_daemon.cpp:20:0:
../src/AppDaemon.h:22:24: fatal error: QApplication: No such file or directory
 #include <QApplication>
                        ^
compilation terminated.

The QT4 includes seem not to be the problem (in between I am pretty shure they are needed), but QApplication still can't be found.

Hi khippy

...adding the -I/usr/include/qt4/QtGui/ or the -I/usr/include/qt5/QtWidgets/ option to the command...

I meant to execute something like this, e.g. for QT4:
g++ -c -pipe -O2 -Wall -W -D_REENTRANT -DQT_NO_DEBUG -DQT_NETWORK_LIB -DQT_CORE_LIB -DQT_SHARED -I/usr/share/qt4/mkspecs/linux-g++ -I../../moolticute -I/usr/include/qt4/QtCore -I/usr/include/qt4/QtNetwork -I/usr/include/qt4 -I. -I../../moolticute -I/usr/include/qt4/QtGui -I. -o main_daemon.o ../src/main_daemon.cpp

Regards

[khippy]

Ok, I've tried with qt4/QtGui

Code: Select all

g++ -c -pipe -O2 -Wall -W -D_REENTRANT -DQT_NO_DEBUG -DQT_NETWORK_LIB -DQT_CORE_LIB -DQT_SHARED -I/usr/share/qt4/mkspecs/linux-g++ -I../../moolticute -I/usr/include/qt4/QtCore -I/usr/include/qt4/QtNetwork -I/usr/include/qt4 -I. -I../../moolticute -I/usr/include/qt4/QtGui -I. -o main_daemon.o ../src/main_daemon.cpp 
In file included from ../src/MPManager.h:29:0,
                 from ../src/AppDaemon.h:27,
                 from ../src/main_daemon.cpp:20:
../src/MPDevice_linux.h:22:20: fatal error: libusb.h: No such file or directory
 #include <libusb.h>
                    ^
compilation terminated.

... and with qt5/QtWidgets

Code: Select all

build # g++ -c -pipe -O2 -Wall -W -D_REENTRANT -DQT_NO_DEBUG -DQT_NETWORK_LIB -DQT_CORE_LIB -DQT_SHARED -I/usr/share/qt4/mkspecs/linux-g++ -I../../moolticute -I/usr/include/qt4/QtCore -I/usr/include/qt4/QtNetwork -I/usr/include/qt4 -I. -I../../moolticute -I/usr/include/qt5/QtWidgets -I. -o main_daemon.o ../src/main_daemon.cpp 
In file included from /usr/include/qt5/QtWidgets/QApplication:1:0,
                 from ../src/AppDaemon.h:22,
                 from ../src/main_daemon.cpp:20:
/usr/include/qt5/QtWidgets/qapplication.h:45:35: fatal error: QtGui/qguiapplication.h: No such file or directory
 #include <QtGui/qguiapplication.h>
                                   ^
compilation terminated.

Both have new not found errors.

*arrgh* I don't see getting one step further in this case. I am going to check this at a debian machine today.

Eureka
there is a piece missing in the puzzle: dev-qt/qtwebsockets

I was trying it by myself,and I've faced exactly the errors you have met so far.... but:
- qmake inclusion of "qt4" stuff was suspicious, since project states that QT5 is required instead
- "qmake -v" stated I'was working with QT4:

Code: Select all

kikko@seireitei /tmp/moolticute-master/build $ qmake -v
QMake version 2.01a
Using Qt version 4.8.7 in /usr/lib64/qt4

- I've tried removing everything the build/ directory, starting from scratch. I've used the command qmake -qt=5 ../Moolticute.pro directly in the empty dir
- now make stated "Project ERROR: Unknown module(s) in QT: websockets"
- looking for websocket in Portage, revealed the package stated above; emerged it, make is successful

[khippy]

Correct!

Emerging dev-qt/qtwebsockets solved the issue.

moolticute compiles fine, now.

Thank you for your help!
