compilation of JOBMANAGER: error in BL_JobsManager_QT_moc.cxx

Hi all,

I'm trying to compile the JOBMANAGER module using the SALOME 6.6.0 sources. I created 4 environment variables (KERNEL_BIN_DIR, KERNEL_ROOT_DIR and GUI_ROOT_DIR, GUI_BIN_DIR) which point out on the <SALOME 6.6.0 sources directories>. Apparently I don't have any problems while configuring:

$ ./configure --prefix=<jobmanager_install_dir>

Mandatory products:

  Qt4 (graphic interface)  : yes

  OmniOrb (CORBA) ........ : yes

  Boost           ........ : yes

  SALOME KERNEL .......... : yes

  SALOME GUI ............. : yes

However:

$ make

Gives me the following:

<...>

BL_JobsManager_QT_moc.cxx: In static member function 'static void BL::JobsManager_QT::qt_static_metacall(QObject*, QMetaObject::Call, int, void**)':

BL_JobsManager_QT_moc.cxx:67:62: error: cannot convert from base 'QObject' to derived type 'BL::JobsManager_QT' via virtual base 'QDockWidget'

make[3]: *** [libBL_GenericGui_la-BL_JobsManager_QT_moc.lo] Error 1

Is it normal? What have I done incorrectly?

Thank you,

Dmitry

Hello Dmitry,

It seems that you try to use Qt 4.8, right?

Currently SALOME is not 100% compatible with Qt 4.8. One of the reasons is that virtual inheritance from QObject is prohibited in Qt 4.8.

Also, you have to build KERNEL and GUI modules before JOBMANAGER as JOBMANAGER depends on KERNEL and GUI.

Vadim.

Hello Vadim,

Thank you, indeed the version of Qt is 4.8.3. OK good.

> Also, you have to build KERNEL and GUI modules before JOBMANAGER as JOBMANAGER depends on KERNEL and GUI.

Is it possible to use the pre-built KERNEL and GUI modules which placed in <my_salome_binaries_dir>/Salome-V6_6_0-LGPL-x86_64/modules/? I downloaded them http://salome-platform.org/downloads/current-version#Universal_binaries_for_Linux ? Or I must to rebuild them.

Regards,

Dmitry.

Hello Dmitry,

Normally you should be able to build JOBMANAGER with pre-installed binaries of the products and other SALOME modules. But you should use the same working environment as SALOME itself (e.g. products). Though, I have to say that this way was never tested - universal binaries are mainly aimed to run SALOME, not to build it.

Please try to follow the workflow defined in SALOME documentation: http://docs.salome-platform.org/salome_6_6_0/gui/KERNEL/INSTALL.html .

Regards,
Vadim.
