i have used Qt Eclipse and i have succeed the compilation of FET (original source), but when i delete forms from project i have problems with reference:

how can i resolve this problem!

I use Windows, MinGW GCC and Qt 4.4.1.

I have create new project c++ in eclipse, i have add engine source to project and i have add all include and librerie of QT to project.

when i build the project i have this result:

i have error in compilation:
engine\activity.cpp:115: error: 'class QStringList' has no member named 'find'

i don't know how can i resolve this problem!

Please can you look at the sample,when i try to activate the last activity, i will have in result generation the "assertion window"!

When i start the solver i have this assertion window.

Please,i want to know what this assertion mean!

this is the file of rules.cpp with modification.

this is the entire code of fet.cpp, i used solve function as entry point to run up the engine.

when i ignore a "assertion failed" i get this message in the console:

Code Select Expand

Duplicate room - 1
Cannot precompute - data is wrong - aborting

i tried to initialize the structure of engine with an init() function in fet.cpp that i invoke it after each execution of engine:

Code Select Expand

extern "C" void init(){
                 INPUT_FILENAME_XML="";

                 gt.rules.kill();
                 gt.rules.init();

                 
                 students_schedule_ready=false;
                 teachers_schedule_ready=false;
                 rooms_schedule_ready=false;
}

but without success!

please, what can i need to initialize the entire structure of engine!

I try to integrate  FET with a java application as DLL, i have succeed to load library and turn up the engine but when i try to reuse engine for another instance i get message box alert.
please how can i initialize structure of engine for reuse it!

i have add stop function as below:

extern "C" void stop (){

     if(!simulation_running){
                 /*QMessageBox::critical(this, TimetableGenerateForm::tr("FET information"),
                  TimetableGenerateForm::tr("Simulation stopped but the simulation is not running."
                  " This should not happen. Maybe you aborted simulation previously. Please report possible bug to author"));*/

                 return;
           }

           simulation_running=false;

           mutex.lock();
           gen.abortOptimization=true;
           mutex.unlock();

           
}


when i execute solver and i try to stop it i have this message:

ASSERT failure in QCoreApplication::sendEvent: "Cannot send events to objects owned by a different thread.


please, have you response about this!

i have integrated FET with java application as DLL.

i have succeed to run Generate::generate function, but sometime i want to stop it.

please how can i control the execution of this function!

i am newbie in how to make a dll, i have make FEt as library in output template but when i have tried to invoke some function (throw java class) i have got problem:

Exception in thread "main" java.lang.UnsatisfiedLinkError: Error looking up function 'test'

the specifique function is not founded (test function is just a function that return the value 1, i have add it in fet.cpp).

please, have it a special thinks that i need to do to resolve the problem!

Commande line version it's what I need, but about XML have you the shemat for input (*.fet) and output (subgroups_timetable.xml, teachers_timetable.xml) files.

I want use FET as an API, I want use FileDataInput as param method and have FileDataOutput as result. Is it possible to do?

i think i have checked a solution for my problem:

i don't use break or "activity split + preferred time constraint", i think i need to use some think like a template of preferred time for each activity.

if i have activity with 2h00 i will add constrain of preferred time that check a plan of 2h00:

allowed(2h)|not allowed(10mn)|allowed(2h)|not allowed(10mn)...

if i have activity with 1h30 i will add constrain of preferred time that check a plan of 1h30:

allowed(1h30)|not allowed(10mn)|allowed(1h30)not allowed(10mn)...

now about activity of 3h that must be consecutive, i will add constraint of preferred time (is like that i have plan of 3h00):

allowed(3h)|not allowed(20mn)|allowed(3h)...

with this solution i think i can resolve problem of consecutive activity but i have many gap in timetable that i cannot optimize with min gap between activity constraint.

please how can i resolve this!
