I found bug which causes FSME crash. It is fixed and new tarball have been uploaded. Use and enjoy!

I've followed instructions from main web page from sf.net and tried to compile, but got this error with "std::auto_ptr" :

g++ -c -pipe -fPIC -O2 -Wall -W -D_REENTRANT -DLONG64 -DQT_NO_DEBUG -DQT_QT3SUPPORT_LIB -DQT3_SUPPORT -DQT_XML_LIB -DQT_GUI_LIB -DQT_CORE_LIB -DQT_SHARED -I/usr/share/qt4/mkspecs/linux-g++ -I. -I/usr/include/qt4/QtCore -I/usr/include/qt4/QtGui -I/usr/include/qt4/QtXml -I/usr/include/qt4/Qt3Support -I/usr/include/qt4 -I. -I../kernel -I../diagram -I.. -I.moc -I.ui -o .obj/main.o main.cpp

what is wrong with that auto_ptr?

Please get the last snapshot from hg repository.

Or include <memory> header. Also you will need to include <stdlib.h> in syntax.cpp.

I am a newbie to FSME and mercurial, so maybe I made something wrong. But downloading rel. 1.06 from sourceforge got me to the same error.
Getting from mercurial, I get the same compile error:
MainWindow.h:49:5: error: ‘auto_ptr’ in namespace ‘std’ does not name a type
make[1]: *** [.obj/main.o] Errore 1

I use OpenSuse 12.1 64bit
Please any advice?
Thank you

Next portion is here (there are similar :: things), I dont know how to recover from this:

In file included from netwm.h:37:0,
from netwm.cpp:31:
netwm_def.h:284:4: error: expected ‘}’ before ‘::’ token
netwm_def.h:284:24: error: invalid use of ‘::’
netwm_def.h:285:13: error: ISO C++ forbids initialization of member ‘Toolbar’
netwm_def.h:285:13: error: making ‘Toolbar’ static
netwm_def.h:285:13: error: ISO C++ forbids in-class initialization of non-const static member ‘Toolbar’
netwm_def.h:285:13: error: invalid conversion from ‘int’ to ‘NET::WindowType’
...

I think that would be enough to remove netwm.cpp from ui.pro. Qt4 should handle semi-transparent app icons properly.

I have fixed that on mercurial repository.

How I could've done with this app when I was at Uni doing computer science! However, that was 14 years ago - sigh.

This program is not intended to be only a demo. Many things can be modeled with FSM, not only parsers/regular expressions!

FSM in FSME is more UML State Diagram rather automata from Dragon Book. This means you can create Finite State Machine, which acts as object reacting some Events and producing some Actions.

For example, there are 2 FSM in FSME itself: Manipulator handler and View manager.
