I've tried to compile it on Linux and there is an error:
TopWinX11.cpp
/home/ivica/upp/uppsrc/CtrlCore/TopWinX11.cpp: In member function `void
TopWindow::SyncCaption()':
/home/ivica/upp/uppsrc/CtrlCore/TopWinX11.cpp:135: error: `XA__NET_WM_ICON'
undeclared (first use this function)
/home/ivica/upp/uppsrc/CtrlCore/TopWinX11.cpp:135: error: (Each undeclared
identifier is reported only once for each function it appears in.)
Sorry... as there is another bug in TheIDE, looks like we will have to release RC2 soon
