Hi, I am trying to compile amSynth-1.0-rc2. When compiling files under the src/GUI directory, these unexpected error messages happen: make[3]: Entering directory `/home/ismaeval/Projects/local/amSynth-1.0-rc2/src/GUI' source='GUI.cc' object='GUI.o' libtool=no \ depfile='.deps/GUI.Po' tmpdepfile='.deps/GUI.TPo' \ depmode=gcc /bin/sh ../../config/depcomp \ g++ -DHAVE_CONFIG_H -I. -I. -I../.. `gtkmm-config --cflags` `gtk-config --cflags` -Wall -O3 -ffast-math -fno-exceptions -fomit-frame-pointer -Dwith_oss -Dwith_alsa -c -o GUI.o `test -f 'GUI.cc' || echo './'`GUI.cc In file included from GUI.h:24, from GUI.cc:4: ParameterView.h:34: warning: `class ParameterView' has virtual functions but non-virtual destructor In file included from GUI.h:29, from GUI.cc:4: ControllerMapDialog.h: In method `gint ControllerMapDialog::delete_event_impl(GdkEventAny *)': ControllerMapDialog.h:25: warning: control reaches end of non-void function `ControllerMapDialog::delete_event_impl(GdkEventAny *)' In file included from GUI.cc:4: GUI.h: In method `int GUI::delete_events(GdkEventAny *, Gtk::Window *)': GUI.h:63: warning: control reaches end of non-void function `GUI::delete_events(GdkEventAny *, Gtk::Window *)' GUI.cc: In method `GUI::GUI(Config &, MidiController &, VoiceAllocationUnit &, int *, GenericOutput &, const char *)': GUI.cc:152: implicit declaration of function `int WEXITSTATUS(...)'
