Hi all,
I am new to U++ and I think it is a great TOOL!!

So I am trying my first programs (examples) e for several times when linking the folowing erro appear:

___main: duplicate
-> used: libmingw32.a:gccmain.o:1
-> discarded: libgcc.a:__main.o:1
1 undefined symbol(s):

Why compiling MyUppApp downloaded from the forum it also have this error! see output:

----- CtrlLib ( GUI GCC DEBUG DEBUG_FULL BLITZ WIN32 ) (1 / 9)
----- CtrlCore ( GUI GCC DEBUG DEBUG_FULL BLITZ WIN32 ) (2 / 9)
----- RichText ( GUI GCC DEBUG DEBUG_FULL BLITZ WIN32 ) (3 / 9)
----- Draw ( GUI GCC DEBUG DEBUG_FULL BLITZ WIN32 ) (4 / 9)
----- Core ( GUI GCC DEBUG DEBUG_FULL BLITZ WIN32 ) (5 / 9)
----- plugin/bmp ( GUI GCC DEBUG DEBUG_FULL BLITZ WIN32 ) (6 / 9)
----- plugin\z ( GUI GCC DEBUG DEBUG_FULL BLITZ WIN32 ) (7 / 9)
----- plugin\png ( GUI GCC DEBUG DEBUG_FULL BLITZ WIN32 ) (8 / 9)
----- MyUppApp ( GUI MAIN GCC DEBUG DEBUG_FULL BLITZ WIN32 ) (9 / 9)
