Hello
I'm using:
binutils-2.9.1
gcc-2.8.1
gnat-3.12p
newlib-1.8.2
rtems-4.0.0
I'm trying to build ada_hello_world and I'm getting a "multiple definition of `main'" error:
/root/rtems/install/ada/bin/i386-rtems-gnatmake -v -O -gnata -gnatE -gnato hello -g \

What I'm doing wrong?
Thanks

PS: I'm using the following makefile:
