Re: binary size

["Peter Bui" <peterbui@mybox.cc>]

I faced this problem too, but after some messing around, I found a way to
reduce the executable file size.  Try:

gnatmake -O2 -fno-inline --GNATBIND='gnatbind -shared' sourcefile.adb

Replace sourcefile.adb with your file.  The key here is the
"--GNATBIND='gnatbind -shared' ", which tells the compiler to use the shared
library rather than the static.  I'm not sure if the "-O2" or the
"-fno-inline" really do much, but I haven't really experimented too much
with them.

Anyways, after you compile using the line above you should get an executable
about ~15 kb or something in that neighborhood.  To further reduce the
executable filesize, run:

strip executable

using this I have been able to get a simple Hello World program down to ~6kb
which is a significant reduction.

BTW, I am using Gnat 3.14p on Linux
Good Luck!
