Big executable program size

Big executable program size

[fracttcarf]

I downloaded gnat-gpl-2005-pentium-mingw32msv-bin.exe for win98
and compiled hello.adb
This hello.exe size is 1520kb. why?
My english is poor. ㅜㅜ

You can narrow the search to by language, too:

The simple answer is that your program has statically linked in a lot of 
stuff it doesn't use. You could look at gnatelim if you're interested in 
how much of that is really needed.

A longer answer points out that much of the excess is relatively fixed, 
and is not a significant proportion of a "real" program, where it's also 
more likely to be needed.

Here a few hello world programs from the Wikibook Ada Programming:

1,1M ./Windows_NT-i686-Debug/hello_world_2.exe
1,1M ./Windows_NT-i686-Debug/hello_world_3.exe
1,1M ./Windows_NT-i686-Debug/hello_world_1.exe
16K ./Linux-x86_64-Release/hello_world_1
16K ./Linux-x86_64-Release/hello_world_2
16K ./Linux-x86_64-Release/hello_world_3
36K ./Linux-i686-Debug/hello_world_2
36K ./Linux-i686-Debug/hello_world_3
36K ./Linux-i686-Debug/hello_world_1
12K ./Linux-i686-Release/hello_world_1
12K ./Linux-i686-Release/hello_world_2
12K ./Linux-i686-Release/hello_world_3
40K ./Linux-x86_64-Debug/hello_world_1
40K ./Linux-x86_64-Debug/hello_world_2
40K ./Linux-x86_64-Debug/hello_world_3
20K ./Windows_NT-i686-Release/hello_world_2.exe
20K ./Windows_NT-i686-Release/hello_world_3.exe
20K ./Windows_NT-i686-Release/hello_world_1.exe

You see there are significant variation here - the smallest is 12K the
largest 1.1M. Perhaps you might want to have a look how we set up the
project files.

 Also, different Ada compilers generate substantially different exe sizes,
presumably depending on how their designers view the cost of
disk/RAM/bandwidth vs the cost of trimming out the fat.
