How can built a small as 5 Kbytes "Hello World" program ?
I built a "Hello World" program as follows,
type h.scm (display "Hello ") type w.scm (display "World") gsc -link h w gsc -obj h.c w.c w_.c gcc -o w.exe h.o w.o w_.o C:/Gambit-C_64bit/v4.7.3/lib/libgambc.a -lws2_32 w.exe Hello World
This way, the size of the "w.exe" is 4.61MB. In Gambit-C manual documents 3. The Gambit Scheme compiler 3.4 Link files ... A "Hello World" program built this way can be as small as 5 Kbytes. ... Could you please teach me how to built program as small as 5 Kbytes one. Thanks in advance.
You need to configure Gambit using --enable-shared, i.e. ./configure --enable-single-host --enable-shared make This will build a DLL for the Gambit runtime library, so that the .exe doesn’t contain the runtime library. Marc

Thank you very much for replying. I downloaded the "gambc-v4_7_3.gz", then $ ./configure --enable-single-host --enable-shared $ make I could get a "libgambc.dll" now.
type h.scm (display "Hello ") type w.scm (display "World") gsc -link h w gsc -obj h.c w.c w_.c gcc -o w.exe h.o w.o w_.o libgambc.dll -lws2_32 w.exe Hello World
This time the size of the "w.exe" is 136KB. It's very small. Thank you very much again for your help. -----Original Message----- From: Marc Feeley Sent: Monday, January 19, 2015 1:51 PM To: Ryuho Yokoyama Cc: gambit-list@iro.umontreal.ca Subject: Re: [gambit-list] How can built a small as 5 Kbytes "Hello World" program ?

How can this possibly be considered "small" for such a trivial task, let along *very* small? That's three times the entire RAM of the first machine I ran a HelloWorld program on! I really wonder what is filling up all those K! -- hendrik

That's much smaller than the 136KB mentioned in the post I was replying to. " This time the size of the "w.exe" is 136KB. It's very small. Good job. Now I really wonder what was going on in the 136KB, or whether 136KB was a typo. -- hendrik

It is probably the ws2_32 library that is statically linked. But frankly on modern machines the difference in space between 5 MB (static link) and 5 KB (shared libs) doesn’t really matter very much. I almost always favour a static link because it avoids the headache of setting up the shared lib path, version compatibility, etc. Moreover, it is probably marginally faster to load the executable code from a single file.
