[gambit-list] How can built a small as 5 Kbytes "Hello World" program ?

[Ryuho Yokoyama]

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.

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窶冲 contain the runtime library.
