The first thing to do when learning a new programming language is to write an obligatory 'hello world' program.

% wget https://code.call-cc.org/releases/5.2.0/chicken-5.2.0.tar.gz
% tar xvfz chicken-5.2.0.tar.gz
% cd chicken-5.2.0
% make PLATFORM=linux PREFIX=/usr/local/chicken
% make PLATFORM=linux PREFIX=/usr/local/chicken install
% make PLATFORM=linux PREFIX=/usr/local/chicken check

The first thing to do when learning a new programming language is to write an obligatory 'hello world' program. The first step is to download the source code and build it. Quick start instructions are available here

More detailed instructions provided for linux below

% sudo apt-get install build-essential
% git clone git@github.com:gambit/gambit.git
% cd gambit
% ./configure --prefix=/usr/local/gambit --enable-single-host --enable-targets=js --enable-default-compile-options="(compactness 9)" \
             --enable-multiple-versions --enable-openssl --enable-default-runtime-options=f8,-8,t8 --enable-poll
% make #compile
% make modules #compile modules
% make check
% make doc
% sudo make install #installation directory is configured with --prefix=/usr/local/gambit
% sudo ldconfig #this makes sure the newly installed library in /usr/local/lib are reloaded
% sudo make uninstall #use only if you need to uninstall binaries in /usr/local

#ignore the warning below about --eanble-single-host
#See https://github.com/gambit/gambit/issues/502#issuecomment-600610891

*** The option "--enable-single-host" was not specified to the         *** 
*** configure script.  The Gambit system will compile correctly but    *** 
*** typically the executables will run considerably slower than when   *** 
*** "--enable-single-host" is specified.  On the other hand the build  *** 
*** with "--enable-single-host" is typically slower and requires lots  *** 
*** of RAM memory (>= 1 GB).  If you are willing to wait for the       *** 
*** longer build, try the configure option "--enable-single-host".     *** 
***                                                                    ***

% gsi -:d$ #starts gambit scheme interpreter with remote REPL running on port 44555
Gambit v4.9.3-1404-gf738de00

> (println "hello world")
hello world

the -:d$ option tells gsi to start a remote socket REPL on port 44555. You can evaluate at the console REPL or 'telnet localhost 44555' to remote REPL and evaluate expressions.
