In my experience, --enable-single-host is much more important than --enable-gcc-opts for speed.

Yes, with --enable-single-host option Gambit runs about 1.5 to 2 times faster. But on my x86_64 machine compilation with some not-so-good versions of GCC (4.3.x) take about 10 Gigabytes of virtual memory in peak and near 30 minutes. If target architecture is 32bit with small amount of registers (x86, for instance), then --enable-single-host is strongly recommended option.

PS: For MIPS32 arch on Au1250 system compilation of Gambit took about 6 hours with --enable-single-host :)

The time stamps on your files seems to be inconsistent. Please start from a freshly unpacked gambc-v4_5_3.tgz . If that doesn't work, you can probably do "touch */*.c" and then "make".

Hi Everyone,

Thanks for your help. Unfortunately I am getting errors during the build process. I tried:

./configure --prefix=/home/nikhil/Programs/Scheme --enable-gcc-opts --enable-single-host

Everything seems to be fine except a warning message that some optimization will not work. But when I invoked make, the attached error message popped up. Please help!

Thanks,

Nikhil

These things are defined in lib/_repl.scm . Look for this definition:

(define prompt "> ")

and also the procedure definition ##repl-debug-main .

Are you sure you are not doing your users a disservice by hiding the fact that they are using the Gambit interpreter? Also, the ">" prompt is fairly universal and users may find it annoying (for instance most tutorials use the ">" to indicate the prompt).

Hi!

I am integrating Scheme with my other tool-chain and I need to make some changes to it to make it consistent.

1. I observed that Gambit starts with some colouring (bold while on blue

background) and the text we type is also bold in colour. I want to disable all test colouring so that everything appears simple regular test.

2. I want to prompt to change from ">" to " * ".

3. Insead of the Gambit v4_5.3 message, I would prefer it just says

"Scheme".

I downloaded the gambc-v4_5_3-devel.tgz file and I was trying to go through the source code but I could not figure out where these formatting were define. Can someone tell me how I can make the above changes or at the very least, where in source code can I do the modifications?

Thanks in advance,

Nikhil

Hi!

Last versions of Gambit are stable.

follow next instructions (for Linux):

get source code here: http://www.iro.umontreal.ca/~gambit/download/gambit/v4.5/source/gambc-v4_5_3...

unpack it: tar -xzf gambc-v4_5_3.tgz

configure it:

if you have fast computer with lots of memory (i need more than 6 Gig on my 64 bit desktop to compile gambit with this options):

./configure --enable-gcc-opts --enable-single-host

otherwise:

./configure --enable-gcc-opts

make all sources:

make

and install:

sudo make install

and you'll get two main programs installed: gsi and gsc. gsi - interpreter and gsc is compiler scheme-to-c and c-to-obj via gcc.

Use gsi to learn basic features of scheme.

I may recommend next books to read:

1. SICP

http://mitpress.mit.edu/sicp/full-text/book/book.html 2. Concepts, Techniques, and Models of Computer Programming www.ulb.ac.be/di/rwuyts/INFO020_2003/vanRoyHaridi2003-book.pdf 3 Concrete Abstractions http://gustavus.edu/+max/concrete-abstractions.html 4.

Hi,

I am new to Gambit as well as new to Scheme programming. I would like to download and use a Stable version of scheme. Also, I want to compile from source rather than use the binary distribution.

Can someone tell me which file I need to download? I see bunch of files in the site. Which version is the stable version? And further whats the difference between gambc-v#_#_#-devel.tgz & gambc-v#_#_#.tgz and which one should I download?

Thanks,

Nikhil
