@rileylevy95_gitlab
Thank you
Ideally, would i run that script instead of ./configure?

@junkerjoe
That is really useful. Thanks @feeley

Hi @feeley , how do you debug the gambit compiler? Do you run it completely in the interpreter? Do you start with the binary and then load in the interpreter what you'd like to debug?
luca regini
@lucaregini
By "debugging" I really intended single-stepping in the source of the compiler. What's the most convenient way to do that?
Bradley Lucier
@gambiteer
Try gsc/igsc.scm.

In a clean git checkout of master, if I try to git checkout v4.9.3, I get an error about "local changes" to some files. My workaround was to use git worktree add v4.9.3 v4.9.3.
is it OK if the makefile tries to build some modules that fail with errors on some targets?
François-René Rideau
@fare
looks like gambit has been trying to compile _digest for riscv-64 at 100% cpu for 40 minutes.
Jaime Fournier
@ober
local changes happens I found when you are using a modified tree. git clean -xfd always fixed it for me. as per @belmarca advice

How to specify additional include directories in gsi?

@drewc I saw that section, which is the right option? I see only The ‘=DIRECTORY’ option overrides the setting of the central installation directory.
and
The ‘~~DIR=DIRECTORY’ option overrides the setting of the DIR installation directory.
These options are not what I am looking for
I need to add paths, not to ovveride the installation directory
Drew Crampsie
@drewc
If you (or the code) is using "~~" as a prefix to the libs, is that not by its very nature an installed gambit library?
(eval '(begin
        (##namespace ("c#"))
        (##include "~~/lib/header.scm")))

@gambiteer

This seems to work

This is in the Gambit source directory after a build.

@lucaregini
thanks @gambiteer this works also for me.
Bradley Lucier
@gambiteer
I'm curious: What will you do with the interpreted compiler?
luca regini
@lucaregini
I want to study the compiler internals and document them as far as I can. This is something that I wanted to do for quite some time. Being able to step into the code helps considerably.
Bradley Lucier
@gambiteer
Cool.

I have built Gambit on Windows 10 using mingw-w64 using the Mingw-builds installer and choosing architecture: x86_64, threads: posix, exception: seh (mimicking the configuration used by Marc in Gambit’s appveyor.yml) and all seems to work but I get quite frequent access violation crashes that all point to longjmp. Any idea anyone? Any trail would be helpful I have no idea where to go
Guillaume Cartier
@gcartier
Addendum: I just saw the commit: "Use gcc __builtin_setjmp when available” on Jun 13 2020 that seems to be exactly the fix for the crashes I encounter. I will try and build using the latest Gambit and see if it fixes my crashes. Will report the results :)

With the commit "Use gcc __builtin_setjmp when available” I now have both the Mac and Windows crashing. I ended up fixing the crashes by building Gambit with —enable-cpluscplus

Hello
Can you update the README file in the repo with the latest supported SRFIs?
Right now Gambit column on the SRFI support table is incomplete because it relies on files in libs/srfi instead, which aren't present in the last tagged version.
It would be much easier to parse README for both head and tagged versions.
Erkin B Altunbaş
@erkin
I manually added details for Gambit for the time being.
Marc Feeley
@feeley

@erkin The SRFIs that are builtin are in the list returned by the R7RS procedurefeatures:

SRFI-0 SRFI-4 SRFI-6 SRFI-8 SRFI-9 SRFI-16 SRFI-18 SRFI-21 SRFI-22 SRFI-23 SRFI-27 SRFI-30 SRFI-39 SRFI-88

Gambit has some additional SRFIs implemented as modules that can be imported with import:

(import (srfi 28))  ;; Basic Format Strings
(import (srfi 41))  ;; Streams.
(import (srfi 64))  ;; A Scheme API for test suites
(import (srfi 69))  ;; Basic hash tables
(import (srfi 132)) ;; Sort Libraries
(import (srfi 158)) ;; Generators and Accumulators

I’ll look into how best to add that information to Gambit’s README.

@erkin
Thanks!
Currently, the scraper misses 16, 30 and 88.

@eval-apply
Did anyone decipher why Gambit is producing erratic segfaults while doing a make modules? Seems to compile without issue using clang 10.0.1 albeit painfully slow but failing via gcc 8.3.0
Bradley Lucier
@gambiteer
Is it true in all Gambit back-ends that a valid vector index is a fixnum?
Marc Feeley
@feeley
@gambiteer yes
Vincent Toups
@VincentToups
Gambit on Arch comes with a bunch of gambcomp-* scripts. Are they documented anywhere? Are these official ways to use the compiler?
I'm pretty interested in trying out the javascript compiler but I have had trouble finding docs
Drew Crampsie
@drewc
But, as for "docs", -target js is all that's really needed

@amirouche
@VincentToups look into https://github.com/pre-srfi/webui/

@amirouche
The documentation is not up-to-date

@gambiteer

I have a question about style: I'm trying to use case-lambda and error checking in a reasonable way, and I came up with

(define vector->array
  (let ()
    (define (five-args vec interval storage-class mutable? safe?)
      (if (not (boolean? safe?))
          (error "raw-vector->array: The fifth argument is not a boolean: "
                 vec interval storage-class mutable? safe?)
          (four-args vec interval storage-class mutable? safe?)))
    (define (four-args vec interval storage-class mutable? safe?)
      (if (not (boolean? mutable?))
          (error "raw-vector->array: The fourth argument is not a boolean: "
                 vec interval storage-class mutable?)
          (three-args vec interval storage-class mutable? safe?)))
    (define (three-args vec interval storage-class mutable? safe?)
      (if (not (storage-class? storage-class))
          (error "raw-vector->array: The third argument is not a storage-class: "
                 vec interval storage-class)
          (two-args vec interval storage-class mutable? safe?)))
    (define (two-args vec interval storage-class mutable? safe?)
      (if (not (interval? interval))
          (error "raw-vector->array: The second argument is not an interval: "
                 vec interval)
          (let ((indexer (%%interval->basic-indexer interval))
                (body-length (storage-class-length storage-class))
                (body? (storage-class-body? storage-class)))
            (cond ((not (body? vec))
                   (error "raw-vector->array: The first argument is not suitable for a body of the given storage-class: "
                          vec interval storage-class))
                  ((not (= (body-length vec) (interval-volume interval)))
                   (error "vector->array: The length of the first argument is not equal to the volume of the second: "
                          vec interval))
                  (else
                   (%%finish-specialized-array interval
                                               storage-class
                                               vec
                                               indexer
                                               mutable?
                                               safe?))))))
    (case-lambda
     ((vec interval)
      (two-args vec interval generic-storage-class (specialized-array-default-mutable?) (specialized-array-default-safe?)))
     ((vec interval storage-class)
      (three-args vec interval storage-class (specialized-array-default-mutable?) (specialized-array-default-safe?)))
     ((vec interval storage-class mutable?)
      (four-args vec interval storage-class mutable? (specialized-array-default-safe?)))
     ((vec interval storage-class mutable? safe?)
      (five-args vec interval storage-class mutable? safe?)))))

Is this reasonable? What do others do?
