[Chicken-users] [ANN] CHICKEN 5.0.0 release candidate 1 available

[Jérémy Farnaud]

Hello, here is my report for the testing of this version of CHICKEN on 
my Apple computer:


Operating system: macOS High Sierra (version 10.13.6)
Hardware platform: x86_64-apple-darwin17.7.0
C Compiler: Apple LLVM version 9.1.0 (clang-902.0.39.2)
Installation works?: yes
Tests work?: yes (see below)
Installation of eggs works?: yes

macOS and Xcode are up-to-date as of today. I use MacPorts but for this 
test I put it somewhere inaccessible to verify that CHICKEN works 
correctly without it.


Tests work only after installing CHICKEN. This is because the 
environment variable DYLD_LIBRARY_PATH isn’t propagated to children 
processes so the libchicken.dyld must be in a place where libraries are 
looked for by default. This is a security measure added to macOS some 
years ago.


Thanks for your hard work!

This is really impressive, especially if you see how little code is
needed for it!

Hi all,
and sorry about the late response on this one.

On my main Arch Linux, everything I tested has worked except building
statically against `check-errors` (ticket 1506
).

Operating system: Arch Linux
Hardware platform:  x86-64
C Compiler: GCC 8.2.0
Installation works?: yes
Tests work?: yes
Installation of eggs works?: yes

I also tested this on a win10 with make PLATFORM=mingw-msys install check:

Operating system: Win10
Hardware platform:  x86-64
C Compiler: GCC 8.2.0 (rev1 msys2)
Installation works?: yes
Tests work?: yes
Installation of eggs works?: yes

Note that I had to install the "diff" tool to make the check succeed.
Here's a summary of the problems I encoutered with C5rc1 on Windows 10:

- when linking statically, csc is looking for ".o" files (Kooda is looking
into this I think) , improper patch here

- pathname wierdness, see this paste

- generated .install.bat file produces copy syntax error (see this
paste

)

Apart from these minor glitches, the CHICKEN 5 experience has been
wonderful.

I wanted to try static linking with CHICKEN 5 and this is the result, a
poor man's TeamViewer:

This is the memory-mapped-files egg, which is a dependency of spiffy.
The MAP_ANON definition is marked as deprecated on GNU systems in favour
of MAP_ANONYMOUS, but other systems still hang on to MAP_ANON, sometimes
offering an alias as MAP_ANONYMOUS.  I've now changed it so that if
MAP_ANONYMOUS is undefined but MAP_ANON is defined, it is made an alias.

I've published a new release, which should appear on the egg servers shortly.

Cheers,
Peter

I should further note that yes, these are quite old OS and compiler

[kooda]

Hi there! Here are some tests results. :D

Operating system: Devuan unstable, glibc 2.27
Hardware platform: x86-64
C Compiler: GCC 8.2.0
Installation works?: yes
Tests work?: yes
Installation of eggs works?: yes (spiffy)

Operating system: Alpine Linux edge, musl-libc 1.1.19
Hardware platform: arm
C Compiler: GCC 6.4.0
Installation works?: yes
Tests work?: yes
Installation of eggs works?: yes (spiffy)


Little cross compilation test:

- Building a toolchain, on the first system (Devuan x86-64), for the
second system (Alpine ARM): works

- Building a static hello world for ARM on x86-64: works

- Building spiffy (and its dependencies) with the cross toolchain: works

- Building a simple static web server binary for ARM on x86-64: works

- Running both static binaries on the target system: works!! \o/

Just got a hint of warning from glibc because it requires the dynamic
library at runtime on the target system for some functions, but it
worked anyways!

Hi all,

I also took some time to test on an old Hurd VM I had lying around.

Operating system: Debian GNU/Hurd 0.9 (Mach 1.8+git20171101)

Re: [Chicken-users] [ANN] CHICKEN 5.0.0 release candidate 1 available

[Peter Bex]

Hi all,

I tested on Haiku.

Operating system: Haiku "Walter" revision hrev50904
Hardware platform: x86
C Compiler: GCC 5.4.0
Installation works?: yes
Tests work?: no
Installation of eggs works?: no

I ran into some trouble with a few eggs, which I've fixed since.

I've also posted two patches for CHICKEN core to chicken-hackers.
These add a workaround for Haiku's broken stat(), which caused the
core tests to fail, and a fix for chicken-install's (platform ...)
clause, which caused some trouble getting the memory-mapped-files
egg to install correctly.

Cheers,
Peter

I have just ported linenoise to chicken 5. It should be available
via chicken-install soonish.  Can you give it a try?

Thanks,

Hi Peter,
That explains a lot. I see my favourite egg is also not ported: linenoise.

Works well. Thanks.

Installed the following eggs without issue: srfi-1, srfi-13, srfi-14,
srfi-69.

Chicken 5 is a lot closer.

Thank you.

Hi Claude,

The format egg has not yet been ported to CHICKEN 5, so that's why
it cannot be installed.

There is no "time" unit.  In general, you should not be dealing with
units.  In CHICKEN 4 that's sometimes required when building statically,
but in CHICKEN 5 that should always never be necessary.

You'd need to (import (chicken time posix)), I think.  That should
take care of all the dependencies for you.

Good afternoon,

Operating system: Ubuntu 18.04.1 LTS
Hardware platform: x86_64 (AMD A8-7600)
C Compiler: gcc 7.3.0
Installation works?: yes
Tests work?: yes
Installation of eggs works?: fails to install 'format'

Server error:
Error: [Server] no such extension or version

I must be missing something. Could the previous installation of Chicken

Building a simple time stamp program fails.
csc timestamp.scm
./timestamp > prologue.scm
Error: unbound variable: command-line-arguments
Call history:
timestamp.scm:70: command-line-arguments  <--
That should be in process-context which is included. Add this and try again.

timestamp.o: In function `f_154':
timestamp.c:(.text+0x612): undefined reference to

collect2: error: ld returned 1 exit status


Removing the offending call and the declaration reveals another issue: it
cannot find seconds->local-time. So, I added this.
(declare (uses time))
Does not work.
timestamp.c:(.text+0x5f3): undefined reference to `C_time_toplevel'
Then I added this.
(declare (uses time posix))
Same error.

I have not worked with Chicken is several months. Am I missing something
obvious?

Thank you.

[Chicken-users] [ANN] CHICKEN 5.0.0 release candidate 1 available

[Peter Bex]

Hello everyone,

After many years of development, we are happy to announce the first
release candidate of the upcoming CHICKEN 5.0.0.  This represents the
largest change in CHICKEN since the 4.0.0 release.

Most importantly, we have completely overhauled the module layout so
that it should make more sense where each identifier is located.
For a quick overview of where things are, see the page we used for
discussion of these changes:
https://wiki.call-cc.org/core-libraries-reorganization

The manual has of course also been updated to reflect these new modules:
https://wiki.call-cc.org/man/5/Included%20modules

Other notable features are:
- Full numeric tower
- A new declarative egg description format for chicken-install
- Improved support for static linking (eggs are now also compiled statically)
- "Deployment" mode has been dropped as it was less portable and reliable
  than static linking.
- Builds are fully bit-for-bit reproducible (for core, but user code too)
- Random numbers now use a better PRNG than libc rand() (namely, WELL512)
- Core has gone on a diet: several libraries have been moved to eggs, like
   srfi-1, srfi-13, srfi-14, srfi-18, srfi-69, and several other things.

The (very long!) complete list of changes since version 4.13.0 is
available here: https://code.call-cc.org/dev-snapshots/2018/08/11/NEWS

CHICKEN 5.0.0rc1 is now available at this location:
https://code.call-cc.org/dev-snapshots/2018/08/11/chicken-5.0.0rc1.tar.gz

The SHA256 sum of that tarball is
fb8af147e7965761dd212b53162b181d4c9473906fd889e719c71624bca65957

Please give it a test and report your findings to the mailing list.

Here's a suggested test procedure:

  $ make PLATFORM= PREFIX= install check
  $ /bin/chicken-install spiffy

If you want to build CHICKEN with a compiler other than the default one,
just use C_COMPILER= (e.g., C_COMPILER=clang) on the make
invocation.

Of course, feel free to explore other supported build options (see the
README file for more information) and actually use CHICKEN 5.0.0rc1 for
your software.  The tireless CHICKEN team has been busy porting eggs to
CHICKEN 5 already, so you will find that many eggs you've been using have
already been ported.  Check out the ever-growing list at
https://wiki.call-cc.org/chicken-projects/egg-index-5.html

If you want to port your code to CHICKEN 5, you'll note the number of
changes are so large that it can be overwhelming.  That's why we've
written up a porting guide to help you get your code over to the new
version: https://wiki.call-cc.org/porting-c4-to-c5
Please feel free to add to the guide if you run into problems that aren't
yet addressed on this wiki page.

If you can, please let us know the following information about the
environment you tested the RC tarball on:

Operating system: (e.g., FreeBSD 11.1, Debian 9, Windows 10 mingw-msys under 
mingw32)
Hardware platform: (e.g., x86, x86-64, PPC)
C Compiler: (e.g., GCC 6.4.0, clang 5.0.0)
Installation works?: yes or no
Tests work?: yes or no
Installation of eggs works?: yes or no

Thanks in advance!

The CHICKEN Team
