Re: compilation error on Apple M1

[Damien Mattei]

those last years i installed guile on at least 3 mac system,without problem with read line

readline installed by homebrew ,the homebrew version seems to use gnu readline:

https://formulae.brew.sh/formula/readline

https://tiswww.case.edu/php/chet/readline/rltop.html

simply by adding that:

(use-modules (ice-9 readline))
(activate-readline)

so i surprised of this problem,

but again with homebrew it is perhaps better to install from the source too, i will try tomorrow...

i succeed in making work the first part of this :

https://www.gnu.org/software/guile/manual/html_node/C-Extensions.html

with a few modifications:

gcc `pkg-config --cflags guile-3.0` -shared -o libbessel.so -fPIC  -lguile-3.0 bessel.c

instead of:

gcc -shared -o libbessel.so -fPIC bessel.c

perhaps updating the doc

Regards,

Damien

Well, Apple also has a readline implementation that is similar but not quite the same as gnu readline.  You might need to install that along with maybe telling ./configure to use the gnu version.

Just a guess..

Actually, Guile looks for some specific symbols that the Apple lib doesn't provide, but Guile doesn't actually use those symbols.  At one time (well over 10 years ago) I got Guile to work fine with the Apple readline by removing those specific ./configure checks.

But you are probably better off by installing gnu readline.

hello Dale,

yes i had to install gsed (gnu sed):

brew install gsed




now it is almost ok

but i do not understand anymore how to make work readline and this strange error:




scheme@(guile-user)> (use-modules (ice-9 readline))
While compiling _expression_:
In procedure dlopen: file "guile-readline.dylib", message "dlopen(guile-readline.dylib, 0x0005): tried: 'guile-readline.dylib' (no such file), '/System/Volumes/Preboot/Cryptexes/OSguile-readline.dylib' (no such file), '/usr/lib/guile-readline.dylib' (no such file, not in dyld cache), 'guile-readline.dylib' (no such file), '/usr/local/lib/guile-readline.dylib' (no such file), '/usr/lib/guile-readline.dylib' (no such file, not in dyld cache)"
scheme@(guile-user)>


the second try made no error:

scheme@(guile-user)> (use-modules (ice-9 readline))
scheme@(guile-user)

but it does not work the usual way:

scheme@(guile-user)> (activate-readline)
;;; <stdin>:3:1: warning: possibly unbound variable `activate-readline'
ice-9/boot-9.scm:1685:16: In procedure raise-exception:
Unbound variable: activate-readline

Entering a new prompt.  Type `,bt' for a backtrace or `,q' to continue.
scheme@(guile-user) [1]>


https://www.gnu.org/software/guile/manual/html_node/Loading-Readline-Support.html

but it is so long time since my initial config of readline for guile that perheaps i miss a step.




Regards,

Damien

The bsd sed is different than gnu sed.  There was a few patches sent out a while ago (by RhodiumToad?) that improved building on *bsd.

I wonder if those will help?
