libgfortran on Debian #15

Closed kengruven closed 1 year ago

kengruven commented 1 year ago

I installed "sci" on Racket just now, and it fails to load:

; ffi-lib: could not load foreign library
;   path: libgfortran.so.3
;   system error: libgfortran.so.3: cannot open shared object file: No such
;     file or directory

Looking at flomat.rkt (which I found via issue #8), it looks like it's configured to use libgfortran 3 on Debian. I'm using Debian stable, which has libgfortran 5. (I don't know how old libgfortran 3 is, but probably pretty old -- Debian "buster" in 2019 had libgfortran 4.)

(Also, I'm not an Arch Linux user, but I searched on archlinux.org just now and the current gcc provides "libgfortran.so=5-64". Maybe it's time to default to libgfortran 5. Is anyone still shipping libgfortran 3?)

Thanks!

@kengruven Thanks for the report.

For now I added a line to look for version 5 when using Debian. I have alerted the package server at pkgs.racket-lang.org that there is an update.

Can you test that it works?

kengruven commented 1 year ago

I'd be happy to test it. It looks like I have to wait for the server to respond to your update -- maybe on Sundays?

soegaard commented 1 year ago

I think, an raco update sci ought to fetch the latest version even if the server haven't caught up yet. But sunday is fine.

kengruven commented 1 year ago

Even uninstalling and reinstalling it didn't help, before. But the server has caught up, and today it works. Thank you!
