beep and laptops

[galaxysite]

Hi,

When finding bug in some program, we touch "beep": mse-org/mseide-msegui#24

Beep show error on laptop:

Fstat failed. Errno : 2
But in my system /dev/input/by-path there are only those:
Screenshot_2024-10-26_14-24-48
$ beep
beep: Error: Could not open any device
PS: I have a laptop, maybe pcspkr cannot be installed.

Maybe add to beep My fast-playing low-level code from: https://github.com/galaxysite/gorg64_spkplay and possible music playing from binary files for x86* architecture ?

Did you test it for laptop (usually they dont have pc speaker output in the mother board)?
I see in your description that Root priveleges are needed, is it still so?
I will test it asap on my laptop.

For msegui (and fpc too) it is a known problem, beep() does not work on lot of Linux laptop.
The work-around that I use is to use libasound.so

Hello.
I did compile spkr-beep but at runing on a XUbuntu 22.04 laptop Lenovo IdeaPad i5 there is that error:

Without set uid by root system not give access to I/O (function ioperm fails and "in" operation blocked).

If not working sudo need su.

gdb not have root access.

[fredvs]

In XUbuntu su does not work, the equivalent is sudo -i

fred-IdeaPad:~# sudo -i

[galaxysite]

sudo -i ?
May be... But after sudo -i who say chown ?

Need rights:
ls -l ./gorg64_spkplay
-rwsr-xr-x 1 root root 17544 ноя 2 20:57 ./gorg64_spkplay

[fredvs]

root@fred-IdeaPad:~#  ls -l /home/fred/gorg64_spkplay-main/gorg64_spkplay
-rwsr-xr-x 1 root root 1183448 nov  2 18:30 /home/fred/gorg64_spkplay-main/gorg64_spkplay

[galaxysite]

1183448 strange numbers. But the rest is correct. Maybe it's a feature of Ubuntu?
And then run.

[galaxysite]

I update https://github.com/galaxysite/gorg64_spkplay and GORG: http://soft.self-made-free.ru/GORG64_283.tar.xz

Added functions getuid/geteuid and setuid. This might improve clarity at startup and add some features.

[fredvs]

I update https://github.com/galaxysite/gorg64_spkplay
