Re: [Emacspeak] Trying to install emacspeak on fedora 44

[Jon Pielaet <jon@xxxxxxxxxxx>]

Hi Greg,

I suspect that Fedora's default tcl package is Tcl 9, and emacspeak's speech servers and their espeak glue only work with Tcl 8.6.

Fedora still ships Tcl 8.6 as tcl8, with tcl8-devel and a TclX built for it.

Here is an example script of how I would install them and emacspeak on Fedora 44:

https://github.com/leavesofgrass/emacspeak-docker/blob/main/scripts/install-emacspeak-fedora.sh

I hope this helps.

Best,

Jon

Hello all,

I am not sure what to do here. Anyone have any suggestions?
