Actually, I'm not sure that information is correct. I'm running on
Fedora 44 and dnf shows there is a tclx package. However, I did have to
change the shell shebang to
#!/usr/bin/tclsh8
I have the following tcl related packages installed from dnf
tcl.x86_64 1:9.0.2-1.fc44
tcl8.x86_64 1:8.6.17-2.fc44
tcl8-devel.x86_64 1:8.6.17-2.fc44
tclx.x86_64 8.4.0-52.fc44
The most common cause of errors when it comes to building the speech
servers are minor naming inconsistencies across linux distributions or
operating systems. For example, tclsh8 for the tcl shell name instead of
just tclsh or slight differences in shared library names. The ldd
command can help identify missing shared libs, as can using tools like
find ro the fd utility.
