Public bug reported:
When running wavesurfer in Ubuntu 16.04 I get:
Error in startup script: can't find package snack 2.2
while executing
"package require snack 2.2"
(file "/usr/share/tcltk/wavesurfer/wsurf/wsurf.tcl" line 9)
invoked from within
"_source /usr/share/tcltk/wavesurfer/wsurf/wsurf.tcl"
("uplevel" body line 1)
invoked from within
"uplevel _source $args"
(procedure "source" line 5)
invoked from within
"source /usr/share/tcltk/wavesurfer/wsurf/wsurf.tcl"
("package ifneeded wsurf 1.8" script)
invoked from within
"package require -exact wsurf $version"
(file "/usr/share/tcltk/wavesurfer/app-wavesurfer/wavesurfer.tcl" line 2578)
The problem:
The package wavesurfer depends on version 8.5 of tcl-tk and on snack. On Ubuntu
16.04 the default version of tcl-tk (and wish) is 8.6. Version 8.5 can be
installed manually with
sudo apt-get install tcl8.5
Unfortunately, libsnack will only work in tcl-tk (and wish) version 8.6.
Example:
> wish
% puts $tcl_version
8.6
% packa req snack
2.2
> wish8.5
% puts $tcl_version
8.5
% packa req snack
can't find package snack
Same is also valid for tclsh and tclsh8.5.
Easy fix for wavesurfer:
Add the following line to the start-up script (/usr/bin/wavesurfer):
-------------
#!/bin/sh
export TCLLIBPATH=/usr/lib/tcltk/snack2.2
exec /usr/share/tcltk/wavesurfer/app-wavesurfer/wavesurfer.tcl "$@"
-------------
Better solution:
Modify the snack package so that snack works regardless what version of tcl-tk
is used.
Another better solution:
make the wavesurfer package depend on tcl-tk 8.6 instead of 8.5 (this avoids
installing two versions of tcl-tk)
Affected packages:
- wavesurfer
- tcl-snack
- tcl8.5
