[Pkg-tcltk-devel] need for /usr/bin/tcl

[James R. Van Zandt]

Chris -

Thanks for putting the pkg-tcl-devel list together.  
I hope you don't mind a question relating to tclx.

I am responsible for the emacspeak package which depends on the tcl
interpreter supplied by the tclx8.3 package.  There is now a tclx8.4
package, but that does not supply /usr/bin/tcl.  I am afraid the older
package will eventually be dropped, leaving no way to satisfy the
dependency.  

I tried various alternatives:

A speech server script starting

  #!/usr/bin/tcl

or

  #!/usr/bin/tclsh8.3
  load libtclx8.3.so.1

works fine.

  #!/usr/bin/tclsh8.3
  package require Tclx

segfaults even before the first utterance.

  #!/usr/bin/tclsh8.4
  load libtclx8.4.so.1

segfaults after the first utterance.

  #!/usr/bin/tclsh8.4
  package require Tclx

segfaults after the first utterance.

strace shows the segfaults are at a "select" command.

Massimo Del Zotto suggested building tcl and tclx without threads. I
did that, but still got segfaults at the same point.

I would appreciate any suggestions.
