Everyone: I’m still not there, any suggestions appreciated.
Hidetoshi NAGAI,
Thanks very much for your help so far! As you can see (from the
comments
interspersed with yours, below) I’m probably out of my depth here, and I
don’t want to waste a lot of your time. Maybe I should delete
(uninstall)
Ruby, ActiveTCL, and the ktHTML packages and reinstall?
If I do that, I’d prefer not to reinstall ActiveTCL (just because of the
size
of it) and install only Ruby and the ktHTML package. I can’t
immediately
recall/find from where I downloaded the ktHTML package, there is no
version
number on the package, and the dates on the files are now (of course)
the
dates I downloaded the files, not the original dates.
The size of the tkhtml.tar.gz is 387987 bytes, and the first lines of
the
spec.html file are:
“This is a draft interface specification for the Tk HTML widget
currently
under development. Since it is still a draft, it is subject to change.
Eventually, the interface will stabilize and this interface
specification
will morph into a manual page.”
My question is, is that the latest version, or is the version in
ActiveTCL
more up-to-date?
Below (interspersed with your suggestions) are the things I’ve tried and
the
results–perhaps you or somebody else can see what I’ve done wrong.
(Or, at
some time in the fairly near future, I’ll uninstall Ruby, etc., and
start
again–it may be a week or two as I have some other things to deal with
in
the next week or so.)

I think that your tcltklib.so doesn’t load ActiveTcl library.
Please run “/usr/local/bin/ruby -r tk -e ‘p Tk::TCL_LIBRARY’”.
Probably, it shows the path your original (not ActiveTcl) Tcl/Tk directory.
Yes, it shows “/usr/lib/tcl8.4”
You may control the path with LD_LIBRARY_PATH or TCL_LIBRARY environment
variable. For example, “TCL_LIBRARY=/usr/local/ActiveTcl/lib/tcl8.4
/usr/local/bin/ruby -r tk -e ‘p Tk::TCL_LIBRARY’”.
That didn’t seem to do anything the first time I tried it, now going
back to
try again and check various things:
- I now see the following in my environment–is that what I should
see?
[rhk@s14 tkHTML]$ set | grep LIBRARY
_=‘p Tk::TCL_LIBRARY’
-
I installed ActiveTcl 8.5, so I believe the path I should use
is /usr/local/ActiveTcl/lib/tcl8.5. It exists, and contains some .tcl
files
(e.g., auto.tcl) and subdirectories (e.g., opt0.4).
-
Now I run
[rhk@s14 tkHTML]$
TCL_LIBRARY=/usr/local/ActiveTcl/lib/tcl8.5 /usr/local/bin/ruby -r tk -e
‘p
Tk::TCL_LIBRARY’
and get: “/usr/lib/tcl8.4” which looks the same as before. Is that what
I
should get?
Earlier (on the first try) I tried running irb and got no better results
for
the require ‘tclextlib/tkHTML’ statement, but I now realize I should run
irb
something like this:
TCL_LIBRARY=/usr/local/ActiveTcl/lib/tcl8.5 /usr/local/bin/irb
Let’s see how that works–nope, still the same problem:
[rhk@s14 rhk]$ TCL_LIBRARY=/usr/local/ActiveTcl/lib/tcl8.5
/usr/local/bin/irb
irb(main):001:0> require ‘tk’
=> true
irb(main):002:0> require ‘tkextlib/tkHTML’
RuntimeError: TkPackage can’t find package Tkhtml
from /usr/local/lib/ruby/1.8/tk/package.rb:86:in `require’

You can get the support status of Tk extensions on your environment
by “/usr/local/lib/ruby/1.8/tkextlib/pkg_checker.rb”.
That seems useful (now and in the future). Among other things, I see:
*LACK : tkHTML.rb : require->{}
FAIL->[[“tkextlib/tkHTML/htmlwidget”, :require_ruby_lib]]
*LACK : tkHTML/htmlwidget.rb : require->{} FAIL->[[“Tkhtml”, :package]]
Ready : tkHTML/setup.rb : require->{}
(And maybe half of the packages that scroll by are marked Ready and the
other
half marked LACK (just a guess). I’m guessing that Ready means I’m good
to
go, and LACK means there is a problem.)
Possibly, you get different result between
“/usr/local/bin/ruby /usr/local/lib/ruby/1.8/tkextlib/pkg_checker.rb”
and
“TCL_LIBRARY=/usr/local/ActiveTcl/lib/tcl8.4 /usr/local/bin/ruby
/usr/local/lib/ruby/1.8/tkextlib/pkg_checker.rb”. –
Nope, they seem the same.
<My “notes”, showing more detail–I think you can ignore these>
The results for tkHTML seem the same:
[rhk@s14 tkHTML]$
TCL_LIBRARY=/usr/local/ActiveTcl/lib/tcl8.5 /usr/local/bin/ruby
/usr/local/lib/ruby/1.8/tkextlib/pkg_checker.rb
| grep tkHTML
*LACK : tkHTML.rb : require->{}
FAIL->[[“tkextlib/tkHTML/htmlwidget”, :require_ruby_lib]]
*LACK : tkHTML/htmlwidget.rb : require->{} FAIL->[[“Tkhtml”, :package]]
Ready : tkHTML/setup.rb : require->{}
[rhk@s14 tkHTML]$
TCL_LIBRARY=/usr/local/ActiveTcl/lib/tcl8.5 /usr/local/bin/ruby
/usr/local/lib/ruby/1.8/tkextlib/pkg_checker.rb
| wc
253 1313 12046
[rhk@s14 tkHTML]$ /usr/local/lib/ruby/1.8/tkextlib/pkg_checker.rb | wc
253 1313 12046
</My “notes”, showing more detail–I think you can ignore these>
Ok, maybe because tkHTML/setup.rb is ready, I should try running that,
with
the TCL_LIBRARY path prefix:
[rhk@s14 tkHTML]$
TCL_LIBRARY=/usr/local/ActiveTcl/lib/tcl8.5 /usr/local/bin/ruby
/usr/local/lib/ruby/1.8/tkextlib/tkHTML/setup.rb
And then retry pkg_checker–no, no change in the output listed
previously
(with or without the TCL_LIBRARY prefix):
*LACK : tkHTML.rb : require->{}
FAIL->[[“tkextlib/tkHTML/htmlwidget”, :require_ruby_lib]]
*LACK : tkHTML/htmlwidget.rb : require->{} FAIL->[[“Tkhtml”, :package]]
Ready : tkHTML/setup.rb : require->{}
