Tcl Source Code

Here is a patch that gets rids of the only
undefined symbol in the Thread package.
This is important since the undefined symbol
makes it *very* difficult to load the Thread
package into another executable that has
also loaded Tcl dynamically.

I ran into this problem while testing out
Tcl Blend. The error message I was seeing
looked like this:

Exception in thread "main" tcl.lang.TclException:
couldn't load file
"/share/tcljava/build/thread/libthread2.4g.so":
/share/tcljava/build/thread/libthread2.4g.so: undefined
symbol: tclEmptyStringRep


After much poking around and reading of man
pages for dlopen, I found the problem. The
Thread package must be self contained in
order to work correctly. The package already
takes care of this with a little hack for
Windows. Thing is, this same hack is also
needed under Linux. My patch makes that
change. I am also going to include a testing
program that I created to test shared lib
loading using dlopen.

Oh, sorry, I somehow missed that. 
But where did you leave the ChangeLog message?
I was not able to find it. Or am I really blind?

Humm, you did not use the ChangeLog entry
I sent in. Since mine was more descriptive,
I went ahead and put it into the ChangeLog.

Updated in HEAD. 
Thanks!
