Issues installing 8.4 with pthread enabled

Posted by dibya.jyoti (dibya.jyoti), 5 September 2007
I am trying to install tcl8.4.15 with --enable-pthreads on Debian. I did follwing steps :
1. downloaded from
2. copied to /usr/local/src
3. untared and run /usr/local/src/tcl8.4.15/unix/configure --enable-pthreads.
4. make
5. make test
6. make install

In my tcl script whenever I give "package require Thread" , it gives me ::
can't find package Thread
while executing
"package require Thread"
(file "./sample.tcl" line 2)

Please help me to install tcl8.4 with thread enabled.

All I can say, I'm afraid, is "I don't know"  

We get a certain proportion of questions that are so specific that very few people indeed can help ,,, and this is one of them.  Your best approach might be a Debian Mailing list if the issue is debian specific, or an approach to the people who look after the pthreads module - you should find contact details in the source.   But do check for comments about the problem in the source first, and research it thoroughly - typically such developers love INTERESTING questions but get pretty cheese off about questiosn that aren't properly researched, or where the writer demands an answer.

If you get it sorted, Jyoti, please come vback here and tell us what the answer was.

Hi Graham,
Finally I am able to do that on my Debian 2.6.18-5-686. Here is the steps for that. Now I am going to try threading with TCL. Like how to reload 20 routers parallely without wasting time for each router to complete the reloading. All the thread will continue to reload each routers separately.

Here is steps to get the Thread enabled for TCL.
Thread package ::
TCL 8.4.15 ::
Steps :: First compile TCL 8.4.15 with threading support.
Copy the tar.gz into /usr/local/src and untar it. /usr/local/src/tcl8.4.15<...>/unix
./configure --enable-threads --enable-gcc
2. make
3. make install

Then compile and install Thread patch :
1. copy the tar.gz into /usr/local/src/
2. untar it.
3. ./configure --enable-pthreads
4. make
5. make install

How to verify thread is available ?

% package require Thread

If there is any issue then it will say : can't find package Thread

Thanks for that follow up ... it makes the thread more useful for anyone else who comes this way.
