Install Tcl

Check suitability of a previously installed TCL.

Start tcl (type tclsh or find it using which tclsh).

[root root]% info exists tcl_platform(threaded)
1
[root root]% info patchlevel
8.5.14
[root root]%

If the first command returns anything other than 1, then tcl is not threaded. If tcl is threaded and the version is 8.5 or higher, then installing tcl from source is optional.

 (jiml) Note that you will also need compiletime stuff so you can build things against that tcl; how to get it varies according to what OS and flavor thereof you run. Personally, I don't like to permit the operating system to dictate any versions of anything or have any influence over installing/removing, so I build the whole stack (these days, not including postgres) myself.

Install Tcl

Get TCL 8.5 (or higher). Download and install TCL 8.5 from source.

If you have not installed TCL already, download the latest TCL version from Sourceforge or http://www.tcl.tk/software/tcltk/downloadnow85.html

We are installing tcl in context with aolserver to use a consistent set of libraries when more than one version may be present. Use the same directory for aolserver here, that you will be using when installing aolserver from the en:aolserver-install page.

Remember that you have to be logged in as root to issue the following commands.

[root root]# mkdir -p /usr/local/src/aolserver40r10
[root root]# cd /usr/local/src/aolserver40r10
[root src]# wget http://heanet.dl.sourceforge.net/sourceforge/tcl/tcl8.5.14-src.tar.gz
[root src]# tar xfz tcl8.5.14-src.tar.gz
[root src]# cd tcl8.5.14/unix
[root unix]# ./configure --enable-threads --prefix=/usr/local/aolserver40r10
[root unix]# make install
[root root]#
