Here is a template for a Bourne shell script I used that accomplishes the following: * Allows me to specify a specific version of Tcl and Tk to use (and assumes that the versions are identical). * Allows me to specify the paths to those different versions such that I insure I use those versions and not other versions that happen to reside on my system (Linux). * Sets the TCLLIBPATH environment variable to the directory or directories where extra packages are to be found. Currently set to "." which will have to be changed for your use. * Is able to be used for calling wish or tclsh. Here is the script: #!/bin/sh # -*-mode: Shell-script; indent-tabs-mode: nil; -*- uname_s=`uname -s | sed 's,[. -],_,g'` uname_r=`uname -r`; uname_n=`uname -n` OS_REV=`echo ${uname_s}_${uname_r} | sed 's,[. -],_,g'` # Customize as needed: tcl_partial_version=8.4 tcl_full_version=8.4.1 # directory above the Tcl "bin" directory: tcl_head_dir=/scratch1/tcl${tcl_full_version}/$OS_REV # directory above the Tk "bin" directory: tk_head_dir=/scratch1/tk${tcl_full_version}/$OS_REV tcl_bin=$tcl_head_dir/bin tk_bin=$tk_head_dir/bin TCL_LIBRARY=$tcl_head_dir/lib; export TCL_LIBRARY TK_LIBRARY=$tk_head_dir/lib; export TK_LIBRARY if [ ! -d $TCL_LIBRARY ]; then echo "ERROR: TCL_LIBRARY of $TCL_LIBRARY does not exist as a directory" exit 1 fi if [ ! -d $TK_LIBRARY ]; then echo "ERROR: TK_LIBRARY of $TK_LIBRARY does not exist as a directory" exit 1 fi # echo TCL_LIBRARY $TCL_LIBRARY # echo TK_LIBRARY $TK_LIBRARY # echo TCLLIBPATH $TCLLIBPATH # I do not know if modifying the PATH is a good idea, but I did it just to be safe since on my system there # are multiple versions of Tcl and Tk executables in the PATH, and I want to be sure to be using a specific version: PATH="${tcl_bin}:${tk_bin}:$PATH"; export PATH # Customize as needed: # TCLLIBPATH must be set to the path of where our packages are, and # the pkg_mkIndex has to be called to create a file in that # directory all for the sake of being able to call "package require FooBar 1.0": TCLLIBPATH=.; export TCLLIBPATH # Call tclsh for just Tcl scripts: ### tclsh${tcl_partial_version} a_script_that_uses_FooBar.tcl "$@" # Call wish for just Wish scripts: wish${tcl_partial_version} a_script_that_uses_FooBar.tcl "$@" ---- [RS]: Note that since 8.4, it is no longer necessary to keep a separate [wish] - best always call tclsh, and start Tk-ish scripts with package require Tk ----
