wish installer.tclIt pops up a GUI (if Tk is available) which will guide you through the installation. You can get info about valid command line switches for the installer by running:
tclsh installer.tcl -helpTesting if Tcllib worksFire up your default tcl interpreter. Try this (or to require any of the other packages):
% package require nmeaIf it works and returns the version number of the returned package, you installed Tcllib correctly. If it does not work, check your auto_path variable like this:
% set auto_pathIt has to contain the parent directory of the directory into which you installed the packages, or the install directory itself. If it is missing, you have to add it to your auto_path in your scripts.
% lappend auto_path /path/to/tcllib/installdirUpgrading an existing installationHow do you upgrade the ActiveTcl version? Do you take the defaults the installer gives you or do you find where the current version is and replace that?You can happily install multiple tcllib versions in parallel. All packages use version numbers so if you don't use package require -exact in your scripts you get the latest compatible version automatically. So if you have for instance an ActiveTcl install, you simply accept the installer defaults (run the installer with your tclsh from ActiveTcl, so it picks up the right auto_path) and install in parallel. If you are concerned about disk space you can simply delete the older tcllib directory and examples from your installation.There may be some unexpected and unwanted side effects if a package versions changes from major version (1.x to 2.x for example) indicating an API change. This happend with the md5 package, which is provided as an 1.x and 2.x version. If your code simply uses package require md5 you get the latest version, which is 2.x, which may break scripts expecting the older 1.x API. Simple fix is to change the package require to package require md5 1.
DiscussionsLV Can anyone address why 64 bit systems need a newer Tcl? Is it because Tcl itself has problems before 8.4 on 64 bit machines?schlenk Yes. As far as i remember there are some packages like MD5 etc., which don't work correctly on 64-bit systems with a pre-8.4 Tcl, but i don't rememeber the details, must be in the bugtracker.RLH 2006-10-05: Wierd on OSX the defaults are kind of strange. It comes up with /System/Libray/bin to install any executables? That should default to somewhere on the /usr path (preferably /usr/local/bin). I guess I will have to find where tcllib1.8 is hiding.schlenk Please file a bug report, when the installer does something strange. Category Installer.
