********************************************************
XOTcl Compilation Guide (Unix)
********************************************************

Note, that there is a file "COMPILE.win" describing Windows compilation.
Read this file, if you plan to build XOTcl under Windows. 

First, you have to get the necessary sources: 
  - Before you can start, you have to get the full sources of
  XOTcl. These are packed in a tar.gz file, like xotcl-XXXXX.tar.gz,
  and they are available from:

        http://www.xotcl.org

  - To compile XOTcl the sources of Tcl (and optionally Tk) are
  needed. Tcl (and optionally Tk) must be installed properly. You get
  the Tcl/tk sources from:
  
        www.tcl.tk
  
  The best is to unpack and compile Tcl (and optionally Tk) in the
  same directory as XOTcl, so that XOTcl's configure can find it
  automatically. For compilation instruction see Tcl's documentation.


The following steps have to be performed in order to 
build XOTcl:

  1) untar XOTcl in a directory of your choice by using one of:

        gunzip < xotcl-XXXXX.tar.gz | tar -xvf -

     or on some systems:
  
        tar xvfz xotcl-XXXXX.tar.gz
     

  2) run configure by issuing in the unix directory:

        cd xotcl*
        ./configure

     on some platforms (e.g. under Windows Environment with 
     CygWin) you may have to type in "sh configure" explicitly.

     If you have Tcl, Tk, and XOTcl built in your home directory 
     and you want to install in standard locations, a simple configure 
     without arguments should be sufficient. You
     can avoid searching/override the settings with 
     the follwoing switches:

     --prefix=DIR                 Place where lib/packages are 
                                  to be installed (default: /usr/local)
     --exec-prefix=DIR            Place where xotclsh/xowish
                                  are to be installed (default: /usr/local)
     --with-actiweb               Build Actiweb packages as well (sdbm, expat)
                                  (per default deactivated)
     --with-xotclsh               Build xotclsh (per default deactivated)
     --with-xwish                 Build xowish (per default deactivated)
     --with-gdbm=GDBM_INCLUDE_DIR,GDBM_LIB_DIR
                                  absolute path to gdbm.h and optionally 
                                  the path to the gdbm library. The directory infos
                                  may be omitted
     --with-tcl=DIR               Where to find a compiled Tcl version, i.e.
                                  where to find tclConfig.sh
                                  Note that you need a source built of 
                                  Tcl (including generic/tclInt.h)!
     --with-tk=DIR                Where to find a Tk version, i.e.
                                  where to find tkConfig.sh. An installed 
                                  version is sufficient. It must be the same 
                                  Tk version as the version of the used Tcl.
     --with-tk-include=DIR        directory containing the public Tk header files
     --with-all                   Turns on all options (actiweb, gdbm, 
                                  xotclsh, xowish)

     NOTE: the directories specified by DIR should not be addressed relatively: 
           be sure to use only absolute path names 
           (those starting with "/") only.

     NOTE: Tcl (and Tk if you build xowish) have to be installed. You
           require a Tcl source build (of the same version as installed)
           as well.

     Example:
     
     ./configure --prefix=/usr --exec-prefix=/usr --with-all --enable-threads

  3) now you can make XOTcl and the configured packages with

        make

     which should be actually a GNU make (sometimes called gmake).

     There are a couple of compiler options, that can make the compiled
     binary faster. On a Pentium 4 PC under Linux, i would recommend 
     to compile with

        make CFLAGS_DEFAULT='-O3 -mcpu=i686 -Wall -fomit-frame-pointer'

  4) install with:

        make install


  If you only want to build/install xotcl/xowish without packages 
  you can switch to xotcl-XXX directory and do there:

        ./configure
        make
        make install

  You can test XOTcl by switching to the src directory and by running:
 
        make test


Good Luck!
