1) Check if "make install.libs" has been done when STk was installed.

2) Configure

   ./configure

   Default configuration will compile the package with options CC and
   CFLAGS used for the compilation of Stk. You can change CFLAGS typing,
   for example:

   CFLAGS="-g" ./configure'

   Default configuration will install the package's files and
   look for STk package in /usr/local/bin, /usr/local/lib.
   You can specify an installation prefix other than /usr/local
   by giving `configure' the option `--prefix=PATH', and an other
   STk package prefix with the  option `--exec_prefix=PATH'

3) Compiling

   Type make

4) Installation

   Check your DISPLAY variable and type "make install". 
   Check paths in the window and  click on "Save" to 
   generate an xxl executable file.
  
Now two possibilities:

	1) You have dynamic loading. Nothing to do. You can run xxl.
	
	2) You have static loading. Edit <STK_SRC_PATH>/Src/userinit.c file
           and insert the following lines in the STk_user_init function:

	  #ifdef USE_TK
	     STk_init_libxxl();
          #endif

          Then you need to re-compile and link STk with the
          librarie libxxl.a installed in {prefix}/lib/xxl/{version}/
          With your re-compiled stk, you can now run xxl.

xxl-2.1.2 has been correctly installed on:

        - Linux (RedHat, Debian), Solaris 2.6, HPUX 9.05; and normally can run
          on all STk platforms.
