tcl3270 Build and Install Instructions

To build tcl3270, type: 
    ./configure
    make
To install tcl3270 in the default install directory (/usr/local/bin), type: 
    make install

Notes on the Tcl Library

tcl3270 uses Tcl 8.4 by default. It assumes that the header file tcl.h has been installed in the directory /usr/local/include, and that the Tcl library libtcl8.4.a has been installed in the directory /usr/local/lib. If you have a different version of Tcl, or it is installed in different directories, you will need to pass additional options to the configure script.

To use a different version of Tcl, pass the --with-tcl= option to configure, specifying the other version, e.g: 

    ./configure --with-tcl=8.2
If you have the Tcl header files or libraries installed in directories other than those selected by default, you must pass these options to configure. To specify a different header file directory, put a -I option in the CPPFLAGS variable. To specify a different library directory, put a -L option in the LDFLAGS variable.  For example (using bash, ksh, or sh): 
    ./configure CPPFLAGS=-I/auto/unsupported/tcl LDFLAGS=-L/auto/unsupported/lib

  tcl3270 has not been tested with versions of tcl other than
 8.2, 8.3 and 8.4.  

 Using Extended Tcl (TclX)

  tcl3270 can also use Extended Tcl (TclX).  To use Extended
Tcl, pass the --with-tclx option to configure, e.g.:  

    
  
./configure --with-tclx

  

  Note that Extended Tcl releases tend to lag behind standard Tcl releases;
 when this was written, the current release of Extended Tcl was 8.2. 
 So, to build tcl3270 with Extended Tcl 8.2, you must have Tcl 8.2
installed on your system, and you must explicitly specify the version of
TclX with configure:  

    
  
./configure --with-tclx=8.2

  

    

 Notes for Solaris 2.x and Sun's C Compiler

  Do not use Sun's BSD-compatibility compiler, /usr/ucb/cc. This
is good advice in general, but in particular, tcl3270 will not build
with it. You must have a directory containing gcc (preferred) or
Sun's standard compiler in your $PATH ahead of /usr/ucb.  

 Summary of configure Options

  The tcl3270 configure script accepts the following options:
 

    


  
     

  --help
   Print a help message.
  

   

  --prefix=prefix
   Install architecture-independent files under prefix (defaults
 to /usr/local)
  

   

  --exec-prefix=eprefix
   Install architecture-dependent files (executables) under eprefix
 (defaults to same as prefix)
  

   

  --bindir=dir
   Install user executables (tcl3270) in dir (defaults
to        eprefix/bin)
  

   

  --sysconfdir=dir
   Install configuration files (character sets) in dir/x3270
 (defaults to prefix/etc).
  

   

  --with-tcl=version
   Use a different version of the Tcl library. The default is 8.4.
  

   

  --with-tclx 

       --with-tclx=version		
   Use the Extended Tcl library. The TclX library must be the same version
 as the Tcl library. 

 If an explicit version is specified, this changes the Tcl library
version as well.		
  

   

  --disable-ansi
   Leave out NVT (ANSI) support. 

 Note that NVT support is required for TN3270E support.		
  

   

  --disable-apl
   Leave out APL character support.
  

   

       --enable-dbcs

       		
       Build in DBCS (Double Byte Character Set) support.

       		
     

          

  --disable-ft
   Leave out IND$FILE file transfer support.
  

   

  --disable-local-process
   Leave out local process (connecting to "-e shell_command")
support.        

 This will be automatically disabled if the local system does not support
the       forkpty() library call.		
  

   

  --disable-printer
   Leave out printer session (pr3287) support.
  

   

       --disable-ssl

       		
       Leave out SSL (Secure Sockets Layer) support.  SSL
 support requires the OpenSSL library.

       		
     

     

       --with-ssl=dir

       		
       Specify the directory where the OpenSSL library is
 installed.

       		
     

     

  --disable-tn3270e
   Leave out TN3270E support.
  

   

  --disable-trace
   Leave out tracing support.
  

     
   


    

Leaving out all of the optional features will result in a smaller binary.
