x3270 Build and Install Instructions

Vanilla X11R5 or X11R6

x3270 was developed on a Sun workstation running SunOS 4.1.3_U1 and MIT X11R5. It is set up to build and install without modifications under any complete X11R5 or X11R6 implementation.

A "complete" R5 or R6 implementation means that xmkmf and imake are configured and installed on your system, and that the Xaw and Xmu libraries and header files are installed. Some vendors (HP and IBM in particular) consider these optional software and do not always install them.

If you are running vanilla X11R5 or X11R6, then the build procedure is: 

    xmkmf		# create a Makefile
    make depend		# add dependency information
    make		# build x3270 and its fonts

x3270 requires that its fonts and app-defaults file be installed in order to run. However, a script is provided for testing a local copy of x3270 in the current directory: 

    ./dryrun		# test x3270

Once you are satisfied that x3270 is working, you can install it (as root) with the command: 

    make install

Before running x3270, you will also need to (once): 

    xset fp rehash

That's the easy way. Here are the exceptions:

Vanilla X11R4

If you are running MIT X11R4 (subject to the same definition of "completeness" above), the build procedure is almost as simple: 

    mv Imakefile.R4 Imakefile	# use the R4 Imakefile instead
    xmkmf			# create a Makefile
    make depend			# add dependency information
    make			# build x3270 and its fonts

x3270 requires that its fonts and app-defaults file be installed in order to run. However, a script is provided for testing a local copy of x3270 in the current directory: 

    ./dryrun		# test x3270

Once you are satisfied that x3270 is working, you can install it (as root) with the command: 

    make install

Before running x3270, you will also need to (once): 

    xset fp rehash

IBM RS/6000, AIX 3.2, X11R5

AIX X11R5 does not include does not include xmkmf or imake, but it includes the source code for them. If these have not been built and installed on your system (e.g., if there is no such file as "/usr/bin/X11/imake"), you must first build and install them by following the instructions in /usr/lpp/X11/Xamples/README.

Once these have been installed, you can use the standard X11R5 build procedure above.

IBM RS/6000, AIX 3.2, X11R4

AIX X11R4 does not include the Xaw libraries by default, and it does not include xmkmf at all. If the "Xample" clients and libraries have not been installed on your system (e.g., if there is no such file as "/usr/bin/X11/imake"), you must first build and install them by following the instructions in /usr/lpp/X11/Xamples/README.

Once these have been installed, you can use a simple variation on the R4 build procedure: 

    mv Imakefile.R4 Imakefile	# use the R4 Imakefile instead
    imake -DUseInstalled -I/usr/lpp/X11/Xamples/config	# replacement for xmkmf
    make depend			# add dependency information
    make			# build x3270 and its fonts

x3270 requires that its fonts and app-defaults file be installed in order to run. However, a script is provided for testing a local copy of x3270 in the current directory: 

    ./dryrun		# test x3270

Once you are satisfied that x3270 is working, you can install it (as root) with the command: 

    make install

Before running x3270, you will also need to (once): 

    xset fp rehash

HP-UX A9.01, X11R5

HP's X11R5 distribution does not include the Xaw libraries or header files. As HP's X man page says,
A number of unsupported core MIT clients and miscellaneous utilities are provided in /usr/contrib/bin. In addition, the entire core MIT distribution, compiled for Hewlett-Packard platforms, can be obtained from HP's users group INTERWORKS for a nominal fee. See the release notes for details.
What you need is the Xaw and Xmu libraries, imake, and xmkmf. Then you can follow the vanilla R5 build and install instructions.

Sun Solaris 2.3, OpenWindows Version 3.3 or Later

Surprise! Sun has given up on the xnews server and proprietary font scheme, and OpenWindows 3.3 is based on plain old X11R5. Follow the instructions for Vanilla X11R5.

However, Sun's X11 configuration files can still cause some problems. These are not x3270 problems -- they affect building any X application that uses an Imakefile.

If you see compler errors like this: 

    ucbcc: Warning: Option -Wa,-cg92 passed to ld, if ld is invoked, ignored otherwise

Then you need to to edit the "Makefile" that was produced by xmkmf and change the line that reads: 

    CCOPTIONS = -DSYSV -DSVR4 -xF -Wa,-cg92

and change it to: 

    CCOPTIONS = -DSYSV -DSVR4 -xF

If "make install" fails with the following error: 

    sh: /usr/openwin/bin/bsdinst: not found

Then edit the "Makefile" again and change the line that reads: 

    INSTALL = $(BINDIR)/bsdinst

and change it to: 

    INSTALL = /usr/ucb/install

Sun OpenWindows, Version 3.0, 3.1, or 3.2

Early versions of Sun OpenWindows use a proprietary font format that renders standard Imakefiles useless. A special Makefile is included in the x3270 distribution to handle this. (NOTE: The special Makefile must be run with Sun make; Gnu make will not work).

To build x3270: 

    make -f Makefile.openwin

If you get the following undefineds: 

   _get_wmShellWidgetClass
   _get_applicationShellWidgetClass

This is a bug in Sun's X11 libraries, and can be corrected by obtaining patches 100512-02 and 100573-03 from Sun. As a short-term workaround, there is a line in Makefile.openwin which you can uncomment.

Note: When the fonts are being compiled, the "bldfamily" program will produce output lines that look like: 

    * 3270                 ./3270.ff (Encoding: unknown)
These "unknown" messages are harmless.

x3270 requires that its fonts and app-defaults file be installed in order to run. However, a script is provided for testing a local copy of x3270 in the current directory: 

    ./dryrun		# test x3270

To install: 

    make -f Makefile.openwin install

Before running x3270, you will also need to (once): 

    xset fp rehash

Sun OpenWindows, Version 2

OpenWindows 2 does not include the the Athena Widgets (Xaw) or Xmu libraries, so x3270 cannot run under it.

Systems Based on System V, Release 4

Before running xmkmf, you must uncomment a line in the Imakefile to include the network libraries: 
  EXTRA_LIBRARIES = -lnsl -lsocket

Mixed X Environments

If you are running a mixture of X environments, such as running a Sun XNews server but using X11R5 libraries and header files, the supplied Imakefile may not work properly, because it assumes that your server and libraries are of the same type. This is not an impossible situation, just a difficult one. It generally means that you will have to build and install the fonts separately, perhaps even by hand, and you may have to install the app-defaults file by hand.

Some tools are available to help. If you need to build fonts for an XNews (Sun OpenWindows) server, but otherwise are using X11R4 or X11R5 libaries to build x3270, you can build and install OpenWindows fonts separately with the commands: 

    make -f Makefile.openwin fonts
    make -f Makefile.openwin install.fonts

Building Fonts for X Terminals

The Imakefile that comes with x3270 assumes that you plan to run the x3270 client on the same workstation as your X server. Therefore it builds fonts for that kind of X server. Compiled fonts (.snf or .pcf files) are not compatible between different servers, so if you run x3270 with its display somewhere else (such as on an X Terminal), you will need to compile the fonts for that server. It is impossible to give comprehensive instructions here; however, here is an outline for how to do it:

SCO Open Desktop 3

You will need to edit a few files in order to build under SCO Open Desktop 3.

In globals.h, remove the "#define NO_SYS_TIME_H" that is defined for sco.

In Imakefile, add: 

	EXTRA_LIBRARIES = -lnsl_s -lsocket
Also be aware that x3270 requires the Athena Widgets library, which is available from sosco.sco.com.
