• COMPILING AND LINKING

  In the documention that follows WEB_DIR refers to the location of Web on your system and a '?' inside a filename refers to the suffix of one of the specific Web distributions available e.g. _linux, _linux_le, or _linux_24.

  The directory: WEB_DIR/src contains Makefiles:

  These makefiles can be used to compile the source code, place the object code in an object library, link the object code with system object libraries, and create an executable binary file.

  1. Save copies of the original executables and libraries under an alternative name, e.g.

     cd WEB_DIR/src
     mv web? web?_orig
     mv web?.a web?_orig.a
     

  2. If you are compiling for 24-bit visual e.g. using Makefile_linux_24 or Makefile_linux_24_64 first you must compile the AppPlusS widget in its own directory (either: WEB_DIR/AppPlusS or WEB_DIR/AppPlusS_64, e.g.

     cd WEB_DIR/AppPlusS
     xmkmf -a ; make ;
     cd WEB_DIR/src
     

  3. Edit source directory Makefile? as necessary (e.g. change processor flags or optimization levels).
  4. Compile and /or link Web using the provided Makefiles e.g.

     make -f Makefile?
     

     If the make operation fails due to a missing header file: Xm.h then you will have to install the XWindow/Motif Development and headers files. Some Linux distributions do not install this by default, but it usually is present in the distribution.
     
     If the make operation still fails to compile or the new executable does not run contact us at the address below.

• SOME COMPILATION AND LINKING FLAGS

  -DFUNCPROTO	require function prototypes
  -O2	optimization level
  -woff	ignore enumerated warnings
  -fullwarn	list verbose warnings
  -P_SGIOSF	cpp flag for SGI byte ordering
  -DSP_SUNSP	cpp flag for selective compilation on Sun
  -DSP_NT	cpp flag for selective compilation on NT
  -app_plus	cpp flag for selective compilation for 24 bit visual
  -DWEB_24	cpp flag for selective compilation for Appplus widget
  -DWEB_BGFG	cpp flag for selective compilation with fixed color menus
  -I/usr/X11R6/include	set location of Xwindow headers

• SHARED RUN-TIME LIBRARIES

  Web requires the following shared run time libraries:

  -Xm	Motif
  -Xt	X Toolkit
  -X11	X11
  -Xmu	Window
  -m	math
