Web Compilation and Linking on Linux

• EXECUTABLES

  Executable	Optimal byte-ordering	Visual	Makefile	Compiler	Notes
  web_linux_24	Big-endian	24 bit DirectColor	Makefile_linux_24	gcc	32 bit AMD or Intel
  web_linux_24_64	Big-endian	24 bit DirectColor	Makefile_linux_24_64	gcc	64 bit AMD or Intel

• 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_24 or _linux_24_64.

  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. Edit source directory Makefile? as necessary (e.g. change processor flags or optimization levels).
  3. 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.
     
     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	Our cpp flag for SGI byte ordering
  -DSP_SUNSP	Our cpp flag for selective compilation on Sun
  -DWEB_BGFG	Our cpp flag for selective compilation for 24 bit visual
  -I/usr/X11R6/include	Set location of Xwindow headers

• SHARED RUN-TIME LIBRARIES

  When we compile Web requires the following shared run time libraries:

  -Xmu	Misc. X11
  -Xt	X Toolkit
  -X11	X11
  -m	Math
  -Xm	Motif
  -Xp	Motif

  Our Makefiles specify static linkage versus the Motif libraries.
