Pre-defined Installation Options

 

The Makefile for CLP( ) contains definitions of the environment variables CC, CFLAGS, EXEC and OPTIONS. They should be checked before installation and adjusted as follows.

• CC is just the name of the C compiler to be used to compile the CLP( ) system. It is almost always reasonable to leave this as cc, although many machines now have more efficient (and more correct) C compilers available. Information about these can be obtained from your system administrator.
• CFLAGS specifies switches of the above C compiler that need to be used. While various C compilers have their own range of switches that might have to be used to make such a large program compile and run, in most cases only the optimization level will be needed here. This will almost always be -O but higher optimization levels may be available. Also special flags may sometimes be necessary to utilize the full performance of the native floating point hardware. However, it is important to realize that many optimizing C compilers have bugs that are only triggered by compiling a large program at a high optimization level. For this reason, the first attempt to install CLP( ) should be made without invoking the C compiler's global optimizer. This usually involves just leaving the CFLAGS field blank.
• EXEC specifies the name of the CLP( ) binary to be generated. We recommend clpr.
• LIBPATH specifies the default directory for the startup file init.clpr. It should be set to the directory in which CLP( ) is installed.
• OPTIONS is used to specify the hardware and operating system. A number of predefined options are available, which often need to be used in combinations.

  BSD

  Always set if system is running Berkeley Unix, or MACH, or Ultrix. This is also to be set for NEXT machines.

  AIX

  Always set if system is running IBM's AIX operating system.

  SYS5

  This broadly indicates that some version of System V Unix is being used. Should also be used in combination with AIX flag and if the operating system is Hewlett-Packard's HP/UX.

  IBMRT

  This indicates that the system is an IBM RT/PC.

  RS6000

  This indicates that the system is an IBM RS/6000.

  HP835

  This is needed for the Hewlett-Packard RISC workstations - especially the 9000 series model 835. Note that it is not appropriate for those HP workstations based on Motorola processors.

  MIPS

  Needed for machines with MIPS CPU, such as SGI machines and the DECStation 3100.

  MSDOS

  Set for 386 or 486 PC's running MS/DOS. See the file ``DOS/README.DOS'' for details.

  OS2V2

  Set for 386 or 486 PC's running OS/2 2.0 (IMPORTANT NOTE: CLP( ) version 1.2 will not work on OS/2 1.x because that only supports 16-bit addressing). See the file ``DOS/README.OS2'' for details. bsphackfloatpenalty -Mii floatpenalty-Miii parmoderrfloatpenalty@ nextcurrboxfreelist currbox-4floatpenalty@ fltovf currboxtempboxa tempboxa @floatesphack

  So, for example an IBM RS/6000 running AIX would need the definition

Typically this value of HZ is either 60 or 100. The default value is 60 and otherwise it should be added to the OPTIONS line in the Makefile, eg. -DHZ=100, (on the RS/6000 the default is 100hz). bsphackfloatpenalty -Mii floatpenalty-Miii parmoderrfloatpenalty@ nextcurrboxfreelist currbox-4floatpenalty@ fltovf currboxtempboxa tempboxa @floatesphack
