TCP/IP considerations

Some of the CERNLIB modules require TCP/IP socket libraries. The list of these modules is defined by the symbol need_tcp in makepack.com. At the time of writing, this is defined as shown below.

List of modules requiring TCP/IP

$ need_tcp = ".ZFTP.ZSERV.PAWM.PAWPP.PAWSERV.TELNETG.SYSREQ.FATMEN."

The CERNLIB installation procedures attempt to chose the correct version of TCP/IP and act accordingly. This is done in the command file f$tcpip.com as follows:

Determining the TCP/IP version

$ If F$TRNLNM("TWG$ETC").nes.""     Then tcpip_var="Wollongong WINTCP"
$ If F$TRNLNM("MULTINET").nes.""    Then tcpip_var="MultiNet TCPIP"
$ If F$TRNLNM("UCX$NETWORK").nes."" Then tcpip_var="UCX TCPIP"

If you do not have one of these systems installed, then you will need to modify f$tcpip.com and makepack.com accordingly.

There are 3 areas that might require modification:

1. The selection of the appropriate include files.
2. Definitions for the C preprocessor.
3. The appropriate options file for linking.

Selecting the appropriate include files

$ If pack.eqs."TELNETG"
$ Then If tcppg.eqs."_W"
$      Then TCPDIR="TWG$TCP:[netdist.include"
$           assign/user_mode 'TCPDIR'],'TCPDIR'.sys],'TCPDIR'.net],-
                             'TCPDIR'.netinet],sys$library vaxc$include
$           assign/user_mode 'TCPDIR'.net]     net
$           assign/user_mode 'TCPDIR'.arpa]    arpa
$      Endif
$      If tcppg.eqs."_M"
$      Then TCPDIR="MULTINET_ROOT:[Multinet.include"
$           assign/user_mode 'RDIR'.src.cfs.cspack] arpa
$      Endif
$      If tcppg.eqs."_U"
$      Then TCPDIR="UCX??"
$      Endif
$           assign/user_mode 'TCPDIR'.sys]     sys
$           assign/user_mode 'TCPDIR'.netinet] netinet
$ Endif

Definitions for the C preprocessor

$      If tcppg.eqs."_W"   Then cco=cco+"/DEF=TWG"
$      If tcppg.eqs."_M"   Then cco=cco+"/DEF=TGV"
