$! BUILD_ZIP.COM $! $! Build procedure for VMS versions of Zip. $! $! last revised: 2007-03-15 SMS. $! $! Command arguments: $! - suppress help file processing: "NOHELP" $! - suppress message file processing: "NOMSG" $! - select link-only: "LINK" $! - select compiler environment: "VAXC", "DECC", "GNUC" $! - select large-file support: "LARGE" $! - select compiler listings: "LIST" Note that the whole argument $! is added to the compiler command, so more elaborate options $! like "LIST/SHOW=ALL" (quoted or space-free) may be specified. $! - supply additional compiler options: "CCOPTS=xxx" Allows the $! user to add compiler command options like /ARCHITECTURE or $! /[NO]OPTIMIZE. For example, CCOPTS=/ARCH=HOST/OPTI=TUNE=HOST $! or CCOPTS=/DEBUG/NOOPTI. These options must be quoted or $! space-free. $! - supply additional linker options: "LINKOPTS=xxx" Allows the $! user to add linker command options like /DEBUG or /MAP. For $! example: LINKOPTS=/DEBUG or LINKOPTS=/MAP/CROSS. These options $! must be quoted or space-free. Default is $! LINKOPTS=/NOTRACEBACK, but if the user specifies a LINKOPTS $! string, /NOTRACEBACK will not be included unless specified by $! the user. $! - select installation of CLI interface version of zip: $! "VMSCLI" or "CLI" $! - force installation of UNIX interface version of zip $! (override LOCAL_ZIP environment): "NOVMSCLI" or "NOCLI" $! - select BZIP2 support: "IZ_BZIP2=dev:[dir]", where "dev:[dir]" $! (or a suitable logical name) tells where to find "bzlib.h". $! The BZIP2 object library (LIBBZ2_NS.OLB) is expected to be in $! a "[.dest]" directory under that one ("dev:[dir.ALPHAL]", for $! example), or in that directory itself. $! $! To specify additional options, define the global symbol $! LOCAL_ZIP as a comma-separated list of the C macros to be $! defined, and then run BUILD_ZIP.COM. For example: $! $! $ LOCAL_ZIP == "VMS_IM_EXTRA" $! $ @ [.VMS]BUILD_ZIP.COM $! $! Valid VMS-specific options include VMS_PK_EXTRA and VMS_IM_EXTRA. $! See the INSTALL file for other options. (VMS_PK_EXTRA is the $! default.) $! $! If editing this procedure to set LOCAL_ZIP, be sure to use only $! one "=", to avoid affecting other procedures. For example: $! $ LOCAL_ZIP = "VMS_IM_EXTRA" $! $! Note: This command procedure always generates both the "default" $! Zip having the UNIX style command interface and the "VMSCLI" Zip $! having the CLI compatible command interface. There is no need to $! add "VMSCLI" to the LOCAL_ZIP symbol. (The only effect of $! "VMSCLI" now is the selection of the CLI style Zip executable in $! the foreign command definition.) $! $! $ on error then goto error $ on control_y then goto error $ OLD_VERIFY = f$verify( 0) $! $ edit := edit ! override customized edit commands $ say := write sys$output $! $!##################### Read settings from environment ######################## $! $ if (f$type( LOCAL_ZIP) .eqs.
