! 25: =========================================================================
1.1 etheisen 26:
27: This is the distribution of "less", a paginator similar to "more" or "pg".
1.1.1.2 ! millert 28:
1.1 etheisen 29: The formatted manual page is in less.man.
30: The manual page nroff source is in less.nro.
31: Major changes made since the last posted version are in NEWS.
32:
33: =======================================================================
34: INSTALLATION (Unix systems only):
35:
1.1.1.2 ! millert 36: 1. Move the distributed source to its own directory and unpack it,
! 37: if you have not already done so.
1.1 etheisen 38:
39: 2. Type "sh configure".
40: This will generate a Makefile and a defines.h.
41: Warning: if you have a GNU sed, make sure it is version 2.05 or later.
42:
1.1.1.2 ! millert 43: The file INSTALL describes the usage of the configure program in
! 44: general. In addition, these options to configure are supported:
! 45:
! 46: --with-editor=program
! 47: Specifies the default editor program used by the "v" command.
! 48: The default is "vi".
! 49: --with-regex=lib
! 50: Specifies the regular expression library used by less for pattern
! 51: matching. The default is "auto", which means the configure program
! 52: finds a regular expression library automatically. Other values are:
! 53: posix Use the POSIX-compatible regcomp.
! 54: pcre Use the PCRE library.
! 55: regcmp Use the regcmp library.
! 56: re_comp Use the re_comp library.
! 57: regcomp Use the V8-compatible regcomp.
! 58: regcomp-local Use Henry Spencer's V8-compatible regcomp
! 59: (source is supplied with less).
! 60:
1.1 etheisen 61: 3. It is a good idea to look over the generated Makefile and defines.h
62: and make sure they look ok. If you know of any peculiarities of
63: your system that configure might not have detected, you may fix the
1.1.1.2 ! millert 64: Makefile now. Take particular notice of the list of "terminal"
! 65: libraries in the LIBS definition in the Makefile; these may need
! 66: to be edited. The terminal libraries will be some subset of
! 67: -lncurses -lcurses -ltermcap -ltermlib
1.1 etheisen 68:
69: If you wish, you may edit defines.h to remove some optional features.
70: If you wish to build a "secure" version of less (which disables all
71: features which might allow a user to do unintended things to the system
72: on which less is running), edit defines.h and define SECURE to 1.
73: If you choose not to include some features in your version, you may
74: wish to edit the manual page "less.nro" and the help page "less.hlp"
75: to remove the descriptions of the features which you are removing.
1.1.1.2 ! millert 76: If you edit less.hlp, you should run "make -f Makefile.aut help.c".
1.1 etheisen 77:
78: 4. Type "make" and watch the fun.
79:
1.1.1.2 ! millert 80: 5. If the make succeeds, it will generate the programs "less",
! 81: "lesskey" and "lessecho" in your current directory. Test the
! 82: generated programs.
1.1 etheisen 83:
84: 6. When satisfied that it works, if you wish to install it
85: in a public place, type "make install".
86:
87: The default install destinations are:
1.1.1.2 ! millert 88: Executables (less, lesskey, lessecho) in /usr/local/bin
! 89: Documentation (less.nro, lesskey.nro) in /usr/local/man/man1
1.1 etheisen 90: If you want to install any of these files elsewhere, define
1.1.1.2 ! millert 91: bindir and/or mandir to the appropriate directories.
1.1 etheisen 92:
93: If you have any problems building or running "less", suggestions,
1.1.1.2 ! millert 94: complaints, etc., you may mail to the author at markn@greenwoodsoftware.com.
1.1 etheisen 95:
96: Note to hackers: comments noting possible improvements are enclosed
97: in double curly brackets {{ like this }}.

101: =======================================================================
1.1.1.2 ! millert 102: INSTALLATION (MS-DOS systems only,
! 103: with Microsoft C, Borland C, or DJGPP)
1.1 etheisen 104:
105: 1. Move the distributed source to its own directory.
1.1.1.2 ! millert 106: Depending on your compiler, you may need to convert the source
! 107: to have CR-LF rather than LF as line terminators.
1.1 etheisen 108:
1.1.1.2 ! millert 109: 2. If you are using Microsoft C, rename MAKEFILE.DSU to MAKEFILE.
! 110: If you are using Borland C, rename MAKEFILE.DSB to MAKEFILE.
! 111: If you are using DJGPP, rename MAKEFILE.DSG to MAKEFILE.
1.1 etheisen 112:
113: 3. Look at MAKEFILE to make sure that the definitions for CC and LIBDIR
1.1.1.2 ! millert 114: are correct. CC should be the name of your C compiler and
! 115: LIBDIR should be the directory where the C libraries reside (for
! 116: Microsoft C only). If these definitions need to be changed, you can
! 117: either modify the definitions directly in MAKEFILE, or set your
! 118: environment variables CC and/or LIBDIR to override the definitions
! 119: in MAKEFILE.
1.1 etheisen 120:
1.1.1.2 ! millert 121: 4. If you wish, you may edit DEFINES.DS to remove some optional features.
1.1 etheisen 122: If you choose not to include some features in your version, you may
1.1.1.2 ! millert 123: wish to edit the manual page LESS.MAN and the help page HELP.C
1.1 etheisen 124: to remove the descriptions of the features which you are removing.
125:
1.1.1.2 ! millert 126: 5. Run your "make" program and watch the fun.
! 127: If your "make" requires a flag to import environment variables,
! 128: you should use that flag.
1.1 etheisen 129: If your compiler runs out of memory, try running "make -n >cmds.bat"
130: and then run cmds.bat.
131:
1.1.1.2 ! millert 132: 6. If the make succeeds, it will generate the programs "LESS.EXE" and
! 133: "LESSKEY.EXE" in your current directory. Test the generated programs.
1.1 etheisen 134:
1.1.1.2 ! millert 135: 7. When satisfied that it works, you may wish to install LESS.EXE and
! 136: LESSKEY.EXE in a directory which is included in your PATH.

150:
1.1.1.2 ! millert 151: 4. If you wish, you may edit defines.wn to remove some optional features.
1.1 etheisen 152: If you choose not to include some features in your version, you may
1.1.1.2 ! millert 153: wish to edit the manual page less.man and the help page help.c
1.1 etheisen 154: to remove the descriptions of the features which you are removing.
155:
156: 5. Type "make" and watch the fun.
157:
1.1.1.2 ! millert 158: 6. If the make succeeds, it will generate the programs "less.exe" and
! 159: "lesskey.exe" in your current directory. Test the generated programs.
! 160:
! 161: 7. When satisfied that it works, if you wish to install it
! 162: in a public place, type "make install".
! 163: See step 6 of the Unix installation instructions for details
! 164: on how to change the default installation directories.
! 165:

! 170: with EMX C)
! 171:

! 184:
! 185: 6. If the make succeeds, it will generate the programs "less.exe" and
! 186: "lesskey.exe" in your current directory. Test the generated programs.
1.1 etheisen 187:
188: 7. Make sure you have the emx runtime installed. You need the emx DLLs
189: emx.dll and emxlibcs.dll and also the termcap database, termcap.dat.
190: Make sure you have termcap.dat either in the default location or
191: somewhere in a directory listed in the PATH or INIT environment
192: variables.
193:
194: 8. When satisfied that it works, you may wish to install less.exe,
1.1.1.2 ! millert 195: lesskey.exe and scrsize.exe in a directory which is included in
! 196: your PATH. scrsize.exe is required only if you use a terminal
! 197: emulator such as xterm or rxvt.
! 198:
! 199:

! 214: wish to edit the manual page less.man and the help page help.c
! 215: to remove the descriptions of the features which you are removing.
! 216:
! 217: 5. Type "dmake" and watch the fun.
! 218: The standard OS-9 "make" will probably not work. If you don't
! 219: have dmake, you can get a copy from os9archive.rtsi.com.
! 220:
! 221: 6. If the make succeeds, it will generate the programs "less" and
! 222: "lesskey" in your current directory. Test the generated programs.
