Move the distributed source to its own directory and unpack it, 3760786Sps if you have not already done so. 3860786Sps 3960786Sps2. Type "sh configure". 4060786Sps This will generate a Makefile and a defines.h. 4160786Sps Warning: if you have a GNU sed, make sure it is version 2.05 or later. 4260786Sps 4360786Sps The file INSTALL describes the usage of the configure program in 4460786Sps general. In addition, these options to configure are supported: 4560786Sps 4660786Sps --with-editor=program 4760786Sps Specifies the default editor program used by the "v" command. 4860786Sps The default is "vi". 49170256Sdelphij 5060786Sps --with-regex=lib 5160786Sps Specifies the regular expression library used by less for pattern 5260786Sps matching. The default is "auto", which means the configure program 5360786Sps finds a regular expression library automatically. Other values are: 5460786Sps posix Use the POSIX-compatible regcomp. 5560786Sps pcre Use the PCRE library. 5660786Sps regcmp Use the regcmp library. 5760786Sps re_comp Use the re_comp library. 5860786Sps regcomp Use the V8-compatible regcomp. 5960786Sps regcomp-local Use Henry Spencer's V8-compatible regcomp 6060786Sps (source is supplied with less). 61161475Sdelphij --with-secure 62161475Sdelphij Builds a "secure" version of less, with some features disabled 63161475Sdelphij to prevent users from viewing other files, accessing shell 64161475Sdelphij commands, etc. 6560786Sps 66170256Sdelphij 6760786Sps3. It is a good idea to look over the generated Makefile and defines.h 6860786Sps and make sure they look ok. If you know of any peculiarities of 6960786Sps your system that configure might not have detected, you may fix the 7060786Sps Makefile now. Take particular notice of the list of "terminal" 7160786Sps libraries in the LIBS definition in the Makefile; these may need 7260786Sps to be edited. The terminal libraries will be some subset of 7360786Sps -lncurses -lcurses -ltermcap -ltermlib 7460786Sps 7560786Sps If you wish, you may edit defines.h to remove some optional features. 7660786Sps If you choose not to include some features in your version, you may 7760786Sps wish to edit the manual page "less.nro" and the help page "less.hlp" 7860786Sps to remove the descriptions of the features which you are removing. 7960786Sps If you edit less.hlp, you should run "make -f Makefile.aut help.c". 8060786Sps 8160786Sps4. Type "make" and watch the fun. 8260786Sps 8360786Sps5. If the make succeeds, it will generate the programs "less", 8460786Sps "lesskey" and "lessecho" in your current directory. Test the 8560786Sps generated programs. 8660786Sps 8760786Sps6. When satisfied that it works, if you wish to install it 8860786Sps in a public place, type "make install". 8960786Sps 9060786Sps The default install destinations are: 9160786Sps Executables (less, lesskey, lessecho) in /usr/local/bin 9260786Sps Documentation (less.nro, lesskey.nro) in /usr/local/man/man1 9360786Sps If you want to install any of these files elsewhere, define 9460786Sps bindir and/or mandir to the appropriate directories. 9560786Sps 9660786SpsIf you have any problems building or running "less", suggestions, 9789019Spscomplaints, etc., you may mail to the author at markn@greenwoodsoftware.com. 9860786Sps 9960786SpsNote to hackers: comments noting possible improvements are enclosed 10060786Spsin double curly brackets {{ like this }}. 10160786Sps 10260786Sps 10360786Sps 10460786Sps======================================================================= 10560786SpsINSTALLATION (MS-DOS systems only, 10660786Sps with Microsoft C, Borland C, or DJGPP) 10760786Sps 10860786Sps1. Move the distributed source to its own directory. 10960786Sps Depending on your compiler, you may need to convert the source 11060786Sps to have CR-LF rather than LF as line terminators. 11160786Sps 11263128Sps2. If you are using Microsoft C, rename MAKEFILE.DSU to MAKEFILE. 11360786Sps If you are using Borland C, rename MAKEFILE.DSB to MAKEFILE. 11460786Sps If you are using DJGPP, rename MAKEFILE.DSG to MAKEFILE. 11560786Sps 11660786Sps3. Look at MAKEFILE to make sure that the definitions for CC and LIBDIR 11760786Sps are correct. CC should be the name of your C compiler and 11860786Sps LIBDIR should be the directory where the C libraries reside (for 11960786Sps Microsoft C only). If these definitions need to be changed, you can 12060786Sps either modify the definitions directly in MAKEFILE, or set your 12160786Sps environment variables CC and/or LIBDIR to override the definitions 12260786Sps in MAKEFILE. 12360786Sps 12460786Sps4. If you wish, you may edit DEFINES.DS to remove some optional features. 12560786Sps If you choose not to include some features in your version, you may 12660786Sps wish to edit the manual page LESS.MAN and the help page HELP.C 12760786Sps to remove the descriptions of the features which you are removing. 12860786Sps 12960786Sps5. Run your "make" program and watch the fun. 13060786Sps If your "make" requires a flag to import environment variables, 13160786Sps you should use that flag. 13260786Sps If your compiler runs out of memory, try running "make -n >cmds.bat" 13360786Sps and then run cmds.bat. 13460786Sps 13560786Sps6. If the make succeeds, it will generate the programs "LESS.EXE" and 13660786Sps "LESSKEY.EXE" in your current directory. Test the generated programs. 13760786Sps 13860786Sps7. When satisfied that it works, you may wish to install LESS.EXE and 13960786Sps LESSKEY.EXE in a directory which is included in your PATH. 14060786Sps 14160786Sps 14260786Sps 14360786Sps======================================================================= 14460786SpsINSTALLATION (Windows-95, Windows-98 and Windows-NT systems only, 14560786Sps with Borland C or Microsoft Visual C++) 14660786Sps 14760786Sps1. Move the distributed source to its own directory. 14860786Sps 14960786Sps2. If you are using Borland C, rename Makefile.wnb to Makefile. 15060786Sps If you are using Microsoft Visual C++, rename Makefile.wnm to Makefile. 15160786Sps 15260786Sps3. Check the Makefile to make sure the definitions look ok. 15360786Sps 15460786Sps4. If you wish, you may edit defines.wn to remove some optional features. 15560786Sps If you choose not to include some features in your version, you may 15660786Sps wish to edit the manual page less.man and the help page help.c 15760786Sps to remove the descriptions of the features which you are removing. 15860786Sps 15960786Sps5. Type "make" and watch the fun. 16060786Sps 16160786Sps6. If the make succeeds, it will generate the programs "less.exe" and 16260786Sps "lesskey.exe" in your current directory. Test the generated programs. 16360786Sps 16460786Sps7.

Move the distributed source to its own directory. 17660786Sps 17760786Sps2. Rename Makefile.o2e to Makefile. 17860786Sps 17960786Sps3. Check the Makefile to make sure the definitions look ok. 18060786Sps 18160786Sps4. If you wish, you may edit defines.o2 to remove some optional features. 18260786Sps If you choose not to include some features in your version, you may 18360786Sps wish to edit the manual page less.man and the help page help.c 18460786Sps to remove the descriptions of the features which you are removing. 18560786Sps 18660786Sps5. Type "make" and watch the fun. 18760786Sps 18860786Sps6. If the make succeeds, it will generate the programs "less.exe" and 18960786Sps "lesskey.exe" in your current directory. Test the generated programs. 19060786Sps 19160786Sps7. Make sure you have the emx runtime installed. You need the emx DLLs 19260786Sps emx.dll and emxlibcs.dll and also the termcap database, termcap.dat. 19360786Sps Make sure you have termcap.dat either in the default location or 19460786Sps somewhere in a directory listed in the PATH or INIT environment 19560786Sps variables. 19660786Sps 19789019Sps8. When satisfied that it works, you may wish to install less.exe, 19889019Sps lesskey.exe and scrsize.exe in a directory which is included in 19989019Sps your PATH. scrsize.exe is required only if you use a terminal 20089019Sps emulator such as xterm or rxvt. 20160786Sps 20260786Sps 20360786Sps 20460786Sps======================================================================= 20560786SpsINSTALLATION (OS-9 systems only, 20660786Sps with Microware C or Ultra C) 20760786Sps 20860786Sps1.

Type "dmake" and watch the fun. 22160786Sps The standard OS-9 "make" will probably not work.
