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". 4960786Sps --with-regex=lib 5060786Sps Specifies the regular expression library used by less for pattern 5160786Sps matching. The default is "auto", which means the configure program 5260786Sps finds a regular expression library automatically. Other values are: 5360786Sps posix Use the POSIX-compatible regcomp. 5460786Sps pcre Use the PCRE library. 5560786Sps regcmp Use the regcmp library. 5660786Sps re_comp Use the re_comp library. 5760786Sps regcomp Use the V8-compatible regcomp. 5860786Sps regcomp-local Use Henry Spencer's V8-compatible regcomp 5960786Sps (source is supplied with less). 60161475Sdelphij --with-secure 61161475Sdelphij Builds a "secure" version of less, with some features disabled 62161475Sdelphij to prevent users from viewing other files, accessing shell 63161475Sdelphij commands, etc. 6460786Sps 6560786Sps3. It is a good idea to look over the generated Makefile and defines.h 6660786Sps and make sure they look ok. If you know of any peculiarities of 6760786Sps your system that configure might not have detected, you may fix the 6860786Sps Makefile now. Take particular notice of the list of "terminal" 6960786Sps libraries in the LIBS definition in the Makefile; these may need 7060786Sps to be edited. The terminal libraries will be some subset of 7160786Sps -lncurses -lcurses -ltermcap -ltermlib 7260786Sps 7360786Sps If you wish, you may edit defines.h to remove some optional features. 7460786Sps If you choose not to include some features in your version, you may 7560786Sps wish to edit the manual page "less.nro" and the help page "less.hlp" 7660786Sps to remove the descriptions of the features which you are removing. 7760786Sps If you edit less.hlp, you should run "make -f Makefile.aut help.c". 7860786Sps 7960786Sps4. Type "make" and watch the fun. 8060786Sps 8160786Sps5. If the make succeeds, it will generate the programs "less", 8260786Sps "lesskey" and "lessecho" in your current directory. Test the 8360786Sps generated programs. 8460786Sps 8560786Sps6. When satisfied that it works, if you wish to install it 8660786Sps in a public place, type "make install". 8760786Sps 8860786Sps The default install destinations are: 8960786Sps Executables (less, lesskey, lessecho) in /usr/local/bin 9060786Sps Documentation (less.nro, lesskey.nro) in /usr/local/man/man1 9160786Sps If you want to install any of these files elsewhere, define 9260786Sps bindir and/or mandir to the appropriate directories. 9360786Sps 9460786SpsIf you have any problems building or running "less", suggestions, 9589019Spscomplaints, etc., you may mail to the author at markn@greenwoodsoftware.com. 9660786Sps 9760786SpsNote to hackers: comments noting possible improvements are enclosed 9860786Spsin double curly brackets {{ like this }}. 9960786Sps 10060786Sps 10160786Sps 10260786Sps======================================================================= 10360786SpsINSTALLATION (MS-DOS systems only, 10460786Sps with Microsoft C, Borland C, or DJGPP) 10560786Sps 10660786Sps1. Move the distributed source to its own directory. 10760786Sps Depending on your compiler, you may need to convert the source 10860786Sps to have CR-LF rather than LF as line terminators. 10960786Sps 11063128Sps2. If you are using Microsoft C, rename MAKEFILE.DSU to MAKEFILE. 11160786Sps If you are using Borland C, rename MAKEFILE.DSB to MAKEFILE. 11260786Sps If you are using DJGPP, rename MAKEFILE.DSG to MAKEFILE. 11360786Sps 11460786Sps3. Look at MAKEFILE to make sure that the definitions for CC and LIBDIR 11560786Sps are correct. CC should be the name of your C compiler and 11660786Sps LIBDIR should be the directory where the C libraries reside (for 11760786Sps Microsoft C only). If these definitions need to be changed, you can 11860786Sps either modify the definitions directly in MAKEFILE, or set your 11960786Sps environment variables CC and/or LIBDIR to override the definitions 12060786Sps in MAKEFILE. 12160786Sps 12260786Sps4. If you wish, you may edit DEFINES.DS to remove some optional features. 12360786Sps If you choose not to include some features in your version, you may 12460786Sps wish to edit the manual page LESS.MAN and the help page HELP.C 12560786Sps to remove the descriptions of the features which you are removing. 12660786Sps 12760786Sps5. Run your "make" program and watch the fun. 12860786Sps If your "make" requires a flag to import environment variables, 12960786Sps you should use that flag. 13060786Sps If your compiler runs out of memory, try running "make -n >cmds.bat" 13160786Sps and then run cmds.bat. 13260786Sps 13360786Sps6. If the make succeeds, it will generate the programs "LESS.EXE" and 13460786Sps "LESSKEY.EXE" in your current directory. Test the generated programs. 13560786Sps 13660786Sps7. When satisfied that it works, you may wish to install LESS.EXE and 13760786Sps LESSKEY.EXE in a directory which is included in your PATH. 13860786Sps 13960786Sps 14060786Sps 14160786Sps======================================================================= 14260786SpsINSTALLATION (Windows-95, Windows-98 and Windows-NT systems only, 14360786Sps with Borland C or Microsoft Visual C++) 14460786Sps 14560786Sps1. Move the distributed source to its own directory. 14660786Sps 14760786Sps2. If you are using Borland C, rename Makefile.wnb to Makefile. 14860786Sps If you are using Microsoft Visual C++, rename Makefile.wnm to Makefile. 14960786Sps 15060786Sps3. Check the Makefile to make sure the definitions look ok. 15160786Sps 15260786Sps4. If you wish, you may edit defines.wn to remove some optional features. 15360786Sps If you choose not to include some features in your version, you may 15460786Sps wish to edit the manual page less.man and the help page help.c 15560786Sps to remove the descriptions of the features which you are removing. 15660786Sps 15760786Sps5. Type "make" and watch the fun. 15860786Sps 15960786Sps6. If the make succeeds, it will generate the programs "less.exe" and 16060786Sps "lesskey.exe" in your current directory. Test the generated programs. 16160786Sps 16260786Sps7. When satisfied that it works, if you wish to install it 16360786Sps in a public place, type "make install". 16460786Sps See step 6 of the Unix installation instructions for details 16560786Sps on how to change the default installation directories. 16660786Sps 16760786Sps 16860786Sps 16960786Sps======================================================================= 17060786SpsINSTALLATION (OS/2 systems only, 17160786Sps with EMX C) 17260786Sps 17360786Sps1. Move the distributed source to its own directory. 17460786Sps 17560786Sps2. Rename Makefile.o2e to Makefile. 17660786Sps 17760786Sps3. Check the Makefile to make sure the definitions look ok. 17860786Sps 17960786Sps4. If you wish, you may edit defines.o2 to remove some optional features. 18060786Sps If you choose not to include some features in your version, you may 18160786Sps wish to edit the manual page less.man and the help page help.c 18260786Sps to remove the descriptions of the features which you are removing. 18360786Sps 18460786Sps5. Type "make" and watch the fun. 18560786Sps 18660786Sps6. If the make succeeds, it will generate the programs "less.exe" and 18760786Sps "lesskey.exe" in your current directory. Test the generated programs. 18860786Sps 18960786Sps7. Make sure you have the emx runtime installed. You need the emx DLLs 19060786Sps emx.dll and emxlibcs.dll and also the termcap database, termcap.dat. 19160786Sps Make sure you have termcap.dat either in the default location or 19260786Sps somewhere in a directory listed in the PATH or INIT environment 19360786Sps variables. 19460786Sps 19589019Sps8. When satisfied that it works, you may wish to install less.exe, 19689019Sps lesskey.exe and scrsize.exe in a directory which is included in 19789019Sps your PATH. scrsize.exe is required only if you use a terminal 19889019Sps emulator such as xterm or rxvt. 19960786Sps 20060786Sps 20160786Sps 20260786Sps======================================================================= 20360786SpsINSTALLATION (OS-9 systems only, 20460786Sps with Microware C or Ultra C) 20560786Sps 20660786Sps1.

Type "dmake" and watch the fun. 21960786Sps The standard OS-9 "make" will probably not work. If you don't 22060786Sps have dmake, you can get a copy from os9archive.rtsi.com. 22160786Sps 22260786Sps6.
