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). 6060786Sps 6160786Sps3. It is a good idea to look over the generated Makefile and defines.h 6260786Sps and make sure they look ok. If you know of any peculiarities of 6360786Sps your system that configure might not have detected, you may fix the 6460786Sps Makefile now. Take particular notice of the list of "terminal" 6560786Sps libraries in the LIBS definition in the Makefile; these may need 6660786Sps to be edited. The terminal libraries will be some subset of 6760786Sps -lncurses -lcurses -ltermcap -ltermlib 6860786Sps 6960786Sps If you wish, you may edit defines.h to remove some optional features. 7060786Sps If you wish to build a "secure" version of less (which disables all 7160786Sps features which might allow a user to do unintended things to the system 7260786Sps on which less is running), edit defines.h and define SECURE to 1. 7360786Sps If you choose not to include some features in your version, you may 7460786Sps wish to edit the manual page "less.nro" and the help page "less.hlp" 7560786Sps to remove the descriptions of the features which you are removing. 7660786Sps If you edit less.hlp, you should run "make -f Makefile.aut help.c". 7760786Sps 7860786Sps4. Type "make" and watch the fun. 7960786Sps 8060786Sps5. If the make succeeds, it will generate the programs "less", 8160786Sps "lesskey" and "lessecho" in your current directory. Test the 8260786Sps generated programs. 8360786Sps 8460786Sps6. When satisfied that it works, if you wish to install it 8560786Sps in a public place, type "make install". 8660786Sps 8760786Sps The default install destinations are: 8860786Sps Executables (less, lesskey, lessecho) in /usr/local/bin 8960786Sps Documentation (less.nro, lesskey.nro) in /usr/local/man/man1 9060786Sps If you want to install any of these files elsewhere, define 9160786Sps bindir and/or mandir to the appropriate directories. 9260786Sps 9360786SpsIf you have any problems building or running "less", suggestions, 9460786Spscomplaints, etc., you may mail to the author at marknu@flash.net. 9560786Sps 9660786SpsNote to hackers: comments noting possible improvements are enclosed 9760786Spsin double curly brackets {{ like this }}. 9860786Sps 9960786Sps 10060786Sps 10160786Sps======================================================================= 10260786SpsINSTALLATION (MS-DOS systems only, 10360786Sps with Microsoft C, Borland C, or DJGPP) 10460786Sps 10560786Sps1. Move the distributed source to its own directory. 10660786Sps Depending on your compiler, you may need to convert the source 10760786Sps to have CR-LF rather than LF as line terminators. 10860786Sps 10963128Sps2. If you are using Microsoft C, rename MAKEFILE.DSU to MAKEFILE. 11060786Sps If you are using Borland C, rename MAKEFILE.DSB to MAKEFILE. 11160786Sps If you are using DJGPP, rename MAKEFILE.DSG to MAKEFILE. 11260786Sps 11360786Sps3. Look at MAKEFILE to make sure that the definitions for CC and LIBDIR 11460786Sps are correct. CC should be the name of your C compiler and 11560786Sps LIBDIR should be the directory where the C libraries reside (for 11660786Sps Microsoft C only). If these definitions need to be changed, you can 11760786Sps either modify the definitions directly in MAKEFILE, or set your 11860786Sps environment variables CC and/or LIBDIR to override the definitions 11960786Sps in MAKEFILE. 12060786Sps 12160786Sps4. If you wish, you may edit DEFINES.DS to remove some optional features. 12260786Sps If you choose not to include some features in your version, you may 12360786Sps wish to edit the manual page LESS.MAN and the help page HELP.C 12460786Sps to remove the descriptions of the features which you are removing. 12560786Sps 12660786Sps5. Run your "make" program and watch the fun. 12760786Sps If your "make" requires a flag to import environment variables, 12860786Sps you should use that flag. 12960786Sps If your compiler runs out of memory, try running "make -n >cmds.bat" 13060786Sps and then run cmds.bat. 13160786Sps 13260786Sps6. If the make succeeds, it will generate the programs "LESS.EXE" and 13360786Sps "LESSKEY.EXE" in your current directory. Test the generated programs. 13460786Sps 13560786Sps7. When satisfied that it works, you may wish to install LESS.EXE and 13660786Sps LESSKEY.EXE in a directory which is included in your PATH. 13760786Sps 13860786Sps 13960786Sps 14060786Sps======================================================================= 14160786SpsINSTALLATION (Windows-95, Windows-98 and Windows-NT systems only, 14260786Sps with Borland C or Microsoft Visual C++) 14360786Sps 14460786Sps1. Move the distributed source to its own directory. 14560786Sps 14660786Sps2. If you are using Borland C, rename Makefile.wnb to Makefile. 14760786Sps If you are using Microsoft Visual C++, rename Makefile.wnm to Makefile. 14860786Sps 14960786Sps3. Check the Makefile to make sure the definitions look ok. 15060786Sps 15160786Sps4. If you wish, you may edit defines.wn to remove some optional features. 15260786Sps If you choose not to include some features in your version, you may 15360786Sps wish to edit the manual page less.man and the help page help.c 15460786Sps to remove the descriptions of the features which you are removing. 15560786Sps 15660786Sps5. Type "make" and watch the fun. 15760786Sps 15860786Sps6. If the make succeeds, it will generate the programs "less.exe" and 15960786Sps "lesskey.exe" in your current directory. Test the generated programs. 16060786Sps 16160786Sps7. When satisfied that it works, if you wish to install it 16260786Sps in a public place, type "make install". 16360786Sps See step 6 of the Unix installation instructions for details 16460786Sps on how to change the default installation directories. 16560786Sps 16660786Sps 16760786Sps 16860786Sps======================================================================= 16960786SpsINSTALLATION (OS/2 systems only, 17060786Sps with EMX C) 17160786Sps 17260786Sps1. Move the distributed source to its own directory. 17360786Sps 17460786Sps2. Rename Makefile.o2e to Makefile. 17560786Sps 17660786Sps3. Check the Makefile to make sure the definitions look ok. 17760786Sps 17860786Sps4. If you wish, you may edit defines.o2 to remove some optional features. 17960786Sps If you choose not to include some features in your version, you may 18060786Sps wish to edit the manual page less.man and the help page help.c 18160786Sps to remove the descriptions of the features which you are removing. 18260786Sps 18360786Sps5. Type "make" and watch the fun. 18460786Sps 18560786Sps6. If the make succeeds, it will generate the programs "less.exe" and 18660786Sps "lesskey.exe" in your current directory. Test the generated programs. 18760786Sps 18860786Sps7. Make sure you have the emx runtime installed. You need the emx DLLs 18960786Sps emx.dll and emxlibcs.dll and also the termcap database, termcap.dat. 19060786Sps Make sure you have termcap.dat either in the default location or 19160786Sps somewhere in a directory listed in the PATH or INIT environment 19260786Sps variables. 19360786Sps 19460786Sps8. When satisfied that it works, you may wish to install less.exe and 19560786Sps lesskey.exe in a directory which is included in your PATH. 19660786Sps 19760786Sps 19860786Sps 19960786Sps======================================================================= 20060786SpsINSTALLATION (OS-9 systems only, 20160786Sps with Microware C or Ultra C) 20260786Sps 20360786Sps1.

Type "dmake" and watch the fun. 21660786Sps The standard OS-9 "make" will probably not work. If you don't 21760786Sps have dmake, you can get a copy from os9archive.rtsi.com. 21860786Sps 21960786Sps6.
