Move the distributed source to its own directory and unpack it, 4060786Sps if you have not already done so. 4160786Sps 4260786Sps2. Type "sh configure". 4360786Sps This will generate a Makefile and a defines.h. 4460786Sps Warning: if you have a GNU sed, make sure it is version 2.05 or later. 4560786Sps 4660786Sps The file INSTALL describes the usage of the configure program in 4760786Sps general. In addition, these options to configure are supported: 4860786Sps 4960786Sps --with-editor=program 5060786Sps Specifies the default editor program used by the "v" command. 5160786Sps The default is "vi". 52170256Sdelphij 5360786Sps --with-regex=lib 5460786Sps Specifies the regular expression library used by less for pattern 5560786Sps matching. The default is "auto", which means the configure program 5660786Sps finds a regular expression library automatically. Other values are: 57294286Sdelphij gnu Use the GNU regex library. 58294286Sdelphij pcre Use the PCRE library. 5960786Sps posix Use the POSIX-compatible regcomp. 6060786Sps regcmp Use the regcmp library. 6160786Sps re_comp Use the re_comp library. 6260786Sps regcomp Use the V8-compatible regcomp. 6360786Sps regcomp-local Use Henry Spencer's V8-compatible regcomp 6460786Sps (source is supplied with less). 65237613Sdelphij none No regular expressions, only simple string matching. 66161475Sdelphij --with-secure 67161475Sdelphij Builds a "secure" version of less, with some features disabled 68237613Sdelphij to prevent users from viewing other files, accessing shell 69237613Sdelphij commands, etc. 7060786Sps 71170256Sdelphij 7260786Sps3. It is a good idea to look over the generated Makefile and defines.h 7360786Sps and make sure they look ok. If you know of any peculiarities of 7460786Sps your system that configure might not have detected, you may fix the 7560786Sps Makefile now. Take particular notice of the list of "terminal" 7660786Sps libraries in the LIBS definition in the Makefile; these may need 7760786Sps to be edited. The terminal libraries will be some subset of 7860786Sps -lncurses -lcurses -ltermcap -ltermlib 7960786Sps 8060786Sps If you wish, you may edit defines.h to remove some optional features. 8160786Sps If you choose not to include some features in your version, you may 8260786Sps wish to edit the manual page "less.nro" and the help page "less.hlp" 8360786Sps to remove the descriptions of the features which you are removing. 8460786Sps If you edit less.hlp, you should run "make -f Makefile.aut help.c". 8560786Sps 8660786Sps4. Type "make" and watch the fun. 8760786Sps 8860786Sps5. If the make succeeds, it will generate the programs "less", 8960786Sps "lesskey" and "lessecho" in your current directory. Test the 9060786Sps generated programs. 9160786Sps 9260786Sps6. When satisfied that it works, if you wish to install it 9360786Sps in a public place, type "make install". 9460786Sps 9560786Sps The default install destinations are: 9660786Sps Executables (less, lesskey, lessecho) in /usr/local/bin 9760786Sps Documentation (less.nro, lesskey.nro) in /usr/local/man/man1 9860786Sps If you want to install any of these files elsewhere, define 9960786Sps bindir and/or mandir to the appropriate directories. 10060786Sps 10160786SpsIf you have any problems building or running "less", suggestions, 102237613Sdelphijcomplaints, etc., you may mail to bug-less@gnu.org. 10360786Sps 10460786SpsNote to hackers: comments noting possible improvements are enclosed 10560786Spsin double curly brackets {{ like this }}. 10660786Sps 107221715Sdelphij(Note that the above note was originally written at a time when 108221715Sdelphij"hackers" most commonly meant "enthusiastic and dedicated computer 109221715Sdelphijprogrammers", not "persons who attempt to circumvent computer security".) 11060786Sps 11160786Sps 112221715Sdelphij 11360786Sps======================================================================= 11460786SpsINSTALLATION (MS-DOS systems only, 11560786Sps with Microsoft C, Borland C, or DJGPP) 11660786Sps 11760786Sps1. Move the distributed source to its own directory. 11860786Sps Depending on your compiler, you may need to convert the source 11960786Sps to have CR-LF rather than LF as line terminators. 12060786Sps 12163128Sps2. If you are using Microsoft C, rename MAKEFILE.DSU to MAKEFILE. 12260786Sps If you are using Borland C, rename MAKEFILE.DSB to MAKEFILE. 12360786Sps If you are using DJGPP, rename MAKEFILE.DSG to MAKEFILE. 12460786Sps 12560786Sps3. Look at MAKEFILE to make sure that the definitions for CC and LIBDIR 12660786Sps are correct. CC should be the name of your C compiler and 12760786Sps LIBDIR should be the directory where the C libraries reside (for 12860786Sps Microsoft C only). If these definitions need to be changed, you can 12960786Sps either modify the definitions directly in MAKEFILE, or set your 13060786Sps environment variables CC and/or LIBDIR to override the definitions 13160786Sps in MAKEFILE. 13260786Sps 13360786Sps4. If you wish, you may edit DEFINES.DS to remove some optional features. 13460786Sps If you choose not to include some features in your version, you may 13560786Sps wish to edit the manual page LESS.MAN and the help page HELP.C 13660786Sps to remove the descriptions of the features which you are removing. 13760786Sps 13860786Sps5. Run your "make" program and watch the fun. 13960786Sps If your "make" requires a flag to import environment variables, 14060786Sps you should use that flag. 14160786Sps If your compiler runs out of memory, try running "make -n >cmds.bat" 14260786Sps and then run cmds.bat. 14360786Sps 14460786Sps6. If the make succeeds, it will generate the programs "LESS.EXE" and 14560786Sps "LESSKEY.EXE" in your current directory. Test the generated programs. 14660786Sps 14760786Sps7. When satisfied that it works, you may wish to install LESS.EXE and 14860786Sps LESSKEY.EXE in a directory which is included in your PATH. 14960786Sps 15060786Sps 15160786Sps 15260786Sps======================================================================= 15360786SpsINSTALLATION (Windows-95, Windows-98 and Windows-NT systems only, 15460786Sps with Borland C or Microsoft Visual C++) 15560786Sps 15660786Sps1.
