Move the distributed source to its own directory and unpack it, 3960786Sps if you have not already done so. 4060786Sps 4160786Sps2. Type "sh configure". 4260786Sps This will generate a Makefile and a defines.h. 4360786Sps Warning: if you have a GNU sed, make sure it is version 2.05 or later. 4460786Sps 4560786Sps The file INSTALL describes the usage of the configure program in 4660786Sps general. In addition, these options to configure are supported: 4760786Sps 4860786Sps --with-editor=program 4960786Sps Specifies the default editor program used by the "v" command. 5060786Sps The default is "vi". 51170256Sdelphij 5260786Sps --with-regex=lib 5360786Sps Specifies the regular expression library used by less for pattern 5460786Sps matching. The default is "auto", which means the configure program 5560786Sps finds a regular expression library automatically. Other values are: 5660786Sps posix Use the POSIX-compatible regcomp. 5760786Sps pcre Use the PCRE library. 5860786Sps regcmp Use the regcmp library. 5960786Sps re_comp Use the re_comp library. 6060786Sps regcomp Use the V8-compatible regcomp. 6160786Sps regcomp-local Use Henry Spencer's V8-compatible regcomp 6260786Sps (source is supplied with less). 63237613Sdelphij none No regular expressions, only simple string matching. 64161475Sdelphij --with-secure 65161475Sdelphij Builds a "secure" version of less, with some features disabled 66237613Sdelphij to prevent users from viewing other files, accessing shell 67237613Sdelphij commands, etc. 6860786Sps 69170256Sdelphij 7060786Sps3. It is a good idea to look over the generated Makefile and defines.h 7160786Sps and make sure they look ok. If you know of any peculiarities of 7260786Sps your system that configure might not have detected, you may fix the 7360786Sps Makefile now. Take particular notice of the list of "terminal" 7460786Sps libraries in the LIBS definition in the Makefile; these may need 7560786Sps to be edited. The terminal libraries will be some subset of 7660786Sps -lncurses -lcurses -ltermcap -ltermlib 7760786Sps 7860786Sps If you wish, you may edit defines.h to remove some optional features. 7960786Sps If you choose not to include some features in your version, you may 8060786Sps wish to edit the manual page "less.nro" and the help page "less.hlp" 8160786Sps to remove the descriptions of the features which you are removing. 8260786Sps If you edit less.hlp, you should run "make -f Makefile.aut help.c". 8360786Sps 8460786Sps4. Type "make" and watch the fun. 8560786Sps 8660786Sps5. If the make succeeds, it will generate the programs "less", 8760786Sps "lesskey" and "lessecho" in your current directory. Test the 8860786Sps generated programs. 8960786Sps 9060786Sps6. When satisfied that it works, if you wish to install it 9160786Sps in a public place, type "make install". 9260786Sps 9360786Sps The default install destinations are: 9460786Sps Executables (less, lesskey, lessecho) in /usr/local/bin 9560786Sps Documentation (less.nro, lesskey.nro) in /usr/local/man/man1 9660786Sps If you want to install any of these files elsewhere, define 9760786Sps bindir and/or mandir to the appropriate directories. 9860786Sps 9960786SpsIf you have any problems building or running "less", suggestions, 100237613Sdelphijcomplaints, etc., you may mail to bug-less@gnu.org. 10160786Sps 10260786SpsNote to hackers: comments noting possible improvements are enclosed 10360786Spsin double curly brackets {{ like this }}. 10460786Sps 105221715Sdelphij(Note that the above note was originally written at a time when 106221715Sdelphij"hackers" most commonly meant "enthusiastic and dedicated computer 107221715Sdelphijprogrammers", not "persons who attempt to circumvent computer security".) 10860786Sps 10960786Sps 110221715Sdelphij 11160786Sps======================================================================= 11260786SpsINSTALLATION (MS-DOS systems only, 11360786Sps with Microsoft C, Borland C, or DJGPP) 11460786Sps 11560786Sps1. Move the distributed source to its own directory. 11660786Sps Depending on your compiler, you may need to convert the source 11760786Sps to have CR-LF rather than LF as line terminators. 11860786Sps 11963128Sps2. If you are using Microsoft C, rename MAKEFILE.DSU to MAKEFILE. 12060786Sps If you are using Borland C, rename MAKEFILE.DSB to MAKEFILE. 12160786Sps If you are using DJGPP, rename MAKEFILE.DSG to MAKEFILE. 12260786Sps 12360786Sps3. Look at MAKEFILE to make sure that the definitions for CC and LIBDIR 12460786Sps are correct. CC should be the name of your C compiler and 12560786Sps LIBDIR should be the directory where the C libraries reside (for 12660786Sps Microsoft C only). If these definitions need to be changed, you can 12760786Sps either modify the definitions directly in MAKEFILE, or set your 12860786Sps environment variables CC and/or LIBDIR to override the definitions 12960786Sps in MAKEFILE. 13060786Sps 13160786Sps4. If you wish, you may edit DEFINES.DS to remove some optional features. 13260786Sps If you choose not to include some features in your version, you may 13360786Sps wish to edit the manual page LESS.MAN and the help page HELP.C 13460786Sps to remove the descriptions of the features which you are removing. 13560786Sps 13660786Sps5. Run your "make" program and watch the fun. 13760786Sps If your "make" requires a flag to import environment variables, 13860786Sps you should use that flag. 13960786Sps If your compiler runs out of memory, try running "make -n >cmds.bat" 14060786Sps and then run cmds.bat. 14160786Sps 14260786Sps6. If the make succeeds, it will generate the programs "LESS.EXE" and 14360786Sps "LESSKEY.EXE" in your current directory. Test the generated programs. 14460786Sps 14560786Sps7. When satisfied that it works, you may wish to install LESS.EXE and 14660786Sps LESSKEY.EXE in a directory which is included in your PATH. 14760786Sps 14860786Sps 14960786Sps 15060786Sps======================================================================= 15160786SpsINSTALLATION (Windows-95, Windows-98 and Windows-NT systems only, 15260786Sps with Borland C or Microsoft Visual C++) 15360786Sps 15460786Sps1.
