Move the distributed source to its own directory and unpack it, 3933965Sjdp if you have not already done so. 4033965Sjdp 4133965Sjdp2. Type "sh configure". 4233965Sjdp This will generate a Makefile and a defines.h. 4333965Sjdp Warning: if you have a GNU sed, make sure it is version 2.05 or later. 4433965Sjdp 4533965Sjdp The file INSTALL describes the usage of the configure program in 4633965Sjdp general. In addition, these options to configure are supported: 4733965Sjdp 48218822Sdim --with-editor=program 4933965Sjdp Specifies the default editor program used by the "v" command. 5033965Sjdp The default is "vi". 5133965Sjdp 5233965Sjdp --with-regex=lib 5333965Sjdp Specifies the regular expression library used by less for pattern 5433965Sjdp matching. The default is "auto", which means the configure program 5533965Sjdp finds a regular expression library automatically. Other values are: 5633965Sjdp posix Use the POSIX-compatible regcomp. 5733965Sjdp pcre Use the PCRE library. 5833965Sjdp regcmp Use the regcmp library. 5933965Sjdp re_comp Use the re_comp library. 6089857Sobrien regcomp Use the V8-compatible regcomp. 6189857Sobrien regcomp-local Use Henry Spencer's V8-compatible regcomp 6289857Sobrien (source is supplied with less). 6389857Sobrien --with-secure 6433965Sjdp Builds a "secure" version of less, with some features disabled 6533965Sjdp to prevent users from viewing other files, accessing shell 6633965Sjdp commands, etc. 67218822Sdim 6833965Sjdp 6933965Sjdp3. It is a good idea to look over the generated Makefile and defines.h 7033965Sjdp and make sure they look ok. If you know of any peculiarities of 7133965Sjdp your system that configure might not have detected, you may fix the 72218822Sdim Makefile now. Take particular notice of the list of "terminal" 7333965Sjdp libraries in the LIBS definition in the Makefile; these may need 7433965Sjdp to be edited. The terminal libraries will be some subset of 7533965Sjdp -lncurses -lcurses -ltermcap -ltermlib 7633965Sjdp 7733965Sjdp If you wish, you may edit defines.h to remove some optional features. 7833965Sjdp If you choose not to include some features in your version, you may 7933965Sjdp wish to edit the manual page "less.nro" and the help page "less.hlp" 8033965Sjdp to remove the descriptions of the features which you are removing. 8133965Sjdp If you edit less.hlp, you should run "make -f Makefile.aut help.c". 8233965Sjdp 8333965Sjdp4. Type "make" and watch the fun. 8433965Sjdp 8533965Sjdp5. If the make succeeds, it will generate the programs "less", 8633965Sjdp "lesskey" and "lessecho" in your current directory. Test the 8733965Sjdp generated programs. 8833965Sjdp 8933965Sjdp6. When satisfied that it works, if you wish to install it 9033965Sjdp in a public place, type "make install". 9133965Sjdp 9233965Sjdp The default install destinations are: 9333965Sjdp Executables (less, lesskey, lessecho) in /usr/local/bin 9433965Sjdp Documentation (less.nro, lesskey.nro) in /usr/local/man/man1 9533965Sjdp If you want to install any of these files elsewhere, define 9633965Sjdp bindir and/or mandir to the appropriate directories. 97218822Sdim 9833965SjdpIf you have any problems building or running "less", suggestions, 9933965Sjdpcomplaints, etc., you may mail to the author at markn@greenwoodsoftware.com. 10033965Sjdp 10133965SjdpNote to hackers: comments noting possible improvements are enclosed 10233965Sjdpin double curly brackets {{ like this }}. 10333965Sjdp 10433965Sjdp(Note that the above note was originally written at a time when 10533965Sjdp"hackers" most commonly meant "enthusiastic and dedicated computer 10633965Sjdpprogrammers", not "persons who attempt to circumvent computer security".) 10733965Sjdp 108218822Sdim 10933965Sjdp 11033965Sjdp======================================================================= 11133965SjdpINSTALLATION (MS-DOS systems only, 11233965Sjdp with Microsoft C, Borland C, or DJGPP) 113218822Sdim 11433965Sjdp1. Move the distributed source to its own directory. 11533965Sjdp Depending on your compiler, you may need to convert the source 116 to have CR-LF rather than LF as line terminators. 117 1182. If you are using Microsoft C, rename MAKEFILE.DSU to MAKEFILE. 119 If you are using Borland C, rename MAKEFILE.DSB to MAKEFILE. 120 If you are using DJGPP, rename MAKEFILE.DSG to MAKEFILE. 121 1223. Look at MAKEFILE to make sure that the definitions for CC and LIBDIR 123 are correct. CC should be the name of your C compiler and 124 LIBDIR should be the directory where the C libraries reside (for 125 Microsoft C only). If these definitions need to be changed, you can 126 either modify the definitions directly in MAKEFILE, or set your 127 environment variables CC and/or LIBDIR to override the definitions 128 in MAKEFILE. 129 1304. If you wish, you may edit DEFINES.DS to remove some optional features. 131 If you choose not to include some features in your version, you may 132 wish to edit the manual page LESS.MAN and the help page HELP.C 133 to remove the descriptions of the features which you are removing. 134 1355. Run your "make" program and watch the fun. 136 If your "make" requires a flag to import environment variables, 137 you should use that flag. 138 If your compiler runs out of memory, try running "make -n >cmds.bat" 139 and then run cmds.bat. 140 1416. If the make succeeds, it will generate the programs "LESS.EXE" and 142 "LESSKEY.EXE" in your current directory. Test the generated programs. 143 1447. When satisfied that it works, you may wish to install LESS.EXE and 145 LESSKEY.EXE in a directory which is included in your PATH. 146 147 148 149======================================================================= 150INSTALLATION (Windows-95, Windows-98 and Windows-NT systems only, 151 with Borland C or Microsoft Visual C++) 152 1531. Move the distributed source to its own directory. 154 1552. If you are using Borland C, rename Makefile.wnb to Makefile. 156 If you are using Microsoft Visual C++, rename Makefile.wnm to Makefile. 157 1583. Check the Makefile to make sure the definitions look ok. 159 1604. If you wish, you may edit defines.wn to remove some optional features. 161 If you choose not to include some features in your version, you may 162 wish to edit the manual page less.man and the help page help.c 163 to remove the descriptions of the features which you are removing. 164 1655. Type "make" and watch the fun. 166 1676. If the make succeeds, it will generate the programs "less.exe" and 168 "lesskey.exe" in your current directory. Test the generated programs. 169 1707. When satisfied that it works, if you wish to install it 171 in a public place, type "make install". 172 See step 6 of the Unix installation instructions for details 173 on how to change the default installation directories. 174 175 176 177======================================================================= 178INSTALLATION (OS/2 systems only, 179 with EMX C) 180 1811. Move the distributed source to its own directory. 182 1832. Rename Makefile.o2e to Makefile. 184 1853. Check the Makefile to make sure the definitions look ok. 186 1874. If you wish, you may edit defines.o2 to remove some optional features. 188 If you choose not to include some features in your version, you may 189 wish to edit the manual page less.man and the help page help.c 190 to remove the descriptions of the features which you are removing. 191 1925. Type "make" and watch the fun. 193 1946. If the make succeeds, it will generate the programs "less.exe" and 195 "lesskey.exe" in your current directory. Test the generated programs. 196 1977. Make sure you have the emx runtime installed. You need the emx DLLs 198 emx.dll and emxlibcs.dll and also the termcap database, termcap.dat. 199 Make sure you have termcap.dat either in the default location or 200 somewhere in a directory listed in the PATH or INIT environment 201 variables. 202 2038. When satisfied that it works, you may wish to install less.exe, 204 lesskey.exe and scrsize.exe in a directory which is included in 205 your PATH. scrsize.exe is required only if you use a terminal 206 emulator such as xterm or rxvt. 207 208 209 210======================================================================= 211INSTALLATION (OS-9 systems only, 212 with Microware C or Ultra C) 213 2141. Move the distributed source to its own directory. 215 2162. If you are using Microware C, rename Makefile.o9c to Makefile. 217 If you are using Ultra C, rename Makefile.o9u to Makefile. 218 2193. Check the Makefile to make sure the definitions look ok. 220 2214. If you wish, you may edit defines.o9 to remove some optional features. 222 If you choose not to include some features in your version, you may 223 wish to edit the manual page less.man and the help page help.c 224 to remove the descriptions of the features which you are removing. 225 2265. Type "dmake" and watch the fun. 227 The standard OS-9 "make" will probably not work. If you don't 228 have dmake, you can get a copy from os9archive.rtsi.com. 229 2306. If the make succeeds, it will generate the programs "less" and 231 "lesskey" in your current directory. Test the generated programs. 232 2337. When satisfied that it works, if you wish to install it 234 in a public place, type "dmake install". 235 See step 6 of the Unix installation instructions for details 236 on how to change the default installation directories. 237 238======================================================================= 239ACKNOWLEDGMENTS: 240 Some versions of the less distribution are packaged using 241 Info-ZIP's compression utility. 242 Info-ZIP's software is free and can be obtained as source 243 code or executables from various anonymous-ftp sites, 244 including ftp.uu.net:/pub/archiving/zip. 245
