1NOTE: 2->*nix Systems: use the configure script and everything should work without problems. 3->MSW: FIRST you need the mingw compiler (i think cygwin must work too, but you will have to modify the configure.in and change MINGW32 for CYGWIN) 4Then, run configure and pray. If it finds everything it needs (the only thing missed may be the pthreads library) is ready to compile. 5 6 7Basic Installation 8================== 9 10 These are generic installation instructions. 11 12 The `configure' shell script attempts to guess correct values for 13various system-dependent variables used during compilation. It uses 14those values to create a `Makefile' in each directory of the package. 15It may also create one or more `.h' files containing system-dependent 16definitions. Finally, it creates a shell script `config.status' that 17you can run in the future to recreate the current configuration, a file 18`config.cache' that saves the results of its tests to speed up 19reconfiguring, and a file `config.log' containing compiler output 20(useful mainly for debugging `configure'). 21 22 If you need to do unusual things to compile the package, please try 23to figure out how `configure' could check whether to do them, and mail 24diffs or instructions to the address given in the `README' so they can 25be considered for the next release. If at some point `config.cache' 26contains results you don't want to keep, you may remove or edit it. 27 28 The file `configure.in' is used to create `configure' by a program 29called `autoconf'. You only need `configure.in' if you want to change 30it or regenerate `configure' using a newer version of `autoconf'. 31 32The simplest way to compile this package is: 33 34 1. `cd' to the directory containing the package's source code and type 35 `./configure' to configure the package for your system. If you're 36 using `csh' on an old version of System V, you might need to type 37 `sh ./configure' instead to prevent `csh' from trying to execute 38 `configure' itself. 39 40 Running `configure' takes awhile. While running, it prints some 41 messages telling which features it is checking for. 42 43 2. Type `make' to compile the package. 44 45 3. Optionally, type `make check' to run any self-tests that come with 46 the package. 47 48 4. Type `make install' to install the programs and any data files and 49 documentation. 50 51 5. You can remove the program binaries and object files from the 52 source code directory by typing `make clean'. To also remove the 53 files that `configure' created (so you can compile the package for 54 a different kind of computer), type `make distclean'. There is 55 also a `make maintainer-clean' target, but that is intended mainly 56 for the package's developers. If you use it, you may have to get 57 all sorts of other programs in order to regenerate files that came 58 with the distribution. 59 60Compilers and Options 61===================== 62 63 Some systems require unusual options for compilation or linking that 64the `configure' script does not know about. You can give `configure' 65initial values for variables by setting them in the environment. Using 66a Bourne-compatible shell, you can do that on the command line like 67this: 68 CC=c89 CFLAGS=-O2 LIBS=-lposix ./configure 69 70Or on systems that have the `env' program, you can do it like this: 71 env CPPFLAGS=-I/usr/local/include LDFLAGS=-s ./configure 72 73Compiling For Multiple Architectures 74==================================== 75 76 You can compile the package for more than one kind of computer at the 77same time, by placing the object files for each architecture in their 78own directory. To do this, you must use a version of `make' that 79supports the `VPATH' variable, such as GNU `make'. `cd' to the 80directory where you want the object files and executables to go and run 81the `configure' script. `configure' automatically checks for the 82source code in the directory that `configure' is in and in `..'. 83 84 If you have to use a `make' that does not supports the `VPATH' 85variable, you have to compile the package for one architecture at a time 86in the source code directory. After you have installed the package for 87one architecture, use `make distclean' before reconfiguring for another 88architecture. 89 90Installation Names 91================== 92 93 By default, `make install' will install the package's files in 94`/usr/local/bin', `/usr/local/man', etc. You can specify an 95installation prefix other than `/usr/local' by giving `configure' the 96option `--prefix=PATH'. 97 98 You can specify separate installation prefixes for 99architecture-specific files and architecture-independent files. If you 100give `configure' the option `--exec-prefix=PATH', the package will use 101PATH as the prefix for installing programs and libraries. 102Documentation and other data files will still use the regular prefix. 103 104 In addition, if you use an unusual directory layout you can give 105options like `--bindir=PATH' to specify different values for particular 106kinds of files. Run `configure --help' for a list of the directories 107you can set and what kinds of files go in them. 108 109 If the package supports it, you can cause programs to be installed 110with an extra prefix or suffix on their names by giving `configure' the 111option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'. 112 113Optional Features 114================= 115 116 Some packages pay attention to `--enable-FEATURE' options to 117`configure', where FEATURE indicates an optional part of the package. 118They may also pay attention to `--with-PACKAGE' options, where PACKAGE 119is something like `gnu-as' or `x' (for the X Window System). The 120`README' should mention any `--enable-' and `--with-' options that the 121package recognizes. 122 123 For packages that use the X Window System, `configure' can usually 124find the X include and library files automatically, but if it doesn't, 125you can use the `configure' options `--x-includes=DIR' and 126`--x-libraries=DIR' to specify their locations. 127 128Specifying the System Type 129========================== 130 131 There may be some features `configure' can not figure out 132automatically, but needs to determine by the type of host the package 133will run on. Usually `configure' can figure that out, but if it prints 134a message saying it can not guess the host type, give it the 135`--host=TYPE' option. TYPE can either be a short name for the system 136type, such as `sun4', or a canonical name with three fields: 137 CPU-COMPANY-SYSTEM 138 139See the file `config.sub' for the possible values of each field. If 140`config.sub' isn't included in this package, then this package doesn't 141need to know the host type. 142 143 If you are building compiler tools for cross-compiling, you can also 144use the `--target=TYPE' option to select the type of system they will 145produce code for and the `--build=TYPE' option to select the type of 146system on which you are compiling the package. 147 148Sharing Defaults 149================ 150 151 If you want to set default values for `configure' scripts to share, 152you can create a site shell script called `config.site' that gives 153default values for variables like `CC', `cache_file', and `prefix'. 154`configure' looks for `PREFIX/share/config.site' if it exists, then 155`PREFIX/etc/config.site' if it exists. Or, you can set the 156`CONFIG_SITE' environment variable to the location of the site script. 157A warning: not all `configure' scripts look for a site script. 158 159Operation Controls 160================== 161 162 `configure' recognizes the following options to control how it 163operates. 164 165`--cache-file=FILE' 166 Use and save the results of the tests in FILE instead of 167 `./config.cache'. Set FILE to `/dev/null' to disable caching, for 168 debugging `configure'. 169 170`--help' 171 Print a summary of the options to `configure', and exit. 172 173`--quiet' 174`--silent' 175`-q' 176 Do not print messages saying which checks are being made. To 177 suppress all normal output, redirect it to `/dev/null' (any error 178 messages will still be shown). 179 180`--srcdir=DIR' 181 Look for the package's source code in directory DIR. Usually 182 `configure' can determine that directory automatically. 183 184`--version' 185 Print the version of Autoconf used to generate the `configure' 186 script, and exit. 187 188`configure' also accepts some other, not widely useful, options. 189
