1Basic Installation 2================== 3 4 These are generic installation instructions. 5 6 The `configure' shell script attempts to guess correct values for 7various system-dependent variables used during compilation. It uses 8those values to create a `Makefile' in each directory of the package. 9It may also create one or more `.h' files containing system-dependent 10definitions. Finally, it creates a shell script `config.status' that 11you can run in the future to recreate the current configuration, a file 12`config.cache' that saves the results of its tests to speed up 13reconfiguring, and a file `config.log' containing compiler output 14(useful mainly for debugging `configure'). 15 16 If you need to do unusual things to compile the package, please try 17to figure out how `configure' could check whether to do them, and mail 18diffs or instructions to the address given in the `README' so they can 19be considered for the next release. If at some point `config.cache' 20contains results you don't want to keep, you may remove or edit it. 21 22 The file `configure.in' is used to create `configure' by a program 23called `autoconf'. You only need `configure.in' if you want to change 24it or regenerate `configure' using a newer version of `autoconf'. 25 26The simplest way to compile this package is: 27 28 1. `cd' to the directory containing the package's source code and type 29 `./configure' to configure the package for your system. If you're 30 using `csh' on an old version of System V, you might need to type 31 `sh ./configure' instead to prevent `csh' from trying to execute 32 `configure' itself. 33 34 Running `configure' takes awhile. While running, it prints some 35 messages telling which features it is checking for. 36 37 2. Type `make' to compile the package. 38 39 3. Optionally, type `make check' to run any self-tests that come with 40 the package. 41 42 4. Type `make install' to install the programs and any data files and 43 documentation. 44 45 5. You can remove the program binaries and object files from the 46 source code directory by typing `make clean'. To also remove the 47 files that `configure' created (so you can compile the package for 48 a different kind of computer), type `make distclean'. There is 49 also a `make maintainer-clean' target, but that is intended mainly 50 for the package's developers. If you use it, you may have to get 51 all sorts of other programs in order to regenerate files that came 52 with the distribution. 53
