+Basic Installation |
+================== |
+ |
+ These are generic installation instructions. |
+ |
+ The `configure' shell script attempts to guess correct values for |
+various system-dependent variables used during compilation. It uses |
+those values to create a `Makefile' in each directory of the package. |
+It may also create one or more `.h' files containing system-dependent |
+definitions. Finally, it creates a shell script `config.status' that |
+you can run in the future to recreate the current configuration, a file |
+`config.cache' that saves the results of its tests to speed up |
+reconfiguring, and a file `config.log' containing compiler output |
+(useful mainly for debugging `configure'). |
+ |
+ If you need to do unusual things to compile the package, please try |
+to figure out how `configure' could check whether to do them, and mail |
+diffs or instructions to the address given in the `README' so they can |
+be considered for the next release. If at some point `config.cache' |
+contains results you don't want to keep, you may remove or edit it. |
+ |
+ The file `configure.in' is used to create `configure' by a program |
+called `autoconf'. You only need `configure.in' if you want to change |
+it or regenerate `configure' using a newer version of `autoconf'. |
+ |
+The simplest way to compile this package is: |
+ |
+ 1. `cd' to the directory containing the package's source code and type |
+ `./configure' to configure the package for your system. If you're |
+ using `csh' on an old version of System V, you might need to type |
+ `sh ./configure' instead to prevent `csh' from trying to execute |
+ `configure' itself. |
+ |
+ Running `configure' takes a while. While running, it prints some |
+ messages telling which features it is checking for. |
+ |
+ 2. Type `make' to compile the package. |
+ |
+ 3. Optionally, type `make check' to run any self-tests that come with |
+ the package. |
+ |
+ 4. Type `make install' to install the programs and any data files and |
+ documentation. |
+ |
+ 5. You can remove the program binaries and object files from the |
+ source code directory by typing `make clean'. To also remove the |
+ files that `configure' created (so you can compile the package for |
+ a different kind of computer), type `make distclean'. There is |
+ also a `make maintainer-clean' target, but that is intended mainly |
+ for the package's developers. If you use it, you may have to get |
+ all sorts of other programs in order to regenerate files that came |
+ with the distribution. |
+ |
+Compilers and Options |
+===================== |
+ |
+ Some systems require unusual options for compilation or linking that |
+the `configure' script does not know about. You can give `configure' |
+initial values for variables by setting them in the environment. Using |
+a Bourne-compatible shell, you can do that on the command line like |
+this: |
+ CC=c89 CFLAGS=-O2 LIBS=-lposix ./configure |
+ |
+Or on systems that have the `env' program, you can do it like this: |
+ env CPPFLAGS=-I/usr/local/include LDFLAGS=-s ./configure |
+ |
+Compiling For Multiple Architectures |
+==================================== |
+ |
+ You can compile the package for more than one kind of computer at the |
+same time, by placing the object files for each architecture in their |
+own directory. To do this, you must use a version of `make' that |
+supports the `VPATH' variable, such as GNU `make'. `cd' to the |
+directory where you want the object files and executables to go and run |
+the `configure' script. `configure' automatically checks for the |
+source code in the directory that `configure' is in and in `..'. |
+ |
+ If you have to use a `make' that does not supports the `VPATH' |
+variable, you have to compile the package for one architecture at a time |
+in the source code directory. After you have installed the package for |
+one architecture, use `make distclean' before reconfiguring for another |
+architecture. |
+ |
+Installation Names |
+================== |
+ |
+ By default, `make install' will install the package's files in |
+`/usr/local/bin', `/usr/local/man', etc. You can specify an |
+installation prefix other than `/usr/local' by giving `configure' the |
+option `--prefix=PATH'. |
+ |
+ You can specify separate installation prefixes for |
+architecture-specific files and architecture-independent files. If you |
+give `configure' the option `--exec-prefix=PATH', the package will use |
+PATH as the prefix for installing programs and libraries. |
+Documentation and other data files will still use the regular prefix. |
+ |
+ In addition, if you use an unusual directory layout you can give |
+options like `--bindir=PATH' to specify different values for particular |
+kinds of files. Run `configure --help' for a list of the directories |
+you can set and what kinds of files go in them. |
+ |
+ If the package supports it, you can cause programs to be installed |
+with an extra prefix or suffix on their names by giving `configure' the |
+option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'. |
+ |
+Optional Features |
+================= |
+ |
+ Some packages pay attention to `--enable-FEATURE' options to |
+`configure', where FEATURE indicates an optional part of the package. |
+They may also pay attention to `--with-PACKAGE' options, where PACKAGE |
+is something like `gnu-as' or `x' (for the X Window System). The |
+`README' should mention any `--enable-' and `--with-' options that the |
+package recognizes. |
+ |
+ For packages that use the X Window System, `configure' can usually |
+find the X include and library files automatically, but if it doesn't, |
+you can use the `configure' options `--x-includes=DIR' and |
+`--x-libraries=DIR' to specify their locations. |
+ |
+Specifying the System Type |
+========================== |
+ |
+ There may be some features `configure' can not figure out |
+automatically, but needs to determine by the type of host the package |
+will run on. Usually `configure' can figure that out, but if it prints |
+a message saying it can not guess the host type, give it the |
+`--host=TYPE' option. TYPE can either be a short name for the system |
+type, such as `sun4', or a canonical name with three fields: |
+ CPU-COMPANY-SYSTEM |
+ |
+See the file `config.sub' for the possible values of each field. If |
+`config.sub' isn't included in this package, then this package doesn't |
+need to know the host type. |
+ |
+ If you are building compiler tools for cross-compiling, you can also |
+use the `--target=TYPE' option to select the type of system they will |
+produce code for and the `--build=TYPE' option to select the type of |
+system on which you are compiling the package. |
+ |
+Sharing Defaults |
+================ |
+ |
+ If you want to set default values for `configure' scripts to share, |
+you can create a site shell script called `config.site' that gives |
+default values for variables like `CC', `cache_file', and `prefix'. |
+`configure' looks for `PREFIX/share/config.site' if it exists, then |
+`PREFIX/etc/config.site' if it exists. Or, you can set the |
+`CONFIG_SITE' environment variable to the location of the site script. |
+A warning: not all `configure' scripts look for a site script. |
+ |
+Operation Controls |
+================== |
+ |
+ `configure' recognizes the following options to control how it |
+operates. |
+ |
+`--cache-file=FILE' |
+ Use and save the results of the tests in FILE instead of |
+ `./config.cache'. Set FILE to `/dev/null' to disable caching, for |
+ debugging `configure'. |
+ |
+`--help' |
+ Print a summary of the options to `configure', and exit. |
+ |
+`--quiet' |
+`--silent' |
+`-q' |
+ Do not print messages saying which checks are being made. To |
+ suppress all normal output, redirect it to `/dev/null' (any error |
+ messages will still be shown). |
+ |
+`--srcdir=DIR' |
+ Look for the package's source code in directory DIR. Usually |
+ `configure' can determine that directory automatically. |
+ |
+`--version' |
+ Print the version of Autoconf used to generate the `configure' |
+ script, and exit. |
+ |
+`configure' also accepts some other, not widely useful, options. |
