| | | Compilers and Options |
| | | ===================== |
| | | |
| | | Some systems require unusual options for compilation or linking that |
| | | the `configure' script does not know about. Run `./configure --help' |
| | | the 'configure' script does not know about. Run './configure --help' |
| | | for details on some of the pertinent environment variables. |
| | | |
| | | You can give `configure' initial values for configuration parameters |
| | | by setting variables in the command line or in the environment. Here |
| | | is an example: |

| | |
| | | |
| | | 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 can use GNU `make'. `cd' to the |
| | | own directory. To do this, you can use GNU 'make'. 'cd' to the |
| | | directory where you want the object files and executables to go and run |

| | | is known as a "VPATH" build. |

| | | On MacOS X 10.5 and later systems, you can create libraries and |

| | | Installation Names |
| | | ================== |
| | | |
| | | By default, `make install' installs the package's commands under |
| | | `/usr/local/bin', include files under `/usr/local/include', etc. You |
| | | can specify an installation prefix other than `/usr/local' by giving |

| | | can specify an installation prefix other than '/usr/local' by giving |
| | | 'configure' the option '--prefix=PREFIX', where PREFIX must be an |
| | | absolute file name. |
| | | |
| | | You can specify separate installation prefixes for |
| | | architecture-specific files and architecture-independent files. If you |

| | | PREFIX as the prefix for installing programs and libraries. |
| | | Documentation and other data files still use the regular prefix. |
| | | |
| | | In addition, if you use an unusual directory layout you can give |
| | | options like `--bindir=DIR' 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. In general, the |
| | | default for these options is expressed in terms of `${prefix}', so that |
| | | specifying just `--prefix' will affect all of the other directory |
| | | options like '--bindir=DIR' to specify different values for particular |
| | | kinds of files. Run 'configure --help' for a list of the directories |
| | | you can set and what kinds of files go in them. In general, the default |
| | | for these options is expressed in terms of '${prefix}', so that |
| | | specifying just '--prefix' will affect all of the other directory |
| | | specifications that were not explicitly provided. |
| | | |
| | | The most portable way to affect installation locations is to pass the |
| | | correct locations to `configure'; however, many packages provide one or |
| | | correct locations to 'configure'; however, many packages provide one or |
| | | both of the following shortcuts of passing variable assignments to the |
| | | `make install' command line to change installation locations without |
| | | 'make install' command line to change installation locations without |
| | | having to reconfigure or recompile. |
| | | |
| | | The first method involves providing an override variable for each |
| | | affected directory. For example, `make install |
| | | affected directory. For example, 'make install |
| | | prefix=/alternate/directory' will choose an alternate location for all |
| | | directory configuration variables that were expressed in terms of |
| | | `${prefix}'. Any directories that were specified during `configure', |
| | | but not in terms of `${prefix}', must each be overridden at install |
| | | time for the entire installation to be relocated. The approach of |
| | | makefile variable overrides for each directory variable is required by |
| | | the GNU Coding Standards, and ideally causes no recompilation. |
| | | However, some platforms have known limitations with the semantics of |
| | | shared libraries that end up requiring recompilation when using this |
| | | method, particularly noticeable in packages that use GNU Libtool. |

| | | noticeable in packages that use GNU Libtool. |
| | | |
| | | The second method involves providing the `DESTDIR' variable. For |
| | | example, `make install DESTDIR=/alternate/directory' will prepend |
| | | `/alternate/directory' before all installation names. The approach of |

| | | does not work on platforms that have drive letters. On the other hand, |
| | | it does better at avoiding recompilation issues, and works well even |
| | | when some directory options were not specified in terms of `${prefix}' |

| | | 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 |

| | | overridden with `make V=1'; while running `./configure |

| | | Specifying the System Type |
| | | ========================== |
| | | |
| | | There may be some features `configure' cannot figure out |
| | | There may be some features 'configure' cannot figure out |
| | | automatically, but needs to determine by the type of machine the package |
| | | will run on. Usually, assuming the package is built to be run on the |

| | | _same_ architectures, 'configure' can figure that out, but if it prints |
| | | a message saying it cannot guess the machine type, give it the |
| | | `--build=TYPE' option. TYPE can either be a short name for the system |
| | | type, such as `sun4', or a canonical name which has the form: |

| | | |
| | | 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. |

| | | |
| | | Defining Variables |
| | | ================== |
| | | |
| | | Variables not defined in a site shell script can be set in the |
| | | environment passed to `configure'. However, some packages may run |
| | | environment passed to 'configure'. However, some packages may run |
| | | configure again during the build, and the customized values of these |
| | | variables may be lost. In order to avoid this problem, you should set |
| | | them in the `configure' command line, using `VAR=value'. For example: |
