Welcome. + +This file contains instructions for compiling and installing the Hurd +from your existing Hurd system. + +If you are running any other kind of system whatsoever, these +instructions will *NOT* be sufficient. The file INSTALL-cross +contains some past instructions for doing so, but it's too much +trouble to maintain them and make them easier. Your best bet is to +start with a running Hurd system already. + +The Hurd and the GNU C Library each need each other in order to +compile. If you are installing both, please follow the directions +"Building the Hurd and libc together". If the C library version you +want to use is already installed, and you know both it and this +version of the Hurd will interoperate together, then see the +instructions "Bulding the Hurd by itself" below. + +The Hurd version 0.0 is known to work with version XXX of the library. + + +Configuring the Hurd +==================== + +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'. + + +Building the Hurd, Mach4, and libc together +=========================================== + +1. Configure mach4. + +2. `make' mach4. + +3. Do `make install' in <mach4-build>/mig. ONLY. + +4. Do `make install' in <mach4-build>/include. ONLY. + +5. Configure the Hurd with `configure'. + +6. In the Hurd directory, type `make install-hdrs'. + +7. Configure libc. + +8. `make install' libc. + +9. `make' and `make install' Hurd. + +10. `make install' mach4. + + +Building the Hurd and libc together +=================================== + +1. `cd' to the directory containing the Hurd's source code and type + `./configure' to configure the Hurd. + +2. Type `make install-hdrs' to install the Hurd's header files. + +3. Follow the instructions in the GNU C Library for configuring and + installing GNU libc. + +4. Return to the directory containing the Hurd's source code and type + `make' to compile the Hurd. + +5. Type `make install' to install the Hurd. + + +Building the Hurd by itself +=========================== + +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 awhile. 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. + +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. `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 `..'. + +Installation Names +================== + +By default, `make install' will install the package's files in `/bin', +`/man', etc. You can specify an installation prefix 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'. + +Please note, however, that the Hurd knows where it is located in the +filesystem. If you have installed it in an unusual location, the +system might not work properly, or at all. The chief utility of these +options for the Hurd is to allow you to "install" in some alternate +location, and then copy these to the actual root filesystem later. + +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. + +`--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. + |
