Installation From SVN ===================== If you intend to compile PrBoom from a source tar file, such as prboom-2.5.0.tar.gz, as opposed to SVN, skip to the "Basic Installation" section. 1. Install and configure deutex. If deutex is already installed and configured skip to step 2. a. Install deutex from http://www.teaser.fr/~amajorel/deutex b. Set the DOOMWADDIR environment variable to the directory that contains the IWAD files: export DOOMWADDIR=/usr/local/share/games/doom 2. 'cd' to a suitable parent directory for the PrBoom distribution: cd /usr/local/src 3. Extract the PrBoom distribution from SVN: svn co http://www.crowproductions.de/repos/prboom/trunk/prboom2 4. 'cd' to the directory containing the PrBoom distribution (the directory this file is in): cd prboom2 5. Run the 'bootstrap' script in order to create the 'configure' script. ./bootstrap If you get this error: aclocal: configure.ac: 153: macro `AM_PATH_SDL' not found in library Then you have to locate sdl.m4 and copy it to ./autotools/sdl.m4 in your prboom directory. 6. If the 'configure' script was created by step 5 then proceed to the "Basic Installation" section. Basic Installation ================== 1. To compile PrBoom, you need the SDL development headers and libraries installed (SDL, SDL_mixer, SDL_net). See http://prboom.sourceforge.net/linux.html for information on downloading the right libraries for your system. 2. `cd' to the directory containing the PrBoom distribution (the directory this file is in). Type `./configure' to configure PrBoom 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. 3. Type `make' to compile PrBoom. This may take some time; while it's compiling I suggest you read the README, or maybe go and look for some good doom levels to play when it's finished :-). This should work on all Linux systems, but systems that have a make utility other than GNU make may have problems. E.g. you might need to install GNU make, and then use it instead of make for these instructions. I have tested BSD pmake and it works fine. 4. Type `make install-strip' as root, to install the programs, data files and man pages for PrBoom. If you don't have root access on the machine, you should ask the syadmin to do this and the next step for you. 5. Copy your Doom, Doom 2, Ultimate Doom or Final Doom IWAD (doom.wad or doom2.wad) to /usr/local/share/games/doom/ (or symlink it from there). Or if you don't have any of those, use the shareware IWAD, which you can get from http://www.doomworld.com/ or http://www.idsoftware.com/. If you have a system with many users, you should read the license for your version of Doom, and make sure only those users allowed to use it can access the IWAD file. 6. You can remove the program binaries and object files from the source 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. 7. PrBoom is now ready for use. If /usr/local/games is in your path, you can just run prboom; otherwise give the full path. See the README file for information about getting the Timidity patches needed for music support, and more. Building an RPM =============== If you are on a system which uses the RPM packaging format, you might prefer to build an RPM containing the PrBoom binaries rather than installing them directly. Follow steps 1 and 2 above, then run a "make rpm". This performs the usual proceedure for building the rpm in /usr/src/redhat/. Note that the RPM sets its own parameters to ./configure; if you want to override them you'll have to edit the build scripts yourself. Note that to get the correct permissions, you either have to run this process as root, or use the wrapper program fakeroot (version 0.4.5 or later - grab it from the Debian source archive) and make sure you have permissions to the RPM build area. Installation Details ==================== 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.ac' is used to create `configure' by a program called `autoconf'. You only need `configure.ac' if you want to change it or regenerate `configure' using a newer version of `autoconf'. 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.
