Brief Installation Instructions =========================================== To build Guile on unix, there are two basic steps: 1. Type "./configure", to configure the package for your system. 2. Type "make", to build the package. Generic instructions for configuring and compiling GNU distributions are included below. (For instructions how to install SLIB, the scheme procedure library, see below.) Special Instructions For Some Systems ===================================== We would like Guile to build on all systems using the simple instructions above, but it seems that a few systems still need special treatment. If you can send us fixes for these problems, we'd be grateful. SunOS 4.1: Guile's shared library support seems to be confused, but hey; shared libraries are confusing. You may need to configure Guile with a command like: ./configure --disable-shared For more information on `--disable-shared', see below, "Flags Accepted by Configure". HP/UX: GCC 2.7.2 (and maybe other versions) have trouble creating shared libraries if they depend on any non-shared libraries. GCC seems to have other problems as well. To work around this, we suggest you configure Guile to use the system's C compiler: CC=cc ./configure NetBSD: Perry Metzger says, "Guile will build under NetBSD only using gmake -- the native make will not work. (gmake is in our package system, so this will not be a problem when we packagize 1.3.)" Flags Accepted by Configure =============================================== If you run the configure script with no arguments, it should examine your system and set things up appropriately. However, there are a few switches specific to Guile you may find useful in some circumstances. --enable-maintainer-mode If you have automake, autoconf, and libtool installed on your system, this switch causes configure to generate Makefiles which know how to automatically regenerate configure scripts, makefiles, and headers, when they are out of date. The README file says which versions of those tools you will need. --with-threads --- Build with thread support Build a Guile executable and library that supports cooperative threading. If you use this switch, Guile will also build and install the QuickThreads non-preemptive threading library, libqthreads, which you will need to link into your programs after libguile. When you use `guile-config', you will pick up all neccessary linker flags automatically. Cooperative threads are not yet thoroughly tested; once they are, they will be enabled by default. The interaction with blocking I/O is pretty ad hoc at the moment. In our experience, bugs in the thread support do not affect you if you don't actually use threads. --with-modules --- Specify statically linked `modules' Guile can dynamically load `plugin modules' during runtime, using facilities provided by libtool. Not all platforms support this, however. On these platforms, you can statically link the plugin modules into libguile when Guile itself is build. XXX - how does one specify the modules? --enable-deprecated=LEVEL --- Control the inclusion of deprecated features. You can select between different behaviours via the LEVEL argument: a value of "no" will omit all deprecated features and you will get "undefined reference", "variable unbound" or similar errors when you try to use them. All other values will include all deprecated features. The LEVEL argument is used as the default value for the environment variable GUILE_WARN_DEPRECATED. See the README for more information. The default is to get a vague warning at program exit if deprecated features were used: --enable-deprecated=yes --enable-deprecated=summary To get a detailed warning at first use of a deprecated feature: --enable-deprecated=detailed To get no warnings: [ FIXME: this doesn't seem to be possible, without setting the environment variable ] To omit deprecated features completely and irrevokably: --enable-deprecated=no --disable-shared --- Do not build shared libraries. --disable-static --- Do not build static libraries. Normally, both static and shared libraries will be built if your system supports them. --enable-debug-freelist --- Enable freelist debugging. This enables a debugging version of SCM_NEWCELL(), and also registers an extra primitive, the setter `gc-set-debug-check-freelist!'. Configure with the --enable-debug-freelist option to enable the gc-set-debug-check-freelist! primitive, and then use: (gc-set-debug-check-freelist! #t) # turn on checking of the freelist (gc-set-debug-check-freelist! #f) # turn off checking Checking of the freelist forces a traversal of the freelist and a garbage collection before each allocation of a cell. This can slow down the interpreter dramatically, so the setter should be used to turn on this extra processing only when necessary. --enable-debug-malloc --- Enable malloc debugging. Include code for debugging of calls to scm_must_malloc/realloc/free. Checks that 1. objects freed by scm_must_free has been mallocated by scm_must_malloc 2. objects reallocated by scm_must_realloc has been allocated by scm_must_malloc 3. reallocated objects are reallocated with the same what string But, most importantly, it records the number of allocated objects of each kind. This is useful when searching for memory leaks. A Guile compiled with this option provides the primitive `malloc-stats' which returns an alist with pairs of kind and the number of objects of that kind. --enable-guile-debug --- Include internal debugging functions --disable-arrays --- omit array and uniform array support --disable-posix --- omit posix interfaces --disable-networking --- omit networking interfaces --disable-regex --- omit regular expression interfaces Using Guile Without Installing It ========================================= If you want to run Guile without installing it, set the environment variable `GUILE_LOAD_PATH' to a colon-separated list of directories, including the directory containing this INSTALL file. If you used a separate build directory, you'll need to include the build directory in the path as well. For example, suppose the Guile distribution unpacked into a directory called `/home/jimb/guile-snap' (so the full name of this INSTALL file would be `/home/jimb/guile-snap/INSTALL'). Then you might say, if you're using Bash or any other Bourne shell variant, export GUILE_LOAD_PATH=/home/jimb/guile-snap or if you're using CSH or one of its variants: setenv GUILE_LOAD_PATH /home/jimb/guile-snap Installing SLIB =========================================================== In order to use SLIB from Guile you basically only need to put the `slib' directory _in_ one of the directories on Guile's load path. The standard installation is: 1. Obtain slib from http://www-swiss.ai.mit.edu/~jaffer/SLIB.html 2. Put it in Guile's data directory, that is the directory printed when you type guile-config info pkgdatadir at the shell prompt. This is normally `/usr/local/share/guile', so the directory will normally have full path `/usr/local/share/guile/slib'. 3. Start guile as a user with write access to the data directory and type (use-modules (ice-9 slib)) at the Guile prompt. This will generate the slibcat catalog next to the slib directory. SLIB's `require' is provided by the Guile module (ice-9 slib). Example: (use-modules (ice-9 slib)) (require 'primes) (prime? 7) Generic Instructions for Building Auto-Configured Packages ================ To compile this package: 1. Configure the package for your system. In the directory that this file is in, type `./configure'. 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. The `configure' shell script attempts to guess correct values for various system-dependent variables used during compilation, and creates the Makefile(s) (one in each subdirectory of the source directory). In some packages it creates a C header file containing system-dependent definitions. It also creates a file `config.status' that you can run in the future to recreate the current configuration. Running `configure' takes a minute or two. To compile the package in a different directory from the one containing the source code, you must use GNU make. `cd' to the directory where you want the object files and executables to go and run `configure' with the option `--srcdir=DIR', where DIR is the directory that contains the source code. Using this option is actually unnecessary if the source code is in the parent directory of the one in which you are compiling; `configure' automatically checks for the source code in `..' if it does not find it in the current directory. By default, `make install' will install the package's files in /usr/local/bin, /usr/local/lib, /usr/local/man, etc. You can specify an installation prefix other than /usr/local by giving `configure' the option `--prefix=PATH'. Alternately, you can do so by changing the `prefix' variable in the Makefile that `configure' creates (the Makefile in the top-level directory, if the package contains subdirectories). You can specify separate installation prefixes for machine-specific files and machine-independent files. If you give `configure' the option `--exec_prefix=PATH', the package will use PATH as the prefix for installing programs and libraries. Normally, all files are installed using the same prefix. `configure' ignores any other arguments that you give it. If your system requires unusual options for compilation or linking that `configure' doesn't know about, you can give `configure' initial values for some variables by setting them in the environment. In Bourne-compatible shells, you can do that on the command line like this: CC='gcc -traditional' DEFS=-D_POSIX_SOURCE ./configure The `make' variables that you might want to override with environment variables when running `configure' are: (For these variables, any value given in the environment overrides the value that `configure' would choose:) CC C compiler program. Default is `cc', or `gcc' if `gcc' is in your PATH. INSTALL Program to use to install files. Default is `install' if you have it, `cp' otherwise. INCLUDEDIR Directory for `configure' to search for include files. Default is /usr/include. (For these variables, any value given in the environment is added to the value that `configure' chooses:) DEFS Configuration options, in the form '-Dfoo -Dbar ...' LIBS Libraries to link with, in the form '-lfoo -lbar ...' If you need to do unusual things to compile the package, we encourage you to teach `configure' how to do them and mail the diffs to the address given in the README so we can include them in the next release. 2. Type `make' to compile the package. 3. Type `make install' to install programs, data files, and documentation. 4. You can remove the program binaries and object files from the source directory by typing `make clean'. To also remove the Makefile(s), the header file containing system-dependent definitions (if the package uses one), and `config.status' (all the files that `configure' created), type `make distclean'. The file `configure.in' is used as a template to create `configure' by a program called `autoconf'. You will only need it if you want to regenerate `configure' using a newer version of `autoconf'.
