+ GNU Pth - The GNU Portable Threads
+
+ INSTALL
+ =======
+
+ Overview
+ --------
+
+ To install the Pth library into /path/to/pth/{bin,lib,include,man}/
+ perform the following steps in your shell:
+
+ $ ./configure
+ --prefix=/path/to/pth
+ [--enable-batch]
+ [--enable-pthread]
+ [--enable-debug]
+ [--enable-profile]
+ [--enable-optimize]
+ [--enable-maintainer]
+ [--enable-tests]
+ [--disable-shared]
+ [--disable-static]
+ [--enable-syscall-soft]
+ [--enable-syscall-hard]
+ [--with-sfio[=DIR]]
+ [--with-ex[=DIR]]
+ [--with-dmalloc[=DIR]]
+ [--with-mctx-mth=ID]
+ [--with-mctx-dsp=ID]
+ [--with-mctx-stk=ID]
+ $ make
+ $ make test
+ $ make install
+
+ Pth Options
+ -----------
+
+ The supported options have the following meaning:
+
+ --prefix=DIR: installation path prefix
+ This sets the path prefix of installation tree. By default this
+ prefix is /usr/local. For fine-tuning the installation paths
+ run `./configure --help' and watch for the various path related
+ options.
+
+ --enable-batch: build in batch mode (default=no)
+ This enables batch building. Currently this does
+ nothing more than supressing some displayed hints.
+
+ --enable-maintainer: build maintainer targets (default=no)
+ This enables some maintainer build targets.
+ Not for use by end users.
+
+ --enable-tests: build test targets (default=yes)
+ This enables the building of test targets, i.e. the various
+ test_xxx programs. If you don't want to build these use
+ --disable-tests.
+
+ --enable-pthread: build with pthread library (default=no)
+ This enables the building and installation of the
+ POSIX Threads ("pthread") emulation API for Pth.
+ This per default forces --enable-syscall-soft.
+
+ --enable-debug: build for debugging (default=no)
+ This is for debugging Pth and only interesting
+ for developers.
+
+ --enable-profile: build for profiling (default=no)
+ This enables profiling with gprof and is only
+ interesting for developers.
+
+ --enable-optimize: build with optimization (default=no)
+ This enables optimization flags, mainly for GCC.
+
+ --disable-static: build static libraries (default=yes)
+ This disables the building of static libraries (libxx.a).
+
+ --disable-shared: build shared libraries (default=yes)
+ This disables the building of shared libraries (libxx.so).
+
+ --enable-syscall-soft: use soft system call mapping (default=no)
+ This enables the soft system call mapping for pth.h and pthread.h
+
+ --enable-syscall-hard: use hard system call mapping (default=no)
+ This enables the hard system call mapping inside pth_syscall.c which
+ means that wrappers for system calls are exported by libpth.
+
+ --with-sfio[=DIR]
+ This can be used to enable Sfio support (see pth_sfiodisc function) for
+ Pth. The paths to the include and library file of Sfio has to be either
+ given via CFLAGS and LDFLAGS or the DIR argument has to specify the root
+ of the Sfio installation tree. Sfio can be found at
+ http://www.research.att.com/sw/tools/sfio/.
+
+ --with-ex[=DIR]
+ This can be used to enable OSSP ex support (exception handling)
+ for Pth. The paths to the include and library file of OSSP ex has
+ to be either given via CFLAGS and LDFLAGS or the DIR argument has
+ to specify the root of the OSSP ex installation tree. OSSP ex can
+ be found at http://www.ossp.org/pkg/ex/.
+
+ --with-dmalloc[=DIR]
+ This can be used to enable Dmalloc support (debugging memory
+ allocations) for Pth. The paths to the include and library file of
+ Dmalloc has to be either given via CFLAGS and LDFLAGS or the DIR
+ argument has to specify the root of the Dmalloc installation tree.
+ Dmalloc can be found at http://www.dmalloc.com/.
+
+ The remaining three options are really for experts only. They force
+ particular variants for the machine context implementation. Be carefully
+ here: Not all possibly variants of the three knobs actually work (they could
+ not work, even when we want!).
+
+ --with-mctx-mth=ID [EXPERTS ONLY]
+ This forces Pth to use a particular machine context method.
+ Available variants are:
+ mcsc .... makecontext(2)/swapcontext(2)
+ sjlj .... setjmp(2)/longjmp(2)
+
+ --with-mctx-dsp=ID [EXPERTS ONLY]
+ This forces Pth to use a particular machine context dispatching
+ approach. Available variants are:
+ sc ...... swapcontext(2)
+ ssjlj ... sigsetjmp(3)/siglongjmp(3)
+ sjlj .... setjmp(3)/longjmp(3) (signal mask aware)
+ usjlj ... _setjmp(3)/_longjmp(3) (signal mask aware)
+ sjlje ... setjmp(3)/longjmp(3) [emulated = plus sigprocmask(2)]
+ sjljlx .. setjmp(3)/longjmp(3), specific for anchient Linux version
+ sjljisc . setjmp(3)/longjmp(3), specific for Interactive Unix (ISC)
+ sjljw32 . setjmp(3)/longjmp(3), specific for Win32/CygWin
+
+ --with-mctx-stk=ID [EXPERTS ONLY]
+ This forces Pth to use a particular machine context stack setup
+ approach. Available variants are:
+ none .... no standard stack setup (only for some sjljXXX above)
+ mc ...... makecontext(2)
+ sas ..... sigaltstack(2)
+ ss ...... sigstack(2)
+
+ Compiler Flags
+ --------------
+
+ 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.
+
+ 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.
+
+ 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.
