3cc1092002-04-06Mikael Brandström HOW TO BUILD PIKE FROM CVS
ef3d962001-10-16Martin Nilsson 
0baf3b2007-03-12Johan Sundström If you like to live at the bleeding edge you can download Pike from CVS with all the latest additions from the developers. There are two
9a06b42002-04-08Mikael Brandström major branches in the archive, the latest stable branch and latest
0baf3b2007-03-12Johan Sundström development branch. Stable versions have an even minor version number, i.e. 7.0.x, 7.2.x, 7.4.x, whereas the development branches have an odd minor version.
9a06b42002-04-08Mikael Brandström 
0baf3b2007-03-12Johan Sundström Keep in mind that the CVS versions are under heavy development and
27b6d62002-04-11Martin Stjernholm have not been tested nearly as well as the offcial releases. You use
0baf3b2007-03-12Johan Sundström the code AT YOUR OWN RISK.

0baf3b2007-03-12Johan Sundström DEPENDENCIES Building from CVS requires the same tools as building from a source distribution (gnu m4, bison and a C compiler, suggested also GNU make and libz), and then some. In addition to thosee requirements, you need a working Pike, autoconf and gcc (to generate the dependency files; another compiler can be used to do the actual compilation). Not all autoconf versions meet Pike's requirements. Autoconf version 2.13 and 2.52 are known to work. Versions 2.53 through at least 2.57 are known to not work. CHECKING OUT PIKE FROM CVS
27b6d62002-04-11Martin Stjernholm 
9a06b42002-04-08Mikael Brandström 1. Get a recent version of cvs.
27b6d62002-04-11Martin Stjernholm 
0baf3b2007-03-12Johan Sundström 2. Login to the CVS server:
9a06b42002-04-08Mikael Brandström 
f8cc4d2002-07-24Martin Stjernholm  cvs -d :pserver:anon@cvs.roxen.com:/cvs login
9a06b42002-04-08Mikael Brandström 
27b6d62002-04-11Martin Stjernholm  Just hit enter on the password prompt.
9a06b42002-04-08Mikael Brandström 3. Check out the source:
ef3d962001-10-16Martin Nilsson 
8613e22007-01-02Peter Bortas  cvs -z3 -d :pserver:anon@cvs.roxen.com:/cvs co Pike/7.7
9a06b42002-04-08Mikael Brandström 
8613e22007-01-02Peter Bortas  substitute 7.7 for whatever version you want to get.
9a06b42002-04-08Mikael Brandström  The top-level makefile (in this directory, not the src directory) has
58ad4e2003-11-05Martin Nilsson all the magic you need to build Pike directly from CVS. Just type
27b6d62002-04-11Martin Stjernholm 'make'. It is preferable to build from the toplevel since it avoids
9a06b42002-04-08Mikael Brandström contaminating the source tree with object files and other generated files.
3cc1092002-04-06Mikael Brandström Other interesting make targets are:
f8cc4d2002-07-24Martin Stjernholm install Compile and install in default location. install_interactive Interactive install. tinstall Test install, i.e. install in build directory. verify Do a test install and run the testsuite with the
58ad4e2003-11-05Martin Nilsson  installed Pike. just_verify Run the testsuite directly with the Pike binary in
f8cc4d2002-07-24Martin Stjernholm  the build tree.
58ad4e2003-11-05Martin Nilsson run_hilfe Run hilfe without installing Pike. pike Build only the Pike core, do not recurse into the
f8cc4d2002-07-24Martin Stjernholm  module directories. documentation Build the reference documentation from the source. See the refdoc subdirectory. depend Build the files that tracks dependencies between the source files. This is necessary to ensure correct rebuilding if some of the source files change, but not if you only intend to use the
59ecf52003-02-20Martin Stjernholm  build tree once. It's not run by default.
692ab32003-03-21Martin Stjernholm source Prepare the source tree for compilation without
58ad4e2003-11-05Martin Nilsson  the need for a preexisting installed Pike.
692ab32003-03-21Martin Stjernholm force_autoconfig Force a build of the configure scripts. This is
f8cc4d2002-07-24Martin Stjernholm  useful e.g. if a new module directory is added in the CVS.
692ab32003-03-21Martin Stjernholm force_configure Force configure to be run (recursively). If
58ad4e2003-11-05Martin Nilsson  you've installed a new library and want Pike to
f8cc4d2002-07-24Martin Stjernholm  detect it, then the simplest way is to remove config.cache in the build directory (or perhaps just delete the relevant variables in it) and then use this target.
692ab32003-03-21Martin Stjernholm dump_modules Dump the Pike modules directly in the build tree.
58ad4e2003-11-05Martin Nilsson  That makes Pike load faster if it's run directly
f8cc4d2002-07-24Martin Stjernholm  from there, e.g. through the bin/pike script (see below). These dumped modules are not used for anything else. After this has been run once, any changed Pike modules will be redumped automatically by the main build targets.
692ab32003-03-21Martin Stjernholm undump_modules Remove any modules dumped by dump_modules, and remove the redump step described above. force_dump_modules Force all Pike modules to be redumped, not just
f8cc4d2002-07-24Martin Stjernholm  those whose source files have changed. snapshot Create a snapshot export tarball. export Create a source dist and bump up the build number (if you have cvs write access). Please do not check in the generated files.
692ab32003-03-21Martin Stjernholm clean Remove all the built binary files. cvsclean Remove all files that are generated automatically, i.e. bring the tree back to the state as if it
f8cc4d2002-07-24Martin Stjernholm  was checked out from the CVS.

0baf3b2007-03-12Johan Sundström  CONFIGURE OPTIONS AND BUILD VARIABLES
27b6d62002-04-11Martin Stjernholm If you want to pass arguments to the configure script (see below), the simplest way is to use the CONFIGUREARGS variable, like this: make CONFIGUREARGS="--prefix=/usr/local/my-pike --with-security" The arguments passed through CONFIGUREARGS are remembered in the build tree and reused if CONFIGUREARGS is undefined or the empty string. You therefore don't need to repeat them every time, but you can still change them later if you like. There's a special case for the --help argument: If CONFIGUREARGS is set to '--help' then the help text from the configure script is shown and nothing else is done, and the stored CONFIGUREARGS setting isn't affected. The build targets also creates a script 'pike' in the bin subdirectory which runs the built Pike directly without installing it first. If you want to use Pike this way (which is mainly useful if you update from CVS often), you should consider doing 'make dump_modules' to make it start faster. Some options for the configure script are: --prefix=/foo/bar if you want to install Pike in /foo/bar, default is /usr/local. --without-gdbm compile without gdbm support --without-bignums disable support for large integers --without-gmp compile without gmp support (implies
f8cc4d2002-07-24Martin Stjernholm  --without-bignums)
27b6d62002-04-11Martin Stjernholm --with-rtldebug compile with runtime debug checks --without-cdebug compile without debug symbols (-g) --with-debug same as --with-rtldebug --with-cdebug --without-debug same as --without-rtldebug --without-cdebug --without-copt compile without -O2 --without-threads compile without threads support (see
f8cc4d2002-07-24Martin Stjernholm  also the section 'If It Doesn't Work' below)
27b6d62002-04-11Martin Stjernholm --without-zlib compile without gzip compression libary support --without-dynamic-modules compile statically, no dynamic loading
f8cc4d2002-07-24Martin Stjernholm  used (makes the binary larger)
27b6d62002-04-11Martin Stjernholm --without-mysql compile without mysql support
58ad4e2003-11-05Martin Nilsson --with-profiling enables profiling Pike code but slows
27b6d62002-04-11Martin Stjernholm  down interpreter a little --with-poll use poll instead of select
58ad4e2003-11-05Martin Nilsson --with-dmalloc compile with memory tracking, makes Pike
27b6d62002-04-11Martin Stjernholm  very slow, use for debugging only. --with-security enable internal object security system
0baf3b2007-03-12Johan Sundström 
27b6d62002-04-11Martin Stjernholm You might also want to set the following environment variables: CFLAGS Put extra flags for your C compiler here. CPPFLAGS Put extra flags for your C preprocessor here (such as -I/usr/gnu/include) LDFLAGS Put extra flags to your linker here, such as
f8cc4d2002-07-24Martin Stjernholm  -L/usr/gnu/lib and -R/usr/gnu/lib
27b6d62002-04-11Martin Stjernholm  MANUAL BUILDING Instructions if you want to do the build more manually: 1. cd src ; ./run_autoconfig
ef3d962001-10-16Martin Nilsson  This creates configure files and Makefile.in files.
27b6d62002-04-11Martin Stjernholm 2. Create a build directory an cd to it. Do NOT build in the source
73c4fb2001-11-05Martin Nilsson  dir, doing so will make it impossible to do 'make export' later.
ef3d962001-10-16Martin Nilsson 
27b6d62002-04-11Martin Stjernholm 3. Run the newly created configure file located in the src dir from
73c4fb2001-11-05Martin Nilsson  the build dir. Make sure to use an absolute path! This creates the Makefiles you need, e.g. Makefile from Makefile.in and machine.h from machine.h.in. If you don't use an absolute path the debug information will be all warped...
ef3d962001-10-16Martin Nilsson 
58ad4e2003-11-05Martin Nilsson 4. If needed, edit config.h and Makefile to suit your purposes. We
67f8202002-04-11Johan Sundström  have tried to make it so that you don't have to change config.h or
3a26752002-02-15Johan Sundström  Makefile at all. If you need to do what you consider 'unnecessary changes' then mail us and we'll try to fit it into configure. If
27b6d62002-04-11Martin Stjernholm  possible, use gnu make, gcc, gnu sed and bison.
ef3d962001-10-16Martin Nilsson 
58ad4e2003-11-05Martin Nilsson 5. Run 'make' This builds Pike.
ef3d962001-10-16Martin Nilsson 
58ad4e2003-11-05Martin Nilsson 6. Optionally, run 'make verify' to check that the compiled driver
73c4fb2001-11-05Martin Nilsson  works as it should (might be a good idea). This will take a little
3a26752002-02-15Johan Sundström  time and use quite a lot of memory, because the test program is
73c4fb2001-11-05Martin Nilsson  quite large. If everything works out fine no extra messages are written.
ef3d962001-10-16Martin Nilsson 
58ad4e2003-11-05Martin Nilsson 7) If you want to install Pike, write 'make install'. This will put your Pike in <prefix>/pike/<version>/. This way, you can install many Pike versions in parallell on the system if you want to. To put it below <prefix> directly, as other packages usually do, run 'make INSTALLARGS="--traditional" install' instead.
ef3d962001-10-16Martin Nilsson 
27b6d62002-04-11Martin Stjernholm After doing this, DO NOT commit the generated files. They are placed in .cvsignore files so you shouldn't have to bother with them.
ef3d962001-10-16Martin Nilsson 
27b6d62002-04-11Martin Stjernholm  IF IT DOESN'T WORK
ef3d962001-10-16Martin Nilsson  o Try again.
58ad4e2003-11-05Martin Nilsson  o Try running 'make depend'.
27b6d62002-04-11Martin Stjernholm  o Your sh might be too buggy to run ./configure (this is the case on A/UX). Try using bash, zsh or possibly ksh. To use bash, first run /bin/sh and type:
ef3d962001-10-16Martin Nilsson  $ CONFIG_SHELL=full_path_for_bash $ export CONFIG_SHELL $ $CONFIG_SHELL ./configure
73c4fb2001-11-05Martin Nilsson  o If you are not using GNU make, compile in the source dir rather than using a separate build dir.
ef3d962001-10-16Martin Nilsson 
73c4fb2001-11-05Martin Nilsson  o ./configure relies heavily on sed, if you have several sed in your
3a26752002-02-15Johan Sundström  path try another sed (preferably gnu sed).
ef3d962001-10-16Martin Nilsson 
73c4fb2001-11-05Martin Nilsson  o configure might have done something wrong, check machine.h and
3a26752002-02-15Johan Sundström  report any errors back to us.
ef3d962001-10-16Martin Nilsson 
73c4fb2001-11-05Martin Nilsson  o Your gmp/gdbm libraries might not be working or incorrectly
3a26752002-02-15Johan Sundström  installed; start over by running configure with the appropriate
73c4fb2001-11-05Martin Nilsson  --without-xxx arguments. Also note that threads might give problems with I/O and signals. If so you need to run configure --without-threads.
ef3d962001-10-16Martin Nilsson 
3a26752002-02-15Johan Sundström  o Try a different compiler, malloc, compiler-compiler and/or make (if you have any other).
ef3d962001-10-16Martin Nilsson  BUGS
27b6d62002-04-11Martin Stjernholm If you find a bug in the interpreter, typically if Pike dumps core, the first thing to do is to make sure it is compiled with the --with-rtldebug configure flag. If not, reconfigure and recompile with that and see if you get another error. When you've done this, please report the bug to us at http://community.roxen.com/crunch/ and include as much as you can muster of the following:
ef3d962001-10-16Martin Nilsson 
27b6d62002-04-11Martin Stjernholm  o The Pike version. (Try pike --version or look in src/version.h)
ef3d962001-10-16Martin Nilsson  o What kind of system hardware/software you use (OS, compiler, etc.)
73c4fb2001-11-05Martin Nilsson  o The piece of code that crashes or bugs, preferably in a very
58ad4e2003-11-05Martin Nilsson  small Pike-script with the bug isolated. Please send a complete
27b6d62002-04-11Martin Stjernholm  running example of something that causes the bug.
ef3d962001-10-16Martin Nilsson  o A description of what it is that bugs and when.
3a26752002-02-15Johan Sundström  o If you know how, then also give us a backtrace and dump of vital
73c4fb2001-11-05Martin Nilsson  variables at the point of crash.
3a26752002-02-15Johan Sundström  o Or, if you found the error and corrected it, just send us the
73c4fb2001-11-05Martin Nilsson  bugfix along with a description of what you did and why.
