pike.git/README-GIT:1:    + HOW TO BUILD PIKE FROM GIT +  + If you like to live at the bleeding edge you can download Pike from + git with all the latest additions from the developers. There are two + major branches in the archive, the latest stable branch and latest + 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. +  + Keep in mind that the git versions are under heavy development and + have not been tested nearly as well as the offcial releases. You use + the code AT YOUR OWN RISK. +  +  + DEPENDENCIES +  + Building from git 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 GIT +  + 1. Get a recent version of git (1.7.2 or later). +  + 2. Clone the git repository with +  +  git clone git://pike-git.lysator.liu.se/pike.git +  +  + The top-level makefile (in this directory, not the src directory) has + all the magic you need to build Pike directly from git. Just type + 'make'. It is preferable to build from the toplevel since it avoids + contaminating the source tree with object files and other generated + files. +  + Other interesting make targets are: +  + 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 +  installed Pike. + just_verify Run the testsuite directly with the Pike binary in +  the build tree. + run_hilfe Run hilfe without installing Pike. + pike Build only the Pike core, do not recurse into the +  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 +  build tree once. It's not run by default. + source Prepare the source tree for compilation without +  the need for a preexisting installed Pike. + force_autoconfig Force a build of the configure scripts. This is +  useful e.g. if a new module directory is added in +  the git. + force_configure Force configure to be run (recursively). + reconfigure Remove the cached results from previous configure +  runs and rerun configure recursively. If you have +  installed a new library and want Pike to detect it +  then the simplest way is to use this target. + dump_modules Dump the Pike modules directly in the build tree. +  That makes Pike load faster if it's run directly +  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. + 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 +  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 git write access). Please do not +  check in the generated files. + clean Remove all the built binary files. + gitclean Remove all files that are generated automatically, +  i.e. bring the tree back to the state as if it +  was checked out from the git. +  +  + CONFIGURE OPTIONS AND BUILD VARIABLES +  + 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 git 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 +  --without-bignums) + --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 +  also the section 'If It Doesn't Work' below) + --without-zlib compile without gzip compression libary +  support + --without-dynamic-modules compile statically, no dynamic loading +  used (makes the binary larger) + --without-mysql compile without mysql support + --with-profiling enables profiling Pike code but slows +  down interpreter a little + --with-poll use poll instead of select + --with-dmalloc compile with memory tracking, makes Pike +  very slow, use for debugging only. + --with-security enable internal object security system +  +  + 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 +  -L/usr/gnu/lib and -R/usr/gnu/lib +  +  + MANUAL BUILDING +  + Instructions if you want to do the build more manually: +  + 1. cd src ; ./run_autoconfig +  This creates configure files and Makefile.in files. +  + 2. Create a build directory an cd to it. Do NOT build in the source +  dir, doing so will make it impossible to do 'make export' later. +  + 3. Run the newly created configure file located in the src dir from +  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... +  + 4. If needed, edit config.h and Makefile to suit your purposes. We +  have tried to make it so that you don't have to change config.h or +  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 +  possible, use gnu make, gcc, gnu sed and bison. +  + 5. Run 'make' +  This builds Pike. +  + 6. Optionally, run 'make verify' to check that the compiled driver +  works as it should (might be a good idea). This will take a little +  time and use quite a lot of memory, because the test program is +  quite large. If everything works out fine no extra messages are +  written. +  + 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. +  + After doing this, DO NOT commit the generated files. They are placed + in .gitignore files so you shouldn't have to bother with them. +  +  + IF IT DOESN'T WORK +  +  o Try again. +  +  o Try running 'make depend'. +  +  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: +  +  $ CONFIG_SHELL=full_path_for_bash +  $ export CONFIG_SHELL +  $ $CONFIG_SHELL ./configure +  +  o If you are not using GNU make, compile in the source dir rather +  than using a separate build dir. +  +  o ./configure relies heavily on sed, if you have several sed in your +  path try another sed (preferably gnu sed). +  +  o configure might have done something wrong, check machine.h and +  report any errors back to us. +  +  o Your gmp/gdbm libraries might not be working or incorrectly +  installed; start over by running configure with the appropriate +  --without-xxx arguments. Also note that threads might give +  problems with I/O and signals. If so you need to run configure +  --without-threads. +  +  o Try a different compiler, malloc, compiler-compiler and/or make +  (if you have any other). +  +  + BUGS +  + 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: +  +  o The Pike version. (Try pike --version or look in src/version.h) +  o What kind of system hardware/software you use (OS, compiler, etc.) +  o The piece of code that crashes or bugs, preferably in a very +  small Pike-script with the bug isolated. Please send a complete +  running example of something that causes the bug. +  o A description of what it is that bugs and when. +  o If you know how, then also give us a backtrace and dump of vital +  variables at the point of crash. +  o Or, if you found the error and corrected it, just send us the +  bugfix along with a description of what you did and why.   Newline at end of file added.
