This assumes if you're building for Linux that your kernel source is in /usr/src/linux. Otherwise, please read on. Building OpenAFS on UNIX and Linux ---------------------------------- A Configuring Uncompress the source into a directory of your choice. A directory in afs space is also valid. In the directory that you uncompressed the source in, you will only have an src/ directory. 1. Pick a system to build for, and note its default AFS sys_name. A directory will be automatically created for binaries to be written into with this name when you build. alpha_dux40, alpha_dux50, alpha_dux51 alpha_linux22, alpha_linux24, alpha_linux26 alpha_nbsd15, alpha_nbsd16 amd64_fbsd_53 (client does not work) amd64_linux24, amd64_linux26 amd64_nbsd20, amd64_nbsd30, amd64_nbsd40 arm_linux24, arm_linux26 hp_ux11i, hp_ux110, hp_ux1123 (See notes below for information on getting missing header) hp_ux102 (Client port possible, but db servers and utilities work) i386_fbsd_50, i386_fbsd_51, i386_fbsd_52, i386_fbsd_53, i386_fbsd_60, i386_fbsd_61, i386_fbsd_62, i386_fbsd_70, i386_fbsd_80, i386_fbsd_81, i386_fbsd_90, amd64_fbsd_50, amd64_fbsd_51, amd64_fbsd_52, amd64_fbsd_53, amd64_fbsd_60, amd64_fbsd_61, amd64_fbsd_62, amd64_fbsd_70, amd64_fbsd_80, amd64_fbsd_81, amd64_fbsd_90 (client may work on 70 and later) i386_linux22, i386_linux24, i386_linux26 i386_nbsd15, i386_nbsd16, i386_nbsd20, i386_nbsd21, i386_nbsd30, i386_nbsd40 i386_obsd31, i386_obsd32, i386_obsd33, i386_obsd34, i386_obsd35, i386_obsd36, i386_obsd37, i386_obsd38, i386_obsd39, i386_obsd40, i386_obsd41 i386_umlinux22, i386_umlinux24, i386_umlinux26 ia64_hpux1122, ia64_hpux1123 ia64_linux24, ia64_linux26 parisc_linux24 ppc64_linux24, ppc64_linux26 ppc_darwin_12, ppc_darwin_13, ppc_darwin_14, ppc_darwin_60, ppc_darwin_70, ppc_darwin_80, ppc_darwin_90 ppc_linux22, ppc_linux24, ppc_linux26 ppc_nbsd16, ppc_nbsd20 rs_aix42, rs_aix51, rs_aix52, rs_aix53, rs_aix61 s390_linux22, s390_linux24, s390_linux26 s390x_linux24, s390x_linux26 sgi_62, sgi_63, sgi_64, sgi_65 (file server not tested) sparc64_linux22, sparc64_linux24, sparc64_linux26 sparc_linux22, sparc_linux24 sun4_413 (No client support, no fileserver support, db servers only) sun4x_56, sun4x_57, sun4x_58, sun4x_59, sun4x_510, sun4x_511 (logging UFS not supported for mixed-use partitions containing client cache) sunx86_57, sunx86_58, sunx86_59, sunx86_510, sunx86_511 (logging UFS not supported for mixed-use partitions containing client cache) x86_darwin_80, x86_darwin90 2. Using configure in the top level directory, configure for your AFS system type, providing the necessary flags: % ./configure --with-afs-sysname=sun4x_58 --enable-transarc-paths If you do not have the "configure" script, or if you modify the source files, you can re-create it by running regen.sh. You will need autoconf to do this. For some systems you need also provide the path in which your kernel headers for your configured kernel can be found. See the system-specific Notes sections below for details. If you want to build only the user-space programs and servers and not the kernel module, specify the --disable-kernel-module option on the ./configure command line. All binaries, except for the 'fileserver' and 'volserver' executables, are stripped of their symbol table information by default. To enable a debugging build, specify the --enable-debug option on the ./configure command line. This builds with debugging compiler options and disables stripping of binaries. You can also use different combinations of --enable-debug and --enable (or --disable)-strip-binaries for finer control. One can, for example, compile binaries for debug and strip them anyway. Alternatively, one can compile without debug and force the binaries to not be stripped. Note that these combinations are not necessarily useful. The two binaries noted above, 'fileserver' and 'volserver' will never be stripped, regardless of any options given to configure. There are two modes for directory path handling: "Transarc mode" and "default mode": - In Transarc mode, we retain compatibility with Transarc/IBM AFS tools by putting client configuaration files in /usr/vice/etc, and server files in /usr/afs under the traditional directory layout. - In default mode, files are located in standardized locations, usually under $(prefix). - Client programs, libraries, and related files always go in standard directories under $(prefix). This rule covers things that would go into $(bindir), $(includedir), $(libdir), $(mandir), and $(sbindir). - Other files get located in the following places: Directory Transarc Mode Default Mode ============ ========================= ============================== viceetcdir /usr/vice/etc $(sysconfdir)/openafs afssrvdir /usr/afs/bin (servers) $(libexecdir)/openafs afsconfdir /usr/afs/etc $(sysconfdir)/openafs/server afslocaldir /usr/afs/local $(localstatedir)/openafs afsdbdir /usr/afs/db $(localstatedir)/openafs/db afslogdir /usr/afs/logs $(localstatedir)/openafs/logs afsbosconfig $(afslocaldir)/BosConfig $(afsconfdir)/BosConfig afsbosserver $(afsbindir)/bosserver $(sbindir)/bosserver The Demand Attach Fileserver (DAFS), is built by providing the --enable-demand-attach-fs argument to configure. Note that the bosserver must be built with DAFS in order to be able to create the dafs instance, which will be used in place of the fs instance. In addition, the fileserver, volserver, salvager, salvage, and salvageserver binaries must be built for DAFS. For additional options, see section H below. B Building 1. Now, you can build OpenAFS. % make 2. Install your build using either "make install" to install into the current system (you will need to be root, and files will be placed as appropriate for Transarc or standard paths), "make install DESTDIR=/some/path" to install into an alternate directory tree, or if you configured with --enable-transarc-paths make dest to create a complete binary tree in the dest directory under the directory named for the sys_name you built for, e.g. sun4x_57/dest or i386_linux22/dest 2. As appropriate you can clean up or, if you're using Linux, build for another kernel version. To clean up: % make clean C Problems If you have a problem building this source, you may want to visit http://www.openafs.org/ to see if any problems have been reported or to find out how to get more help. Mailing lists have been set up to help; More details can be found on the openafs.org site. D Linux Notes For Linux systems you need also provide the path in which your kernel headers for your configured kernel can be found. This should be the path of the directory containing a child directory named "include". So if your version file was /usr/src/linux/include/linux/version.h you would invoke: % ./configure --with-afs-sysname=i386_linux24 \ --with-linux-kernel-headers=/usr/src/linux Currently you can build for only one Linux kernel at a time, and the version is extracted from the kernel headers in the root you specify. To build for another Linux kernel version: the system type defined in step A1. % ./configure --with-afs-sysname=i386_linux24 \ --with-linux-kernel-headers=/usr/src/linux-2.2.19-i686 % make Your dest tree will now include an additional kernel module for your additional kernel headers. Be aware that if the kernel version string which UTS_RELEASE is defined to in include/linux/version.h matches the last kernel you built for, the previous kernel module will be overwritten. E HP-UX 11.0 Notes HP-UX 11.0 requires a header called vfs_vm.h which HP has provided on their web site. Go to http://www.hp.com/dspp, choose Software downloads from the side menu, and select Software: HP operating systems and then Operating systems: HP-UX from the select boxes. The last select box will have an option for downloading vfs_vm.h. F OpenBSD Notes If you need to run regen.sh to make the configure script, you should first install autoconf-2.59, then setenv AUTOCONF_VERSION 2.59. You need kernel source installed to build OpenAFS. Use the --with-bsd-kernel-headers= configure option if your kernel source is not in /usr/src/sys. If you want to build src/aklog, add the following options to your configure. Note that you shouldn't need aklog because heimdal afslog does (almost) the same thing. --with-krb5 KRB5CFLAGS=-I/usr/include/kerberosV KRB5LIBS=-lcrypto src/packaging/OpenBSD/buildpkg.sh will make a tar file for installing the client. There is no server package, but I am told that "make install" will put server binaries in /usr/afs. Your kernel may panic when you try to shutdown after running the OpenAFS client. To prevent this, change the "dangling vnode" panic in sys/kern/vfs_syscalls.c to a printf and build a new kernel. You can't run arla and OpenAFS at the same time. G FreeBSD Notes The FreeBSD client may now work; It is tested on 7.0 and on current as of the commit date. You need kernel source installed to build OpenAFS. Use the --with-bsd-kernel-headers= configure option if your kernel source is not in /usr/src/sys. You also need access to your kernel build directory for the opt_global.h include file. Use the --with-bsd-kernel-build= configure option if your kernel build is not GENERIC in the standard place. If /usr/src/sys/${CPUARCH}/compile/GENERIC does not point to /usr/obj/usr/src/sys/GENERIC you may need to resolve that and retry the build. There is no server package, but I am told that "make install" will put server binaries in /usr/afs. You can't run arla and OpenAFS at the same time. H AIX notes Make sure that your default build environment is 32bit, ie. the OBJECT_MODE environment variable is either unset or set to "32". Verify this before doing configure and make. For example, assuming ksh/bash: export OBJECT_MODE=32 To build aklog (in order to be able to get tokens from your KRB5 ticket) you have to supply --with-krb5 to configure, the following example is for building on AIX 6.1 with the IBM Kerberos5 (krb5.client.rte and krb5.toolkit.adt on the Expansion Pack): ./configure --with-afs-sysname=rs_aix61 --enable-transarc-paths \ --enable-supergroups \ --with-krb5 KRB5CFLAGS=-I/usr/include KRB5LIBS=-lkrb5 I Other configure options AFS has a ton of other optional features that must be enabled using configure options. Here is a summary: --enable-bitmap-later Speeds the startup of the fileserver by deferring reading volume bitmaps until necessary. Demand attach is a better solution to the same problem. --enable-bos-new-config A bosserver built with this option will look for BosConfig.new when it restarts and, if present, replace BosConfig with that file before reading its configuration. --enable-bos-restricted-mode Enables support for restricted mode in the bosserver. This mode can be enabled or disabled via a command-line switch and a signal and can be enabled (but not disabled) remotely. When enabled, bosserver will not permit any operations that change the local file system (install, uninstall, prune), run commands on the server (exec, create, delete), or view files (getlog). --enable-demand-attach-fs Enable Demand Attach file servers. Demand Attach is an extensive re-engineering of the file server that avoids the long startup and shutdown delays of the traditional file server by enabling persistance of file server state to disk. It is still very new, but is expected to become the default in a future version of OpenAFS. --enable-disconnected Enable disconnected support in the cache manager (EXPERIMENTAL). --enable-fast-restart When restarting the fileserver, don't salvage volumes. Instead, assume all volumes are okay and only take them off-line if that assumption is incorrect. Using this option safely requires scanning the fileserver log for error messages when volumes are taken off-line and salvaging them manually. Not recommended; use demand attach instead. --enable-icmp-pmtu-discovery Enable path MTU discovery in the Rx libraries by decoding ICMP unreachable packets. --enable-namei-fileserver Forces the namei fileserver on platforms (like Solaris) where the inode fileserver is the default. --enable-pthreaded-ubik Enable the threaded version of Ubik and install the threaded versions of Ubik servers. See README.PTHREADED_UBIK for more information. (EXPERIMENTAL) --enable-supergroups Enables support of nested groups in the ptserver. WARNING: Once you make use of this option by nesting one group inside another, the resulting PTS database cannot be correctly and safely used by a ptserver built without this option. --enable-tivoli-tsm Build with the Tivoli TSM API libraries for butc support of the Tivoli backup system. --enable-unix-sockets Enable use of UNIX domain sockets for fssync. It's also possible to disable some standard features. None of these options are recommended but may be useful in unusual circumstances: --disable-afsdb Disable AFSDB DNS record support in the cache manager, normally used to find cell VLDB servers. --disable-full-vos-listvol-switch Removes support for the -format option to vos listvol and also suppresses some additional fields that were added to vos examine output but may confuse older software. --disable-largefile-fileserver Disable large file (>2GB) support in the fileserver. --disable-pam Do not build the AFS PAM modules. Normally building them is harmless, but the PAM modules that come with OpenAFS are deprecated and should not be used unless you're still using the OpenAFS kaserver (which is itself deprecated and should not be used).
