To prevent stripping, specify the '--disable-strip-binaries' option on
the ./configure command line. fileserver and volserver are never stripped.

When --enable-debug is specified, binaries will not be stripped by default.

Short instructions for sites upgrading from a previous version of AFS:
% ./configure --enable-transarc-paths
% make
% make dest
will create a Transarc-style dest tree in ${SYS_NAME}/dest where
${SYS_NAME} is the AFS sysname of the system you built for.
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. Creating the proper directory structure.
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.

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 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.
There is an option to control whether or not binaries are stripped
of their symbol table information. All binaries, except for the
'fileserver' and 'volserver' executables, are stripped by default.
To prevent stripping, specify the '--disable-strip-binaries' option on
the ./configure command line.
This option works alongside the existing --enable-debug option to
control how binaries are produced. When --enable-debug is specified,
binaries will not be stripped. This behavior can be modified by
using different combinations of --enable-debug and --enable (or
--disable)-strip-binaries. 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.
If neither of these options is specified, the default will be to build
non-debug binaries that are stripped (with the exceptions noted above,
which are never stripped at present). Specifying --enable-debug also
turns on --disable-strip-binaries. These are the most useful settings.
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

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: http://h21007.www2.hp.com/dspp/tech/tech_TechSoftwareDetailPage_IDX/1,1703,687,00.html
To navigate down from the top level of the portal, one would do
www.hp.com/dspp -> i want to... -> download software -> operating systems
to get to the same page.
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 does not currently work. The remaining problems
mostly have to do with locking, vnode refcounting, and packaging. The
server should work.
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.
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.
