THIS IS HERE ONLY TO SUPPORT SYSTEMTAP DEVELOPMENT. IT IS NOT FOR GENERAL USE.
|
|
|
|
Building systemtap requires a recent development version of elfutils,
|
|
which provides libraries for making use of debugging information.
|
|
|
|
This is unfinished work in active development. This code is not intended
|
|
for general consumption in its present form. Development of these
|
|
libraries is simultaneous with Systemtap development. The Systemtap code
|
|
will require new versions as things evolve; the systemtap.spec.in file in
|
|
the systemtap source tree should always indicate the minimum version of
|
|
elfutils libraries that will suffice. We will make an effort to make a
|
|
compatible version available here, that you can use for compiling Systemtap.
|
|
|
|
Current elfutils can always be found in Fedora Core Development, AKA Rawhide.
|
|
If you are interested in the elfutils code in general or for any purpose
|
|
other than developing Systemtap, please see http://fedora.redhat.com/ about
|
|
getting involved with Fedora Core Development directly.
|
|
|
|
To use the elfutils libraries to build Systemtap, you can either use
|
|
installed libraries, or you can build elfutils from source as part of the
|
|
systemtap build. To use installed libraries, you'll need to have the
|
|
current elfutils version installed on your system where the compiler will
|
|
find it with whatever build flags you pass systemtap's configure script.
|
|
Unless your system already has the current elfutils installed
|
|
(i.e. Rawhide), you'll have to install a nonstandard build either via RPM
|
|
or by hand with "make" as detailed below. To build the elfutils source
|
|
locally as part of the systemtap build, see systemtap's README about the
|
|
--with-elfutils=... option to systemtap's configure.
|
|
|
|
You can find the rawhide rpms updated daily on a variety of sites
|
|
(see http://fedora.redhat.com/download/mirrors.html) under core/development.
|
|
What's distributed in this directory is made trivially from those same sources.
|
|
|
|
The vanilla elfutils code, in elfutils-VERSION.tar.gz and what the rawhide
|
|
RPMs ordinarily build, can only be built using GCC 4 and a recent glibc.
|
|
Fedora Core 4 is the only released system meeting the requirements.
|
|
|
|
To rebuild the rawhide src.rpm on an older system, you can use:
|
|
|
|
rpmbuild --with compat --rebuild elfutils-VERSION-N.src.rpm
|
|
|
|
The SRPMS/elfutils-VERSION-0.N.src.rpm provided here is exactly the same as
|
|
the elfutils-VERSION-N.src.rpm from Rawhide except that it doesn't require
|
|
that you specify --with compat to build on an older system.
|
|
|
|
We have done this for you for a few architectures, and those RPMs are
|
|
available here. These were built on RHEL3, and so their requirements
|
|
should not be too demanding. We must remind you that this is unsupported,
|
|
pre-beta development code. Furthermore, these builds are completely
|
|
unofficial, unsupported, unsigned, unlikely to have been tested,
|
|
unequivocally not guaranteed not to ruin your whole day, and we really
|
|
cannot recommend that anyone install them on their system. Do so at your
|
|
own risk. All that said, here they is, and if you copy this file:
|
|
|
|
ftp://sources.redhat.com/pub/systemtap/elfutils/systemtap-elfutils.repo
|
|
|
|
into your /etc/yum.repos.d/ directory, then you can get them all with just:
|
|
|
|
yum install elfutils-devel
|
|
|
|
|
|
To compile elfutils from source by hand, simply use elfutils-VERSION.tar.gz
|
|
and follow the usual procedure for GNU configure conventions. The patch
|
|
available here has to be applied before you can compile on an older system:
|
|
|
|
tar xzf elfutils-VERSION.tar.gz
|
|
patch -p1 -d elfutils-VERSION < elfutils-portability.patch
|
|
cd elfutils-VERSION
|
|
./configure --program-prefix=eu-devel-
|
|
make && make check && make install
|
|
|
|
(That of course installs things under /usr/local, unlike the RPMs.)
|
|
|
|
|
|
Caveat emptor. Carpe noctem.
