rrdbuild - Instructions for building RRDtool

OVERVIEW

If you downloaded the source of RRDtool you have to compile it. This document will give
some information on how this is done.

RRDtool relies on services of third part libraries. Some of these libraries may already be
installed on your system. You have to compile copies of the other ones before you can
build RRDtool.

This document will tell you about all the necessary steps to get going.

These instructions assume you are using a bash shell. If you use csh/tcsh, then you can
either type bash to switch to bash for the compilation or if you know what you are doing
just replace the export bits with setenv.

We further assume that your copies of tar and make are actually GNU tar and GNU make
respectively. It could be that they are installed as gtar and gmake on your system.

OPTIMISTIC BUILD

Before you start to build RRDtool, you have to decide two things:

1. In which directory you want to build the software.

2. Where you want to install the software.

Once you have decided. Save the two locations into environment variables.

BUILD_DIR=/tmp/rrdbuild
INSTALL_DIR=/opt/rrdtool-1.5.4

If your /tmp is mounted with the option noexec (RHEL seems todo that) you have to choose a
different directory!

Now make sure the BUILD_DIR exists and go there:

mkdir -p $BUILD_DIR
cd $BUILD_DIR

Lets first assume you already have all the necessary libraries pre-installed.

wget http://oss.oetiker.ch/rrdtool/pub/rrdtool-1.5.4.tar.gz
gunzip -c rrdtool-1.5.4.tar.gz | tar xf -
cd rrdtool-1.5.4
./configure --prefix=$INSTALL_DIR && make && make install

Ok, this was very optimistic. This try will probably have ended with configure complaining
about several missing libraries.

INSTALLING DEPENDENCIES

If your OS lets you install additional packages from a software repository, you may get
away with installing the missing packages. When the packages are installed, run configure
again and try to compile again. Below you find some hints on getting your OS ready for
compiling RRDtool.

Additions to this list are welcome. In general RRDtool should work with the latest
versions of the libraries. The versions listed here are just what was current when I
tested this.

OpenSolaris 2008.05
Just add a compiler and the gnome development package:

pkg install sunstudioexpress
pkg install SUNWgnome-common-devel

There is a problem with cairo.pc on OpenSolaris. It suggests that xrender is required for
compilation with cairo. This is not true and also bad since OpenSolaris does not include
an xrender.pc file. Use Perl to fix this:

perl -i~ -p -e 's/(Requires.*?)\s*xrender.*/$1/' /usr/lib/pkgconfig/cairo.pc

Make sure the RRDtool build system finds your new compiler

export PATH=/opt/SunStudioExpress/bin

Debian / Ubuntu
Use apt-get to make sure you have all that is required. A number of packages will get
added through dependencies.

apt-get install libpango1.0-dev libxml2-dev

Gentoo
In Gentoo installing RRDtool is really simple you just need to emerge rrdtool. All
dependencies will be handled automatically by the portage system. The only thing you
should care about are USE flags, which allow you fine tune features RRDtool will be built
with. Currently the following USE flags are available:

doc - install .html and .txt documentation
into /usr/share/doc/rrdtool-1.x.xx/
perl - build and install perl language bindings
python - build and install python language bindings
ruby - build and install ruby language bindings
tcl - build and install tcl language bindings
rrdcgi - build and install rrdcgi

After you've decided which USE flags you need, set them either in make.conf or
/etc/portage/package.use and finally run:

# emerge -va rrdtool

Take a look at Gentoo handbook for further details on how to manage USE flags:
http://www.gentoo.org/doc/en/handbook/handbook-x86.xml?part=2

BUILDING DEPENDENCIES

But again this may have been too optimistic still, and you actually have to compile your
own copies of some of the required libraries. Things like libpng and zlib are pretty
standard so you will probably have them on your system anyway. Freetype, Fontinst, Cairo,
Pango may be installed, but it is possible that they are pretty old and thus don't live up
to our expectations, so you may want to compile their latest versions.

General build tips for AIX
If you are working with AIX, you may find the --disable-shared option will cause things to
break for you. In that case you may have to install the shared libraries into the RRDtool
PREFIX and work with --disable-static instead.

Another hint to get RRDtool working on AIX is to use the IBM XL C Compiler:

export CC=/usr/vac/bin/cc
export PERLCC=$CC

(Better instructions for AIX welcome!)

Build Instructions
Some libraries want to know where other libraries are. For this to work, set the following
environment variable

export PKG_CONFIG_PATH=${INSTALL_DIR}/lib/pkgconfig
export PATH=$INSTALL_DIR/bin:$PATH

The above relies on the presence of the pkgconfig program. Below you find instructions on
how to compile pkgconfig.

Since we are compiling libraries dynamically, they must know where to find each other.
This is done by setting an appropriate LDFLAGS. Unfortunately, the syntax again differs
from system to system:

Solaris
export LDFLAGS=-R${INSTALL_DIR}/lib

if you are using the Sun Studio/Forte compiler, you may also want to set

CFLAGS="-xO3 -xcode=pic13" (SPARC)
CFLAGS="-xO3 -Kpic" (x86)

Linux
export LDFLAGS="-Wl,--rpath -Wl,${INSTALL_DIR}/lib"

HPUX
export LDFLAGS="+b${INSTALL_DIR}/lib"

AIX
export LDFLAGS="-Wl,-blibpath:${INSTALL_DIR}/lib"

If you have GNU make installed and it is not called 'make', then do

export MAKE=gmake
export GNUMAKE=gmake

otherwise just do

export MAKE=make

Building pkgconfig

As mentioned above, without pkgconfig the whole build process will be lots of pain and
suffering, so make sure you have a copy on your system. If it is not available natively,
here is how to compile it.

wget http://pkgconfig.freedesktop.org/releases/pkg-config-0.23.tar.gz
gunzip -c pkg-config-0.23.tar.gz | tar xf -
cd pkg-config-0.23
./configure --prefix=$INSTALL_DIR CFLAGS="-O3 -fPIC"
$MAKE
$MAKE install

After installing pkgconfig in a custom directory, setting up the corresponding environment
variable will be helpful.

export PKG_CONFIG=$INSTALL_DIR/bin/pkg-config

Building zlib

Chances are very high that you already have that on your system ...

cd $BUILD_DIR
wget http://oss.oetiker.ch/rrdtool/pub/libs/zlib-1.2.3.tar.gz
gunzip -c zlib-1.2.3.tar.gz | tar xf -
cd zlib-1.2.3
./configure --prefix=$INSTALL_DIR CFLAGS="-O3 -fPIC" --shared
$MAKE
$MAKE install

Building libpng

Libpng itself requires zlib to build, so we need to help a bit. If you already have a copy
of zlib on your system (which is very likely) you can drop the settings of LDFLAGS and
CPPFLAGS. Note that the backslash (\) at the end of line 4 means that line 4 and line 5
are on one line.

cd $BUILD_DIR
wget http://oss.oetiker.ch/rrdtool/pub/libs/libpng-1.2.18.tar.gz
gunzip -c libpng-1.2.18.tar.gz | tar xf -
cd libpng-1.2.18
env CFLAGS="-O3 -fPIC" ./configure --prefix=$INSTALL_DIR
$MAKE
$MAKE install

Building freetype

cd $BUILD_DIR
wget http://oss.oetiker.ch/rrdtool/pub/libs/freetype-2.3.5.tar.gz
gunzip -c freetype-2.3.5.tar.gz | tar xf -
cd freetype-2.3.5
./configure --prefix=$INSTALL_DIR CFLAGS="-O3 -fPIC"
$MAKE
$MAKE install

If you run into problems building freetype on Solaris, you may want to try to add the
following at the start the configure line:

env EGREP=egrep

Building LibXML2

cd $BUILD_DIR
wget http://oss.oetiker.ch/rrdtool/pub/libs/libxml2-2.6.32.tar.gz
gunzip -c libxml2-2.6.32.tar.gz | tar xf -
cd libxml2-2.6.32
./configure --prefix=$INSTALL_DIR CFLAGS="-O3 -fPIC"
$MAKE
$MAKE install

Building fontconfig

Note that fontconfig has a run time configuration file in INSTALL_DIR/etc you may want to
adjust that so that fontconfig finds the fonts on your system. Run the fc-cache program
to build the fontconfig cache after changing the config file.

cd $BUILD_DIR
wget http://oss.oetiker.ch/rrdtool/pub/libs/fontconfig-2.4.2.tar.gz
gunzip -c fontconfig-2.4.2.tar.gz | tar xf -
cd fontconfig-2.4.2
./configure --prefix=$INSTALL_DIR CFLAGS="-O3 -fPIC" --with-freetype-config=$INSTALL_DIR/bin/freetype-config
$MAKE
$MAKE install

Building Pixman

cd $BUILD_DIR
wget http://oss.oetiker.ch/rrdtool/pub/libs/pixman-0.10.0.tar.gz
gunzip -c pixman-0.10.0.tar.gz | tar xf -
cd pixman-0.10.0
./configure --prefix=$INSTALL_DIR CFLAGS="-O3 -fPIC"
$MAKE
$MAKE install

Building Cairo

cd $BUILD_DIR
wget http://oss.oetiker.ch/rrdtool/pub/libs/cairo-1.6.4.tar.gz
gunzip -c cairo-1.6.4.tar.gz | tar xf -
cd cairo-1.6.4
./configure --prefix=$INSTALL_DIR \
--enable-xlib=no \
--enable-xlib-render=no \
--enable-win32=no \
CFLAGS="-O3 -fPIC"
$MAKE
$MAKE install

When building on Solaris you may want todo

./configure --prefix=$INSTALL_DIR \
--enable-xlib=no \
--enable-xlib-render=no \
--enable-win32=no \
CFLAGS="-O3 -fPIC -D_POSIX_PTHREAD_SEMANTICS"

Building Glib

cd $BUILD_DIR
wget http://oss.oetiker.ch/rrdtool/pub/libs/glib-2.15.4.tar.gz
gunzip -c glib-2.15.4.tar.gz | tar xf -
cd glib-2.15.4
./configure --prefix=$INSTALL_DIR CFLAGS="-O3 -fPIC"
$MAKE
$MAKE install

Building Pango

cd $BUILD_DIR
wget http://oss.oetiker.ch/rrdtool/pub/libs/pango-1.21.1.tar.bz2
bunzip2 -c pango-1.21.1.tar.bz2 | tar xf -
cd pango-1.21.1
./configure --prefix=$INSTALL_DIR CFLAGS="-O3 -fPIC" --without-x
$MAKE
$MAKE install

Building rrdtool (second try)
Now all the dependent libraries are built and you can try again. This time you tell
configure where it should be looking for libraries and include files. This is done via
environment variables. Depending on the shell you are running, the syntax for setting
environment variables is different.

And finally try building again. We disable the python and tcl bindings because it seems
that a fair number of people have ill configured python and tcl setups that would prevent
RRDtool from building if they are included in their current state.

cd $BUILD_DIR/rrdtool-1.5.4
./configure --prefix=$INSTALL_DIR --disable-tcl --disable-python
$MAKE clean
$MAKE
$MAKE install

SOLARIS HINT: if you want to build the Perl module for the native Perl (the one shipping
with Solaris) you will need the Sun Forte compiler installed on your box or you have to
hand-tune bindings/perl-shared/Makefile while building!

Now go to $INSTALL_DIR/share/rrdtool/examples/ and run them to see if your build has been
successful.
