rrdbuild − Instructions for building RRDtool

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.

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=/usr/local/rrdtool−1.3.8

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−1.3.8.tar.gz
 gunzip −c rrdtool−1.3.8.tar.gz | tar xf −
 cd rrdtool−1.3.8
 ./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.

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 the rrdtool compilation.

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 rrdtool finds your new compiler

 export PATH=/opt/SunStudioExpress/bin

Since there does not seem to be a viable msgfmt tool on OpenSolaris (short of installing it yourself). You have to call configure with the

 −−disable−libintl

option.

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

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

 export CFLAGS="−xO3 −xcode=pic13"   (SPARC)
 export CFLAGS="−xO3 −Kpic"          (x86)

Linux

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

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
 $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 −−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 $BUILD_DIR/rrdtool−1.3.8
 ./configure −−prefix=$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.
