NAME

rrdbuild - Instructions for building RRDtool

CONTENTS

DESCRIPTION

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 thrid 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.

Building

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. Depending on the shell you are using, you can do either (bash,zsh):



 BUILD_DIR=/tmp/rrdbuild
 INSTALL_DIR=/usr/local/rrdtool-1.2.30



Or if you run tcsh:



 set BUILD_DIR=/tmp/rrdbuild
 set INSTALL_DIR=/usr/local/rrdtool-1.2.30



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. Note that these instructions 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.



 wget http://oss.oetiker.ch/rrdtool/pub/rrdtool-1.2.30.tar.gz
 tar zxf rrdtool-1.2.30.tar.gz
 cd rrdtool-1.2.30
 ./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 you are on a Linux or *bsd system you may want to just install the missing bits from your software repository. When you do that, make sure you also get the -dev package for each library you install. Once you have the missing bits on board, just re-run the last line of the instructions above.

But again this may have been too optimistic, and you actually have to compile your own copies of the required libraries.

Build Tipps for AIX

If you are woking with AIX, you may find the 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!)

Building Libraries

In order to build the libraries you need a compiler on your system. Unfortunately compilers are not all alike. This has an effect on the CFLAGS you want to set. The examples below are for the popular GCC compiler suite. If you have an other compile you have to use the following settings:
Sun Forte on SPARC


 CFLAGS="-xO3 -xcode=pic13"



Sun Forte on x86


 CFLAGS="-xO3 -Kpic"



Building zlib


 cd $BUILD_DIR
 wget http://oss.oetiker.ch/rrdtool/pub/libs/zlib-1.2.3.tar.gz
 tar  zxf zlib-1.2.3.tar.gz
 cd zlib-1.2.3
 env CFLAGS="-O3 -fPIC" ./configure --prefix=$BUILD_DIR/lb
 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 likley) 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 $BUILD_DIR
 wget http://oss.oetiker.ch/rrdtool/pub/libs/libpng-1.2.10.tar.gz
 tar zxvf libpng-1.2.10.tar.gz
 cd libpng-1.2.10
 env CPPFLAGS="-I$BUILD_DIR/lb/include" LDFLAGS="-L$BUILD_DIR/lb/lib" CFLAGS="-O3 -fPIC" \
     ./configure --disable-shared --prefix=$BUILD_DIR/lb
 make
 make install



Building freetype


 cd $BUILD_DIR
 wget http://oss.oetiker.ch/rrdtool/pub/libs/freetype-2.1.10.tar.bz2
 tar jxvf freetype-2.1.10.tar.bz2
 cd freetype-2.1.10
 env CPPFLAGS="-I$BUILD_DIR/lb/include" LDFLAGS="-L$BUILD_DIR/lb/lib" CFLAGS="-O3 -fPIC" \
     ./configure --disable-shared --prefix=$BUILD_DIR/lb
 make
 make install



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



 GNUMAKE=gmake EGREP=egrep



Building libart_lgpl


 cd $BUILD_DIR
 wget http://oss.oetiker.ch/rrdtool/pub/libs/libart_lgpl-2.3.17.tar.gz
 tar zxvf libart_lgpl-2.3.17.tar.gz
 cd libart_lgpl-2.3.17
 env CFLAGS="-O3 -fPIC" ./configure --disable-shared --prefix=$BUILD_DIR/lb
 make
 make install



Now all the dependent libraries are built and you can try again. Since these are static libraries, you may have to use ranlib to make them accessible. Especially BSD systems like Mac OS X may require this, Linux and Solaris will do just fine without since their ar command does ranlibs job as well.



 ranlib $BUILD_DIR/lb/lib/*.a



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. Under csh/tcsh you use:



 set IR=-I$BUILD_DIR/lb/include
 setenv CPPFLAGS "$IR $IR/libart-2.0 $IR/freetype2 $IR/libpng"
 setenv LDFLAGS  -L$BUILD_DIR/lb/lib
 setenv CFLAGS -O3



If you are running bash/sh/ash/ksh/zsh use this:



 IR=-I$BUILD_DIR/lb/include
 CPPFLAGS="$IR $IR/libart-2.0 $IR/freetype2 $IR/libpng"
 LDFLAGS="-L$BUILD_DIR/lb/lib"
 CFLAGS=-O3
 export CPPFLAGS LDFLAGS CFLAGS



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 $BUILD_DIR/rrdtool-1.2.30
 ./configure --prefix=$INSTALL_DIR --disable-python --disable-tcl
 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.
