RRDBUILD(1)                         rrdtool                        RRDBUILD(1)



NAME
       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-1.4.7

       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-1.4.7.tar.gz
        gunzip -c rrdtool-1.4.7.tar.gz | tar xf -
        cd rrdtool-1.4.7
        ./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 $BUILD_DIR
        wget http://oss.oetiker.ch/rrdtool/pub/libs/libpng-1.2.18.tar.gz
        gunzip -c libpng-1.2.18.tar.gz | tar xf -
        cd libpng-1.2.10
        env CFLAGS="-O3 -fPIC" ./configure --prefix=$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 $BUILD_DIR/rrdtool-1.4.7
        ./configure --prefix=$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.
