       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-1.7.2

       If your /tmp is mounted with the option noexec (RHEL seems to do 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 https://oss.oetiker.ch/rrdtool/pub/rrdtool-1.7.2.tar.gz
        gunzip -c rrdtool-1.7.2.tar.gz | tar xf -
        cd rrdtool-1.7.2
        ./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 $BUILD_DIR
        wget https://oss.oetiker.ch/rrdtool/pub/libs/zlib-1.2.3.tar.gz
        gunzip -c zlib-1.2.3.tar.gz | tar xf -
        cd zlib-1.2.3
        ./configure --prefix=$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 lines means that the command is split
       over multiple lines.

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

       Building freetype

        cd $BUILD_DIR
        wget https://oss.oetiker.ch/rrdtool/pub/libs/freetype-2.3.5.tar.gz
        gunzip -c freetype-2.3.5.tar.gz | tar xf -
        cd freetype-2.3.5
        ./configure --prefix=$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 $BUILD_DIR
        wget https://oss.oetiker.ch/rrdtool/pub/libs/libxml2-2.6.32.tar.gz
        gunzip -c libxml2-2.6.32.tar.gz | tar xf -
        cd libxml2-2.6.32
        ./configure --prefix=$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 $BUILD_DIR
        wget https://oss.oetiker.ch/rrdtool/pub/libs/fontconfig-2.4.2.tar.gz
        gunzip -c fontconfig-2.4.2.tar.gz   | tar xf -
        cd fontconfig-2.4.2
        ./configure --prefix=$INSTALL_DIR CFLAGS="-O3 -fPIC" --with-freetype-config=$INSTALL_DIR/bin/freetype-config
        $MAKE
        $MAKE install

       Building Pixman

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

       Building Cairo

        cd $BUILD_DIR
        wget https://oss.oetiker.ch/rrdtool/pub/libs/cairo-1.6.4.tar.gz
        gunzip -c cairo-1.6.4.tar.gz   | tar xf -
        cd cairo-1.6.4
        ./configure --prefix=$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 to do

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

       Building Glib

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

       Building Pango

        cd $BUILD_DIR
        wget https://oss.oetiker.ch/rrdtool/pub/libs/pango-1.21.1.tar.bz2
        bunzip2 -c pango-1.21.1.tar.bz2 | tar xf -
        cd pango-1.21.1
        ./configure --prefix=$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 $BUILD_DIR/rrdtool-1.7.2
        ./configure --prefix=$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.
