3 rrdbuild - Instructions for building RRDtool
5 =head1 DESCRIPTION
7 =head2 Overview
9 If you downloaded the source of rrdtool you have to compile it. This
10 document will give some information on how this is done.
12 RRDtool relies on services of thrid part libraries. Some of these libraries
13 may already be installed on your system. You have to compile copies of the other
14 ones before you can build RRDtool.
16 This document will tell you about all the necessary steps to get going.
18 =head2 Building
20 Before you start to build RRDtool, you have to decide two things:
22 =over
24 =item 1.
26 In which directory you want to build the software.
28 =item 2.
30 Where you want to install the software.
32 =back
34 Once you have decided. Save the two locations into environment variables.
35 Depending on the shell you are using, you can do either (bash,zsh):
37 BUILD_DIR=/tmp/rrdbuild
38 INSTALL_DIR=/usr/local/rrdtool-1.2.8
40 Or if you run tcsh:
42 set BUILD_DIR=/tmp/rrdbuild
43 set INSTALL_DIR=/usr/local/rrdtool-1.2.8
45 Now make sure the BUILD_DIR exists and go there:
47 mkdir -p $BUILD_DIR
48 cd $BUILD_DIR
50 Lets first assume you already have all the necessary libraries
51 per-installed. Note that these instructions assume that your copies of
52 B<tar> and B<make> are actually B<GNU tar> and B<GNU make> respectively. It
53 could be that they are installed as B<gtar> and B<gmake> on your system.
55 wget http://people.ee.ethz.ch/oetiker/webtools/rrdtool/pub/rrdtool-1.2.8.tar.gz
56 tar zxf rrdtool-1.2.8.tar.gz
57 cd rrdtool-1.2.8
58 ./configure --prefix=/path/to/installation && make && make install
60 Ok, this was very optimistic. This try will probably have ended with
61 B<configure> complaining about several missing libraries. If you are on a
62 Linux or *bsd system you may want to just install the missing bits from your
63 software repository. When you do that, make sure you also get the B<-dev>
64 package for each library you install. Once you have the missing bits on
65 board, just re-run the last line of the instructions above.
67 But again this may have been too optimistic, and you actually have to
68 compile your own copies of the required libraries. Here is how:
70 =over
72 =item Building cgilib
74 cd $BUILD_DIR
75 wget http://people.ee.ethz.ch/oetiker/webtools/rrdtool/pub/libs/cgilib-0.5.tar.gz
76 tar zxf cgilib-0.5.tar.gz
77 cd cgilib-0.5
78 make CC=gcc CFLAGS="-O3 -fPIC -I."
79 mkdir -p $BUILD_DIR/lb/include
80 cp *.h $BUILD_DIR/lb/include
81 mkdir -p $BUILD_DIR/lb/lib
82 cp libcgi* $BUILD_DIR/lb/lib
84 =item Building zlib
86 cd $BUILD_DIR
87 wget http://people.ee.ethz.ch/oetiker/webtools/rrdtool/pub/libs/zlib-1.2.2.tar.gz
88 tar zxf zlib-1.2.2.tar.gz
89 cd zlib-1.2.2
90 env CFLAGS="-O3 -fPIC" ./configure --prefix=$BUILD_DIR/lb
91 make
92 make install
94 =item Building libpng
96 Libpng itself requires zlib to build, so we need to help a bit. If you
97 already have a copy of zlib on your system (which is very likley) you can
98 drop the settings of LDFLAGS and CPPFLAGS. Note that the backslash (\) at
99 the end of line 4 means that line 4 and line 5 are on one line.
101 cd $BUILD_DIR
102 wget http://people.ee.ethz.ch/oetiker/webtools/rrdtool/pub/libs/libpng-1.2.8-config.tar.gz
103 tar zxvf libpng-1.2.8-config.tar.gz
104 cd libpng-1.2.8-config
105 env CPPFLAGS="-I$BUILD_DIR/lb/include" LDFLAGS="-L$BUILD_DIR/lb/lib" CFLAGS="-O3 -fPIC" \
106 ./configure --disable-shared --prefix=$BUILD_DIR/lb
107 make
108 make install
110 =item Building freetype
112 cd $BUILD_DIR
113 wget http://people.ee.ethz.ch/oetiker/webtools/rrdtool/pub/libs/freetype-2.1.9.tar.gz
114 tar zxvf freetype-2.1.9.tar.gz
115 cd freetype-2.1.9
116 env CPPFLAGS="-I$BUILD_DIR/lb/include" LDFLAGS="-L$BUILD_DIR/lb/lib" CFLAGS="-O3 -fPIC" \
117 ./configure --disable-shared --prefix=$BUILD_DIR/lb
118 make
119 make install
122 =item Building libart_lgpl
124 cd $BUILD_DIR
125 wget http://people.ee.ethz.ch/oetiker/webtools/rrdtool/pub/libs/libart_lgpl-2.3.17.tar.gz
126 cd libart_lgpl-2.3.17
127 env CFLAGS="-O3 -fPIC" ./configure --disable-shared --prefix=$BUILD_DIR/lb
128 make
129 make install
131 =back
133 Now all the dependent libraries are built and you can try again. This time
134 you tell configure where it should be looking for libraries and include
135 files. This is done via environment variables. Depending on the shellyou are running, the syntax for setting
136 environment variables is different. Under csh/tcsh you use:
138 set IR=-I$BUILD_DIR/lb/include
139 setenv CPPFLAGS "$IR $IR/libart-2.0 $IR/freetype2 $IR/libpng"
140 setenv LDFLAGS -L$BUILD_DIR/lb/lib
141 setenv CFLAGS -O3
143 If you are running bash/sh/ash/ksh/zsh use this:
145 IR=-I$BUILD_DIR/lb/include
146 CPPFLAGS="$IR $IR/libart-2.0 $IR/freetype2 $IR/libpng"
147 LDFLAGS="-L$BUILD_DIR/lb/lib"
148 CFLAGS=-O3
149 export CPPFLAGS LDFLAGS CFLAGS
151 And finally try building again:
153 ./configure --prefix=$INSTALL_DIR && make && make install
155 Now go to I<$INSTALL_DIR>B</examples> and run them to see if your
156 build has been successful.
