Installation Instructions
2 2
=========================
3 3

	
4 4
Since you are reading this I assume you already obtained one of the release
5 5
tarballs and successfully extracted it. The latest version of LEMON is
6 6
available at our web page (http://lemon.cs.elte.hu/).
7 7

	
8 8
LEMON provides two different build environments, one is based on "autotool",
9 9
while the other is based on "cmake". This file contains instructions only for
10 10
the former one, which is the recommended build environment on Linux, Mac OSX
11 11
and other unices or if you use Cygwin on Windows. For cmake installation
12 12
instructions visit http://lemon.cs.elte.hu.
13 13

	
14 14
In order to install LEMON from the extracted source tarball you have to
15 15
issue the following commands:
16 16

	
17 17
   1. `cd lemon-x.y.z'
18 18

	
19 19
      This command changes to the directory which was created when you
20 20
      extracted the sources. The x.y.z part is a version number.
21 21

	
22 22
   2. `./configure'
23 23

	
24 24
      This command runs the configure shell script, which does some checks and
25 25
      creates the makefiles.
26 26

	
27 27
   3. `make'
28 28

	
29 29
      This command compiles the non-template part of LEMON into libemon.a
30 30
      file. It also compiles the programs in the tools subdirectory by
31 31
      default.
32 32

	
33 33
   4. `make check'
34 34

	
35 35
      This step is optional, but recommended. It runs the test programs that
36 36
      we developed for LEMON to check whether the library works properly on
37 37
      your platform.
38 38

	
39 39
   5. `make install'
40 40

	
41 41
      This command installs LEMON under /usr/local (you will need root
42 42
      privileges to be able to do that). If you want to install it to some
43 43
      other location, then pass the --prefix=DIRECTORY flag to configure in
44 44
      step 2. For example: `./configure --prefix=/home/username/lemon'.
45 45

	
46 46
   6. `make install-html'
47 47

	
48 48
      This command installs the documentation under share/doc/lemon/docs. The
49 49
      generated documentation is included in the tarball. If you want to
50 50
      generate it yourself, then run `make html'. Note that for this you need
51 51
      to have the following programs installed: Doxygen, Graphviz, Ghostscript,
52 52
      Latex.
53 53

	
54 54

	
55 55
Configure Options and Variables
56 56
===============================
57 57

	
58 58
In step 2 you can customize the actions of configure by setting variables
59 59
and passing options to it. This can be done like this:
60 60
`./configure [OPTION]... [VARIABLE=VALUE]...'
61 61

	
62 62
Below you will find some useful variables and options (see `./configure --help'
63 63
for more):
64 64

	
65 65
CXX='comp'
66 66

	
67 67
  Change the C++ compiler to 'comp'.
68 68

	
69 69
CXXFLAGS='flags'
70 70

	
71 71
  Pass the 'flags' to the compiler. For example CXXFLAGS='-O3 -march=pentium-m'
72 72
  turns on generation of aggressively optimized Pentium-M specific code.
73 73

	
74 74
--prefix=PREFIX
75 75

	
76 76
  Set the installation prefix to PREFIX. By default it is /usr/local.
77 77

	
78 78
--enable-tools
79 79

	
80 80
   Build the programs in the tools subdirectory (default).
81 81

	
82 82
--disable-tools
83 83

	
84 84
   Do not build the programs in the tools subdirectory.
85 85

	
86 86
--with-glpk[=PREFIX]
87 87

	
88 88
   Enable GLPK support (default). You should specify the prefix too if
89 89
   you installed GLPK to some non-standard location (e.g. your home
90 90
   directory). If it is not found, GLPK support will be disabled.
91 91

	
92 92
--with-glpk-includedir=DIR
93 93

	
94 94
   The directory where the GLPK header files are located. This is only
95 95
   useful when the GLPK headers and libraries are not under the same
96 96
   prefix (which is unlikely).
97 97

	
98 98
--with-glpk-libdir=DIR
99 99

	
100 100
   The directory where the GLPK libraries are located. This is only
101 101
   useful when the GLPK headers and libraries are not under the same
102 102
   prefix (which is unlikely).
103 103

	
104 104
--without-glpk
105 105

	
106 106
   Disable GLPK support.
107 107

	
108 108
--with-cplex[=PREFIX]
109 109

	
110 110
   Enable CPLEX support (default). You should specify the prefix too
111 111
   if you installed CPLEX to some non-standard location
112 112
   (e.g. /opt/ilog/cplex75). If it is not found, CPLEX support will be
113 113
   disabled.
114 114

	
115 115
--with-cplex-includedir=DIR
116 116

	
117 117
   The directory where the CPLEX header files are located. This is
118 118
   only useful when the CPLEX headers and libraries are not under the
119 119
   same prefix (e.g.  /usr/local/cplex/cplex75/include).
120 120

	
121 121
--with-cplex-libdir=DIR
122 122

	
123 123
   The directory where the CPLEX libraries are located. This is only
124 124
   useful when the CPLEX headers and libraries are not under the same
125 125
   prefix (e.g.
126 126
   /usr/local/cplex/cplex75/lib/i86_linux2_glibc2.2_gcc3.0/static_pic_mt).
127 127

	
128 128
--without-cplex
129 129

	
130 130
   Disable CPLEX support.
131 131

	
132 132
--with-soplex[=PREFIX]
133 133

	
134 134
   Enable SoPlex support (default). You should specify the prefix too if
135 135
   you installed SoPlex to some non-standard location (e.g. your home
136 136
   directory). If it is not found, SoPlex support will be disabled.
137 137

	
138 138
--with-soplex-includedir=DIR
139 139

	
140 140
   The directory where the SoPlex header files are located. This is only
141 141
   useful when the SoPlex headers and libraries are not under the same
142 142
   prefix (which is unlikely).
143 143

	
144 144
--with-soplex-libdir=DIR
145 145

	
146 146
   The directory where the SoPlex libraries are located. This is only
147 147
   useful when the SoPlex headers and libraries are not under the same
148 148
   prefix (which is unlikely).
149 149

	
150 150
--without-soplex
151 151

	
152 152
   Disable SoPlex support.
153

	
154
--with-coin[=PREFIX]
155

	
156
   Enable support for COIN-OR solvers (CLP and CBC). You should
157
   specify the prefix too. (by default, COIN-OR tools install
158
   themselves to the source code directory). This command enables the
159
   solvers that are actually found.
160

	
161
--with-coin-includedir=DIR
162

	
163
   The directory where the COIN-OR header files are located. This is
164
   only useful when the COIN-OR headers and libraries are not under
165
   the same prefix (which is unlikely).
166

	
167
--with-coin-libdir=DIR
168

	
169
   The directory where the COIN-OR libraries are located. This is only
170
   useful when the COIN-OR headers and libraries are not under the
171
   same prefix (which is unlikely).
172

	
173
--without-coin
174

	
175
   Disable COIN-OR support.
