2 These are the installation instructions for release 1.0 of the Omega
3 Library, Omega Calculator, and Petit.
10 All files are available in the directory ftp://ftp.cs.umd.edu/pub/omega.
12 There are a number of different things you can make.
15 oc: The Omega Calculator. Text interface to the Omega library and the
16 code generation library.
17 DEMO: omega_calc_sparc_demo.tar.gz
18 SOURCE NEEDED: omega_calc.tar.gz, omega_library.tar.gz, code_gen.tar.gz
20 Petit: Our extended version of Michael Wolfe's Tiny tool. A research
21 tool for dependence analysis and program transformations.
22 DEMO: petit_sparc_demo.tar.gz
23 SOURCE NEEDED: petit.tar.gz, omega_library.tar.gz,
24 code_gen.tar.gz, uniform.tar.gz
28 libomega.a: The Omega library, contains relation operations and presburger
30 SOURCE NEEDED: omega_library.tar.gz
31 libcode_gen.a: Library for generating code to scan the solutions of a set.
32 SOURCE NEEDED: code_gen.tar.gz, omega_library.tar.gz
33 libuniform.a: The Uniform library, a source to source parallelizing
34 transformation system, described in Wayne Kelly's Ph.D. dissertation.
35 SOURCE NEEDED: uniform.tar.gz, omega_library.tar.gz, optionally petit
39 You should unpack all tar files in the same directory; they will unpack as:
41 omega/ Root of the Omega system, contains makefiles, information files.
42 omega_lib/ The Omega Library.
43 basic/ Data structures for the library; included in
44 the omega_library.tar file.
45 omega_calc/ The Omega Calculator.
46 petit/ The Petit tool.
47 code_gen/ Code generation library
48 uniform/ Uniform library
50 Each library or executable's directory will have subdirectories of
51 src/, include/, and obj/.
53 Users with code that uses previous versions of the Omega library may
54 need to make some changes to their code in order to comply with the new
55 functions for checking subsets, satisfiability, and tautologies.
63 C++ compiler: You will need a C++ compiler; G++ and SunPro CC
64 are currently the only ones known to work, but others may work
66 Make: If you have GNU Make (gmake), you should use it; other
67 makes may work, but may have trouble either with the include
68 syntax, or with the pattern-match rules in the Makefiles.
69 Motif: If you want to build petit, then you will need to have the
70 Motif libraries and include files. You can build a
71 command-line version by specifying -DBATCH_ONLY_PETIT in
73 Flex and Bison: flex and bison are required if you want to modify
74 the grammars, but not otherwise.
76 1. Edit omega/Makefile.config. This has a few things to edit,
77 such as location of system-specific files, and options for different
80 2. Do "make depend" in the omega directory.
82 3. Choose a target, and make it.
83 Targets are: oc, petit, libomega.a, and libcode_gen.a.
85 You can also change to the target's obj/ subdirectory, for example
86 omega/omega_calc/obj/, and do a "make" there.
88 4. You can use the items in place (they will be left in their respective
89 obj/ directories), move them someplace you want, or use the install
90 procedure in the INSTALLATION section.
98 You may run into trouble if your make does not support % rules or
99 the particular include syntax in our makefiles. The easiest
100 solution is to switch to GNU make (gmake). If that is not an
101 option, the first problem can be overcome by making symbolic links
102 to all ../src files from each obj/ directory. The second can be
103 overcome by editing each Makefile and Makefile.rules to change
104 the include syntax to one your make supports.
107 We are aware of the large number of warnings, which result from changes
108 made to the C++ language by the ANSI committee. The resulting object
109 files are correct. We're working on this problem and hope to address
110 it in a future release.
113 We haven't anticipated any other problems you might have, so for any
114 other problems you have, write to omega@cs.umd.edu.
121 If you want to install the library in a public directory, you need to
122 set a DESTDIR in Makefile.config. The files will be installed as:
124 DESTDIR/ Installation root
125 lib/ All library files go here (libomega.a, libcode_gen.a)
127 omega.h Main omega include file.
128 omega/ Omega library includes.
129 basic/ Basic includes.
130 code_gen/ Code generation includes.
131 bin/ Binaries (oc, petit)
133 You can change the relative layout of these files by editing the other
134 destination variables in Makefile.config.
139 DOCUMENTATION AND QUESTIONS
141 Documentation for the Omega calculator is in omega/omega_calc/doc;
142 Omega library are docs in omega/omega_lib/doc; documentation for petit
143 is in omega/petit/doc. There are also README files in the omega_calc/
144 and petit/ directories.

149 If you have any problems, questions, or comments about installation,
150 please send us email at omega@cs.umd.edu. We'd like to fix any
151 problems you run into for future releases.
