1 CVC4 prerelease version 1.7.
2 ============================
3
4 ## Supported Operating Systems
5
6 CVC4 can be built on Linux and macOS. For Windows, CVC4 can be cross-compiled
7 using Mingw-w64. We recommend a 64-bit operating system.
8
9 On macOS, we recommend using Homebrew (https://brew.sh/) to install the
10 dependencies. We also have a Homebrew Tap available at
11 https://github.com/CVC4/homebrew-cvc4 .
12
13 ## Build dependencies
14
15 The following tools and libraries are required to build and run CVC4.
16 Versions given are minimum versions; more recent versions should be
17 compatible.
18
19 - [GNU C and C++ (gcc and g++)](https://gcc.gnu.org)
20 or [Clang](https://clang.llvm.org) (reasonably recent versions)
21 - [CMake >= 3.1](https://cmake.org)
22 - [GNU Bash](https://www.gnu.org/software/bash/)
23 - [Python >= 2.7](https://www.python.org)
24 - [GMP v4.2 (GNU Multi-Precision arithmetic library)](https://gmplib.org)
25 - [libantlr3c v3.2 or v3.4 (ANTLR parser generator C support library)](http://www.antlr3.org/)
26
27 Some features, such as the theory of floating-point numbers, require
28 [optional dependencies](optional-dependencies) (see below).
29
30 ### Installing libantlr3c: ANTLR parser generator C support library
31
32 For libantlr3c, you can use the script contrib/get-antlr-3.4.
33 This will download, patch, and install libantlr3c.
34
35 If you're on a 32-bit machine, or if you have difficulty building
36 libantlr3c (or difficulty getting CVC4 to link against it), you
37 may need to remove the configure option `--enable-64bit` in the script.
38
39 ### Warning: GCC 4.5.1
40
41 GCC version 4.5.1 seems to have a bug in the optimizer that may result in
42 incorrect behavior (and wrong results) in many builds. This is a known problem
43 for MiniSat, and since MiniSat is at the core of CVC4, a problem for CVC4.
44 We recommend using a GCC version > 4.5.1.
45
46 ## Optional Dependencies
47
48 ### SymFPU (Support for the Theory of Floating Point Numbers)
49
50 [SymFPU](https://github.com/martin-cs/symfpu/tree/CVC4)
51 is an implementation of SMT-LIB/IEEE-754 floating-point operations in terms
52 of bit-vector operations.
53 It is required for supporting the theory of floating-point numbers and
54 can be installed using the `contrib/get-symfpu` script.
55 Configure CVC4 with `configure.sh --symfpu` to build with this dependency.
56
57 ### CaDiCaL (Optional SAT solver)
58
59 [CaDiCaL](https://github.com/arminbiere/cadical)
60 is a SAT solver that can be used for solving non-incremental bit-vector
61 problems with eager bit-blasting. This dependency may improve performance.
62 It can be installed using the `contrib/get-cadical script`.
63 Configure CVC4 with `configure.sh --cadical` to build with this dependency.
64
65 ### CryptoMiniSat (Optional SAT solver)
66
67 [CryptoMinisat](https://github.com/msoos/cryptominisat)
68 is a SAT solver that can be used for solving bit-vector problems with eager
69 bit-blasting. This dependency may improve performance.
70 It can be installed using the `contrib/get-cryptominisat` script.
71 Configure CVC4 with `configure.sh --cryptominisat` to build with this
72 dependency.
73
74 ### LFSC (The LFSC Proof Checker)
75
76 [LFSC](https://github.com/CVC4/LFSC) is required to check proofs internally
77 with --check-proofs. It can be installed using the `contrib/get-lfsc` script.
78 Configure CVC4 with `configure.sh --lfsc` to build with this dependency.
79
80 ### SWIG >= 3.0.x (Simplified Wrapper and Interface Generator)
81
82 SWIG 3.0.x (and a JDK) is necessary to build the Java API.
83 See [Language Bindings](language-bindings) below for build instructions.
84
85 ### CLN >= v1.3 (Class Library for Numbers)
86
87 [CLN](http://www.ginac.de/CLN)
88 is an alternative multiprecision arithmetic package that may offer better
89 performance and memory footprint than GMP.
90 Configure CVC4 with `configure.sh --cln` to build with this dependency.
91
92 Note that CLN is covered by the [GNU General Public License, version 3](https://www.gnu.org/licenses/gpl-3.0.en.html).
93 If you choose to use CVC4 with CLN support, you are licensing CVC4 under that
94 same license.
95 (Usually CVC4's license is more permissive than GPL, see the file `COPYING` in
96 the CVC4 source distribution for details.)
97
98 ### glpk-cut-log (A fork of the GNU Linear Programming Kit)
99
100 [glpk-cut-log](https://github.com/timothy-king/glpk-cut-log/) is a fork of
101 [GLPK](http://www.gnu.org/software/glpk/) (the GNU Linear Programming Kit).
102 This can be used to speed up certain classes of problems for the arithmetic
103 implementation in CVC4. (This is not recommended for most users.)
104
105 glpk-cut-log can be installed using the `contrib/get-glpk-cut-log` script.
106 Note that the only installation option is manual installation via this script.
107 CVC4 is no longer compatible with the main GLPK library.
108 Configure CVC4 with `configure.sh --glpk` to build with this dependency.
109
110 Note that GLPK and glpk-cut-log are covered by the [GNU General Public License, version 3](https://www.gnu.org/licenses/gpl-3.0.en.html).
111 If you choose to use CVC4 with GLPK support, you are licensing CVC4 under that
112 same license.
113 (Usually CVC4's license is more permissive; see above discussion.)
114
115 ### ABC library (Improved Bit-Vector Support)
116
117 [ABC](http://www.eecs.berkeley.edu/~alanmi/abc/) (A System for Sequential
118 Synthesis and Verification) is a library for synthesis and verification of
119 logic circuits. This dependency may improve performance of the eager
120 bit-vector solver. When enabled, the bit-blasted formula is encoded into
121 and-inverter-graphs (AIG) and ABC is used to simplify these AIGs.
122
123 ABC can be installed using the `contrib/get-abc` script.
124 Configure CVC4 with `configure.sh --abc` to build with this dependency.
125
126 ### GNU Readline library (Improved Interactive Experience)
127
128 The [GNU Readline](http://cnswww.cns.cwru.edu/php/chet/readline/rltop.html)
129 library is optionally used to provide command editing, tab completion, and
130 history functionality at the CVC4 prompt (when running in interactive mode).
131 Check your distribution for a package named "libreadline-dev" or
132 "readline-devel" or similar.
133
134 Note that GNU Readline is covered by the [GNU General Public License, version 3](https://www.gnu.org/licenses/gpl-3.0.en.html).
135 If you choose to use CVC4 with GNU Readline support, you are licensing CVC4
136 under that same license.
137 (Usually CVC4's license is more permissive; see above discussion.)
138
139 ### libboost_thread: The Boost C++ threading library (Portfolio Builds)
140
141 The [Boost](http://www.boost.org) C++ threading library (often packaged
142 independently of the Boost base library) is needed to run CVC4 in "portfolio"
143 (multithreaded) mode.
144 Check your distribution for a package named "libboost-thread-dev" or similar.
145
146 ### Boost C++ base libraries (Examples)
147
148 The [Boost](http://www.boost.org) C++ base library is needed for some examples
149 provided with CVC4.
150
151 ### CxxTest Unit Testing Framework (Unit Tests)
152
153 [CxxTest](http://cxxtest.com) is required to optionally run CVC4's unit tests
154 (included with the distribution).
155 See [Testing CVC4](#Testing-CVC4) below for more details.
156
157
158 ## Building CVC4
159
160 ./configure.sh # use --prefix to specify a prefix (default: /usr/local)
161 # use --name=<PATH> for custom build directory
162 cd <build_dir> # default is ./build
163 make # use -jN for parallel build with N threads
164 make check # to run default set of tests
165 make install # to install into the prefix specified above
166
167 All binaries are built into `<build_dir>/bin`, the CVC4 library is built into
168 `<build_dir>/src`.
169
170 ## Language bindings
171
172 CVC4 provides a complete and flexible C++ API (see `examples/api` for examples).
173 It further provides Java (see `examples/SimpleVC.java` and `examples/api/java`)
174 and Python (see `examples/SimpleVC.py`) API bindings.
175
176 Configure CVC4 with `configure.sh --language-bindings=[java,python,all]`
177 to build with language bindings.
178 Note that this requires SWIG >= 3.0.x.
179
180 In principle, since we use SWIG to generate the native Java and PythonAPI,
181 we could support other languages as well. However, using CVC4 from other
182 languages is not supported, nor expected to work, at this time.
183 If you're interested in helping to develop, maintain, and test a language
184 binding, please contact one of the project leaders.
185
186 ## Building the Examples
187
188 The examples provided in directory `examples` are not built by default.
189
190 make examples # build all examples
191 make runexamples # build and run all examples
192 make <example> # build examples/<subdir>/<example>.<ext>
193 ctest example/<subdir>/<example> # run test example/<subdir>/<example>
194
195 All examples binaries are built into `<build_dir>/bin/examples`.
196
197 See `examples/README` for more detailed information on what to find in the
198 `examples` directory.
199
200 ## Testing CVC4
201
202 We use `ctest` as test infrastructure, for all command-line options of ctest,
203 see `ctest -h`. Some useful options are:
204
205 ctest -R <regex> # run all tests with names matching <regex>
206 ctest -E <regex> # exclude tests with names matching <regex>
207 ctest -L <regex> # run all tests with labels matching <regex>
208 ctest -LE <regex> # exclude tests with labels matching <regex>
209 ctest # run all tests
210 ctest -jN # run all tests in parallel with N threads
211 ctest --output-on-failure # run all tests and print output of failed tests
212
213 We have 4 categories of tests:
214 - **examples** in directory `examples`
215 (label: **example**)
216 - **regression tests** (5 levels) in directory `test/regress`
217 (label: **regressN** with N the regression level)
218 - **system tests** in directory `test/system`
219 (label: **system**)
220 - **unit tests** in directory `test/unit`
221 (label: **unit**)
222
223 ### Testing Examples
224
225 For building instructions, see [Building the Examples](building-the-examples).
226
227 We use prefix `example/` + `<subdir>/` + `<example>` (for `<example>` in
228 `example/<subdir>/`) as test target name.
229
230 make bitvectors # build example/api/bitvectors.cpp
231 ctest -R bitvectors # run all tests that match '*bitvectors*'
232 # > runs example/api/bitvectors
233 # > example/api/bitvectors_and_arrays
234 # > ...
235 ctest -R bitvectors$ # run all tests that match '*bitvectors'
236 # > runs example/api/bitvectors
237 ctest -R example/api/bitvectors$ # run all tests that match '*example/api/bitvectors'
238 # > runs example/api/bitvectors
239
240
241 ### Testing System Tests
242
243 The system tests are not built by default.
244
245 make systemtests # build and run all system tests
246 make <system_test> # build test/system/<system_test>.<ext>
247 ctest system/<system_test> # run test/system/<system_test>.<ext>
248
249 All system test binaries are built into `<build_dir>/bin/test/system`.
250
251 We use prefix `system/` + `<system_test>` (for `<system_test>` in `test/system`)
252 as test target name.
253
254 make ouroborous # build test/system/ouroborous.cpp
255 ctest -R ouroborous # run all tests that match '*ouroborous*'
256 # > runs system/ouroborous
257 ctest -R ouroborous$ # run all tests that match '*ouroborous'
258 # > runs system/ouroborous
259 ctest -R system/ouroborous$ # run all tests that match '*system/ouroborous'
260 # > runs system/ouroborous
261 ### Testing Unit Tests
262
263 The unit tests are not built by default.
264
265 make units # build and run all unit tests
266 make <unit_test> # build test/unit/<subdir>/<unit_test>.<ext>
267 ctest unit/<subdir>/<unit_test> # run test/unit/<subdir>/<unit_test>.<ext>
268
269 All unit test binaries are built into `<build_dir>/bin/test/unit`.
270
271 We use prefix `unit/` + `<subdir>/` + `<unit_test>` (for `<unit_test>` in
272 `test/unit/<subdir>`) as test target name.
273
274 make map_util_black # build test/unit/base/map_util_black.cpp
275 ctest -R map_util_black # run all tests that match '*map_util_black*'
276 # > runs unit/base/map_util_black
277 ctest -R base/map_util_black$ # run all tests that match '*base/map_util_black'
278 # > runs unit/base/map_util_black
279 ctest -R unit/base/map_util_black$ # run all tests that match '*unit/base/map_util_black'
280 # > runs unit/base/map_util_black
281
282 ### Testing Regression Tests
283
284 We use prefix `regressN/` + `<subdir>/` + `<regress_test>` (for `<regress_test>`
285 in level `N` in `test/regress/regressN/<subdir>`) as test target name.
286
287 ctest -L regress # run all regression tests
288 ctest -L regress0 # run all regression tests in level 0
289 ctest -L regress[0-1] # run all regression tests in level 0 and 1
290 ctest -R regress # run all regression tests
291 ctest -R regress0 # run all regression tests in level 0
292 ctest -R regress[0-1] # run all regression tests in level 0 and 1
293 ctest -R regress0/bug288b # run all tests that match '*regress0/bug288b*'
294 # > runs regress0/bug288b
295 ### Custom Targets
296
297 All custom test targets build and run a preconfigured set of tests.
298
299 - `make check [-jN] [ARGS=-jN]`
300 The default build-and-test target for CVC4, builds and runs all examples,
301 all system and unit tests, and regression tests from levels 0 to 2.
302
303 - `make systemtests [-jN] [ARGS=-jN]`
304 Build and run all system tests.
305
306 - `make units [-jN] [ARGS=-jN]`
307 Build and run all unit tests.
308
309 - `make regress [-jN] [ARGS=-jN]`
310 Build and run regression tests from levels 0 to 2.
311
312 - `make runexamples [-jN] [ARGS=-jN]`
313 Build and run all examples.
314
315 - `make coverage [-jN] [ARGS=-jN]`
316 Build and run all tests (system and unit tests, regression tests level 0-4)
317 with gcov to determine code coverage.
318
319 We use `ctest` as test infrastructure, and by default all test targets
320 are configured to **run** in parallel with the maximum number of threads
321 available on the system. Override with `ARGS=-jN`.
322
323 Use `-jN` for parallel **building** with `N` threads.
324
