When installing directly from the git repository some additional steps are required. These are not necessary when using the packaged source code. Both require some packages to be installed on the system.
To get CRAVE from the git repository execute the following commands:
git clone https://github.com/agra-uni-bremen/crave-bundle.git
cd crave-bundle
git submodule update --init
This will download crave and its direct dependencies. External dependencies will be downloaded by the bootstrap script when executing make.
Please install the following packages to ensure the external packages will build correctly:
- zlib and bzip2 development libraries (e.g. zlib1g-dev, libbz2-dev)
- CMake
- Python development libraries
- Call 'make' to build CRAVE, the dependencies should automatically download and build.
- Call 'make test', all tests should pass.
- Call 'make install'.
You will find several examples in the examples/ directory. These will demonstrate how to build applications that use CRAVE as well as some core features of CRAVE as listed below:
- ex1_seed_dist : global seed and simple distribution.
- ex2_constr_ref : constraints and references.
- ex3_inh_soft_next : constraint inheritance, soft constraints and custom next().
- ex4_constr_mng : enable/disable constraints.
- ex5_vec_constr : vector constraints.
- ex6_inline_gen : inline generator.
- ex7_randv_enum : constraints on enumeration types.
to execute these examples look into the build/examples directory. See also the test cases in crave/tests which cover all implemented features.
For the build system to build and test the SystemC testcases you need to provide a SystemC config file for CMake. Place this file in your SystemC installation directory (check that the include and library path are correct).
# SystemCConfig.cmake
set(SystemC_VERSION 2.2.0)
## alternative:
# set(SystemC_DIRECTORY /path/to/systemC)
get_filename_component(SystemC_DIRECTORY ${CMAKE_CURRENT_LIST_FILE} PATH)
set(SystemC_INCLUDE_DIR ${SystemC_DIRECTORY}/include )
set(SystemC_INCLUDE_DIRS ${SystemC_INCLUDE_DIR} )
set(SystemC_LIBRARIES ${SystemC_DIRECTORY}/lib/libsystemc.a)
and point cmake to your SystemC directory:
cmake -DSystemC_DIR=/path/to/systemc build/
CRAVE uses the following external dependencies:
In the default configuration CRAVE will use SWORD for its SMT-based constraint-solver. SWORD is provided as binary program for Linux x86 and x86_64 platforms. However this version of SWORD is incompatible with RHEL 5 or derived operating systems (e.g. CentOS 5).
