ILAng requires CMake (3.9.6 or above) and compilers with C++17 support. To install dependencies on Debian-based Linux:

apt-get install bison flex z3 libz3-dev

To install dependencies (besides z3) on Fedora-based Linux:

yum install bison flex

To install dependencies on OSX:

brew install bison flex z3

To build ILAng with default configuration, create a build directory and make:

mkdir -p build && cd build
cmake .. 
make

If you are using git older than 1.8.4, init the submodule from root and disable config-time submodule fetching:

git submodule update --init --recursive
mkdir -p build && cd build
cmake .. -DILANG_FETCH_DEPS=OFF
make

After the build complete, run unit tests (optional) and install the library.

make run_test
sudo make install

• Use -DILANG_FETCH_DEPS=OFF to disable config-time submodule fetching.
• Use -DILANG_BUILD_TEST=OFF to disalbe building the unit tests.
• Use -DILANG_BUILD_SYNTH=ON to enable building the synthesis engine (required Boost).
• Use -DILANG_BUILD_INVSYN=OFF to disable building invariant synthesis feature.
• Use -DILANG_BUILD_SWITCH=ON to enable building smt-switch interface support.
• Use -DILANG_BUILD_COSIM=ON to enable building Xilinx cosimulation support.
• Use -DILANG_INSTALL_DEV=ON to install working features.

You can use the ilang::ilang interface target in CMake. This target populates the appropriate usage requirements for include directories, linked libraries, and compile features. To use the ILAng library, ilang++.h is the file to include. (This does not include working features.)

// cxx source

#include <ilang/ilang++.h>

void foo () {
  auto m = ilang::Ila("new_ila_model");
}

An example can be found in the template repo PrincetonUniversity/template-ila.

To use the ILAng library from a CMake project, you can locate it directly with find_package() and use the namespaced imported target from the generated package configuration:

# CMakeLists.txt

find_package(ilang REQUIRED)

add_library(my_proj ...)

target_link_libraries(my_proj PRIVATE ilang::ilang)

ILAng also supports embedded build, but is not recommended due to its size. To embed the library directly into an existing CMake project, place the entire source tree in a subdirectory and call add_subdirectory() in your CMakeLists.txt file:

# CMakeLists.txt

add_subdirectory(ilang)

add_library(my_proj ...)

target_link_libraries(my_proj PRIVATE ilang::ilang)

To allow your project to support either an externally installed or an embedded library, you can use the following pattern:

# Top level CMakeLists.txt

project(MY_PROJ)

option(MY_PROJ_USE_EXTERNAL_ILANG "Use an external ILAng library" OFF)

add_subdirectory(externals)

add_library(my_proj ...)

target_link_libraries(my_proj PRIVATE ilang::ilang)

# externals/CMakeLists.txt

if(MY_PROJ_USE_EXTERNAL_ILANG)
  find_package(ilang REQUIRED)
else()
  add_subdirectory(ilang)
endif()

externals/ilang is then a complete copy of this source tree, if enabled.

An docker image with the ILAng platform and all dependencies can be fetched from Docker Hub.

docker pull byhuang/ilang:latest

Once the container is initiated, run

source init.sh

to initialize the environment settings. This docker image also contains the model checker CoSA with the SMT solver z3.
