Building the executable with CMake

Building scala-native-bindgen requires the following tools and libraries:

• CMake version 3.9 or higher
• GNU Make
• LLVM and Clang version 5.0 or 6.0.
• nlohmann/json version 3.1.2 or higher

# On apt-based systems
apt install cmake make clang-6.0 libclang-6.0-dev llvm-6.0-dev \
            nlohmann-json-dev

# With `brew`
brew tap nlohmann/json
brew install cmake llvm@6 nlohmann_json

To run the tests you also need the required Scala Native libraries. See the Scala Native setup guide for instructions on installing the dependencies.

mkdir -p bindgen/target
cd bindgen/target
cmake ..
make
./scala-native-bindgen --name ctype /usr/include/ctype.h --

To build a statically linked executable pass -DSTATIC_LINKING=ON when invoking cmake:

cmake -DSTATIC_LINKING=ON ..

Additional compiler and linker flags may be passed as environment variable sor their CMake equivalent, e.g. to compile with debug symbols the following are the same:

cmake -DCMAKE_CXX_FLAGS=-g ..
CXXFLAGS=-g cmake ..
