Auto Installation of Tools

source build/envsetup.sh arm release
make setup

Note: the following steps are for reference only. All required tools are installed during above "make setup"

Installing and Configuring Clang (for Compiling the OpenArkCompiler Code)

Download clang+llvm-8.0.0-x86_64-linux-gnu-ubuntu-16.04 LLVM download address: http://releases.llvm.org/download.html#8.0.0

Place the downloaded files in the openarkcompiler/tools directory, open the openarkcompiler/build/config.gni file, and set the three variables GN_C_COMPILER, GN_CXX_COMPILER, and GN_AR_COMPILER to the path where Clang is located. For example:

GN_C_COMPILER = "${MAPLE_ROOT}/tools/clang+llvm-8.0.0-x86_64-linux-gnu-ubuntu-16.04/bin/clang"
GN_CXX_COMPILER = "${MAPLE_ROOT}/tools/clang+llvm-8.0.0-x86_64-linux-gnu-ubuntu-16.04/bin/clang++"
GN_AR_COMPILER = "${MAPLE_ROOT}/tools/clang+llvm-8.0.0-x86_64-linux-gnu-ubuntu-16.04/bin/llvm-ar"

${MAPLE_ROOT} is the root directory of the OpenArkCompiler source code.

Installing and configuring Ninja and GN

Download Ninja(v1.10.0) and GN(Linux Version) Ninja download address: https://github.com/ninja-build/ninja/releases GN download address: https://gitee.com/xlnb/gn_binary

Place the executable programs of GN and Ninja in the openarkcompiler/tools directory, modify these two files to be executable.

cd openarkcompiler/tools
chmod 775 gn
chmod 775 ninja

Open the openarkcompiler/Makefile file, and set the two variables GN and NINJA to the path where the executable programs of GN and Ninja are located. For example,

GN := ${MAPLE_ROOT}/tools/gn/gn
NINJA := ${MAPLE_ROOT}/tools/ninja/ninja
