Toolchain Dependencies
Install development tools
$ sudo apt-get install build-essential
$ sudo apt-get install git
Install Vortex codebase
$ git clone --recursive https://github.com/vortexgpgpu/vortex.git
$ cd Vortex
Install prebuilt toolchain
$ ./ci/toolchain_install.sh --all
By default, the toolchain will install to /opt folder.
You can install the toolchain to a different directory by overiding DESTDIR.
$ DESTDIR=$TOOLDIR ./ci/toolchain_install.sh --all
$ export VORTEX_HOME=$TOOLDIR/vortex
$ export LLVM_VORTEX=$TOOLDIR/llvm-vortex
$ export LLVM_POCL=$TOOLDIR/llvm-pocl
$ export RISCV_TOOLCHAIN_PATH=$TOOLDIR/riscv-gnu-toolchain
$ export VERILATOR_ROOT=$TOOLDIR/verilator
$ export PATH=$VERILATOR_ROOT/bin:$PATH
Build Vortex sources
$ make -s
