# FPGA toolchain install script.
# This script installs the full FPGA toolchain into the
# directory specified as INSTALLDIR.
#
# The toolchain will be installed into this directory:
INSTALLDIR="$HOME/fpga-toolchain"
# The following directory will be used as temporary build directory:
BUILDDIR="./toolchain-build"
# Run at most this many build processes in parallel:
PARALLEL="$(getconf _NPROCESSORS_ONLN)"
# The following tools are needed to build the toolchain:
# - gcc
# - clang
# - python3
# - cmake
# - git
#
# Please ensure that all these tools are installed in the system.
