Getting Started

Prerequisites

• Ubuntu 16.04+

Install from Binary

./install.sh

Install from Source

Build Prerequisites

• CMake 3.13+
• A C++11 compiler
• Google glog library
• Clang headers

Build tlpcc

mkdir build
cd build
cmake ..
make
make test
cd ..
sudo ln -s backend/python/tlpc /usr/local/bin/
sudo ln -s build/backend/tlpcc /usr/local/bin/

Known Issues

• Template functions cannot be tasks
• Vivado HLS include paths (e.g., /opt/Xilinx/Vivado/2019.2/include) must not be specified in tlpc --cflags;
  • Workaround is to export CPATH=/opt/Xilinx/Vivado/2019.2/include
