ghanesimit commented 4 years ago

I have followed below link to download tool on ubuntu 16.04. http://www.clifford.at/icestorm/

Where I am facing issue while installing nextpnr as below.

$ cmake -DARCH=ice40 -DCMAKE_INSTALL_PREFIX=/usr/local . -- Boost version: 1.58.0 -- Found the following Boost libraries: -- filesystem -- thread -- program_options -- iostreams -- system -- chrono -- date_time -- atomic -- regex CMake Error at CMakeLists.txt:197 (find_package): Could not find a package configuration file provided by "Eigen3" with any of the following names:

Eigen3Config.cmake
eigen3-config.cmake

Add the installation prefix of "Eigen3" to CMAKE_PREFIX_PATH or set "Eigen3_DIR" to a directory containing one of the above files. If "Eigen3" provides a separate development package or SDK, be sure it has been installed.

-- Configuring incomplete, errors occurred! See also "/home/SLSCORP/simit.ghane.457/Desktop/USB_2019/RISC_V/nextpnr/CMakeFiles/CMakeOutput.log". See also "/home/SLSCORP/simit.ghane.457/Desktop/USB_2019/RISC_V/nextpnr/CMakeFiles/CMakeError.log".

Please guide me.

Please use the nextpnr repository for nextpnr issues in the future.

In this case you need to install libeigen3-dev
