hello! i'm trying to install OpenROAD using OpenROAD-flow-scripts but there is an error

-- GPU is not enabled
CMake Error at src/mpl2/CMakeLists.txt:42 (find_package):
  By not providing "Findortools.cmake" in CMAKE_MODULE_PATH this project has
  asked CMake to find a package configuration file provided by "ortools", but
  CMake did not find one.
By not providing "Findortools.cmake" in CMAKE_MODULE_PATH this project has
  asked CMake to find a package configuration file provided by "ortools", but
  CMake did not find one.

  Could not find a package configuration file provided by "ortools" with any
  of the following names:

    ortoolsConfig.cmake
    ortools-config.cmake

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

i can not find such package "ortools-config.cmake" to install. i would appreciate it if anyone could help

run following inside

OpenROAD-flow-scripts/tools/OpenROAD

sudo ./etc/DependencyInstaller.sh

local i used

./build_openroad.sh --local

which OS?

ubuntu 22.04

@Vitor Viana Bandeira any idea why getting this error

md5sum: WARNING: 1 computed checksum did NOT match

?

@milad looks like you have run multiple times the installer and the first download of boost was not completed successfully. Can you try to run

rm -rf /tmp/installers

and run the installer again?

yes it worked. @Vitor Viana Bandeira but it stucks at this stage for about 30 minutes.

is it normal?

no, it is not. how many cpus and gigs of ram do you have?

cpu: 3 ram: 4 G

could you try

./build_openroad.sh --threads 1

.

what i get

./build_openroad.sh --threads 1
