Building OpenRoad locally on an Intel mac

[ishwars1618]

Hello, I'm a student learning digital design and would like to use OpenRoad. I am trying to build OpenRoad locally on my Macbook Pro (Catalina MacOS 10.15). I have installed pandas, tcl, libffi etc. using brew, and did a git clone to get the build scripts. However, when building it, I run into first "readlink: illegal option -- f", and then errors below (after which I aborted the build).

kernel/driver.cc:178:4: error: use of undeclared identifier 'append_history'
append_history(where_history() - yosys_history_offset, yosys_history_file.c_str());
^
kernel/driver.cc:188:27: error: use of undeclared identifier 'history_list'
HIST_ENTRY **hist_list = history_list();

Not sure how to fix the errors.
Can anyone share a complete setup for building OpenRoad locally on a Mac?
Thanks.

• Have you run the dependency installer script at OpenROAD-flow-scripts/tools/OpenROAD/etc/DependencyInstaller.sh?
• Did you update your PATH using the suggested commands from the installer?
• Can you please provide your complete build log? The errors look like they're coming from yosys, not openroad.

Thanks for the suggestion! I installed those with brew, and the rebuild went through almost the entire build process until it reached this error below. Attached the CMakeError.log as well.
CMakeError.log

It is more helpful to attach the CMake log rather than just just CMakeError.log.

Do you have Apple Clang installed? I don't think we support GCC on mac (at least, it is not well test). Otherwise the error means that you need to use a compiler that has OpenMP installed.

I installed the Xcode command-line tools successfully - so assuming Apple Clang comes with it. Attaching the CMakeOutput.log now. What do I need to use a compiler that has OpenMP installed?

CMakeOutput.log

Verified that Clang is installed (please see below)
% clang --version
Apple clang version 12.0.0 (clang-1200.0.32.29)

@ishwars1618 as Austin mentioned, the DependencyInstaller.sh is a good option to automatically install the dependencies, you can check a more manual approach here. Note the exports and how to call cmake.
