What version of OR-Tools and what language are you using?
Version: compiled from main
Language: C++
Which solver are you using
CP-SAT
What operating system (Linux, Windows, ...) and version?
Ubuntu 22.04
What did you do?
I have been using ORTools for a few weeks, but today when I re-compiled, it stopped working. I tried installing on my up-to-date home computer and a GCP VM and both failed in the same way, both on Ubuntu 22.04. I am using these simple CMake instructions to configure:
and I compile with
make -j 30
What did you expect to see
No error
What did you see instead?
Since I am using threads for compiling, I also occasionally observe these errors:
Perhaps related, I am also wondering if there are build instructions I could use for disabling parts of the repo that aren't related to CP-SAT
Thanks
