Building from source OR-Tools C++ on Linux results in compile error

[troyrock]

What version of OR-Tools and what language are you using?
Version: stable/v9.11
Language: C++

Which solver are you using (e.g. CP-SAT, Routing Solver, GLOP, BOP, Gurobi)
I intend to try Gurobi but I'm not sure if it is getting that far.

What operating system (Linux, Windows, ...) and version?
NAME="Red Hat Enterprise Linux"
VERSION="8.8 (Ootpa)"

What did you do?
git clone https://github.com/google/or-tools
cd or-tools
cmake -S . -B build -DBUILD_DEPS=ON
cmake --build build --config Release --target all -v

What did you expect to see
Compile successful! or something like that.

What did you see instead?
a LOT of successful compilations followed by:

Make sure you include information that can help us debug (full error message, model Proto).

[lperron]

most likely a version of gcc too old.

[troyrock]

I updated to gcc 11.2.0 and that fixed the problem. Thank you.

Thx for the update, appreciate it !
