Help! I have met the same problem, even if I did it as "Confirmed on my end: if I add back what was removed from AbseilConfigureCopts.make in commit https://github.com/abseil/abseil-cpp/commit/c6954897f7ece5011f0126db9117361dc1a6ff36 then it works."
We need to know exactly what you did before we can help you. Please fill out the bug report form: https://github.com/abseil/abseil-cpp/blob/master/.github/ISSUE_TEMPLATE/00-bug_report.md
This is very likely a mixed-mode build issue. See https://github.com/abseil/abseil-cpp/blob/master/FAQ.md#how-to-i-set-the-c-dialect-used-to-build-abseil.
Closing due to insufficient information.
