On lxplus, when compiling codes, we found a problem

/cvmfs/atlas.cern.ch/repo/sw/software/21.2/AnalysisBaseExternals/21.2.99/InstallArea/x86_64-centos7-gcc8-opt/include/ROOT/RStringView.hxx:19:23: fatal error: string_view: No such file or directory
 #include <string_view>

We have used

asetup AnalysisBase,21.2.99

and

lsetup cmake

The codes can compile several months but it cannot run now.

Problem Solved. Thanks.

In case someone else ends up here, ROOT backports string_view in header <ROOT/RStringView.hxx> for C++11 and C++14 builds. It picks it up from the STL for C++17 builds (in which case ROOT/RStringView.hxx simply transitively includes <"string_view>").

Cheers,
Enrico
