The test program which uses regex
For more information, see
<a href="https://stackoverflow.com/questions/26245167/compiling-regex-program-in-clang-for-libstdc-in-c14-mode-causes-errors">https://stackoverflow.com/questions/26245167/compiling-regex-program-in-clang-for-libstdc-in-c14-mode-causes-errors</a>
The libstdc++ binary is libstdc++.so.6.0.20
The following test program works fine with the following command lines for the
attached test program (using gcc 4.9.1):
g++4.9 -std=c++11 test.cpp
g++4.9 -std=c++1y test.cpp
g++4.9 -std=c++14 test.cpp
clang++ -stdlib=libstdc++ -std=c++11 test.cpp
clang++ -stdlib=libc++ -std=c++11 test.cpp
clang++ -stdlib=libc++ -std=c++1y test.cpp
clang++ -stdlib=libc++ -std=c++14 test.cpp
clang++ -stdlib=libc++ -std=c++1z test.cpp
When using the following command lines:
clang++ -stdlib=libstdc++ -std=c++1y test.cpp
clang++ -stdlib=libstdc++ -std=c++14 test.cpp
clang++ -stdlib=libstdc++ -std=c++1y test.cpp
it fails to compile with the following errors:
