Notes
- ↑ It only works with the std::initializer_list replacement.
(1) --enable-c++11 breaks compilation in base/commandLine.cpp
(2) --enable-c++11 breaks compilation in backends/platform/psp/default_display_client.cpp with error 'bzero' was not declared in this scope. C++11 support is not enabled by default. Compiler fails in default_display_client.cpp before reaching the c++11 test file.
(3) 10.1.0 was tested locally using latest toolchain. Buildbot still uses 8.6.0-based toolchain, which was not tested.
(4) --enable-c++11 breaks compilation in backends/midi/timidity.cpp with multiple errors: 'u_char' was not declared in this scope, 'seqbuf' was not declared in this scope, 'usleep' was not declared in this scope. C++11 support is enabled by default, though, so the flag is not needed.
(5) --enable-c++11 breaks compilation in backends/fs/posix/posix-iostream.cpp with error 'fileno' was not declared in this scope. C++11 support is enabled by default, though, so the flag is not needed.
(6) Missing <initializer_list>, seems to work with the replacement
