Hello, I am trying to compile deal.II, version 9.2, on CentOS 8.3.2011 (the last version). I have gcc 9.3.0, which is relatively recent. However, when I run cmake, I end up with the following message:
The current combination of compiler and C++ version flag is missing some features of the C++11 version of the language necessary for compiling deal.II. Please ensure that the CMake variable DEAL_II_CXX_VERSION_FLAG is set to the correct flag to enable C++11 support; if it is already set and you still see this message then you will need to upgrade your compiler. I don't really see how this can be, as this version of the compiler fully supports C++11. I also tried setting the flag DEAL_II_CXX_VERSION_FLAG, but using valid standard specifiers just results in errors like "The supplied flag "c++11" was not recognized by the compiler." To be clear, I ran cmake .. -DDEAL_II_CXX_VERSION_FLAG=c++11 The version of cmake is 3.11.4. Any thoughts would be greatly appreciated.
