std::ptr_fun was deprecated in C++11, and removed completely in C++17. Similarly, std::not1 is deprecated since C++17. Modern compilers like clang >= 16 have started to notice it src/FatUtils.h:41:46: error: use of undeclared identifier 'ptr_fun' | s.erase(find_if(s.rbegin(), s.rend(), not1(ptr_fun<int, int>(isspace))).base(), s.end()); Therefore replace ptr_fun with lambda Also use 'unsigned char' parameter to std::isspace, for reason see [1] [1] https://en.cppreference.com/w/cpp/string/byte/isspace#Notes Signed-off-by: Khem Raj <raj.khem@gmail.com>

src/FatUtils.h:41:46: error: use of undeclared identifier 'ptr_fun'
| s.erase(find_if(s.rbegin(), s.rend(), not1(ptr_fun<int, int>(isspace))).base(), s.end());
Therefore replace ptr_fun with lambda
Also use 'unsigned char' parameter to std::isspace, for reason see [1]
