Sure, but they're embarassingly trivial, as my email suggests.
// build with g++ test_temp_path.cpp -lstdc++fs
#include <iostream>
#include <experimental/filesystem>
auto main()->int {
std::cout << "Temp dir: \"" <<
std::experimental::filesystem::temp_directory_path() << "\"" << std::endl;
return EXIT_SUCCESS;
}
Temp dir: "terminate called after throwing an instance of
'std::experimental::filesystem::v1::__cxx11::filesystem_error'
what(): filesystem error: temp_directory_path: Unknown error
Similarly:
// build with g++ test_remove.cpp -lstdc++fs
#include <experimental/filesystem>
auto main()->int {
std::experimental::filesystem::remove("my_file.txt");
return EXIT_SUCCESS;
}
terminate called after throwing an instance of
'std::experimental::filesystem::v
1::__cxx11::filesystem_error'
what(): filesystem error: cannot remove: Unknown error [my_file.txt]

What GCC version is this? Where does the filesystem code come from (patch,
upstream, ...)? It might be incomplete and this error may just be the
library telling you it's not implemented.
