How to Resolve experimental::filesystem Linker Error in C 1z

In C 1z development, users attempting to leverage the new experimental::filesystem library have encountered a linker error. This issue is distinct from C 1z support, as experimental::filesystem is a separate specification.

To resolve the issue, users must link their code with the appropriate library. For GCC 5.3 and later, use the -lstdc fs flag:

g++ main.cpp -O2 -g -o go -lstdc++fs

This library should be placed after any objects that rely on it in the linker command since it is a static library.

Updates:

• November 2017: GCC 8.x introduces an implementation of the C 17 Filesystem library in the std::filesystem namespace. When using -std=gnu 17 or -std=c 17, -lstdc fs is still required.
• January 2019: GCC 9 eliminates the need for -lstdc fs for C 17 std::filesystem components.
• April 2024: GCC 13.3 adds std::experimental::filesystem symbols to -lstdc exp.
