commit r15-921-g5955c18dfb970740d55d432aeee5cb5a6f51cf65 Author: Alexandre Oliva <ol...@adacore.com> Date: Thu May 30 04:01:15 2024 -0300 [libstdc++-v3] [rtems] enable filesystem support mkdir, chdir and chmod functions are defined in librtemscpu, that doesn't get linked in during libstdc++-v3 configure, but applications use -qrtems for linking, which brings those symbols in, so it makes sense to mark them as available so that the C++ filesystem APIs are enabled. for libstdc++-v3/ChangeLog * configure.ac [*-*-rtems*]: Set chdir, chmod and mkdir as available. * configure: Rebuilt.
