Nice. I finally figure out that I need to use --enable-libstdcxx *not* --enable-libstdc++-v3 to build for AVR, and now I get errors due to EOVERFLOW being undefined. Is that what you fixed? We should make that work. Arguably, all values of std::errc should exist, even if the OS <errno.h> doesn't provide a constant. We could define the missing ones ourselves, choosing numbers > 1000 (and hope the OS uses small numbers for its own errno values). > > And a small example with pmr::string and pmr::vector worked :-) Great!
