It's not enabled. I'm suggesting that you enable it, it will solve your problem.

Isn't the code a pretty big clue? #if _GLIBCXX_HOSTED && _GLIBCXX_VERBOSE #ifdef _GLIBCXX_HAVE_UNISTD_H # include <unistd.h> # define writestr(str) write(2, str, sizeof(str) - 1) # ifdef __GNU_LIBRARY__ /* Avoid forcing the library's meaning of `write' on the user program by using the "internal" name (for use within the library). */ /*# define write(fd, buf, n) __write((fd), (buf), (n))*/ # endif #else # include <cstdio> # define writestr(str) std::fputs(str, stderr) #endif #else # define writestr(str) /* Empty */ #endif If you use --disable-hosted-libstdcxx or --disable-libstdcxx-verbose then there's no call to ::write Please stop trying to use Bugzilla to find out how to configure an unsupported version GCC for your target. This is not the right place.
