I just got gcc 4.6 built successfully. I was trying libquadmath with the following test code: http://gcc.gnu.org/onlinedocs/libquadmath/quadmath_005fsnprintf.html#quadmath_005fsnprintf but I get the following errors: /site/ae/shares/MotionLab/papers/pingpong/examples/LongDoublePrecisionTests/test.cpp:13: undefined reference to `sqrtq(__float128)' /site/ae/shares/MotionLab/papers/pingpong/examples/LongDoublePrecisionTests/test.cpp:14: undefined reference to `quadmath_snprintf(char*, unsigned int, char const*, ...)' /site/ae/shares/MotionLab/papers/pingpong/examples/LongDoublePrecisionTests/test.cpp:18: undefined reference to `quadmath_snprintf(char*, unsigned int, char const*, ...)' /site/ae/shares/MotionLab/papers/pingpong/examples/LongDoublePrecisionTests/test.cpp:22: undefined reference to `quadmath_snprintf(char*, unsigned int, char const*, ...)' /site/ae/shares/MotionLab/papers/pingpong/examples/LongDoublePrecisionTests/test.cpp:28: undefined reference to `quadmath_snprintf(char*, unsigned int, char const*, ...)' /site/ae/shares/MotionLab/papers/pingpong/examples/LongDoublePrecisionTests/test.cpp:18: undefined reference to `quadmath_snprintf(char*, unsigned int, char const*, ...)' What am I missing here. I tried specifying -lquadmath but that didn't help!! -- View this message in context: http://old.nabble.com/undefined-reference-to-libquadmath-routines-tp31790381p31790381.html Sent from the gcc - Help mailing list archive at Nabble.com.
