Help! Libc dynamic library problem

Thanks for reply.

I have tried your sulotion,but it dose not work with the same error.

I have tried another sulotion,changing -Ctarget-feature=crt-static to -Ctarget-feature=-crt-static ,then it gose run with error " 'calloc' undefine references".

Dose crt-static introduce the definition of calloc? So Confused!
