The ld returned 1 exit status error is the consequence of previous errors  In your example there is an earlier error - undefined reference to  clrscr  - and this is the real one  The exit status error just signals that the linking step in the build process encountered some errors  Normally exit status 0 means success  and exit status   0 means errors   When you build your program  multiple tools may be run as separate steps to create the final executable  In your case one of those tools is ld  which first reports the error it found  clrscr reference missing   and then it returns the exit status  Since the exit status is   0  it means an error and is reported   In many cases tools return as the exit status the number of errors they encountered  So if ld tool finds two errors  its exit status would be 2

In your situation you got a reference to the missing symbols  But in some situations  ld will not provide error information   If you want to expand the information provided by ld  just add the following parameters to your   LDFLAGS   -Wl -V
