You need to add the library to the gcc command that links the program. If the libndbm is in the library search path, add -lndbm.

It should be doing this with -lm. --joel On Fri, Jun 28, 2019, 8:12 AM Vaibhav Gupta <vaibhavgupt...@gmail.com> wrote: > Hello, > . > Status: > > 1. I have ported ndbm in newlib.
