Hello, I am reading about memcpy to write it for newlib. Should I also write wmemcpy along with it? https://pubs.opengroup.org/onlinepubs/009695399/functions/wmemcpy.html . Regarding ndbm reference. RSB has not generated library files. - but in newlib source tree, when I compiled newlib, while porting ndbm, it generated *lib_a-ndbm.o* object file. - I am planning to use that object file to compile ndbm testsuite. . When Object file and C file are present in same directory, we can use : $ gcc trial.c mylib.o But I am not able to find out, how to use this in Makefile.am. LDADD replaces all global variables while compiling.
I tried various codes, but could not solve it. I just want to use the object file (lib_a-ndbm.o) created while building newlib, to compile ndbm testsuite. I need guidance for this.
