Hi Andrew

I checked libc.a using nm and .__memmove is defined. The following is the compile/load line where it fails

gcc -W1,-soname=x.so -o x.so .*I6.o -shared   -Wall -D__USE_GNU -D_GNU_SOURCE -DDEBUG -DLEAVE_OUT_REV_ID -O2 -D_ALL_SOURCE -Drs6000  -D__EXTENSIONS__ -I/usr/openwin/include -DAIX53 -U__MATH__ -DAIX  -DRS6000 -fPIC -L<libpath> -lsbI6 -L<libpath> -ldbI6
/lib/libc.a(moveeq.o):moveeq.s:(.pr+0xc): undefined reference to `.___memmove'

I think as you have suggested, I may have compiled and installed gcc incorrectly.

Hope this helps. Thanks much for your help.

With Regards

Vardhan

`.___memmove' is missing.

Yes.

You've probably incorrectly installed gcc.
