The Makefile is processed from Makefile.in, with symbols resolved, e.g.
.c.o:
$(CC) -c @CFLAGS@ -I. -I.. @INCS@ -DHAVE_CONFIG_H $<
->
.c.o:
$(CC) -c -g -O2 -I/usr/local/include -Wshadow -Wpointer-arith -Wmissing-prot
otypes -Wmissing-declarations -Wnested-externs -fPIC -I. -I.. -I/root/ntop
/myrrd -DHAVE_CONFIG_H $<
That should be fine, because the externs are just that (external) until
either linkage or loading occurs.
However, not having symbols in the .so library makes no sense (certainly
they're there in the 1.8.4 installed from gd-devel-1.8.4-9 / gd-1.8.4-9.
Quoting man nm: "GNU nm lists the symbols from object files objfile...."
Unless that is a stripped library? You may need to find another tool...
check the man pages for nm, ar, ranlib, readelf, etc. maybe you'll find
hints in there.
I don't have any other ideas here...

Now I am completely confused... :(
