Hi all,
I have been looking for shared libraries preparation in lib sources.
Seems like you should compile with -fpic and -DBSDSHLIB and later link with
ld -B shareable -o libfoo.so.M.M $(OBJECTS).
But sometimes after compiling ld -x -r is run on each object file
(ld manual says its for striping unexported symbols).
May someone point why and when is this necesary (or if it exists point to the
documentation)?
Also if possible, may someone compare FreeBSD shared libraries with other
unixes implementation? At first they look like the ones in SunOS 4.
Thanx in advance,
-cristian
