tools lib traceevent: Add version for traceevent shared object
Adding version support for libtraceevent.so object. Using the existing EVENT_PARSE_VERSION variable to construct the .so object version string, which now consists of: $(EP_VERSION).$(EP_PATCHLEVEL).$(EP_EXTRAVERSION) Looks like it was created for this purpose anyway. The build will now produce following traeceevent libraries: $ ll libtraceevent* libtraceevent.a libtraceevent.so -> libtraceevent.so.1.1.0 libtraceevent.so.1 -> libtraceevent.so.1.1.0 libtraceevent.so.1.1.0 Also the install target will carry them: $ make DESTDIR=/tmp/krava prefix=/usr install INSTALL trace_plugins INSTALL libtraceevent.a INSTALL libtraceevent.so.1.1.0 $ find /tmp/krava/ | xargs ls -l ... /tmp/krava/usr/lib64: total 572 libtraceevent.a libtraceevent.so -> libtraceevent.so.1.1.0 libtraceevent.so.1 -> libtraceevent.so.1.1.0 libtraceevent.so.1.1.0 ...
