For whatever it's worth, we went down the "libtool" path for a while in
FlightGear and decided at the time that the headaches a weirdness of libtool
simply wasn't worth the effort. The build system got much simpler when we
moved to static libs.
That's not to say that we can't find some advantages to shared libs,
generally there aren't too many, but in the case of building several
versions of the FG binary, I can see the benefit. But on the whole, I'd
really prefer to stick with static libs, and would really prefer to avoid
libtool. For instance, I always had a little trouble getting gdb to work on
a wrapper script. :-) Libtool for those that don't know, imposes a couple
layers of indirection and wrapper scripts on top of everything so that you
can "sort of" run the resulting executable out of your build tree without
installing it first, but life starts to get more difficult when you start
trying to do debugging, or need to figure out what's really going on with
your libraries, often times it's very difficult to find the actual library
since libtool is pretty good at hiding everything from you.
I suppose I ended up on my soap box again here, sorry about that. :-)
I have no problem with people using libtool for genuine shared library
packages; it can make a lot of sense there. But for FlightGear/SimGear we
found that it ended up causing more headaches than it cured.
Regards,
Curt.
