From the shell

$ export LD_DEBUG=bindings
  and run it, for more options type

$ export LD_DEBUG=help
  and run something, it would spit out more stuff.

Also just use
$ ldd /yourdir/yourlib.so
  to get info how it's loading

Check your ldconfig cache

$ /sbin/ldconfig -p
  it prints how the system would find your dynamic shared objects.

I've compiled and used both of these before on an x86 system without

Various modules of LuaGnome fail to compile, and then the library won't load:

$ make gdk

build/linux-amd64/gdk/link.h
build/linux-amd64/gdk/init.o

This, I (possibly) fixed by changing script/parse-xml.lua around line 230:
  if config.lib.aliases then
        for to, from in pairs(config.lib.aliases) do
            --assert(xml.funclist[from])
            --assert(not xml.funclist[to])
            if xml.funclist[from] and not xml.funclist[to] then
                    function_list[#function_list + 1] = to
                    xml.funclist[to] = from
                    _function_analyze(from)
            end
        end

LuaGL compiles and loads, but all constants (e.g. gl.PROJECTION) are
missing. Only the functions remain.

Well I've figured out why LuaGnome fails: it's not looking in
/usr/lib/x86_64-linux-gnu and
/usr/lib/x86_64-linux-gnu/glib-2.0/include which seem to be where all
my stuff is. However I can't figure out how to fix this. No matter
where I stick pkg-config in makefiles and config scripts it doesn't
seem to notice.

As a temporary fix I symlinked
/usr/lib/x86_64-linux-gnu/libg{object,module,thread}-2.0.so.0 into
/usr/lib; that gets the library to load at least, though lacking a few
modules I still haven't been able to compile.
