sgtk_dlopen

[Daniel Skarda]

Hello,

  for guile-gtk developmemt I would like to have two guile-gtk installed (one
"stable" and one with my modifications). So I added gtkconf-libdir to config.scm.in
and updated appropriate places in dynlink.scm and configure.in. The main
problem is that guiledlopenhelper.c:sgtk_dlopen uses `name' instead of
`fullname' (when RTLD_GLOBAL is defined) - so dynlink always opens "stable"
version instead of the other one.

  Do you think that change `name' -=> `fullname' would break something?

Dan

ps: what do you think about libltdl which comes with new version of libtool?

I'm not sure, but I don't expect any breakage.  I'm pretty agnostic
about dynamic linking issues right now.  Does it help to have a
different LD_LIBRARY_PATH when running your unstable version?

Definitely worth a look, but I rather put it into libguile and do away
with the dynlinking hacks of guile-gtk completely.  I even have a
patch for libguile by one of the libltdl authors...

Yeah, I think I have to do something about this mess.  I'll wait until
after guile-gtk-0.17, tho.
