plruby: --enable-static-ruby / --disable-shared ?

[David Garamond]

What about adding these configure option, so plruby.so doesn't need
libruby.so at all? But sorry, I'm still not sure how to modify
extconf.rb to accomplish this. In the Makefile I just replace LIBS=
$(LIBRUBYARG_SHARED) with $(LIBRUBYARG_STATIC).

What is your version of plruby and ruby ?

If I create with -lruby-static (no -lruby):

If I use a static ruby (ruby configured with --disable-shared), I can't
get the resulting plruby.so to work (no ruby runtime linked).

Thanks,

Don't link libruby-static.a to shared objects. It is for
executables without libruby.so, e.g. conftest, but not for
extension libraries.

plruby is not an extension library.

This is just that ruby was, in this case, compiled with --enable-shared

Well, this is a little more complex. Try it with

ruby extconf.rb --with-pgsql-include=/usr/include/pgsql \
--with-safe-level=0 --enable-geometry --enable-network

find . -name '*so'

I'm not really sure that you want $(LIBRUBYARG_STATIC) in this case

Thanks, with --safe-level it works (though I don't understand why/what
it does).

I wanted to statically link libruby.so because I intend to distribute
plruby.so to machines where there might not be Ruby installed (or Ruby
might installed in a different location). Though thinking about it
again, I realize I can always distribute libruby.so along...

Except that it's a very *BAD* idea and don't repeat that this option exist
(it's voluntary *NOT* documented)

If you compile it with --enable-... and $SAFE < 3 it will create

svg% find . -name '*so'
/src/conversions/geometry/plruby_geometry.so
/src/conversions/network/plruby_network.so
/src/conversions/basic/plruby_basic.so
/src/plruby.so
svg%


This means that plruby_{basic,geometry,network}.so will also be compiled
with the static version of libruby

Try this

svg% diff -ru plruby-0.3.9 plruby-0.4.0 [snip]
and use --disable-shared

Thanks!
