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

David_Garamond2 · 5 March 2004 10:51

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 ?

svg% ruby extconf.rb --with-pgsql-dir=$HOME/local/pgsql
checking for ruby_init() in -lruby-static... yes
checking for catalog/pg_proc.h... yes
checking for PQsetdbLogin() in -lpq... yes
checking for rb_hash_delete()... yes
checking for server/utils/array.h... yes
creating Makefile

========================================================================
After the installation use something like this to create the language
plruby

   create function plruby_call_handler() returns language_handler
   as '/usr/local/lib/ruby/site_ruby/1.8/i686-linux/plruby.so'
   language 'C';

   create trusted language 'plruby'
   handler plruby_call_handler
   lancompiler 'PL/Ruby';

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

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, 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…

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

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

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

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

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

extension libraries.

plruby is not an extension library.

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