I'm trying to compile the BerkeleyDB ruby extension into the ruby
executable for ruby 1.8.2. I've placed the extension directory
underneath the <ruby>/ext directory. When I do configure and make the
build process tries to build the BerkleyDB extension but it fails
because it can't find the Berkeley libraries. Normally when building
this extension you have to specifiy the --with-db-dir=<db dir>
parameter when running the extconf.rb file. But I cannot figure out
how to pass this same information into the configure/make process for
ruby. Anyone have any ideas regarding this?

you don't need to put it into ruby-1.8.2/ext

* Install normally ruby

* extract bdb-0.5.4 *outside* the ruby directory

* then run

ruby extconf.rb --with-db-dir=...
make
make install

RIght...I've got that part. But what I'm trying to do is compile and
statically link the extension into the ruby executable itself. I've
created an entry in the <ruby>/ext/Setup file for bdb so that it will
try and build it when Ruby builds. When I try to make ruby it will
actually try and compile the bdb extension, but without passing in the
--with-db-dir parameter. I need to know how to pass this parameter
through to the extconf.rb file for the bdb extension when running the
make file for ruby.

actually try and compile the bdb extension, but without passing in the
--with-db-dir parameter. I need to know how to pass this parameter
through to the extconf.rb file for the bdb extension when running the
make file for ruby.

Then give the option to configure. Ruby's configure passes unknown
options to extmk.rb, which then use that options to make extension
libraries.

There is a bug in extconf.rb for bdb, not really a surprise for me

Try it with

uln% cd ext
uln%

uln% tar zxf ~/ruby/perso/db/bdb-0.5.4.tar.gz
uln%

uln% rm -r bdb-0.5.4/extconf.rb bdb-0.5.4/bdbxml*
uln%

uln% cd ..
uln%

uln% tail -1 ext/Setup
bdb-0.5.4/src
uln%

uln% ./configure --prefix=$HOME/local/r182 --with-db-dir=$HOME/local/db4.3.21 > /dev/null
uln%

uln% make
