mkmf and oracle problem - not detecting header files

[Daniel Berger]

Hi all,

Oracle 9.2.0.4
Mandriva Linux 2.6.8.1
Ruby 1.8.2

I suspect I need a good dose of caffeine, because I can't figure out why
the ruby-oci package isn't picking up the Oracle header files. To
simplify things as much as possible, I created a test extconf.rb script
that looks like this:

# extconf.rb
require "mkmf"
dir_config("oracle")
have_header("oci.h")

# To demonstrate that the oci.h file does exist

ls /home/oracle/9204/rdbms/demo/oci.h

/home/oracle/9204/rdbms/demo/oci.h

I tried several different things - what am I doing wrong?

ruby extconf.rb

checking for oci.h... no

ruby extconf.rb --with-oracle-dir=/home/oracle/9204

checking for oci.h... no

ruby extconf.rb --with-oracle-dir=/home/oracle/9204/rdbms/demo

checking for oci.h... no

ruby extconf.rb --with-oracle-include=/home/oracle/9204/rdbms/demo

checking for oci.h... no

Regards,

Dan

Have you set your ORACLE_HOME environment variable to the directory
containing 'rdbms/demo/oci.h', in your case /home/oracle/9204?

run a 'printenv ORACLE_HOME' to see if it shows up as such.

if not, then depending on your shell:
export ORACLE_HOME=3D/home/oracle/9204

printenv ORACLE_HOME

/home/oracle/9204

Yep, though it shouldn't matter for my mini example.

echo $SHELL

/bin/bash

Any other ideas?

I don't think your short test extconf.rb would work here, as the
have_header directive after the dir_config specifically looks in an
'include' subdirector for header files, and as it stands Oracle's
installation of oci.h is in an odd place of rdbms/demo/oci.h.

I believe that ruby-oci (8, at least) plays around with setting some
environment variables and search paths based on the ORACLE_HOME
variable before it does it's own have_header('oci.h') test.

Which ruby-oci package are you trying this out on? 8? 9? Is it
failing to install or run afterwards?

You should show the mkmf.log file, if you have a problem with
extconf.

How about using oraconf.rb in ruby-oci8.
http://rubyforge.org/cgi-bin/viewcv...aconf.rb?cvsroot=ruby-oci8&only_with_tag=MAIN

# extconf.rb
require "mkmf"
require File.dirname(__FILE__) + '/oraconf'
oraconf = OraConf.new()
$CFLAGS += oraconf.cflags
$libs += oraconf.libs

# To demonstrate that the oci.h file does exist
/home/oracle/9204/rdbms/demo/oci.h

The simpest way is:

# extconf.rb
require "mkmf"
oracle_home = ENV['ORACLE_HOME']
$CFLAGS += " -I#{oracle_home}/rdbms/demo -I#{oracle_home}/rdbms/public "
$libs += " -L#{oracle_home}/lib -lclntsh "
have_header("oci.h")

It will work on Oracle 9i or later.
