Ruby Driver: Ingres.so: undefined symbol: IIMEreqmem

[sucha]

Hi,

I'm having trouble installing Ingres Ruby Driver on Ubuntu Hardy system. Building goes okay (except for a warning - see below), but I can't use the driver in ruby:
$ irb
irb(main):001:0> require 'Ingres'
LoadError: /usr/local/lib/site_ruby/1.8/i486-linux/Ingres.so: undefined symbol: IIMEreqmem - /usr/local/lib/site_ruby/1.8/i486-linux/Ingres.so
from /usr/local/lib/site_ruby/1.8/i486-linux/Ingres.so
from (irb):1

Software version:
Ingres Ruby Driver v 1.3.1 & svn revision 1717
ruby1.8 1.8.6.111-2ubuntu1.2

$ uname -s -r -m
Linux 2.6.24-24-server i686

$ cat $II_SYSTEM/ingres/version.rel
II 9.2.0 (int.lnx/143)NPTL

Build output:

$ make

$ sudo make install
/usr/bin/install -c -m 0755 Ingres.so /usr/local/lib/site_ruby/1.8/i486-linux

I don't know what I'm doing wrong. Thanks for any help.

Best Regards

Hi Anton,

What does the output from the following command show:

ldd /usr/local/lib/site_ruby/1.8/i486-linux/Ingres.so

Building the Ruby driver against the standard Ruby packages for Ubuntu 9.04 seems to work fine for me:

Hi Grant,

Thanks for reply. You were right, ldd output did not show ingres libraries:

$ ldd /usr/local/lib/site_ruby/1.8/i486-linux/Ingres.so
        linux-gate.so.1 =>  (0xb7fb9000)
        libruby1.8.so.1.8 => /usr/lib/libruby1.8.so.1.8 (0xb7ea9000)

        libdl.so.2 => /lib/tls/i686/cmov/libdl.so.2 (0xb7e8c000)

        /lib/ld-linux.so.2 (0xb7fba000)

I tried to rebuild as ingres user and now it works perfectly (I built it as other user before, maybe I forgot to set an environment variable or something). Thanks again for your help.

Best Regards

Anton

Hi Grant,

I further investigated the issue and found out that the difference was not which user I used to build the driver, but how I invoked extconf.rb.

I invoked extconf.rb as per README yesterday:

$ ruby -r mkmf extconf.rb --with-ingres-include='/opt/ingres/ingres/files/' --with-ingres-lib='/opt/ingres/ingres/lib'
Start extconf.rb
Using supplied directories:
Headers   - /opt/ingres/ingres/files/
Libraries - /opt/ingres/ingres/lib
checking for iiapi.h... yes
checking for main() in -liiapi... yes
creating Makefile

$ make
cc -I. -I. -I/usr/lib/ruby/1.8/i486-linux -I. -DHAVE_IIAPI_H -I/opt/ingres/ingres/files/  -fPIC -fno-strict-aliasing -g -g -O2  -fPIC  -c Ingres.c
Ingres.c: In function âgetColumnNamesAndTypesâ:

$ ldd Ingres.so
        linux-gate.so.1 =>  (0xb7ee7000)
        libruby1.8.so.1.8 => /usr/lib/libruby1.8.so.1.8 (0xb7dd7000)
        libpthread.so.0 => /lib/tls/i686/cmov/libpthread.so.0 (0xb7dbf000)
        libdl.so.2 => /lib/tls/i686/cmov/libdl.so.2 (0xb7dba000)
        libcrypt.so.1 => /lib/tls/i686/cmov/libcrypt.so.1 (0xb7d88000)
        libm.so.6 => /lib/tls/i686/cmov/libm.so.6 (0xb7d63000)
        libc.so.6 => /lib/tls/i686/cmov/libc.so.6 (0xb7c14000)
        /lib/ld-linux.so.2 (0xb7ee8000)

However, I invoked it as per your output today:

$ ruby extconf.rb

        libpthread.so.0 => /lib/tls/i686/cmov/libpthread.so.0 (0xb7aa6000)
        libdl.so.2 => /lib/tls/i686/cmov/libdl.so.2 (0xb7aa1000)
        libcrypt.so.1 => /lib/tls/i686/cmov/libcrypt.so.1 (0xb7a6f000)
        libm.so.6 => /lib/tls/i686/cmov/libm.so.6 (0xb7a4a000)
        libc.so.6 => /lib/tls/i686/cmov/libc.so.6 (0xb78fb000)
        /lib/ld-linux.so.2 (0xb7fbb000)

As you can see, library related parameters to GCC are different in both cases. Is this a bug in extconf.rb? Perhaps you could update the README so that users run just "ruby extconf.rb" first and then to try to override library paths if necessary?

Thanks

Best Regards
