> times(NULL) = -1930357195
Could you ask to your oracle support whether your oracle version hits a bug that 32-bit applications hang when the server clock tick is over 2G?
Could you reboot your machine and check whether the issue is gone?

Hi,
So its a very weird environment, uses Bitnami stack (live a virtual environment - inc 32 bit ruby) running on 64 bit linux red hat.
The strace command returns load of lines of format :
times(NULL) = -1930357195
times(NULL) = -1930357195
times(NULL) = -1930357195
strace, ltrace, pstack and gdb commands are not found.
I have tried upgrading the bitnami stack to 64bit and installed ruby ok and it talks to oracle but I cant get oracle enhanced adapter working with it.
We are also sort of tied into 32 bit for connection to a another db - TERADATA via unixodbc.
Here is the last 100 lines of mkmf.log ...

What platform do you use?
If it is linux, post the results of following commands:
* run 'top' command and check whether the hung process is consuming CPU.
* run 'strace -p PID_OF_HUNG_PROCESS' and stop it by Control-C after 10 seconds.
* run 'ltrace -p PID_OF_HUNG_PROCESS' and stop it by Control-C after 10 seconds.
* run 'pstack PID_OF_HUNG_PROCESS'. If pstack is not found, run 'gdb `which ruby` PID_OF_HUNG_PROCESS' and then type 'bt' and 'quit'.

Hi Kubo,
Many thanks for the reply - this has now compiled ok but when I try to use oci8 it just hangs...
irb(main):001:0> require 'rubygems'
=> false
irb(main):002:0> require 'oci8'
Anyideas where I can look,
Many thanks
Ben

Did you use ruby compiled on 32 bit platform?
mkmf.rb gets compiler options from rbconfig.rb in archdir.
ruby -r rbconfig -e "puts Config::CONFIG['archdir']"
Change CC entry in rbconfig.rb as follows:
CONFIG["CC"] = "gcc -m32"

Hi,
Whilst running make I get :
Error Message:
C compiler doesn't work correctly.
I have 32 oracle client installed, 32 bit ruby and 64 bit machine. Looking at mkmf.log I see this :
/usr/bin/ld: skipping incompatible libruby-static.a when searching for -lruby-static.
I pulled out command to check cc and get same error, if I manually add -m32 flag to gcc it works.
How can I force the make to build in 32 bit mode ?
Nay help / tips gratefully received, struggling to move forward at the moment.
many thanks
Ben
