Installing CF8 multi-server on a Dell PowerEdge server (64 bit) running Linux
Redhat Enterprise V5

Installed XAMPP for Linux 1.6.6 (Apache 2.2.8, etc.)

After running /opt/jrun4/bin/cf-connector.sh all goes well and the new module
mod_jrun22.so is built and included into Apache's startup file httpd.conf, but
when Apache attempts to restart, get the message below (the last few lines of
cf-connector's log file at /opt/jrun4/Connectorinstall.txt).

I have tried both the 32- and 64-bit versions of CF8, I've tried running
wsconfig directly using the -ws32 switch. I now have about 25 copies of
httpd.conf!!!

If I understand the error correctly, mod_jrun22.so is being built as a 64-bit
object and httpd is needing a 32-bit object.

I have examined every instance of LD_LIBRARY_PATH in the source and build
files to see if there is a 64-bit library referenced and haven't found any.

I'm really hoping someone out there knows what I need to do to fix this.

Thanks in advance!

I am running the ColdFusion developer's 64-bit edition version 8 on the same
machine
running Fedora, I got the same problem.

I tried the Prerelease version. I notified the prerelease staff that I was
getting
a floating point exception, about two-three months ago.

Apparently, the developers ignored the problem.

Brian,

I have learned that the compiler will build a 32- or 64-bit object depending
on the ELFCLASS of the first module it uses during the compile, which in my
(and yours, I suppose) case is 64 bits.

The workaround I found: unzip the wsconfig.jar into a folder:

cd %PathToColdfusion8%/runtime/lib
unzip -d wsconfig_unzip wsconfig.zip

Then navigate into wsconfig_unzip/connectors and find the prebuilt mod that
you need. In my case it was at:
wsconfig_unzip/connectors/apache/intel-linux/prebuilt/mod_jrun22.so

Copy the mod to:
%PathToColdfusion8%/runtime/lib/wsconfig/1/mod_jrun22.so

Start (or restart) ColdFusion and you should be good to go.
