When trying to compile the driver on RHEL 5 I get this error:  
rpmbuild --rebuild /pp40/RPMS/kernel/40002347\_c.src.rpm  
.  
.  
.  
checking for current kernel version… 2.6.18-8.1.15.el5 -\> 2.6.18-8.1.15.5 -\> 2.6.18  
checking for kernel headers… “Not found.”

* * *

- Unable to locate matching kernel source for the
- linux 2.6.18-8.1.15.el5 kernel that is currently running!
- 
- The Digi DGAP driver requires this linux kernel source to be
- installed as /usr/src/linux-2.6.18-8.1.15.el5 before being able to correctly
- build the driver.
- 
- Please install the kernel sources which must match the running
- linux 2.6.18-8.1.15.el5 kernel, and then try installing again.

* * *

configure: error: Unable to find kernel headers. Failing configure script.

The necessary RPM from Redhat has been installed:

warning: kernel-headers-2.6.18-8.1.15.el5.i386.rpm: Header V3 DSA signature: NOKEY, key ID 37017186  
package kernel-headers-2.6.18-8.1.15.el5 is already installed

Will this driver work on RHEL 5?

You’ll need to install the kernel-devel package for the kernel sources.

Same problem after installing kernel-devel rpm.

I’d recommend opening up a case with Digi Support so we can analyze this more closely. We’ll need a typescript of your compile/install so we can see why this is failing.

Thought I would chime in. I just installed the driver fine on Redhat ES 5.1. The issue is you must add the following DISTRO=REHDAT\_ES\_4 in the rpmbuild line. This info is in the readme.
