[Lustre-discuss] kernel-2.6.18-8.1.14 + lustre 1.6.4.2 + OFED 1.2

[Charles Taylor]

We seemed to have it a stumbling block when building with the above  
(supported) versions.    Our process...

1. Start with stock rhel5 2.6.18-8.1.14 source tree
2. Configure InfiniBand support out of the the kernel (we will build  
OFED separately).
3. Apply the 1.6.4.2 kernel patches to the kernel source.
4. Build the kernel.
5. Build OFED 1.2 against the patched kernel
6. Build Lustre using the patched Kernel+OFED 1.2

This worked fine for 1.6.3 but for 1.6.4.2, after patching the kernel  
and trying to build OFED 1.2, we get the error below.    Now, we find  
references to this problem all over the place but nothing specific to  
building lustre.   Since Lustre 1.6.4.2 is supposed to support OFED  
1.2, it seems that OFED should build against a kernel patched for  
lustre 1.6.4.2 but apparently it does not.    If we use the un- 
patched kernel (i.e. do not apply the lustre 1.6.4.2 kernel patches  
to it), OFED 1.2 builds without a problem.    We are looking for an  
easy #define way out of this hole right now but if there is a known   
solution to this, we would love to know about it.

If there is a better way to do this, we are open to that as well.

Thanks,
