Re: [PERFORM] Disable-spinlocks while compiling postgres 9.1 for ARM Cortex A8

Hi Tom,

 

I tried to apply the patch. I succeeded in patching configure, configure.in and src/include/pg_config.h.in files.

But while applying the patch for src/include/storage/s_lock.h , I am getting an error.

 

This is how I am doing the patch,

 

Thought of doing the failed patch manually. But couldn’t understand what to do.

 

Please let me know what I am doing wrong and what I should be doing.

 

Thanks and Regards

Jayashankar

Try this patch:

 

BTW, please don't cross-post to multiple PG mailing lists; there's very seldom a good reason to do that.
