 *   CONFIG_CRYPTO_CBC:  is not set when it should be.
 * Please check to make sure these options are set correctly.
 * Failure to do so may cause unexpected problems.


shouldn't "CONFIG_CRYPTO_CBC" rather be "CONFIG_CRYPTO_CRC"?

I doubt it:  

  | Symbol: CRYPTO_CBC [=m]                                                 
  │ Prompt: CBC support                                                     │

There is no CRYPTO_CRC, the closest thing is CRYPTO_CRC32C, so I believe it is correct how it is.

There is a bug if you are getting that message for that kernel version though.  CRYPTO_CBC was added for 2.6.19

Comment 3 Alexander Jenisch 2007-03-30 06:27:46 UTC

well the error (naturally) disappeart, after i upgraded to 2.6.20, but i suppose it's still there with kernels < 2.6.19.

CBC stands for cypher block chaining and is in itself "correct". kdepim doesn't deal with the kernel, so this message has nothing to do with kdepim. You may get such a message on a kernel module build or some else application that directly interacts with the kernel...

Anyways: It's a matter of _yours_ configuring your kernel correctly. Nothing that can be expressed via dependencies or the like. The check exists more or less for pure convenience, so you know what you have to fix. Not a bug.
