Thanks Jim, “Make Q=” pointed out my mistake pretty quickly…  the issue was in my unit test code, the reference to the source below is, of course, because it was included by the UT c file.  Just needed a mock.

Hi Paul,

Can you provide more context for the linker failure including complete logs?  Also, prepending with “Q=” will give the full linker line.

Thanks,

Wrt the crypto module https://review.gerrithub.io/c/spdk/spdk/+/403107 I have the need to make a function call to a function that is declared/defined in rte_cryotp.h- a function called rte_crypto_op_free() (see https://doc.dpdk.org/guides/prog_guide/cryptodev_lib.html section 14.4.4<https://doc.dpdk.org/guides/prog_guide/cryptodev_lib.html%20section%2014.4.4>) as I believe I’ve been freeing crypto operation incorrectly and this is potentially the root cause for a data miscompare I get w/65K & >32 qd loads with bdevper and –verify option.

Anyway, I get a linker error (below) even though I have rte_crypto.h included and rte_cryptodev library is properly linked.

/home/peluse/spdk/lib/bdev/crypto/vbdev_crypto.c:420: undefined reference to `rte_crypto_op_free'
collect2: error: ld returned 1 exit status

Also note that I make other calls like rte_crypto_op_pool_create() that is defined in the same file but I have no problems ther.

Am I missing something really, really obvious here?
