[Qemu-devel] Questions about gcc linker errors in crypto sub-directory

[Gonglei (Arei)]

Hi Daniel,

I'm coding cryptodev-vhost-user.c as a new cryptodev backend,
but the gcc report some linker errors:

crypto/cryptodev-vhost-user.o: In function 
`qcrypto_cryptodev_vhost_crypto_cleanup':
/mnt/sdb/gonglei/qemu.git/qemu/crypto/cryptodev-vhost-user.c:87: undefined

Currently I only change the crypto/Makefile.objs:

diff --git a/crypto/Makefile.objs b/crypto/Makefile.objs
index b9ad26a..575f64e 100644
--- a/crypto/Makefile.objs
+++ b/crypto/Makefile.objs

 # Let the userspace emulators avoid linking gnutls/etc
 crypto-aes-obj-y = aes.o

Any others do I need to change? Thanks!
