Subject: examples/vhost_scsi: disable build if missing dependency
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=8d47a753b7cb05e0ef62360324c6a28505038d09;p=dpdk.git

examples/vhost_scsi: disable build if missing dependency

The vhost_scsi example code is set to build, even if the requisite header
file virtio_scsi.h isn't available.  This happens on some Ubuntu systems
when some versions of the libc-dev package aren't available.

Check whether the virtio_scsi.h file exists, and if not, set the build
flag to false.
