[dpdk-users] Compilation failure with DPDK 18.11.1 (LTS)

[dpdk-users] Compilation failure with DPDK 18.11.1 (LTS)

[adabala, raghuram]

Hello,
  I cannot seem to find the definition of ret_dev_cmp_t in any of the headers I have on my Linux host.
  I have installed the following rpms on my host.
  Could you please help figure out what other rpm(s) I need  ?.
Regards,
Raghu.

dpdk-16.11.8-6.8.1.x86_64
dpdk-kmp-default-16.11.8_k4.4.162_78-6.8.1.x86_64
dpdk-devel-16.11.8-6.8.1.x86_64

Not sure what your problem is, but I can see the definition in rte_dev.h in
official v18.11.1 tag.

v18.11.1:lib/librte_eal/common/include/rte_dev.h:typedef int
(*rte_dev_cmp_t)(const struct rte_device *dev, const void *data);
