I just pulled the code and found a unused function error ?dump_rxd()? I had to add the ifdef around the function and remove the ifdef inside the function:
#ifdef RTE_LIBRTE_FM10K_DEBUG_RX static inline void dump_rxd(union fm10k_rx_desc *rxd) { RTE_SET_USED(rxd); PMD_RX_LOG(DEBUG, "+----------------|----------------+"); PMD_RX_LOG(DEBUG, "| GLORT | PKT HDR & TYPE |"); PMD_RX_LOG(DEBUG, "| 0x%08x | 0x%08x |", rxd->d.glort, rxd->d.data); PMD_RX_LOG(DEBUG, "+----------------|----------------+"); PMD_RX_LOG(DEBUG, "| VLAN & LEN | STATUS |"); PMD_RX_LOG(DEBUG, "| 0x%08x | 0x%08x |", rxd->d.vlan_len, rxd->d.staterr); PMD_RX_LOG(DEBUG, "+----------------|----------------+"); PMD_RX_LOG(DEBUG, "| RESERVED | RSS_HASH |"); PMD_RX_LOG(DEBUG, "| 0x%08x | 0x%08x |", 0, rxd->d.rss); PMD_RX_LOG(DEBUG, "+----------------|----------------+"); PMD_RX_LOG(DEBUG, "| TIME TAG |"); PMD_RX_LOG(DEBUG, "| 0x%016lx |", rxd->q.timestamp); PMD_RX_LOG(DEBUG, "+----------------|----------------+"); } #endif Also clang on Ubuntu 14.04 does not like the option: CC fm10k_pf.o error: unknown warning option '-Wno-unused-but-set-variable'; did you mean '-Wno-unused-const-variable'? [-Werror,-Wunknown-warning-option]
