Example: $ make defconfig T=x86_64-native-linux-gcc O=master $ make EXTRA_CFLAGS='--coverage' O=master [...] CC rte_flow.o rte_flow_dynf_metadata_offs is not flagged as experimental but is listed in version map Please add __rte_experimental to the definition of rte_flow_dynf_metadata_offs $ objdump -t master/build/lib/librte_ethdev/rte_flow.o |grep _offs$ 0000000000000000 l F .text.startup 000000000000000a _GLOBAL__sub_I_65535_0_rte_flow_dynf_metadata_offs 0000000000000620 g O .data 0000000000000004 rte_flow_dynf_metadata_offs Protect against this by adding a space character in the pattern.
