SubjectRe: [PATCH v5 2/5] perf report: Find the inline stack for a given address
From
Date
Hi Ravi, Arnaldo,

The build error happens when BFD lib is not set in build environment.

Anyway the patch series should be improved to get better compatibility
for this case. For easy patch management, I send the v6 patch series for
fixing this issue. Very sorry for the inconvenience.

Thanks

Jin Yao
