perf namespaces: Avoid get_current_dir_name dependency

2025-10-03T18:28:04+00:00

get_current_dir_name is a GNU extension not supported on, for example, Android. There is only one use of it so let's just switch to getcwd to avoid build and other complexity.

perf tools: Fixup get_current_dir_name() compilation

2021-08-30T13:06:16+00:00

strdup() prototype doesn't live in stdlib.h . Add limits.h for PATH_MAX definition as well. This fixes the build on Android.

perf tools: Move get_current_dir_name() cond prototype out of util.h

2019-07-09T13:13:26+00:00

And in a separate header, so that we erode util.h a bit more. Cc: Adrian Hunter Cc: Jiri Olsa Cc: Namhyung Kim Link: https://lkml.kernel.org/n/tip-xpzvuu9d0gei9jl9bkzgobln@git.kernel.org Signed-off-by: Arnaldo Carvalho de Melo

tools build feature: Check if get_current_dir_name() is available

2018-11-19T20:12:17+00:00

As the namespace support code will use this, which is not available in some non _GNU_SOURCE libraries such as Android's bionic used in my container build tests (r12b and r15c at the moment).
