Subject: [RESEND PATCH linux-next 1/2] tools/latency-collector: Check pkg-config install
Date: Fri, 8 Aug 2025 12:05:26 +0800 [thread overview]
Message-ID: <20250808040527.2036023-1-chen.dylane@linux.dev> (raw)
The tool pkg-config used to check libtraceevent and libtracefs, if not
installed, it will report the libs not found, even though they have
already been installed.
Before:
libtraceevent is missing. Please install libtraceevent-dev/libtraceevent-devel
libtracefs is missing. Please install libtracefs-dev/libtracefs-devel
After:
Makefile.config:10: *** Error: pkg-config needed by libtraceevent/libtracefs is missing
on this system, please install it.
Fixes: 9d56c88e5225 ("tools/tracing: Use tools/build makefiles on latency-collector")
