Subject: [RFC PATCH] selftest/powerpc: Add rule file to address sub-folder test fail
Date: Sun, 25 Feb 2024 22:09:26 +0530 [thread overview]
Message-ID: <20240225163926.264286-1-maddy@linux.ibm.com> (raw)
When running `make -C powerpc/pmu run_tests` from top level selftests
directory, currently this error is being reported
make: Entering directory '/home/maddy/linux/tools/testing/selftests/powerpc/pmu'
Makefile:40: warning: overriding recipe for target 'emit_tests'
../../lib.mk:111: warning: ignoring old recipe for target 'emit_tests'
gcc -m64 count_instructions.c ../harness.c event.c lib.c ../utils.c loop.S -o /home/maddy/selftest_output//count_instructions
In file included from count_instructions.c:13:
event.h:12:10: fatal error: utils.h: No such file or directory
12 | #include "utils.h"
| ^~~~~~~~~
compilation terminated.
This is due to missing of include path in CFLAGS. That is, CFLAGS and
GIT_VERSION macros are defined in the powerpc/ folder Makefile which
in this case not involved.
To address the failure incase of executing specific sub-folder test directly,
a new rule file has been addded by the patch called "include.mk" under
selftest/powerpc/ folder and is linked to all Makefile of powerpc/pmu
sub-folders.
