Subject: [PATCH] libperf: Fix 32-bit build for tests uint64_t printf
Date: Tue, 1 Feb 2022 15:39:03 -0600 [thread overview]
Message-ID: <20220201213903.699656-1-robh@kernel.org> (raw)
Commit a7f3713f6bf2 ("libperf tests: Add test_stat_multiplexing test")
added printf's of 64-bit ints using %lu which doesn't work on 32-bit
builds:
tests/test-evlist.c:529:29: error: format ‘%lu’ expects argument of type \
‘long unsigned int’, but argument 4 has type ‘uint64_t’ {aka ‘long long unsigned int’} [-Werror=format=]
Use PRIu64 instead which works on both 32-bit and 64-bit systems.
Fixes: a7f3713f6bf2 ("libperf tests: Add test_stat_multiplexing test")
