From 096972f5588dbac741f7f0cc057c84d895d4d80f Mon Sep 17 00:00:00 2001 From: Rob Herring Date: Tue, 1 Feb 2022 15:39:03 -0600 Subject: [PATCH] libperf: Fix 32-bit build for tests uint64_t printf MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Commit a7f3713f6bf207e6 ("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.
