Re: [libvirt] [PATCH 0/3] Couple of build fixes after latest cpu changes

Michal Privoznik <mprivozn(a)redhat.com&gt; [2019-04-15, 06:50AM +0200]: Fixes S390 as well, thanks. I got another incidential build error that doesn't seem related though: ../../examples/domtop/domtop.c: In function 'print_cpu_usage': ../../examples/domtop/domtop.c:242:28: error: 'pos' may be used uninitialized in this function [-Werror=maybe-uninitialized] usage = (now_params[pos].value.ul - then_params[pos].value.ul) / ^ cc1: all warnings being treated as errors GCC is 8.2.1. Here's a patch: diff --git a/examples/domtop/domtop.c b/examples/domtop/domtop.c index c9b51aed..e463e287 100644 --- a/examples/domtop/domtop.c +++ b/examples/domtop/domtop.c @@ -206,7 +206,7 @@ print_cpu_usage(size_t cpu, } for (i = 0; i < ncpus; i++) { - size_t pos; + size_t pos = 0; double usage; /* check if the vCPU is in the maps */
