From 9ae6d4935e3df35a23bbbe531c6b9ff314e7fd0f Mon Sep 17 00:00:00 2001 From: Thomas Huth Date: Tue, 29 Sep 2015 17:45:28 +0200 Subject: [PATCH] testptp: Silence compiler warnings on ppc64 MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit When compiling Documentation/ptp/testptp.c the following compiler warnings are printed out: Documentation/ptp/testptp.c: In function ‘main’: Documentation/ptp/testptp.c:367:11: warning: format ‘%lld’ expects argument of type ‘long long int’, but argument 3 has type ‘__s64’ [-Wformat=] event.t.sec, event.t.nsec); ^ Documentation/ptp/testptp.c:505:5: warning: format ‘%lld’ expects argument of type ‘long long int’, but argument 2 has type ‘__s64’ [-Wformat=] (pct+2*i)->sec, (pct+2*i)->nsec); ^ Documentation/ptp/testptp.c:507:5: warning: format ‘%lld’ expects argument of type ‘long long int’, but argument 2 has type ‘__s64’ [-Wformat=] (pct+2*i+1)->sec, (pct+2*i+1)->nsec); ^ Documentation/ptp/testptp.c:509:5: warning: format ‘%lld’ expects argument of type ‘long long int’, but argument 2 has type ‘__s64’ [-Wformat=] (pct+2*i+2)->sec, (pct+2*i+2)->nsec); This happens because __s64 is by default defined as "long" on ppc64, not as "long long". However, to fix these warnings, it's possible to define the __SANE_USERSPACE_TYPES__ so that __s64 gets defined to "long long" on ppc64, too.
