From d7a8c4a6a055097a67ccfa3ca7c9ff1b64603a70 Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Tue, 11 Dec 2018 16:31:19 -0300 Subject: perf tools: Add missing open_memstream() prototype for systems lacking it There are systems such as the Android NDK API level 24 has the open_memstream() function but doesn't provide a prototype, adding noise to the build: builtin-timechart.c: In function 'cat_backtrace': builtin-timechart.c:486:2: warning: implicit declaration of function 'open_memstream' [-Wimplicit-function-declaration] FILE *f = open_memstream(&p, &p_len); ^ builtin-timechart.c:486:2: warning: nested extern declaration of 'open_memstream' [-Wnested-externs] builtin-timechart.c:486:12: warning: initialization makes pointer from integer without a cast FILE *f = open_memstream(&p, &p_len); ^ Define a LACKS_OPEN_MEMSTREAM_PROTOTYPE define so that code needing that can get a prototype.
