https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D240398 --- Comment #1 from Jan Beich <jbeich@FreeBSD.org> --- Real world example from a library bundled with Firefox: $ git clone https://github.com/kinetiknz/cubeb $ cd cubeb $ CFLAGS=3D"-isystem/usr/local/include" LDFLAGS=3D"-L/usr/local/lib" cmake . $ make [...] src/cubeb_alsa.c:564:9: warning: implicitly declaring library function 'snprintf' with type 'int (char *, unsigned long, const char *, ...)' [-Wimplicit-function-declaration] r =3D snprintf(node_name, sizeof(node_name), "pcm.%s", string); ^ $ fgrep XOPEN src/cubeb_alsa.c #define _XOPEN_SOURCE 500 I cannot fix the warning upstream because neither Linux nor other BSDs are affected. --=20 You are receiving this mail because: You are the assignee for the bug.=
