From df28bc0836ad6a79cb537ad0b463819738088f3e Mon Sep 17 00:00:00 2001 From: Kay Sievers Date: Mon, 21 Oct 2013 15:24:18 +0200 Subject: build-sys: use -Og instead of -O0 to catch warnings $ touch src/core/dbus.c; make CFLAGS=-O0 make --no-print-directory all-recursive Making all in . CC src/core/libsystemd_core_la-dbus.lo CCLD libsystemd-core.la $ touch src/core/dbus.c; make CFLAGS=-Og make --no-print-directory all-recursive Making all in . CC src/core/libsystemd_core_la-dbus.lo src/core/dbus.c: In function 'init_registered_system_bus': src/core/dbus.c:798:18: warning: 'id' may be used uninitialized in this function [-Wmaybe-uninitialized] dbus_free(id); ^ CCLD libsystemd-core.la -Og Optimize debugging experience. -Og enables optimizations that do not interfere with debugging. It should be the optimization level of choice for the standard edit-compile-debug cycle, offering a reasonable level of optimization while maintaining fast compilation and a good debugging experience. --- src/core/machine-id-setup.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'src/core/machine-id-setup.c') diff --git a/src/core/machine-id-setup.c b/src/core/machine-id-setup.c index 18e015fe7f..1b55da7e56 100644 --- a/src/core/machine-id-setup.c +++ b/src/core/machine-id-setup.c @@ -153,7 +153,7 @@ static int generate(char id[34]) { int machine_id_setup(void) { _cleanup_close_ int fd = -1; int r; - bool writable; + bool writable = false; struct stat st; char id[34]; /* 32 + \n + \0 */ -- cgit v1.2.3-54-g00ecf
