[Libguestfs] [PATCH libguestfs 1/8] build: suppress an ignored-write-return-value warning

From: Jim Meyering <meyering(a)redhat.com&gt; * bootstrap (modules): Add ignore-value. * src/guestfs.c: Include "ignore-value.h". (stdout_event): Ignore failure to write to stderr. Also, prefer STDERR_FILENO over the literal "2". * src/Makefile.am (libguestfs_la_CPPFLAGS): Include gnulib's .h files. (libprotocol_la_CFLAGS): Remove -Wall -Wno-unused. --- bootstrap | 1 + src/Makefile.am | 4 +++- src/guestfs.c | 3 ++- 3 files changed, 6 insertions(+), 2 deletions(-) diff --git a/bootstrap b/bootstrap index cea8c40..76e2216 100755 --- a/bootstrap +++ b/bootstrap @@ -53,6 +53,7 @@ modules=' gitlog-to-changelog gnu-make gnumakefile +ignore-value maintainer-makefile manywarnings warnings diff --git a/src/Makefile.am b/src/Makefile.am index 9eb71b9..8d03a77 100644 --- a/src/Makefile.am +++ b/src/Makefile.am @@ -54,7 +54,7 @@ libprotocol_la_SOURCES = \ guestfs_protocol.c \ guestfs_protocol.h -libprotocol_la_CFLAGS = -Wall -Wno-unused +libprotocol_la_CFLAGS = $(BUILT_SOURCES): stamp-generator @@ -117,6 +117,8 @@ libguestfs_la_LIBADD = libprotocol.la libguestfs_la_CFLAGS = -Wall -DGUESTFS_DEFAULT_PATH='"$(libdir)/guestfs"' +libguestfs_la_CPPFLAGS = -I$(top_srcdir)/gnulib/lib + if HAVE_RPCGEN guestfs_protocol.c: guestfs_protocol.x rm -f $@-t $@-t2 diff --git a/src/guestfs.c b/src/guestfs.c index ad3980f..ecdf9e5 100644 --- a/src/guestfs.c +++ b/src/guestfs.c @@ -59,6 +59,7 @@ #include "guestfs.h" #include "guestfs_protocol.h" +#include "ignore-value.h" #ifdef HAVE_GETTEXT #include "gettext.h" @@ -1697,7 +1698,7 @@ stdout_event (struct guestfs_main_loop *ml, guestfs_h *g, void *data, /* In verbose mode, copy all log messages to stderr. */ if (g->verbose) - write (2, buf, n); + ignore_value (write (STDERR_FILENO, buf, n)); /* It's an actual log message, send it upwards if anyone is listening. */ if (g->log_message_cb) -- 1.6.4.378.g88f2f
