Some glibc versions mark write() with attribute warn_unused_result (found in Ubuntu 12.04 / eglibc 2.15 / gcc 4.6.3), so we need to silence this warning, especially because we're building with -Werror.

This is a friendly reminder to v2 of the patch (already posted on 2013-11-11), adressing your comments from 2013-11-08, Gilles. I also rebased patch to today's master. The "attribute unused" style was adopted from testsuite/latency/latency.c. We still think fixing the warning in the source code is better than in the configure command line. diff --git a/lib/cobalt/init.c b/lib/cobalt/init.c index 0c2b29a..c3086a9 100644 --- a/lib/cobalt/init.c +++ b/lib/cobalt/init.c @@ -54,7 +54,8 @@ int __rtdm_fd_start = INT_MAX; static void sigill_handler(int sig) { const char m[] = "no Xenomai support in kernel?\n"; - write(2, m, sizeof(m) - 1); + ssize_t rc __attribute__ ((unused)); + rc = write(2, m, sizeof(m) - 1); exit(EXIT_FAILURE); } diff --git a/testsuite/latency/latency.c b/testsuite/latency/latency.c index 6325672..12b90a9 100644 --- a/testsuite/latency/latency.c +++ b/testsuite/latency/latency.c @@ -507,7 +507,7 @@ static void sigdebug(int sig, siginfo_t *si, void *context) case SIGDEBUG_WATCHDOG: n = snprintf(buffer, sizeof(buffer), "%s\n", reason_str[reason]); - write(STDERR_FILENO, buffer, n); + n = write(STDERR_FILENO, buffer, n); exit(EXIT_FAILURE); } -- 1.8.4 _______________________________________________ Xenomai mailing list [email protected] http://www.xenomai.org/mailman/listinfo/xenomai
