+Subject: [PATCH] compile: Remove -Werror and avoid build failures because of
+ warnings
+
+Using -Werror on production is a bad idea, as otherwise harmless warnings
+get treated as errors breaking builds. This is currently the case with
+Nios-II architecture toolchain, warning about a deprecated macro:
+
+../usr/nios2-buildroot-linux-gnu/sysroot/usr/include/features.h:148:3:
+error: #warning "_BSD_SOURCE and _SVID_SOURCE are deprecated, use _DEFAULT_SOURCE" [-Werror=cpp]
+ # warning "_BSD_SOURCE and _SVID_SOURCE are deprecated, use _DEFAULT_SOURCE"
+
+Instead of trying to fix the macro, let's fix the real issue here,
+and remove -Werror.

But which is the real problem: the BSD_SOURCE macro usage or the warning in the toolchain?

Other architectures are not producing any warning, so this sounds like yet another issue with the toolchain.

PATCH 1/1 zlog: Add patch to remove -Werror

The BSD_SOURCE macro usage.

Quoted 2 lines

Other architectures are not producing any warning, so this sounds like yet another issue with the toolchain.

That's because NIOS II is for now the only toolchain using glibc 2.20, which has deprecated certain macros. Packages should be converted, as such warnings will also appear with other toolchain as they start using glibc 2.20.

See commit 116733c6c211f49d7ba5fff5883f682eb72106a3 for instance.

Best regards,

Thomas

Great, thanks. I hadn't noticed you fixed a similar thing before.
