1.4.17: -Werror and "comparison between signed and unsigned integer expressions" #353

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago
configure.ac from memcached 1.4.17 adds -Werror to CFLAGS, when the compiler is 
GCC.  This breaks the build with (GCC) 4.8.3 20131226 (prerelease), as it 
reports the following warnings.  In config.site I set

export CFLAGS='-pipe -O3 -flto -Wl,-S -Wl,--hash-style=gnu -Wl,-O1 -Wl,-z,relro 
-Wall -Wextra'

so the effective compiler flags are -Wextra -Werror:

Holy crap....

I don't see how Werror got turned on though? It doesn't appear to be in the 
commits for configure.ac anytime recently.

Or are you saying *you* did that and got all this?

I'd like to spend some time cleaning up warnings, but this is a bit much for 
now. I need the buildbots up before being able to reliably make those sorts of 
changes anyway.
