-Werror isn't turned on

[Aamer Akhter]

Hello,

In the process of trying to build ethereal (wireshark now) from the svn trunk I ran into this problem:

wireshark/wiretap$ gcc -DHAVE_CONFIG_H -I. -I. -I.
-I/usr/local/include -I/usr/local/include
"-D_U_=__attribute__((unused))" -Wall -W -g -O2
-I/usr/include/glib-2.0 -I/usr/lib/glib-2.0/include
-I/usr/local/include -I/usr/local/include -MT ascend-grammar.lo -MD
-MP -MF .deps/ascend-grammar.Tpo -c ascend-grammar.c -fPIC -DPIC -o
.libs/ascend-grammar.o
ascend-grammar.c: In function 'ascendparse':
ascend-grammar.c:665: warning: label 'yyerrlab' defined but not used

The ethereal guys are saying this:

-Werror isn't turned on (we don't enable it, as we can't control
OS-supplied or GLib/GTK+/etc.-supplied headers), so the next step would
probably be either "ignore the error" or "report an Ubuntu bug that
Bison's generating code that gets a warning, and then ignore the error".

Discussion is here:

Thanks for your report. This is just a warning and not an error. Is this really an issue. BTW after reading the thread you've mentioned above this was an issue with flex missing and not bison. Can we close this report .

Thanks for your time.

Not reproducible in newer currently supported Ubuntu releases.
