------- Comment #7 from hunor at cs dot bme dot hu 2008-02-11 17:50 -------
I got the same error on i686-pc-linux-gnu with revision 132237. The -Werror is
indeed the result of --enable-maintainer-mode:
libstdc++-v3/acinclude.m4:
...
if test x"$USE_MAINTAINER_MODE" = xno; then
WERROR=''
else
WERROR='-Werror'
fi
...
libstdc++-v3/fragment.am:
...
WARN_CXXFLAGS = \
$(WARN_FLAGS) $(WERROR) -fdiagnostics-show-location=once
...
libstdc++-v3/src/Makefile.am:
...
AM_CXXFLAGS = \
-fno-implicit-templates \
$(WARN_CXXFLAGS) \
$(OPTIMIZE_CXXFLAGS) \
$(CONFIG_CXXFLAGS)
...
libstdc++-v3/libsupc++/Makefile.am:
...
AM_CXXFLAGS = \
-fno-implicit-templates \
$(LIBSUPCXX_PICFLAGS) \
$(WARN_CXXFLAGS) \
$(OPTIMIZE_CXXFLAGS) \
$(CONFIG_CXXFLAGS)
...
Otherwise, the warning is correct:
gcc/unwind-pe.h:
...
static unsigned int
size_of_encoded_value (unsigned char encoding)
...
is indeed unused in libstdc++-v3/libsupc++/eh_call.cc. It should be static
inline or __attribute__((unused)), or alternatively
libstdc++-v3/libsupc++/eh_call.cc could define NO_SIZE_OF_ENCODED_VALUE before
including the header.
