My old slow 32-bit Linux PC is still producing libstdc++-v3... Forgot
to disable multilib which made it still slower:(
While waiting my build arriving into the ligfortran phase, I checked
what would cause
the double definition. There was that :
#ifndef HAVE_STRNDUP
<code>
#endif
wrapper around the redefined function. So investigating why this #define
wasn't set
would be done. In the 'libgfortran/runtime/configure' is the following :
----------- clip ---------------
# Check for library functions.
if test "${hardwire_newlib:-0}" -eq 1; then
# We are being configured with a cross compiler. AC_REPLACE_FUNCS
# may not work correctly, because the compiler may not be able to
# link executables.
$as_echo "#define HAVE_MKSTEMP 1" >>confdefs.h
$as_echo "#define HAVE_STRTOF 1" >>confdefs.h
$as_echo "#define HAVE_SNPRINTF 1" >>confdefs.h
$as_echo "#define HAVE_VSNPRINTF 1" >>confdefs.h
$as_echo "#define HAVE_LOCALTIME_R 1" >>confdefs.h
$as_echo "#define HAVE_GMTIME_R 1" >>confdefs.h
$as_echo "#define HAVE_STRNLEN 1" >>confdefs.h
$as_echo "#define HAVE_STRNDUP 1" >>confdefs.h
----------- clip ---------------
Where that 'hardwire_newlib' will be set I don't know but first
checking whether the generated
'powerpc-eabi/libgfortran/runtime/confdefs.h' or
somewhere else has these '#define's could be done. The problem is there...
