I pulled down the latest code in svn. I enabled the checking in the configure.ac
file:
# Disabled for now until all platforms are clean
# carll enabled
format_checking_enabled=yes
if test "$format_checking_enabled" = "yes"; then
AC_GCC_WARNING_SUBST([format-signedness], [FLAG_W_FORMAT_SIGNEDNESS])
else
dumy_assignment_to_avoid_syntax_errors=1
AC_SUBST([FLAG_W_FORMAT_SIGNEDNESS], [])
fi
I ran .configure and make. I captured the output from make and looked through it but
didn't find any errors related to the checking. The system I ran on was:
Power 8 Little Endian
Linux 3.13.0-35-generic #62-Ubuntu SMP Fri Aug 15 01:57:29 UTC 2014 ppc64le GNU/Linux
gcc (Ubuntu 4.8.4-2ubuntu1~14.04) 4.8.4
I tried again with the latest GCC I can find which is available via the IBM advanced
tool chain.
gcc (GCC) 5.1.1 20150512
Again, I didn't find any error messages in the output from make.
Let me know if I am looking in the right place or didn't set things up correctly.
