GCC 6 support

[psturm]

I am trying to build the grsecurity-patched 4.3.3 kernel using the latest GCC 6 weekly snapshot. I get the error message that my compiler does not support plugins. I ran the plugin.sh and here is the output. Any idea what I need to do?

Code: Select all

bash-4.3# sh -x scripts/gcc-plugin.sh g++ g++ gcc
++ dirname scripts/gcc-plugin.sh
+ srctree=scripts
++ gcc -print-file-name=plugin
+ gccplugins_dir=/usr/lib/gcc/x86_64-pc-linux-gnu/6.0.0/plugin
++ g++ -E -x c++ - -o /dev/null -Iscripts/../tools/gcc -I/usr/lib/gcc/x86_64-pc-linux-gnu/6.0.0/plugin/include
+ plugincc='<stdin>:3:2: warning: #warning g++ CXX [-Wcpp]'
+ '[' 0 -ne 0 ']'
+ case "$plugincc" in
++ g++ -c -x c++ -std=gnu++98 - -fsyntax-only -Iscripts/../tools/gcc -I/usr/lib/gcc/x86_64-pc-linux-gnu/6.0.0/plugin/include

hmm, looks like i forgot to release some of the gcc 6 fixes for gcc-common.h, will be in the next patch. btw, you no longer need to run the script by hand, on error the makefile should rerun it for you with the output visible on stderr.

I just tried the patch posted on 3/3/2016 and it still failed. Same message about plugins not being supported.

that'd be because *i* didn't release my next patch at the time but it's out now and will soon be in grsec.
