Now I'm having problems while running $make all-gold

Here is the error message:

cc1plus: warnings being treated as errors

In file included from ../../src/gold/_expression_.cc:33:

This is my bison version: 

bison (GNU Bison) 2.5

I've searched at google but found nothing else.

Any suggestions? 

Thanks,

Hi, 

I'm having trouble using the whole-program analysis features.

When I try to run the

$clang -flto -use-gold-plugin -fmemsafety -o file file1.o file2.o ... -L$PREFIX/lib

command, it gives me the following error message:

/usr/bin/ld: unrecognized option '-plugin'

/usr/bin/ld: use the --help option for usage information

clang: error: linker command failed with exit code 1 (use -v to see invocation)

(Yes I am changing the parameters)

I'm assuming you're on Linux.  Is this correct?

I also checked the clang man page and didn't find any reference to this option.

Am I missing something on the installation?

Yes.  You need to install the Gold linker; some Linux systems come with an older version of ld that isn't based on Gold and, therefore, cannot use the LLVM/SAFECode libLTO plugins.

Directions on compiling and installing these can be found in the LLVM Gold Plugin document at http://llvm.org/docs/GoldPlugin.html.
