Hi,
I'm currently working on the KLEE tool that uses LLVM (2.9 because
that's
what KLEE currently uses) and in particular I'm having an unexpected
problem with the llvm::cl::bits class. I try something like this...
enum testx
{
A,B
};
cl::bits<testx> queryLoggingOptions("option",cl::values(
clEnumVal(A,"this is a"),
clEnumVal(B,"this is b"),
clEnumValEnd
)
);
And when I compile (gcc 4.7.1 20120721 (prerelease) ) I get an error like
this...

I think this is related to "Name Look up Change" in
http://gcc.gnu.org/gcc-4.7/porting_to.html . Indeed if I modify LLVM 2.9's
header file to use ``this->addValue()'' instead of
``addValue()'' I can
than successfully compile.
Is there anyway round this because I don't really want to have to patch
LLVM's header files specially for KLEE. I took a look at the latest LLVM
code (
https://github.com/llvm-mirror/llvm/blob/master/include/llvm/Support/CommandLine.h#1512
)
and the line that's causing me compile problems doesn't seem to have
changed. Does that mean that no one else has had the problem or am I doing
something very wrong?
Regards,
Dan Liew.
