[gecode-users] Fwd: error when compiling Gecode with clang and -std=c++11

[victor.zverovich at gmail.com]

Hi,

Sending this email again for it apparently hasn't come through last time.

There is an error when compiling Gecode in debug mode with clang and
-std=c++11 (I compile Gecode as a part of another project, so I don't use
the default flags):

gecode/flatzinc/flatzinc.cpp:280:34: error: comparison between pointer and
integer ('SharedHandle::Object *' and 'int')
    (__builtin_expect(!(object() == false), 0) ? __assert_rtn(__func__,
"gecode/flatzinc/flatzinc.cpp", 280, "object() == false") : (void)0);
                        ~~~~~~~~ ^  ~~~~~


This can be reproduced by compiling Gecode with the following commands:

CXX=clang++ CXXFLAGS=-std=c++11 ./configure --enable-debug
make


The attached patch fixes the error.

Best regards,
Victor
