Hi Guido,

 

Thanks for committing the fix. There is one more, minor issue. I get a few warnings when using Gecode headers with a high warning level:

 

  gecode/set.hh:1278: warning: comma at end of enumerator list

  gecode/float.hh:1653: warning: comma at end of enumerator list

 

Trailing commas in enums were only added in C++11 and, although most C++ compilers support them as an extension, I think it would be nice if headers didn't rely on extensions. The attached patch fixes the warnings.

 

Cheers,

Victor

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
