src/generate/t_rb_generator.cc: In member function ‘virtual void t_rb_generator::generate_enum(t_enum*)’:

src/generate/t_rb_generator.cc:369:11: error: operands to ?: have different types ‘bool’ and ‘std::basic_ostream<char>’

make[3]: *** [Makefile:749: thrift-t_rb_generator.o] Error 1
make[3]: Leaving directory '/home/dong/thrift-0.9.0/compiler/cpp'

解决

将    first ? first = false : f_types_ << ", ";

修改为

    if(first)
    {
            first = false :
    }
    else
    {
            f_types_ << ", ";
    }
