安装bedtool,在make时报错

在github上下载了最新版的bedtool，在make时报错，报错内容如下：

src/utils/BamTools/include/BamAlignment.mapping.hpp: In member function ‘bam1_t* BamTools::BamAlignment::_Bin_t::_ptr() const’:
src/utils/BamTools/include/BamAlignment.mapping.hpp:10:92: warning: invalid access to non-static data member ‘BamTools::BamAlignment::Bin’  of NULL object [-Winvalid-offsetof]
            return ((BamAlignment*)(((uintptr_t)this) - ((uintptr_t)&((BamAlignment*)NULL)->Bin)))->HtsObj2();
                                                                                            ^
src/utils/BamTools/include/BamAlignment.mapping.hpp:10:92: warning: (perhaps the ‘offsetof’ macro was used incorrectly) [-Winvalid-offsetof]

本人编程基础较差，求问各位们具体应如何解决该问题？

你用的什么系统，什么平台编译？
