我是OpenSplice的新手，并希望从此处编写简单的教程:
https://github.com/PrismTech/dds-tutorial-cpp-ex
我下载了OpenSplice Community Edition，并获取了release.com文件。
然后我克隆了dds-tutorial-cpp-ex git存储库并尝试构建ch1:
$ cd ch1
$ cmake .
$ make

不幸的是，有一个对`org::opensplice::core::DWDeleter::DWDeleter(std::shared_ptr const＆)的 undefined reference 。
库
libdcpsisocpp.so已添加到定义此引用的链接目标(请参阅https://github.com/PrismTech/dds-tutorial-cpp-ex/blob/master/cmake/FindOpenSplice.cmake#L56)。我已经通过更改到
HDE/x86_64.linux/custom_lib文件夹并执行make -f Makefile.Build_DCPS_ISO_Cpp_Lib来完成库的构建，该操作没有错误。为什么会出现此错误？我该如何解决？
我的系统是Ubuntu 14.04 amd64。
OpenSplice版本是:用于x86_64.linux的OpenSplice HDE发行版V6.4.140407OSS，日期2014-04-15
编辑:
OpenSplice OpenSplice HDE版本V6.5.0p1 for x86_64.linux中存在相同的问题，日期为2015-03-19
那里的错误是:
undefined reference to `org::opensplice::core::DRDeleter::DRDeleter(std::shared_ptr<DDS::Subscriber> const&)'
undefined reference to `org::opensplice::core::TopicDeleter::TopicDeleter(std::shared_ptr<DDS::DomainParticipant> const&)'
注意:与(无任何答案)的交叉发布:http://forums.opensplice.org/index.php?/topic/2517-undefined-reference-to-orgopensplicecoredwdeleterdwdeleter/
最佳答案
问题在于所包含的库不是使用C++ 11支持构建的，因此它使用Boost共享指针而不是C++ 11指针，但是本教程代码使用了C++ 11。
编辑Makefile的HDE/x86_64.linux/custom_lib/Makefile.Build_DCPS_ISO_Cpp_Lib并将-std=c++0x添加到CPPFLAGS行可解决此问题。
(别忘了用make -f Makefile.Build_DCPS_ISO_Cpp_Lib重新编译)
@ yasir-majeed感谢您指出这一点!
