我是 OpenSplice 的新手，想从这里开始学习简单教程:
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，存在对`org::opensplice::core::DWDeleter::DWDeleter(std::shared_ptr const&) 的 undefined reference
库 libdcpsisocpp.so 被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)。
我已经通过切换到 HDE/x86_64.linux/custom_lib 文件夹并执行 make -f Makefile.Build_DCPS_ISO_Cpp_Lib 重建了库，没有出现错误。
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 版本为:OpenSplice HDE Release V6.4.140407OSS For x86_64.linux，日期 2014-04-15
编辑: 同样的问题存在于OpenSplice OpenSplice HDE Release V6.5.0p1 For x86_64.linux, Date 2015-03-19
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&)'

最佳答案
问题是所包含的库不是使用 C++11 支持构建的，因此它使用了 Boost 共享指针而不是 C++11 共享指针，但教程代码以某种方式使用了 C++11。
编辑 Makefile HDE/x86_64.linux/custom_lib/Makefile.Build_DCPS_ISO_Cpp_Lib 并将 -std=c++0x 添加到 CPPFLAGS 行解决了问题。
(不要忘记使用 make -f Makefile.Build_DCPS_ISO_Cpp_Lib 重新编译)
@yasir-majeed 感谢您指出这一点!!
关于c++ - 对 org::opensplice::core::DWDeleter::DWDeleter 的 undefined reference ，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/29347056/
