对org :: opensplice :: core :: DWDeleter :: DWDeleter的未定义引用

Question

我是OpenSplice的新手,想从这里编写简单的教程:

https://github.com/PrismTech/dds-tutorial-cpp-ex

我下载了OpenSplice Community Edition并获得了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

make[1]: *** [CMakeFiles/tspub.dir/all] Error 2
make: *** [all] Error 2

不幸的是,有一个未定义的引用`org :: opensplice :: core :: DWDeleter :: DWDeleter(std :: shared_ptr const&)

该库libdcpsisocpp.so将添加到链接目标(请参阅https://github.com/PrismTech/dds-tutorial-cpp-ex/blob/master/cmake/FindOpenSplice.cmake#L56),该目标定义此参考.

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哪个已完成而没有错误来重建库.

为什么我会收到此错误？我该如何解决？

我的系统是Ubuntu 14.04 amd64.

OpenSplice版本是:OpenSplice HDE版本V6.4.140407OSS适用于x86_64.linux,日期2014-04-15

编辑: OpenSplice中存在同样的问题OpenSplice HDE版本V6.5.0p1适用于x86_64.linux,日期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&)'

Answer 1

问题是包含的库不是用C++ 11支持构建的,因此它使用Boost共享指针而不是C++ 11,但教程代码不知何故使用C++ 11.

编辑Makefile HDE/x86_64.linux/custom_lib/Makefile.Build_DCPS_ISO_Cpp_Lib并添加-std=c++0x到CPPFLAGS行修复了问题.

(别忘了重新编译make -f Makefile.Build_DCPS_ISO_Cpp_Lib)

@ yasir-majeed感谢您指出这一点!!
