生成dds-tutorial-cpp-xml时找不到OpenSpliceConfig.cmake或opensplice-

Question

我正在努力学习dds。根据教程，附录1建议查看github中提供的名为dds-examples-cpp-ex的示例。

根据自述文件构建此示例的简单命令是cmake . && make

我执行命令

cmake . && make

在我的本地机器上克隆后，从该文件夹的cmake目录

我得到以下错误：

CMake Error at CMakeLists.txt:28 (FIND_PACKAGE):
By not providing "FindOpenSplice.cmake" in CMAKE_MODULE_PATH this project
has asked CMake to find a package configuration file provided by
"OpenSplice", but CMake did not find one.
Could not find a package configuration file provided by "OpenSplice" with
any of the following names:
OpenSpliceConfig.cmake
opensplice-config.cmake
Add the installation prefix of "OpenSplice" to CMAKE_PREFIX_PATH or set
"OpenSplice_DIR" to a directory containing one of the above files.  If
"OpenSplice" provides a separate development package or SDK, be sure it has
been installed.

-- Configuring incomplete, errors occurred!

我试图找到OpenSpliceConfig.cmake&amp；opensplice-config.cmake在我的系统上，但我没有得到任何结果。

我的问题是如何更正路径或修复此错误？

我在本地机器上运行了OpenSplice，并直接从$OSPL_HOME/opensplice/dcps/Tutorial执行了其他示例。它们工作得很好。

我还尝试构建ch1。我从编辑了ch1/CMakeLists.txt中的第二行

set(CMAKE_MODULE_PATH ../cmake)

至

set(CMAKE_MODULE_PATH ${CMAKE_CURRENT_SOURCE_DIR}/../cmake)

以便能够在CCD_ 7所在的根目录中找到cmake文件夹。

当我执行以下操作时，我遇到了同样的问题：

cd ch1 && mkdir build && cd build && cmake ..
CMake Error at /home/gajendra/Documents/AnokhiDocs/DDS/dds-tutorial-cpp-ex/cmake/FindOpenSplice.cmake:72 (MESSAGE):Could not find OpenSplice DDS

Answer 1

我在Ubuntu 20.04和OpenSplice 6.10.3p1 上遇到了同样的问题

我只是在安装目录中找到了release.com文件，然后转到每个"；ch"；按照@Tsyvarev建议的文件夹，并从那里运行cmake . && make。

CMake随后成功运行。
