在 Linux 上安装 OSVR - 设置二进制目录

Question

我目前正在尝试安装 OSVR-Core on my Debian 9.1 system. I installed all the prerequisites and followed this 教程。现在我坚持做这个项目。我创建了一个构建目录并尝试运行

cmake -DCMAKE_PREFIX_PATH="/usr/local/stow/libfunctionality" ~/src/OSVR-Core

但我得到错误，我的二进制目录应该与我的源目录不同。我的源目录（带有 make 文件）应该是 ~/src/OSVR-Core 并且因为我在 ~/src/OSVR-Core/build 中，所以我认为这就足够了。

如何（以及在哪里）更改二进制目录的位置？我尝试了命令行选项 -D CMAKE_BINARY_DIR= "path/to/OSVR-Core/build 但没有用。我在网上看到，你不应该手动设置二进制目录，而是 created/calculated.

这是 CMakeError.log 文件：

Answer 1

你用过

cmake .. -DJSONCPP_WITH_CMAKE_PACKAGE=ON -DJSONCPP_LIB_BUILD_SHARED=OFF -DCMAKE_CXX_FLAGS=-fPIC

因为这就是教程所说的用于构建项目的内容，并且 CMakaList.txt 将处理所有路径。

Answer 2

我设法让它工作了。我在 ~/src 目录中重新安装了 libfunctionality。然后我删除了 OSVR-core 的 github 存储库并再次克隆它。之后它起作用了，使用：

$ cmake .. -DJSONCPP_WITH_CMAKE_PACKAGE=ON -DJSONCPP_LIB_BUILD_SHARED=OFF -DCMAKE_CXX_FLAGS=-fPIC $ make
