无法构建surround360_render - CMake问题

Question

后台我正在Kubuntu16.04.04LTS上运行，这是一个新的安装。我试图基于以下代码和说明构建surround360_render：render

• 除了python，numpy，pip之外，我遵循了说明。我不需要蟒蛇。
• 根据这里的说明安装here，而不是在ceres git页面上安装。
• 安装llvm，Halide使用加速ISP

在制作...360_render时，我得到了以下错误：

我到目前为止尝试过的

• 我试图实现https://github.com/facebook/Surround360/issues/253失败。我收到以下信息： 98%生成目标folly_dep.cpp扫描依赖关系，98%生成CXX对象CMakeFiles/folly.dir/ folly _dep.cpp.o 99%链接CXX共享库libfolly.so /usr/bin/ld:在创建共享对象时不能使用针对`.rodata的libfolly.so重新定位R_X86_64_32‘；使用CMakeFiles/folly_base.dir/folly/ClockGettimeWrappers.cpp.o:错误重新编译，添加符号:坏值collect2:错误: ld返回1个退出状态CMakeFiles/folly.dir/build.make:514:目标' libfolly.so‘失败make2的配方：*libfolly.so错误1 CMakeFiles/Makefile2:180:目标' CMakeFiles/folly.dir/all’failed make1：*CMakeFiles/folly.dir/all Error 2 Makefile 2 Makefile:127
• 假设apt安装的标准双转换-dev库存在问题，我使用以下说明卸载该库，重新编译双转换： git克隆https://github.com/google/double-conversion.git cd双转换cmake -DBUILD_SHARED_LIBS=ON .使-j $(nproc) sudo
• 重建的愚蠢之处如下： $ cmake配置..。$ make -j $(nproc)

没起作用。重做cmake & make

    $ cmake configure "-DCMAKE_INCLUDE_PATH=$HOME/bin/fb-lib/double-conversion/build/include" "-DCMAKE_LIBRARY_PATH=$HOME/bin/fb-lib/double-conversion/build//lib" ..
    $ make -j $(nproc)

我得到以下错误：

    CMake Error at CMakeLists.txt:201 (find_package):
        Could not find a package configuration file provided by "double-conversion"
        with any of the following names:

        double-conversionConfig.cmake
        double-conversion-config.cmake

    Add the installation prefix of "double-conversion" to CMAKE_PREFIX_PATH or
    set "double-conversion_DIR" to a directory containing one of the above
    files.  If "double-conversion" provides a separate development package or
    SDK, be sure it has been installed.

Answer 1

这些问题是因为“双转换”没有作为一个库包括在surround360_render的各个模块中。要解决这个问题，在目录CMakeLists.txt下修改surround360_render，如下所示：

添加：

双转换

到失败的各个模块的TARGET_LINK_LIBRARIES部分。在我的例子中，失败的模块是: TestRenderStereoPanorama、TestHyperPreview、TestPoleRemoval、TestColorCalibration、TestVignettingCalibration、TestVignettingDataAcquisition和GeometricCalibration。

我列出这些的原因是，有比这些模块更多的模块，这就是为什么我们不需要添加双转换作为默认库来链接。

把这个放在这里以防别人遇到类似的问题。
