c++ - opencv4tegra : issues compiling sample stereo_match. cpp

Question

我在使用 opencv4tegra 编译标准 opencv 示例时遇到了相当大的困难 - 按照 Jetson TK1 的 nvidia wiki 的指示进行安装。

出于沮丧，我从 2.4.10.1 源代码构建了 opencv，并将其直接安装到/usr/local...并且效果非常好!在我卸载它之后，我在针对他们的编译时遇到了同样的问题，所以显然这是我正在做的事情。有趣的是，我可以针对他们的 opencv4tegra 库运行已编译的示例应用程序，但我无法针对他们的库进行编译。

测试环境:

我没有更改 opencv 2.4.10.1 版本中的示例文件 - 它是相同的stereo_match.cpp 文件。我只是想编译它。

这些函数位于 gpu.hpp 文件内 - 我已经看过了。我也跑过:

nm /usr/lib/libopencv_gpu.so | grep StereoBM_GPU | c++filt

...只是为了确保符号在库中。

这是怎么回事？？所以，它显然没有链接 - 但我无法弄清楚 g++ 想要什么......

请参阅 cmake 指令中的宏以在 opencv 中进行打包，并坚持使用 make。再次感谢您提供线索“Iwillnotexist Idonotexist”。

就我而言，我错过了两个依赖项: /modules/gpu/src/nvidia &&/modules/gpu/src/nvidia/core ...其他部分也提到了“非自由”。

隐藏的依赖项...天哪。

感谢所有贡献的回复 - 现在看起来微不足道。
