c++ - 如何在linux下基于caffe编译cpp

Question

我得到了一个关于 Visualize-features 函数的 cpp。我想编译它，但有一些错误。我将 Visualize_features.cpp 移动到 CAFFE_ROOT/build/tools/并使用以下命令:外壳命令:

    g++ -v visualize_features.cpp -o visualize_features

visualize_feature.cpp:

Answer 1

由于您的源代码存在于 caffe-master 的 tools 文件夹中，因此您可以通过执行 caffe 的常规 make 命令来创建可执行文件，并且名为 visualize_features.bin 的可执行文件应存在于 build/tools 文件夹中。这对您来说是最简单的方法。

您当前使用的构建命令非常不完整，没有提到各种依赖项的包含文件夹和各种库的路径。我认为您必须学习如何编写 Makefile。
