我不能建mlpack吗？

Question

我正在开发mlpack库(C++机器学习库)。我在这里遵循了keon的步骤：构建mlpack，但是当我到达最后一步，即构建mlpack时，在cmd中得到了以下错误：

CMake Warning (dev) at CMakeLists.txt:51 (if):
Policy CMP0054 is not set: Only interpret if() arguments as variables or
keywords when unquoted. Run "cmake --help-policy CMP0054" for policy
details. Use the cmake_policy command to set the policy and suppress this
warning.

Quoted variables like "MSVC" will no longer be dereferenced when the policy
is set to NEW. Since the policy is not set the OLD behavior will be used.
This warning is for project developers. Use -Wno-dev to suppress it.

Answer 1

你一定是搞砸了你的鲤鱼的安装，更确切地说，你并没有指定包括脏在内的鲤鱼。

根据这更详细的说明，第10点：

指定库的路径、dll和设置一些定义，详细信息可以在这里找到。

因此，您可以尝试将这些行添加到mlpack的CMakeLists.txt中：

set(ARMADILLO_LIBRARY "C:/Users/yyyy/Qt/3rdLibs/armadillo/armadillo-5.600.2/vc2015_build/bin/vc2015_x86_amd64/release") set(ARMADILLO_INCLUDE_DIR "C:/Users/yyyy/Qt/3rdLibs/armadillo/armadillo-5.600.2/include")
