在 Linux 主机上针对 Android 目标交叉编译 OpenCV：Cmake 配置期间出现错误

发布于 2025-01-15 10:35:16 字数 16139 浏览 0 评论 0原文

问题描述：

我正在尝试在 Ubuntu 20.04 LTS for Android (aarch64) 上编译具有 OpenCL 支持的 OpenCV 4.5.1（因为库存 OpenCV Android SDK 没有激活 OpenCL 支持）。我很大程度上遵循了本教程涵盖了 OpenCV 的交叉编译。

当尝试配置构建时，Cmake 似乎无法正确创建/定位所有必要的文件夹，从而引发错误（请参阅下面的 cmake 输出）。

我怀疑这可能与 Cmake 难以正确识别 ant 安装有关（如 Cmake 输出中 ant 路径后面缺少的版本号所示）。

我已经通过 Cmake 构建标志设置了 ANT 可执行文件以及 Java 主文件夹的环境变量（请参阅下面的 Cmake 命令）。

查看 Cmake 输出底部的错误消息时，很明显创建必要的 Android 和/或 Java 文件夹存在一些问题。在检查modules/java/android_sdk/CMakeLists.txt（参见下面的摘录）后，我注意到变量OPENCV_JAVA_DIR可能应该在cmake配置的早期阶段设置。但是，当运行下面粘贴的命令时，此变量保持为空，因此 cmake 无法访问文件夹，因为路径不正确。

这些是运行我的 cmake 配置命令时变量的值：

-- OPENCV_JAVA_DIR = /opencv
-- ANDROID_EXECUTABLE = FALSE
-- ANDROID_BUILD_BASE_DIR = 
-- OpenCV_BINARY_DIR= /home/flavio/Downloads/opencv/build_manual

我的 Cmake buildflags 中是否存在一些配置错误或我做错的完全不同的内容？

谢谢你的帮助！

Cmake找不到ant

Cmake无法识别Java

Ant for Java 未显示为已安装，尽管已安装

我已尝试了所有建议的更改，但到目前为止没有成功。重新安装 ant 没有帮助，也没有在 /usr/bin 中的 /usr/share/ant/bin/ant 处创建指向可执行存储的符号链接。

使用的 Cmake 命令（在下载的 opencv 源代码内的 build 文件夹中）：

Problem Description:

I am trying to compile OpenCV 4.5.1 on Ubuntu 20.04 LTS for Android (aarch64) with OpenCL support (since the stock OpenCV Android SDK does not have OpenCL support activated). I largely followed this tutorial covering the cross-compilation of OpenCV.

When trying to configure the build, Cmake seems to be unable to correctly create/locate all the necessary folders and thus throws an error (see cmake output below).

I suspect that it might have something to do with Cmake struggling to recognise the ant installation correctly (as indicated by the missing version number following the ant path in the Cmake output).

I have set the environment variables for the ANT executable as well as the Java Home folder through the Cmake build flags (see Cmake command below).

When looking at the error messages at the bottom of the Cmake output, it becomes clear that there is some problem with creating the necessary Android and/or Java folders. Upon inspection of modules/java/android_sdk/CMakeLists.txt (see extract below) I noticed that the variable OPENCV_JAVA_DIR should probably be set at some earlier stage in the cmake configuration. However, when running my command pasted below, this variable remains empty and hence cmake cannot access the folders since the path is not correct.

These are the values of the variables when running my cmake configuration command:

-- OPENCV_JAVA_DIR = /opencv
-- ANDROID_EXECUTABLE = FALSE
-- ANDROID_BUILD_BASE_DIR = 
-- OpenCV_BINARY_DIR= /home/flavio/Downloads/opencv/build_manual

Is there some configuration error in my Cmake buildflags or something entirely different that I am doing wrong?

Thanks for you help!

I have tried all the proposed changes, so far with no success. Reinstallation of ant did not help, neither creating a symlink to the executable store at /usr/share/ant/bin/ant in /usr/bin.

我遇到了类似的错误，因此我通过打开 -DBUILD_ANDROID_PROJECTS=ON 来修复它，并修复所有不兼容的“SDK TOOL 版本”或“gradle 版本”。然后gradle可以在modules/java/android_sdk/CMakeLists.txt:15中设置所有必要的路径，例如ANDROID_BUILD_BASE_DIR。

例如更新SDK Tools：打开android studio >设置>系统设置> Android SDK > SDK工具>>更新Android SDK构建工具和NDK（并排）

I had similar errors, so I fixed it by turning on -DBUILD_ANDROID_PROJECTS=ON and fix all incompatible "SDK TOOL version" or "gradle versions". Then gradle can set all necessary paths like ANDROID_BUILD_BASE_DIR in modules/java/android_sdk/CMakeLists.txt:15.

For example to update SDK Tools: Open android studio > setting > system settings > Android SDK > SDK Tools > update Android SDK build tools and NDK(side by side)
