建立专案时，取得来源和目的地必须是不同的错误 [英] Getting source and destination must be different error while building project

问题描述

我在构建项目时遇到此错误.尝试在android-studio中添加新库.基本上有一个主意的人，我正在尝试在这里创建一个新库.

I am getting this error while building project. Trying to add a new library in android-studio. Is there anybody who has an idea basically I am trying to create a new library here.

尝试的选项:

1. 手动删除的版本

1. Manually deleted build

启动/重启缓存

逐步清除构建缓存

构建->清洁项目

但是构建失败.

源C:\ Users \ abc \ AndroidStudioProjects \ Events \ app \ build \ intermediates \ cmake \ debug \ obj \ armeabi-v7a \ libnative-lib.so和目标C:\ Users \ abc \ AndroidStudioProjects \ Events \ app \ build \ intermediates \ cmake \ debug \ obj \ armeabi-v7a \ libnative-lib.so必须不同

Source C:\Users\abc\AndroidStudioProjects\Events\app\build\intermediates\cmake\debug\obj\armeabi-v7a\libnative-lib.so and destination C:\Users\abc\AndroidStudioProjects\Events\app\build\intermediates\cmake\debug\obj\armeabi-v7a\libnative-lib.so must be different

我使用的是同样的CMakeLists.txt:

CMakeLists.txt I am using for the same:

# For more information about using CMake with Android Studio, read the
# documentation: https://d.android.com/studio/projects/add-native-code.html

# Sets the minimum version of CMake required to build the native library.

cmake_minimum_required(VERSION 3.4.1)

# Creates and names a library, sets it as either STATIC
# or SHARED, and provides the relative paths to its source code.
# You can define multiple libraries, and CMake builds them for you.
# Gradle automatically packages shared libraries with your APK.

add_library( # Sets the name of the library.
             native-lib

             # Sets the library as a shared library.
             SHARED

             # Provides a relative path to your source file(s).
             native-lib.cpp
        )

add_library (
        testLib
        SHARED
        TestClassesManager.cpp
)
# Searches for a specified prebuilt library and stores the path as a
# variable. Because CMake includes system libraries in the search path by
# default, you only need to specify the name of the public NDK library
# you want to add. CMake verifies that the library exists before
# completing its build.

find_library( # Sets the name of the path variable.
              log-lib

              # Specifies the name of the NDK library that
              # you want CMake to locate.
              log )

# Specifies libraries CMake should link to your target library. You
# can link multiple libraries, such as libraries you define in this
# build script, prebuilt third-party libraries, or system libraries.


target_link_libraries( # Specifies the target library.
                       native-lib

                       # Links the target library to the log library
                       # included in the NDK.
                       ${log-lib}

        )

target_link_libraries(
        testLib

        native-lib
)

如果我要更换

target_link_libraries(
        testLib

        native-lib
)

通过

target_link_libraries(
        testLib
    ${log-lib}

)

但是我想链接两个库.但这给了上面的错误.请帮忙.

But I want to link both libraries. But it is giving above error. Please help.

推荐答案

这是一个奇怪错误，但感谢您的简洁repro项目.其实有一天有人告诉我，但是我没有运气来重现失败.

This is a weird bug, but thank you for the concise repro project. Actually had someone mention this to me the other day but I hadn't had any luck reproducing the failure.

我仍在调查此处，但是目前看来，一种解决方法是运行干净，然后刷新链接的c ++项目，然后进行构建.如果需要使用刷新链接的c ++项目"按钮，请再次运行clean first .

I'm still investigating here, but for now it seems that a workaround is to run clean, then refresh linked c++ projects, then build. If you need to use the "refresh linked c++ projects" button, again, run clean first.

已修复补丁，将在4.0.1中发布.

A fix has been cherry-picked and will be in 4.0.1.
