我正在关注 this在我的 android 项目中使用 C++ 添加 firebase 的教程,我使用的是 CMake 版本 3.10.2 当我运行项目时,出现以下错误:

CMake Error at CMakeLists.txt:52 (target_link_libraries): Cannot
specify link libraries for target "firebase_analytics;firebase_app"
which is not built by this project.
Configuring incomplete, errors occurred!
我的 CMakeLists.txt 文件:
# 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)
# 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.
${log-lib})
# Add Firebase libraries to the target using the function from the SDK.
add_subdirectory(${FIREBASE_CPP_SDK_DIR} bin/ EXCLUDE_FROM_ALL)
# The core Firebase library (firebase_app) is required to use any Firebase product,
# and it must always be listed last.
set(firebase_libs firebase_analytics firebase_app)
target_link_libraries(${target_name} "${firebase_libs}")
最佳答案
这也可能是由于未首先列出您的 图书馆造成的。例如,如果你有这个:
add_library( my_native_code
SHARED
# Other stuff here
)
target_link_libraries(
android)
这将失败:
Cannot specify link libraries for target "android" which is not built by this project.
您需要确保首先列出您的图书馆:
target_link_libraries(
my_native_code
android)
关于android - 无法为不是由该项目构建的目标指定链接库,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/58819864/
