【问题描述】：
TL;博士
我在meaning_of_life.c 中有这个 C 函数：
#define FFI_PLUGIN_EXPORT
FFI_PLUGIN_EXPORT int getMeaningOfLife(){
return 42;
}
我尝试使用多种方法将其编译为共享库 (.so)，但是当我尝试在 android 上使用它时，如incompatible target 和file in wrong format 时不断出现错误。你能告诉我正确的方法吗？
我尝试了什么：
- 创建上述C文件
- 创建一个flutter_ffi插件，它会像这样使用它（这在这里有点无关紧要）：
add_library(meaningoflife SHARED IMPORTED ) set_target_properties(meaningoflife PROPERTIES IMPORTED_LOCATION /home/haidar/dev_haidar/c++/meaning_of_life/Src/libLife.so ) target_link_libraries(my_plugin meaningoflife)- 阅读alot，alot... 的文档，并在此处进行了很多搜索，但大多数相关问题和答案都非常古老并且使用旧方法（他们不使用 cmake）
- 创建一个将使用该插件的 Flutter 应用
- 从插件创建一个
.so共享库，首先我在this页面上尝试了该方法（使用NDK编译器和工具链）：
cd /home/haidar/dev_haidar/c++/meaning_of_life/Src comp=/home/haidar/Android/Sdk/ndk/25.1.8937393/toolchains/llvm/prebuilt/linux-x86_64/bin $comp/aarch64-linux-android26-clang -fPIC meaning_of_life.c -o libLife.so -shared // also tried with other compilers as armv7a-linux-androideabi26-clang该库已生成，但是当我使用它时，出现上述错误之一（取决于用于创建它的编译器），例如，这是错误的一部分：

我在 github 上找到了this shell script（这与我在上面的步骤 6 中所做的非常相似），我对其进行了调整以适应我的路径，它成功地为每个架构生成了
.so文件。我创建了一个纯 android 应用程序并从应用程序中调用它，一切正常。add_library(getnumber SHARED IMPORTED) set_target_properties(getnumber PROPERTIES IMPORTED_LOCATION /home/haidar/dev_haidar/c++/getnumber/Src/prebuilt/release/arm64-v8a/libgetnumber.so ) target_link_libraries(imagemagicknativeapp getnumber)一切正常。
当我以完全相同的方式在颤振插件中依赖它时
add_library(getnumber SHARED IMPORTED ) set_target_properties(getnumber PROPERTIES IMPORTED_LOCATION /home/haidar/dev_haidar/flutter/image_magick_ffi/src/Dependencies/ImageMagick/lib/android/arm64-v8a/libgetnumber.so ) target_link_libraries(image_magick_ffi getnumber)我仍然收到错误
ld: error: /home/haidar/dev_haidar/flutter/image_magick_ffi/src/Dependencies/ImageMagick/lib/android/arm64-v8a/libgetnumber.so is incompatible with armelf_linux_eabi我知道问题与编译/链接目标有关 与实际目标（我的手机）不同，但我怎样才能告诉颤振改变这种行为？

从这个[和你之前/删除的（？）问题]，你得到的错误表明如果构建了lib，它是为错误的架构构建的。无论是不是
arm和/或它是为 [松散]arm/linux或arm/standalone而不是arm/android构建的。您必须找到 make 过程正在使用的库的完整路径。如有必要，您可以在strace下运行它，或者在 make 本身中打开一些详细信息。然后，如果您执行file /path/to/my.so，它会告诉您它是为哪个拱门而构建的。您必须确保这与FFI所期望的相同。 -
请注意，您使用
--debug和/或--scan重新运行的构建请求。那么，你做到了吗？ -
@CraigEstey我知道问题是构建库的目标架构错误，但问题是我做错了什么？另外，上面的日志是在我运行颤振应用程序时在 android studio 中使用 -v 标志构建的，我还能将你所说的这些标志放在哪里？
-
@CraigEstey 如果您查看更新的问题，您可以看到我正在正确生成
.so文件，并且对于正确的架构，问题似乎出现在使用颤振插件的颤振应用程序或颤振插件本身 -
如 cmets 在您之前的问题中所述，只需添加资源第三方开源代码，让 CMake 构建它。
