android 应用程序开发与 ndk 和 tcc 可能吗？

如何解决android 应用程序开发与 ndk 和 tcc 可能吗？

是否可以在 tcc（微型 C 编译器）的帮助下创建 Android 应用程序？

对我来说，普通的 ndk APK 看起来很简单。 /meta-inf文件夹下只有一些签名，/lib、AndroidManifest.xml和resources.arsc下的动态*.so库。

├───lib
│   └───x86
│       └───gdbserver
│       └───libAndroid1.so
├───meta-inf
│   └───CERT.RSA
│   └───CERT.SF
│   └───MANIFEST.MF
├───AndroidManifest.xml
├───resources.arsc

而且，似乎 gcc/clang 编译器可以被 tcc 替换。我设法用命令编译了一个通用的 *.so 文件：

tcc -r dllmain.c -o dllmain.o
tcc -shared dllmain.o -o dll.so

但现在我不确定，我将如何通过用 tcc 替换 gcc/clang 来编译一个完整的 ndk 项目。

这是我失败的尝试：

C:\Users\gray\source\repos\Android1\Android1\Android1.NativeActivity>tcc -shared -r main.c -o libAndroid1.so -IC:\Microsoft\AndroidNDK\android-ndk-r15c\platforms\android-19\arch-x86\usr\include\
tcc: warning: -r: overriding compiler action already specified

此外，我将 main.cpp 重命名为 main.c 以使其与 tcc 一起使用。 ma​​in.c：
