I/opt/rpi/sysroot.img/usr/include/c++/8/tr1 will find stdarg.h but -I/usr/include/c++/8/tr1 won't. I was under the assumption -isysroot would change the root for the compiler search paths, but i noticed that's not quite what it does, as providing e.g.
ANDROID NDK UBUNTU ANDROID
If you do not want to do that, I suggest running Android Studio with root privileges to access your NDK directory. I recommend moving your SDK to an new location within the scope of your normal user.
The compiler complains it can't find stdio.h, then stddef.h, etc. /root/Android/Sdk or any other location inside /root/ requires root privileges to access. I then tried ~/Android/Sdk/ndk/061/toolchains/llvm/prebuilt/linux-x86_64/bin/clang \īut hit a sort of lib hell. I extracted the ext4 filesystem from Raspberry OS and monted it onto /opt/rpi/sysroot.img. The specialty using Ubuntu is just because of Linux Origin. I have an x86_64 host that already cross-compiles a C application for android's 4 supported architectures, could I use the existing toolchain to build armeabi-v7a for a Pi (running Linux like Raspbian or whatever)? Working in OS like Ubuntu and Android Eclipse is much easier than working with MS Windows for NDK.
