What about "fpcupdelux" ??

You can try to produce    CPU/aarch64 <-->  OS/android ]   cross
compile ....

Please state your error in more detail.
I just used fpcupdeluxe to install a cross-compiler for linux-aarch64
with 100% success on trunk.

OK. Today I'll come back from work and then I'll attach a photo of the
screen.

FPC does not support aarch64-android.
FPC does support aarch64-linux.

good afternoon. means, if I compile the library under aarch64-linux
then it will work under arm64 android?

AFAIK nope.
Android's C runtime (bionic) is not binary compatible with the linux
GNU libc.

You can then prompt as in apk written in the android studio download
the library arm under the system arm64?

aarch64 and x86_64 CPUs are not supported for the android target yet.
I plan implement it soon.

32-bit libraries are transparently loaded and work even on 64 bit
android. But an application's apk must not contain any 64-bit libs.
This will change soon and newer version of android will require 64-bit
libs on 64-bit android. That's why it is needed to add support for
64-bit android in FPC as soon as possible.

Late to the party but I have the same question about 64bit libs.

1. Is it a requirement now?
2. Which branches of FPC support it beside trunk?

I think Google announced recently that they won't support ARM 32-bit
anymore, so I'd say that more or less, yes, they're a requirement now.

FPC 3.2 is the first release that supports aarch64-android.
