Hi,
I’m trying to create a derivation for cross-compiling a CMake based C project for aarch64 Android, and I’ve run into a snag:
Here’s a snippet of my derivation:
with import <nixpkgs> {};
pkgsCross.aarch64-android-prebuilt.stdenv.mkDerivation {
name = "foobarLib";
src = ./foobarLib.tar.gz;
buildInputs = [
python3
rsync
];
nativeBuildInputs = [
cmake
];
...
}
The package builds just fine without the cross-compiling toolchain (just stdenv.mkDerivation), but when I try to build with nix-build ./foobar.nix, I get the following. Any good leads as to what may be wrong?
these derivations will be built:
/nix/store/8kzgpqgc7mhwgdzs5wb7pf2qv12ds1q4-foobarLib-aarch64-unknown-linux-android.drv
