Im using such script to build GLib:
❯ cat cross_file_android_arm64_31.txt
[constants]
ndk_path = '/home/ethan/Android/sdk/ndk/ndk'
toolchain = ndk_path / 'toolchains/llvm/prebuilt/linux-x86_64'
[host_machine]

cpu_family = 'aarch64'

c_ld = 'gold'

❯ cat build-android-arm64.sh
GLIB_SRC_DIR="glib-2.78.1"
CROSS_FILE=".gitlab-ci/cross_file_android_arm64_31.txt"
BUILD_DIR="build-release-android-arm64-static"
INSTALL_PREFIX="/mnt/ethan-drive-ntfs/Work/Work/Projects/glib/install"
FULL_INSTALL_PATH="${INSTALL_PREFIX}/${BUILD_DIR}"
cd $GLIB_SRC_DIR
mkdir $BUILD_DIR
meson $BUILD_DIR --default-library=static --cross-file $CROSS_FILE --prefix=$FULL_INSTALL_PATH
meson compile -C $BUILD_DIR
meson install -C $BUILD_DIR
Which build success.
then I use this prebuild lib in my CMake project:

it try to use static libc.a, which I don’t want. It expected to use libc.so.
when i import libc.a manually: ${ANDROID_NDK}/toolchains/llvm/prebuilt/linux-x86_64/sysroot/usr/lib/aarch64-linux-android/libc.a, it build success, but failed to run:
mido:/data/local/tmp # ./l1

where did I wrong?
