Harbour+Android(Flutter+Dart) 2025

[alex;]

Hi. That's good news for me. Did I complete it?"Hello from Harbour" in the Flutter window on your Android phone. The gpt-5 project helped me put together, the only thing I don't like allow-multiple-definition in   Makefile 
#Makefile LIBS := $(wildcard c:/harbour_droid/lib/*.a)

libharbour.so:
clang --target=aarch64-linux-androideabi24 -fPIC --sysroot=C:/Android/Sdk/ndk/29.0.13846066/toolchains/llvm/prebuilt/windows-x86_64/sysroot \
-shared \
-o $@ \
-Wl,--whole-archive -Wl,--allow-multiple-definition $(LIBS) -Wl,--no-whole-archive \
-llog -landroid WBR alex;

Excelent.  Alex.

[alex;]

In fact, clang.mk when HB_BUILD_DYN=yes generates the string clang -shared -L../../../../../lib/android/clang --target=aarch64-linux-androideabi24 -o ../../../../../lib/android/clang/libharbour.so @__dyn__.tmp -ldl -lm -llog -Wl,--out-implib,,--output-def,../../../../../lib/android/clang/libharbour.def   

So no need to form libharbour.so additionally.
