Errors during creation of package for Android
Hi,
I have Windows-64bit computer. I installed fpcupdeluxe according to Castle’s docs. FPC and Lazarus: stable.
I uninstalled cross platform tools via fpcupdeluxe.
I installed Castle by downloading zip from master of GitHub. And I compiled it with Lazarus. Compiled build tool.
Then I downloaded command line sdk manager. In fact I have MSYS2 thus I installed all needed Android tools with command (taken from docs) using the Unix-way:
sdkmanager --install \
'platform-tools' \
'platforms;android-28' \
'extras;google;google_play_services' \
'build-tools;28.0.3' \
'extras;android;m2repository' \
'ndk-bundle'
I added needed paths to PATH etc.
Then when packaging the examples using:
castle-engine package --os=android --cpu=arm
I am getting the message error listed below. It’s probably complaining about missing:
C:/Programs/adt-bundle-windows-x86/sdk/ndk-bundle/build//…/toolchains/llvm/prebuilt/windows-x86_64/bin/clang++.exe
but in fact in ndk-bundle/build/toolchains/ there is no llvm
So I added ${ANDROID_NDK_HOME}toolchains/llvm/prebuilt/windows/bin/:
to PATH (it was not in docs). But still the problem is the same.

I am getting above’s error when packaging:

before doing it I did as it was advised in docs:
From
android-ndk-XXX/platforms/android-16/arch-arm/usr/lib/copy all the files to<fpcupdeluxe>/cross/lib/arm-android.
Docker is available on latest Windows too, so you can try this option too. It’s requires a little different approach, but in return you have a 100% working environment, where I tested that Android building definitely works, and you don’t need to deal with installing Android SDK/NDK anymore.
