Bug ID: 440709
Summary: Broken Craft ARM cross compilation on Android Docker
environment
Product: Craft
Version: unspecified
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: Core
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected]
Target Milestone: ---
SUMMARY
Attempts to cross compile ARM and ARM64 Android builds using the Android Docker
environment, kdeorg/android-sdk, result in compilation failing with error:
> configure: error: Error! Cross compiling but no --with-cross-build option
> specified - please supply the path to an executable ICU's build root.
STEPS TO REPRODUCE
Follow steps at https://community.kde.org/Craft/Android
These are:
1. Download KDE Android SDK
> docker pull kdeorg/android-sdk
2a. Setup Craft in the container with persistence.
> docker run -ti --rm -v <your persistent craft path>:/home/user/CraftRoot
> kdeorg/android-sdk craft-bootstrap
2b. Select either ARM or ARM64 as target architecture.
3. Build any KDE project, kcoreaddons, kirigami, or ktrip. Do attempt to build,
don't use the pretend flag `-p`.
> docker run -ti --rm -v <your persistent craft path>:/home/user/CraftRoot
> kdeorg/android-sdk craft ktrip
OBSERVED RESULT
Compilation fails while configuring ICU, the first of libraries to be built.
> configure: error: Error! Cross compiling but no --with-cross-build option
> specified - please supply the path to an executable ICU's build root
EXPECTED RESULT
A smooth Craft build, or a request to install required project dependencies.
SOFTWARE/OS VERSIONS
Linux/KDE Plasma: KDE neon Testing Edition
KDE Plasma Version: 5.22.4
KDE Frameworks Version: 5.85.0
Qt Version: 5.15.13
ADDITIONAL INFORMATION
Kernel: Linux 5.11.0-25-lowlatency (64-bit)
While ICU attempts to compile, the following possibly related error is seen:
> *** Action: compile for libs/icu ***
> executing command: /home/user/CraftRoot/dev-utils/bin/python3
> /opt/android-ndk/build/tools/make_standalone_toolchain.py --install-dir
> /home/user/CraftRoot/tmp/android-arm-toolchain --arch arm --api 21
> WARNING:__main__:make_standalone_toolchain.py is no longer necessary. The
> $NDK/toolchains/llvm/prebuilt/linux-x86_64/bin directory contains
> target-specific scripts that perform
> the same task. For example, instead of:
>
> $ python $NDK/build/tools/make_standalone_toolchain.py \
> --arch arm --api 21 --install-dir toolchain
> $ toolchain/bin/clang++ src.cpp
>
> Instead use:
>
> $
> $NDK/toolchains/llvm/prebuilt/linux-x86_64/bin/armv7a-linux-androideabi21-clang++
> src.cpp
