Porting/adb

adb and fastboot do not build out of the box for ppc64le on Debian. fitzsim documented the following workarounds:

android-libext4-utils

apt source android-libext4-utils
sed -i 's/\(mips64el\)/\1 ppc64el/g' android-platform-system-extras-*/debian/control
cd android-platform-system-extras-*/
dpkg-buildpackage -rfakeroot

android-platform-external-boringssl

apt source android-platform-external-boringssl

In libcrypto.mk, add -DOPENSSL_NO_ASM to the CFLAGS+= line.

dpkg-buildpackage -rfakeroot

Install the resulting packages.

android-platform-system-core

sed -i 's/amd64/ppc64el/g' android-platform-system-core-*/debian/control

In that same control file, replace versioned references to android-libunwind-dev with unversioned references to libunwind-dev

cd android-platform-system-core-*/
make -f debian/rules libbase.so liblog.so fastboot/fastboot adb/adb

You should now have working adb and fastboot binaries:

LD_LIBRARY_PATH=`pwd` ./adb/adb --help
LD_LIBRARY_PATH=`pwd` ./fastboot/fastboot --help
