How to cross-compile and run on Android. Please read to the end,
since there are important details further down regarding crash
avoidance and GPU support.
These notes were last updated on 4 Nov 2014, for Valgrind SVN
revision 14689/2987.
These instructions are known to work, or have worked at some time in
the past, for:
arm:
Android 4.0.3 running on a (rooted, AOSP build) Nexus S.
Android 4.0.3 running on Motorola Xoom.
Android 4.0.3 running on android arm emulator.
Android 4.1 running on android emulator.
Android 2.3.4 on Nexus S worked at some time in the past.
x86:
Android 4.0.3 running on android x86 emulator.
mips32:
Android 4.1.2 running on android mips emulator.
Android 4.2.2 running on android mips emulator.
Android 4.3 running on android mips emulator.
Android 4.0.4 running on BROADCOM bcm7425
arm64:
Android 4.5 (?) running on ARM Juno
On android-arm, GDBserver might insert breaks at wrong addresses.
Feedback on this welcome.
Other configurations and toolchains might work, but haven't been tested.
Feedback is welcome.
Toolchain:
For arm32, x86 and mips32 you need the android-ndk-r6 native
development kit. r6b and r7 give a non-completely-working build;
see http://code.google.com/p/android/issues/detail?id=23203
For the android emulator, the versions needed and how to install
them are described in README.android_emulator.
You can get android-ndk-r6 from
http://dl.google.com/android/ndk/android-ndk-r6-linux-x86.tar.bz2
For arm64 (aarch64) you need the android-ndk-r10c NDK, from
http://dl.google.com/android/ndk/android-ndk-r10c-linux-x86_64.bin
Install the NDK somewhere. Doesn't matter where. Then:
# Modify this (obviously). Note, this "export" command is only done
# so as to reduce the amount of typing required. None of the commands
# below read it as part of their operation.
#
export NDKROOT=/path/to/android-ndk-r<version>
# Then cd to the root of your Valgrind source tree.
#
cd /path/to/valgrind/source/tree
# After this point, you don't need to modify anything. Just copy and
# paste the commands below.
# Set up toolchain paths.
#
# For ARM
export AR=$NDKROOT/toolchains/arm-linux-androideabi-4.4.3/prebuilt/linux-x86/bin/arm-linux-androideabi-ar

export CC=$NDKROOT/toolchains/x86-4.4.3/prebuilt/linux-x86/bin/i686-android-linux-gcc
# For MIPS32

export CC=$NDKROOT/toolchains/mipsel-linux-android-4.8/prebuilt/linux-x86_64/bin/mipsel-linux-android-gcc

export LD=$NDKROOT/toolchains/aarch64-linux-android-4.9/prebuilt/linux-x86_64/bin/aarch64-linux-android-ld

# Do configuration stuff. Don't mess with the --prefix in the
# configure command below, even if you think it's wrong.
# You may need to set the --with-tmpdir path to something
# different if /sdcard doesn't work on the device -- this is
# a known cause of difficulties.
# The below re-generates configure, Makefiles, ...
# This is not needed if you start from a release tarball.

./configure --prefix=/data/local/Inst \
--host=aarch64-unknown-linux --target=aarch64-unknown-linux \
--with-tmpdir=/sdcard
# At the end of the configure run, a few lines of details
# are printed. Make sure that you see these two lines:
#
# For ARM:
# Platform variant: android
# Primary -DVGPV string: -DVGPV_arm_linux_android=1
#
# For x86:
# Platform variant: android
# Primary -DVGPV string: -DVGPV_x86_linux_android=1
#
# For mips32:
# Platform variant: android
# Primary -DVGPV string: -DVGPV_mips32_linux_android=1
#
# For ARM64 (AArch64):
# Platform variant: android
# Primary -DVGPV string: -DVGPV_arm64_linux_android=1
#
# If you see anything else at this point, something is wrong, and
# either the build will fail, or will succeed but you'll get something
# which won't work.
# Build, and park the install tree in `pwd`/Inst
#
make -j4
make -j4 install DESTDIR=`pwd`/Inst
# To get the install tree onto the device:
# (I don't know why it's not "adb push Inst /data/local", but this
# formulation does appear to put the result in /data/local/Inst.)
#
adb push Inst /
# To run (on the device). There are two things you need to consider:
#
# (1) if you are running on the Android emulator, Valgrind may crash
# at startup. This is because the emulator (for ARM) may not be
# simulating a hardware TLS register. To get around this, run
# Valgrind with:
# --kernel-variant=android-no-hw-tls
#
# (2) if you are running a real device, you need to tell Valgrind
# what GPU it has, so Valgrind knows how to handle custom GPU
# ioctls. You can choose one of the following:
# --kernel-variant=android-gpu-sgx5xx # PowerVR SGX 5XX series
# --kernel-variant=android-gpu-adreno3xx # Qualcomm Adreno 3XX series
# If you don't choose one, the program will still run, but Memcheck
# may report false errors after the program performs GPU-specific ioctls.
#
# Anyway: to run on the device:
#
/data/local/Inst/bin/valgrind [kernel variant args] [the usual args etc]
# Once you're up and running, a handy modify-V-rebuild-reinstall
# command line (on the host, of course) is
#
mq -j2 && mq -j2 install DESTDIR=`pwd`/Inst && adb push Inst /
#
# where 'mq' is an alias for 'make --quiet'.
# One common cause of runs failing at startup is the inability of
# Valgrind to find a suitable temporary directory. On the device,
# there doesn't seem to be any one location which we always have
# permission to write to. The instructions above use /sdcard. If
# that doesn't work for you, and you're Valgrinding one specific
# application which is already installed, you could try using its
# temporary directory, in /data/data, for example
# /data/data/org.mozilla.firefox_beta.
#
# Using /system/bin/logcat on the device is helpful for diagnosing
# these kinds of problems.
