How to cross-compile for Android.
|
|
|
|
This is known to work at least for Android 3.0 running on a Motorola
|
|
Xoom. Other configurations and toolchains might work, but haven't
|
|
been tested. Feedback is welcome.
|
|
|
|
You need the android-ndk-r5c native development kit. Install it
|
|
somewhere. Then do this:
|
|
|
|
# Maybe not all of these are necessary -- I'm just being cautious.
|
|
#
|
|
export AR=/path/to/android-ndk-r5c/toolchains/arm-linux-androideabi-4.4.3/prebuilt/linux-x86/bin/arm-linux-androideabi-ar
|
|
export CPP=/path/to/android-ndk-r5c/toolchains/arm-linux-androideabi-4.4.3/prebuilt/linux-x86/bin/arm-linux-androideabi-cpp
|
|
export LD=/path/to/android-ndk-r5c/toolchains/arm-linux-androideabi-4.4.3/prebuilt/linux-x86/bin/arm-linux-androideabi-ld
|
|
export CXX=/path/to/android-ndk-r5c/toolchains/arm-linux-androideabi-4.4.3/prebuilt/linux-x86/bin/arm-linux-androideabi-g++
|
|
export CC=/path/to/android-ndk-r5c/toolchains/arm-linux-androideabi-4.4.3/prebuilt/linux-x86/bin/arm-linux-androideabi-gcc
|
|
|
|
# Configure. This will build a Valgrind that needs to go in
|
|
# /data/local/Inst on the device and that uses /data/local/tmp
|
|
# as the tmp dir on the device. This means it can operate on
|
|
# non-rooted (production) devices.
|
|
#
|
|
|
|
cd trunk
|
|
./autogen.sh
|
|
|
|
CPPFLAGS="--sysroot=/path/to/android-ndk-r5c/platforms/android-3/arch-arm" \
|
|
CFLAGS="--sysroot=/path/to/android-ndk-r5c/platforms/android-3/arch-arm" \
|
|
./configure --prefix=/data/local/Inst \
|
|
--host=armv7-unknown-linux --target=armv7-unknown-linux \
|
|
--with-tmpdir=/data/local/tmp
|
|
|
|
|
|
# At the end of the configure run, a few lines of details
|
|
# are printed. Make sure that you see these two lines:
|
|
#
|
|
# Platform variant: android
|
|
# Primary -DVGPV string: -DVGPV_arm_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
|
|
make 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)
|
|
/data/local/Bin/valgrind [the usual args etc]
