| 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] |
