x-compile for Android/MIPS fails

Original issue 109 created by ulcica on 2012-08-03T11:51:31.000Z:

Use the android branch. Edit leveldb/jni/Application.mk

APP_ABI := mips

The ndk-build output:

Compile++ mips : leveldb <= builder.cc
In file included from ./port/port.h:18:0,
from ./db/filename.h:14,
from jni/.././db/builder.cc:7:

As far as I know, the Android branch is completely obsolete. All the Android-specific patches were moved to the main branch for the 1.5 release.

I just tried rebuilding with the NDK for ARM and this still works. The MIPS build fails for another reason (no implementation of atomic memory barrier function).

See attached a patch to solve this. The way to rebuild the library from upstream master branch is the following:

1/ $NDK/build/tools/make-standalone-toolchain.sh --install-dir=/tmp/ndk-mips --arch-mips

2/ PATH=/tmp/ndk-mips/bin:$PATH CC=mipsel-linux-android-gcc CXX=mipsel-linux-android-g++ TARGET_OS=OS_ANDROID_CROSSCOMPILE make -j4

Thanks for the patch. It fixes the MIPS build.

Thank you!

Just a note, the first command should be

1/ $NDK/build/tools/make-standalone-toolchain.sh --install-dir=/tmp/ndk-mips --arch=mips
