Thanks Aaron. I will give this a go. I also wanted to know if you ever tried compiling this in the native source. I mean the whole android source.

I tried Aaron's post and ran into problems. I also tried making a Android.mk and got into undeclared values for __NR_shm* When I make here is what i get.. akrish9@akrish9-ws:~/setup/fio [master] $ make V=1 UNAME=Android cross_prefix=~/android-ndk-r8e/toolchains/x86-4.6/prebuilt/linux-x86_64/bin/i686-linux-android- This is not the problem here, but the preferred way to invoke cross compiles is now: make CROSS_COMPILE=/path/to/bin/i686-linux-android- Uname is deprecated. Now, the issue is that you can't run the Android toolchains directly out of the NDK, because the lib paths are wrong. What you need to do is build a standalone toolchain with ./build/tools/make-standalone-toolchain.sh from the NDK root dir. The script has a bunch of args to specify the versions and archs. That will generate a tar of a standalone toolchain: untar is somewhere and point CROSS_COMPILE to there, and it should build. Except that if you're targeting x86, it doesn't, due to a previously reported issue with some inline asm: arch/arch-x86-common.h:9:2: error: inconsistent operand constraints in an 'asm' I'm not sure what's going on there, but I don't speak x86 asm.
