Hi
I'm a Android noob and need to build LMDB for Android. Is Android NDK the way to go?
https://developer.android.com/tools/sdk/ndk/index.html
Any tricks I should be aware of?
Cheers, -Kristoffer

Yep.

For simplicity's sake I put all the required flags into a shell script (I call it agcc) and just run "make CC=agcc" - you shouldn't need to change anything else in the Makefile then.
Do you have an example of agcc? I tried arm-linux-androideabi-gcc with --sysroot android-19 but the build fails.

Read the comments in mdb.c about MDB_DSYNC.
