Hey Frederik,

Having some trouble with the last stage of your build script in tools-android.  Seems to be an issue linking zlib and libxml2.  I'm going to take a look but i think it should be dynamically linked with the android system zlib...

Hi Jordan,

Just wanted to follow up on this:

It looks like Google also offers prebuilds of newer clang releases that should include the fix above:

https://android.googlesource.com/platform/prebuilts/clang/host/

I haven’t fully figured out how to integrate these in the NDK (some info here) but it might be easier than doing a full build yourself.

I managed to write a script that integrates the latest Clang prebuilt (r353983d) into the NDK (r20) by performing the same steps as Clang.install() in checkbuild.sh:

https://github.com/gnustep/tools-android/blob/master/install-ndk.sh

This along with switching to the gold linker lets me use the gnustep-2.0 runtime for both arm32 and arm64 on Android. I thought this may be useful to you as well.

Frederik
