Ya it's really weird.  XML_LIBS doesn't pickup -lz in my environment for some reason (OSX 10.13.6).

Hmm interesting. What’s the configure output of libxml2 for for zlib? It should be the following if it finds zlib in the NDK, which should be adding -lz to the linker flags:

Checking zlib

checking for zlib... yes

Also if you look at config.log you should see an entry like the following:

XML_LIBS='-lxml2 -lz     -lm '

You could try adding --with-zlib=... in 14-libxml2.sh in the toolchain to specify the path to libz.

We’ve built the toolchain on multiple machines here without seeing this issue, so I’m interested to find out what this is caused by.

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
