Thanks Diago for the answer.

We are using our own zlib library. The fact is that without changing a 
line of code in our projet it compiles perfectly using 5.9.8, so the SDK 
seems to have everything needed.

I ended up replacing plugins/platform in 5.9.8 with the one from my 
5.9.9 build and that fixed my problem at least.
