Do you have a static libz.a installed (from zlib1g-dev) and all dependent static libraries? I think you're right about the static linking but this was just a quick test to see if SYSTEM_ZLIB=true worked with everything else as default.

I suspect you'll get the same failure with or without my patch (though you'll probably need the change to defines.h to get this far...)
SYSTEM_ZLIB is currently Mac only so I wouldn't expect to have got very far without your changes.
I'd guess you have STATIC_CXX set to true (the default apparently):
I didn't specify any other build options so it's using the default. BTW: I should mention that I don't have any issues with the patch proposed as it works as it does now because SYSTEM_ZLIB is false. It may be that there is follow-up to allow SYSTEM_ZLIB=true and static linking to work together. -Alan.
