Trouble building arm64-v8a android

[jheinz]

Hey everybody,

I've been using SFML for awhile, and recently I've been looking into creating android apps. Since I'm familiar with SFML, I thought I'd try out the experimental android port. I've managed to compile armeabi and armeabi-v7a targets, but I'm currently trying to figure out how to get arm64-v8a to compile. This is the output of make:

This is the file that generates the error, it appears that even editing it will not do anything (although I may be wrong):

If anyone has a clue how to get around this, that'd be awesome. Thanks!

Very late reply I know. I think the issue is that it is compiling with the 32 bit toolchain from the NDK, which does not define that type. I am having that exact problem right now building the dependencies (openal-soft). It is misleading as it is including the 64 bit headers.

I managed to get past this by downgrading my NDK to r10e, as it "just works" with that.
