Does not build on GCC 4.9.2-10 / armv7l

[notlion]

I'm getting some errors when building the example with GCC 4.9 on linux. It looks like pybind::ssize_t is actually int on 32-bit, so overloading int_ with both on 32 bit architectures actually triggers an error.

Hi,

can you please check if it works with the latest version?

Thanks,

Closing this ticket as the underlying code has been completely rewritten to avoid these sorts of issues.

Please reopen if you are still having problems with compilation on arm.

Yup builds successfully on ARM now. Thanks very much for the fix!

great to hear -- thanks for checking!
