No SetWindowLongPtrW in user32

[uranusjr]

I tried compiling the library with the hello world program, but could not get past compiling native-windows-gui v0.1.0. There are multiple errors, but they seem to boil down to one specific problem: unable to import GetWindowLongPtrW and SetWindowLongPtrW from user32.

I’m running Rust 1.13.0 MSVC on Windows 7 (32-bit) with C++ Build Tools (as advised on rustlang.org) and Windows 8 API installed.

(Sorry if this is a dumb problem; I’m not familiar at all with Windows.)

I've just checked the winapi rs docs for the definition of Get/SetWindowLongPtrW and it is only exported for "x86_64" aka 64 bits Windows.

Thank you for reporting this issue, I will add a fix that uses SetWindowLong if SetWindowLongPtr cannot be found and then It should work.

@uranusjr I've just pushed the fix on master, can you check if it work now? I tested it on a 32bits rust on my machine, but I just want to be absolutely certain there are no more ARCH bugs before I release another version.

[uranusjr]

Yup, master runs as expected. Thanks! 👍

There’s another problem: The exit_on_close: true attribute doesn’t seem to work. After I close the main window, cargo run is still executing, and I can see my program in the task manager (ctrl-shift-esc). I have to hit ctrl-c to terminate the program.

I have no idea if this is related though, so feel free to close this (and put this in a seperate issue).
