c++ - Trying to compile .cpp with g++ for 64 bit windows -


first tried downloading after searching mingw64 windows. didn't work. while searching solution came across this, answer includes seems legit version of mingw64.

this being third or fourth mingw64 i've downloaded, happy see g++64.exe assumed take care of everything. doesn't, after compiling g++64 -o hello.exe -c hello.cpp , running hello error saying this version of [...]\hello.exe not compatible[...].

what doing wrong? i've tried -m64. there additional setting need change? should post g++64 -v?

your command wrong, you're not creating .exe file, object file need link produce executable. this:

g++64 -o hello.exe hello.cpp

the -c argument tells compiler compile not link code. can above in 2 steps, compile , link:

g++64 -c -o hello.o  hello.cpp g++64 -o hello.exe hello.o

css - Make div keyboard-scrollable in jQuery Mobile? -

from can tell, although jquery-mobile-powered pages can contain divs overflow set scroll or auto, , these divs can scrolled one-screen bar or mouse wheel, cannot scrolled using arrow keys, page-up/page-down, or home/end. instead, official "page" div (with data-role="page") absorbs input. perhaps other divs can't acquire focus, i'm not sure. is there way around this? edit: jsfiddle of simple example: https://jsfiddle.net/qogz0shx/ <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.4/jquery.min.js"></script> <script src="https://ajax.googleapis.com/ajax/libs/jquerymobile/1.4.5/jquery.mobile.min.js"> </script> <link rel="stylesheet" href="https://code.jquery.com/mobile/1.4.5/jquery.mobile-1.4.5.css"/> <style> #outer { overflow:scroll; height: 50vh; width: 50vw; } #inner { height: 500vh; width: 500vw; } ...
