I am trying to compile a library using MingW, but when I ./configure nothing really happens.
I read that I need to install MSYS, which I did, just to get a post install output saying:
D:\Qt\Qt5.3.2\Tools\mingw482_32\msys\1.0\postinstall>..\bin\sh.exe pi.sh

D:\Qt\Qt5.3.2\Tools\mingw482_32\msys\1.0\postinstall>pause
Press any key to continue . . .
after which trying to run opens up a command prompt which closes immediately, before I get to see what it says.
I just got the same problem, the MSYS that came with "stock" MinGW worked, but the standalone I tried installing to work alongside the MinGW installed by Qt did not. Then I noticed msys-1.0.dll - allegedly the same version has different sizes, copied the one from the stock MinGW MSYS over to the standalone MSYS and it worked - I was able to configure MSYS to work with Qt's MinGW install.
Seems like the MSYS standalone installer comes with the wrong DLL.
