Compiling a library with MingW

Question

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
      0 [main] us 0 init_cheap: VirtualAlloc pointer is null, Win32 error 487
AllocationBase 0x71110000, BaseAddress 0x71110000, RegionSize 0x1000, State 0x10
00
D:\Qt\Qt5.3.2\Tools\mingw482_32\msys\1.0\bin\sh.exe: *** Couldn't reserve space
for cygwin's heap, Win32 error 0

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.

Answer 1

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.

My bet is that you have Cygwin's "bin" directory in your PATH.
