[CMake] 32-bit MinGW and Qt on 64-bit Windows

[Matthew Smith]

Hi everyone,

I recently installed the 64-bit version of Windows 7 on a computer which 
had previously been running 32-bit Vista (so, everything got wiped). I 
develop with Qt so I installed the standard Qt SDK (version 1.1.3 that 
was released last week; Qt libs version 4.7.4) and downloaded and 
installed the CMake installer (which is 32-bit). I discovered that I 
could not get CMake to run; it fails when checking for a working C compiler:

-- The C compiler identification is GNU
-- The CXX compiler identification is GNU
-- Check for working C compiler: C:/QtSDK/mingw/bin/gcc.exe
-- Check for working C compiler: C:/QtSDK/mingw/bin/gcc.exe -- broken
CMake Error at C:/Program Files x86/CMake 
2.8/share/cmake-2.8/Modules/CMakeTestC
Compiler.cmake:52 (MESSAGE):
   The C compiler "C:/QtSDK/mingw/bin/gcc.exe" is not able to compile a 
simple
   test program.

   It fails with the following output:

    Change Dir: C:/Users/Yusuf Smith/hg/qtm-1.4/CMakeFiles/CMakeTmp



   Run Build Command:C:/QtSDK/mingw/bin/mingw32-make.exe
   "cmTryCompileExec/fast"

   C:/QtSDK/mingw/bin/mingw32-make.exe -f

   C:/QtSDK/mingw/bin/mingw32-make.exe: Interrupt/Exception caught (code =
   0xc0000005, addr = 0x41f96e)





   CMake will not be able to correctly generate this project.
Call Stack (most recent call first):
   CMakeLists.txt:1 (project)


-- Configuring incomplete, errors occurred!

I found an earlier answer that having a directory containing parentheses 
in the search path may cause failure, and I had altered the path to 
include Vim and CMake which are both in "c:\Program Files (x86)", so I 
reinstalled these in another directory, "c:\Program Files x86" and 
changed my path accordingly. I still have this failure, however.

Also, spaces in directory names have been suggested as a problem, but my 
home directory had the same name under Vista and my program built fine 
then. This has all happened since the upgrade.

Does anyone know what the problem is? I cannot be the only one having 
this problem with the standard Qt SDK. Apart from CMake, my whole stack 
is from the Qt SDK.

Matt Smith
