Compiling Qt 4.8.5 using mingw32 on windows7: “no such file or directory”

Question

I'm trying to build qt-4.8.5 (opensource) from source using mingw32 compiler on windows 7.

"configure" works fine, but compilation (mingw32-make) fails with this output:

D:\development\qt-4.8.5-mingw>mingw32-make

Ie:

g++: error: CreateProcess: No such file or directory                                                                            

Because g++ DOESN'T print which file it can't find, I'm not certain what could be causing this. I can call g++, gcc and mingw32-make from command line and they're in Path. I've removed VC directories, MS SDK directories, and this doesn't fix the problem either. This is a clean "install", I extracted tar.gz contents, and run configure without modifying anything. Adding mingw include path via -I switch to configure doesn't fix the problem.

How do I fix this?

Additional info :
g++ version: 4.7.1
mingw32-make version: 3.82.90

Answer 1

Figured it out. (Well, I still don't know what was causing this, but I know how to make it work).

Solution:

1. Place qt.conf into qt "bin" directory.

    [Paths] Prefix = d:/development/qt-4.8.5-mingw 

   Prefix is path of your qt installation (notice forward slashes).

2. Configure and compile using bat files:

   1. To configure:

       set QTDIR=D:\\development\\qt-4.8.5-mingw set QMAKESPEC=win32-g++ set PATH=D:\\development\\MinGW\\bin;D:\\development\\tools\\Perl32\\bin;D:\\development\\qt-4.8.5-mingw\\bin set PATH=%PATH%;c:\\Windows\\system32 set INCLUDE= set LIB= set CPATH= set CPLUS_INCLUDE_PATH= set LANG=en configure -opensource -openssl 

      You should put into path bin directory of 32bit perl, bin directory of mingw32 installation, and bin directory of qt installation. -openssl key is optional (I need this one).

   2. To compile:

       set QTDIR=D:\\development\\qt-4.8.5-mingw set QMAKESPEC=win32-g++ set PATH=D:\\development\\MinGW\\bin;D:\\development\\tools\\Perl32\\bin;D:\\development\\qt-4.8.5-mingw\\bin set PATH=%PATH%;c:\\Windows\\system32 set INCLUDE= set LIB= set CPATH= set CPLUS_INCLUDE_PATH= set LANG=en mingw32-make
