Hi, i was reconfiguring my qt sources with

Quoted

configure -debug-and-release -shared -no-fast -exceptions -no-accessibility -stl -plugin-sql-sqlite -plugin-sql-odbc -platform win32-g++ -qt-zlib -qt-libpng -qt-libmng -qt-libtiff -qt-libjpeg -dsp -vcproj -incredibuild-xge -qmake -process -rtti -openssl -qdbus -arch windows -qt-style-windows -qt-style-windowsxp -qt-style-windowsvista -qt-style-plastique -qt-style-cleanlooks -qt-style-motif -qt-style-cde

And I've got this output

Quoted

(...) cut
QMAKESPEC...................win32-g++ (commandline)
Architecture................windows
Maketool....................mingw32-make
Debug symbols...............yes
Accessibility support.......no
STL support.................yes
Exception support...........yes
RTTI support................yes
MMX support.................no
3DNOW support...............no
SSE support.................no
SSE2 support................no
OpenGL support..............yes
Direct3D support............no
OpenSSL support.............yes
QDBus support...............yes
Qt3 compatibility...........yes
(...) cut

My question is, how to enable the mmx, 3dnow, sse, sse2, direct3d support and how to use them?

not sure, but I think configure figures these out depending on the hardware you have? so if your cpu supports it it will be enabled.

So my AMD Turion™ 64 (2x1.6Ghz) does not support MMX ?

I don't believe it! That must be something else.

if found this piece of code in C:\Qt\4.3.3\tools\configure\configureapp.cpp

Source code

else if (part == "SSE2")
        available = (dictionary.value("QMAKESPEC") != "win32-msvc") && (dictionary.value("QMAKESPEC") != "win32-g++");
    else if (part == "3DNOW" )
        available = (dictionary.value("QMAKESPEC") != "win32-msvc") && (dictionary.value("QMAKESPEC") != "win32-icc") && findFile("mm3dnow.h") && (dictionary.value("QMAKESPEC") != "win32-g++");
    else if (part == "MMX" || part == "SSE")
        available = (dictionary.value("QMAKESPEC") != "win32-msvc") && (dictionary.value("QMAKESPEC") != "win32-g++");

if set QMAKESPEC to win32-msvc2005 all these features will enable.

So you can code punk?
