[Qt-embedded-interest] cross compilation error (cc1: error: unrecognized command line option "-m64")

[Balagopalakrishnan, Anand]

The ARM code sourcery tool chain does not support -m64 option. Even in gcc, this is really an undocumented feature. This option shouldn't get added as part of qmake.

Can you send your qmake.conf and config.status files?

Anand Balagopalakrishnan

Hi,

I am trying to build  am18xx-demo using qt-everywhere-opensource-src-4.6.0

I am using the following url to compile am18xx-demo

http://processors.wiki.ti.com/index.php/Qt_Framework_Demo_Setup

I got the following error on compiling "qt-everywhere-opensource-src-4.6.0"

arm-none-linux-gnueabi-gcc -c -pipe -m64 -fno-exceptions -O2 -fPIC -Wall -W -DQT_QWS_CLIENTBLIT -DQT_BOOTSTRAPPED -DQT_LITE_UNICODE -DQT_NO_CAST_FROM_ASCII -DQT_NO_CAST_TO_ASCII -DQT_NO_CODECS -DQT_NO_DATASTREAM -DQT_NO_GEOM_VARIANT -DQT_NO_LIBRARY -DQT_NO_QOBJECT -DQT_NO_STL -DQT_NO_SYSTEMLOCALE -DQT_NO_TEXTSTREAM -DQT_NO_THREAD -DQT_NO_UNICODETABLES -DQT_NO_USING_NAMESPACE -D_LARGEFILE64_SOURCE -D_LARGEFILE_SOURCE -I../../../mkspecs/qws/linux-x86_64-g++ -I. -I../../../include -I../../../include/QtCore -I../../../include/QtXml -I../../3rdparty/zlib -o .obj/release-static-emb-arm/adler32.o ../../3rdparty/zlib/adler32.c
cc1: error: unrecognized command line option "-m64"

make[1]: Leaving directory `/home/batsayan/junk/ui/qt-everywhere-opensource-src-4.6.0/src/tools/bootstrap'
make: *** [sub-tools-bootstrap-make_default-ordered] Error 2

What is the wrong?

The gcc version is

arm-none-linux-gnueabi-gcc (Sourcery G++ Lite 2009q3-67) 4.4.1

The configuration option is
./configure -opensource -static -no-qt3support -no-xmlpatterns -no-multimedia -no-phonon -no-phonon-backend -no-svg -no-webkit -no-javascript-jit -no-script -no-scripttools -no-declarative -qt-mouse-tslib -DQT_QWS_CLIENTBLIT -xplatform qws/linux-arm-g++ -embedded arm -confirm-license
