configure command fails when trying to rebuild qt soureces

[gsanson]

Hi,

When I follow the steps to rebuikl the qt from sources in

http://www.wiki.xilinx.com/Zynq+Qt+and+Qwt+Base+Libraries-Build+Instructions

I get the following output when running the configure command

gsanson@ubuntu12:/opt/pkg/Qt/build/qt-everywhere-opensource-src-4.8.5$ ./configure -embedded arm -xplatform qws/linux-arm-gnueabi-g++ -little-endian -opensource -host-little-endian -confirm-license -nomake demos -nomake examples -prefix $ZYNQ_QT_INSTALL

Does anyone know what is happening and why? I get that this may be a 32/64 bit issue.

Dev Platform

Ubuntu 12.04 LTS 64bit

Thanks,

Hi ,

Please check if CROSS_COMPILE environment variable is set and cross-compiler is added to path.

bash> export CROSS_COMPILE=arm-xilinx-linux-gnueabi-
bash> export PATH=/path/to/cross/compiler/bin:$PATH

Hi,

Thanks for the response

Yes I have doen that that set but that is what is confusing. I've got everything set as suggested or how I thought they should be based upon the AR

Here is the list of installed cros compilers under the /opt directory

./pkg/petalinux-v2014.4-final/tools/linux-i386/arm-xilinx-gnueabi
./pkg/petalinux-v2014.4-final/tools/linux-i386/arm-xilinx-linux-gnueabi

./Xilinx/SDK/2014.4/gnu/arm/lin/i686-pc-linux-gnu/arm-xilinx-linux-gnueabi

Which one should be used?

And my envronment variable

CROSS_COMPILE=arm-xilinx-linux-gnueabi-

ARCH=arm

PETALINUX=/opt/pkg/petalinux-v2014.4-final

PATH=/opt/Xilinx/SDK/2014.4/gnu/arm/lin/arm-xilinx-linux-gnueabi/bin:/opt/Xilinx/SDK/2014.4/bin:/opt/Xilinx/Vivado/2014.4/bin:/usr/lib/lightdm/lightdm:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/opt/Xilinx/Vivado/2014.4/bin:/opt/Xilinx/SDK/2014.4/bin

ZYNQ_QT_BUILD=/opt/pkg/Qt/build

ZYNQ_QT_INSTALL=/opt/pkg/Qt/install

Any other ideas?

Thanks,

Gary

We can set crosscompiler path to either XSDK or Petalinux.

Looking in gcc documentation option  "-m64" generates code for a 32-bit or 64-bit environment.

Simply check if option (-m64)  is supported on host compiler.

<cross-compiler>-g++  -m64  hello.cpp

<cross-compiler>-g++  -m32  hello.cpp
