An "exec format error" implies the actual executable file is corrupt, or for a different architecture.

You might check it with file qmake , to see what it says it is.

Hi,

The path shown there is within the sysroot meaning the root filesystem for your target. Therefore the binaries in there are built for your target architecture.

Okay , Thank you @JonB , @SGaist for your valuable response.
I want to complile the qt application code on ubuntu desktop through for Imx6 architecture. so i created the toolchain SDK with help of yocto.

As per your suggestion if check it with file qmake output is as follow:
qt5/qmake: ELF 32-bit LSB executable, ARM, EABI5 version 1 (GNU/Linux), dynamically linked, interpreter /lib/ld-linux-armhf.so.3, for GNU/Linux 3.2.0, BuildID[sha1]=a8d35a7ec22c1c368ba4b9906dc9cd880f146834, stripped

Did i done wrong while toolchain creation in yocto?

Looks like that. Then you cross compile Qt you should get tools like qmake compiled for HOST architecture, not target architecture as you execute them on host machine when cross compiling your apps.

I have created toolchain by following settings:
MACHINE ??= 'imx6ull14x14evk' in local.conf
do i need to change it ?

@Rohit39 Did you search for qmake outside of "sysroots" folder (but inside /opt/fsl-imx-x11/4.9.88-2.0.0)?

Rohit39 · 12 Mar 2021, 07:15

@jsulm qmake file location is : /opt/fsl-imx-x11/4.9.88-2.0.0/sysroots/cortexa7hf-neon-poky-linux-gnueabi/usr/bin/qt5

and sysroots folder contains as follows:
cortexa7hf-neon-poky-linux-gnueabi x86_64-pokysdk-linux

So, there is no other qmake?
Did you try

find /opt/fsl-imx-x11 -name qmake

?

@jsulm Thank you for your response.
if do find /opt/fsl-imx-x11 -name qmake output is as follow:

first one is directory and last two are executable with following information

@Rohit39 Then it looks like host tools were not generated or installed. But I'm not Yocto expert.

Take a look at this article, it talks about building a SDK targeted at cross-compilation with Qt.

@SGaist I followed same link. but not able to produced qmake for x86 platform

SGaist · 15 Mar 2021, 06:10

What exactly did you do ?

Rohit39 · S SGaist 12 Mar 2021, 20:33

@SGaist I have followed first
$bitbake meta-toolchain-qt5
but it throws an error :
Error: Transaction check error:file /opt/fsl-imx-x11/4.9.88-2.0.0/sysroots/x86_64-pokysdk-linux/environment-setup.d conflicts between attempted installs of nativesdk-cmake-3.8.2-r0.x86_64_nativesdk and nativesdk-qtbase-tools-5.9.4+git0+0d9208cecb-r0.x86_64_nativesdk
Its for Rocko version.
and about to follow steps as below from doc
inherit populate_sdk_qt5 == [in recipe image]
$bitbake -c populate_sdk <image-name>

so its not generating qmake file for x86 architecture.

The versions of the two clashing packages looks pretty old...

Do you mean Yocto version: Rocko Right?

I was thinking about both cmake and Qt versions.
