problem in running Qt app on nanoPC-T2

jsulm

@MhM93 Well, it tells you what is wrong: one of the shared libraries your application needs has a wrong version.
Do

ldd test2

to see which libraries are needed. You probably need to deploy your app properly to your target, means: copy needed libraries as well. For more information see: http://doc.qt.io/qt-5/linux-deployment.html

root@NanoPC-T2:/# ldd ./test2
    not a dynamic executable

jsulm

@MhM93 What does

file test2

say?

MhM93

[sorry for delay, last day I can not access my device to test. so sorry]
file test2 is show this result.
test2: ERROR: ELF 32-bit LSB executable, ARM, EABI5 version 1 (SYSV), dynamically linked, interpreter /lib/ld-linux-armhf.so.3 error reading (Invalid argument)

It said 32 bit compiler, when I download the gcc I extract gccx64
git clone https://github.com/friendlyarm/prebuilts.git
sudo mkdir -p /opt/FriendlyARM/toolchain
sudo tar xf prebuilts/gcc-x64/arm-cortexa9-linux-gnueabihf-4.9.3.tar.xz -C /opt/FriendlyARM/toolchain/

this is my output for this command:

but in qt :![image] )

when I attach the compiler in the ABIs write : arm-linux-generic-elf-32

MhM93

could any one help me?
I am confused

jsulm

@MhM93 "It said 32 bit compiler, when I download the gcc I extract gccx64" - the compiler itself is a x86_64 (64bit) binary - this does not mean that it generates 64bit binaries. You are building for ARM 32bit, so it generates ARM 32bit binaries.

You should do this (as I suggested before) on your target device:

ldd ./test2

It will should you which libraries are used by your executable.

"./test2: error while loading shared libraries: ./test2: unsupported version 9813 of Verneed record" - says that one of the libraries on your target has the wrong version number.

MhM93

Hi and thanx for reply, I do that if you see above post:

how to fix thislibrary version?

@MhM93 said in problem in running Qt app on nanoPC-T2:

Verneed record

Something is wrong with your executable. Can you show the whole build log (compiler output)?

MhM93

this is my file:
https://ufile.io/l2wkq
I first wrote it in qt, then compile it

jsulm

@MhM93 I'm not going to build this (I would need to install the same build tools first), so please post the build log...

MhM93

@jsulm :these links are my build tools
