you don't seem to have 'make' or 'qmake' in your PATH

jsulm

@Asha If you call ./configure then you're NOT doing out of source build!
Please read once more what I wrote before:

mkdir build_qt
cd build_qt
../qt5_sourcecode/configure...

Asha

@jsulm

shall I ask what is that ../qt5_sourcecode/configure....

jsulm

@Asha qt5_sourcecode is just a placeholder for the directory where you extracted Qt source code, replace it with the name of your Qt source code directory...
configure is what it is - configure command in Qt source code directory.

I explain this approach once more: you do NOT call configure inside the Qt source code directory, but from an empty build directory.

Asha

@jsulm

Yes,I extracted qt source code in my user directory(/home/beagle/)

After that I replaced it into a directory called qt-5.13(replaced via....mv qt-everywhere-src-5.13.1 ~/qt-5.13)

And calling the configure in this directory only.

Some more information here..

make --version
GNU Make 4.1
Built for x86_64-pc-linux-gnu

uname -srv
Linux 5.0.0-29-generic #31~18.04.1-Ubuntu

Which make
/usr/bin/make

echo $LD_LIBRARY_PATH
not displaying anything

Again, this is not how it works!
You do NOT call configure from the source code directory for out of source builds, but from an empty directory!
Again:

# Create an empty directory:
mkdir build_qt
# Go to that empty directory:
cd build_qt
# Call configure from the Qt source code directory:
../qt5_sourcecode/configure...

Asha

@jsulm pwd is qt-5.13,here I need to create directory?if yes ,I created and tried getting

bash : ./configure : No such file or directory

please go through this link https://forum.qt.io/topic/106766/can-we-change-the-compiler-in-qmake/28 I followed this pdf...

jsulm

@Asha said in you don't seem to have 'make' or 'qmake' in your PATH:

bash : ./configure : No such file or directory

Please read more carefully what I'm writing!
You need to use complete path (or relative) to configure!
That's why I wrote:

../qt5_sourcecode/configure

You can use absolute path instead of relative:

PATH_TO_YOUR_QT_SOURCE_DIRECTORY/configure

Asha

@jsulm

yes,I gave the hole path /home/beagle/qt-5.13/.configure

its starts configuring but not succeed...

After few minutes its stops with error

/home/beagle/qt-5.13/build_qt/qtbase/bin/qmake: error while loading shared libraries: libstdc++.so.6: cannot open shared object file: No such file or directory

Asha

but libstdc++.so.6 library is present in my system...

location is:

/usr/arm-linux-gnueabihf/lib/libstdc++.so.6

jsulm

@Asha said in you don't seem to have 'make' or 'qmake' in your PATH:

is present in my system

It needs to be present in your sysroot since you're cross compiling

Asha

@jsulm yes this library is present in sysroot also..

here is the attachement

Asha

when I gave the command below

qmake --version

The result is:

Qmake version 3.1
using Qt version 5.9.5 in /usr/lib/x86_64-linux-gnu

Is this any issue?

jsulm

@Asha said in you don't seem to have 'make' or 'qmake' in your PATH:

Is this any issue?

No, this is qmake from Qt delivered by Ubuntu.
qmake for your cross compiled Qt will be built when you cross compile Qt, but I don't know why you get that libstdc++ error.

Asha

@jsulm while getting that error,I inserted below line in my qmake.conf file

QMAKE_LIBDIR=/home/beagle/BBB/sysroot/usr/lib/arm-linux-gnueabihf

after this tried once again for configure...now facing the error

meta.o: file not recognized: File format not recognized
collect2:error: ld returned 1 exit status
Makefile:189: recipe for target '../bin/qmake'failed
make: ***[../bin/qmake] Error1

when I checked meta.o file with the command

file meta.o

The result is:
meta.o: ELF 64-bit LSB relocatable,x86-64,version 1(SYSV) ,with debug info,not stripped

Here is the attachement

Where other file are 32bit ELF with ARM.....

How to install this libraries libstdc++.so.6 and libgcc_s.so.1

jsulm

@Asha said in you don't seem to have 'make' or 'qmake' in your PATH:

How to install this libraries libstdc++.so.6 and libgcc_s.so.1

There is nothing to install: these files are part of your sysroot.

"meta.o: ELF 64-bit LSB relocatable,x86-64,version 1(SYSV) ,with debug info,not stripped" - this file is apparently built for Intel x86_64, not ARM.

Delete the content of the build directory, run configure and build again. And check your configure call (parameter you pass to it).

Take a look at this: https://wiki.qt.io/BeagleBone_Black_Beginners_Guide

SGaist

In addition to @jsulm, delete the build folder itself and re-create it. There might be hidden files created that can still influence.

Asha

@SGaist
tried with this also..Sir

getting same error Libstdc++.so.6:No such file or directory

Asha

This is the simple question where I am going to ask..

But I want clarification....

I need to configure on my host machine or target machine?(My ans is,on host machine is it correct?)

jsulm

@Asha said in you don't seem to have 'make' or 'qmake' in your PATH:

on host machine is it correct?

yes, cross compilation means that you build on host but for target device
