@Sekhar Do you really have to use Qt4.8?
Also, this is really unclear: ""qt-everywhere-opensource-src-4.8.7 (arm-linux-gnueabihf)" compiler in "qt-5.2.0-x86"" - here is no compiler mentioned. So, which exact Qt version do you want to use? Qt4.8 or Qt5?

@Sekhar said in make[1]: *** [makefile:1624: obj/release/pcre_exec.o] Error 1:

std::tr1

As I expected, the compiler is to new. The source code was written in Pre-C++11 times, and the namespace std::tr1 no longer exists (or would have to be enabled by hand, depending on the compiler).

Basically i am the beginner for QT platform and my intention is to Develop a Basic QT application run on my BeagleBone Black("arm-linux-gnueabihf" based compiler) board that's why i am trying to build a make file by followed these Documents [http://thoughtwaves.com/](link url) and [http://thoughtwaves.com/?p=50](link url).

if you don't mind could you please suggest me the way how to developing and run a basic QT application on my BeagleBone Black board.

[jsulm]

@Sekhar Here for example: https://wiki.qt.io/BeagleBone_Black_Beginners_Guide
It uses Qt5.7, but I suggest to use the current stable version (5.13.1).

[Sekhar]

Error 1:
I will try to ofline-install QT5.5.1 on my Ubuntu12.04(32-bit) System. i tried to execute file it will shows
" bash: ./qt-opensource-linux-x64-5.5.1.run: cannot execute binary file "

if i was used these below commands :
$ chmod +x qt-opensource-linux-x64-5.5.1.run
$ ./qt-opensource-linux-x64-5.5.1.run

still it will show's same error.
" bash: ./qt-opensource-linux-x64-5.5.1.run: cannot execute binary file "

I doesn't understand why it will happens.
i was download from [https://mirrors.tuna.tsinghua.edu.cn/qt/archive/qt/5.5/5.5.1/qt-opensource-linux-x86-5.5.1.run](link url)

Error 2:
I was followed what "BeagleBone_Black_Beginners_guide " suggest those steps
in
step 2. Copy bbb image to workstation:

workstation@workstation:~/opt$ nc -l 19000|dd bs=1M of=bbb-with-ssl-and-icu-dev.img

it will shows on every time.

I tried more that 5 times nearly 3 hours but same result on every time.

[aha_1980]

@Sekhar

Ubuntu12.04(32-bit)

That is a pretty old OS - I can't guarantee that will work. And is the offline installer 32 bit too? Because you write both x86 and x64.

[jsulm]

@Sekhar You're trying to execute a 64bit binary on a 32bit OS, this is not going to work. You need 32bit Qt version. Also, why such an old Ubuntu version and such an old Qt version?!

[Sekhar]

@jsulm Sorry i forgot it. Error 1 solved. can you please give me solution for Error 2.

[jsulm]

@Sekhar You have issue two commands: one on your device and one on your workstation. Did you do both?

# This is done on workstation (host)
workstation@workstation:~/opt$ nc -l 19000|dd bs=1M of=bbb-with-ssl-and-icu-dev.img

# This is done on device, adapt it to your environment don't just copy paste as is (device file name and IP could be different)
root@Matilda:~# dd bs=1M if=/dev/mmcblk0|nc 192.168.7.1 19000

I had a problem on workstation.
already i was upload a image on above conversation.

[jsulm]

@Sekhar But did you issue the second command on the device also? Because without it the command on your workstation will timeout.

[Sekhar]

i tried on both workstation and beaglebone also but didn't response. Ok i will try it once again.
Nearly How much space(Memory) for this operation is required in my workstation(system).
thank you.

[jsulm]

@Sekhar said in make[1]: *** [makefile:1624: obj/release/pcre_exec.o] Error 1:

Depends on the size of the device partition.
Did you make sure you're using correct IP address?

[Sekhar]

@jsulm
Thanks for your vlauble time to spent with my problems solving.
that image file copied in my /opt/ folder.

now I am trying to do next step: mount that image, but it shows an error message like

in my vertual system had remaing 2GB space only, after copied this image file. that image file takes nearly 16GB.

[jsulm]

@Sekhar said in make[1]: *** [makefile:1624: obj/release/pcre_exec.o] Error 1:

If it is a virtual system you can resize the virtual hard disk and then resize the partition in your virtual system.

Regarding mount issue: try to specify file system type using -t parameter (use same file system type used on your device).

[Sekhar]

As i was installed Ubuntu 19.04 and i would bi tried these steps mentioned in the document [https://wiki.qt.io/BeagleBone_Black_Beginners_Guide](link url)
but at the 3 point(Preparing workstation) i got an error.... like

and if i was followed another documentation [http://thoughtwaves.com/?p=50](link url) and i got an error like

i was struggled last 2 months for interfacing QT with Beaglebone Black.
my intention is to developing and run a basic QT application on my BeagleBone Black board.

could you please tell me how can i slove this error.

[SGaist]

Start by stopping mixing Qt 4 and Qt 5 instruction sets.

Follow the Qt wiki instructions and only these.

[Sekhar]

@SGaist
if i was followed QT wiki instructions i got an error at the time of mount an image.

already asked is same query in the above conversation but some one told to specify the file system type using -t parameter
that's why i am using -o and -t

is there any other way to mount that iso. file. for move on next steps...

[aha_1980]

@Sekhar If you would post your console output as text, we could easily modify it and send it back to you. But as pic, that's impossible.

So just a rought template, the syntax is:

mount -t <filesystem-type> -o loop,<other parameters> <file.img> </path/to/mountpoint>

@aha_1980
thank you... it will working...
